Technology Preview releases are not supported with Red Hat production service-level agreements (SLAs) and might not be functionally complete, and Red Hat does NOT recommend using them for production. - rhool Oct 27 '17 at 15:46. An Istio ingress gateway is provided as part of your Istio on GKE installation. Above we can see the control/data plane API pods: Mixer, Pilot, and Ingress/Egress. Fine-grained control of traffic behavior with rich routing rules, retries, failovers, and fault injection. 8 and I want to finalize the use-cases before I submit an updated proposal. There is no big philosophy when one keeps in mind that Ingress/Egress-terms were originally explaining OSI L2 features. Ingress and egress routing; Resilency. com), the rules apply to that host. Fine-grained control of traffic behaviour with rich routing rules, retries, fail-overs and fault injection. When you deploy Istio you can opt to have all egress traffic blocked and create specific rules to permit traffic to specific endpoints. If you are not familiar with Ingresses in Kubernetes you might want to read the Kubernetes user guide. For example, Istio exposes a set of APIs that allows you to set fine-grained traffic rules. provisioning ingress, egress, edge layers or hardware LBs. If you add an ingress or egress gateway, they are under your control, and they aren't modified during the automatic upgrade. Built a simple HTTP based network function to demonstrate running containerized NF on Istio (0. Where Kubernetes/OpenShift itself gives you default round-robin load balancing behind its service construct, Istio allows you to introduce unique and finely grained routing rules among all services within the mesh. - Automatic metrics, logs, and traces for all traffic within a cluster, including cluster ingress and egress. Data can be streamed in real time or ingested in batches. In an out-of-the-box Istio-enabled environment, traffic is routed within and between the clusters of pods based on internal IP tables. An ingress gateway works with a service mesh such as Istio to route traffic and applies cluster access rules as simple as whitelist / blacklist created by the administrator. Istio and App Mesh both use Envoy as a data plane. It controls traffic coming and going from the Mesh and allows us to apply monitoring and routing rules from Istio Pilot. io To learn how to participate in our overall community, visit our community page In this README: Introduction Repositories Issue management In addition, here are…. The use of a gateway enables supplementary controls, such as using Kubernetes network policy, which can be configured to restrict all egress from the cluster except for traffic originating from the Egress Gateway. Ingress and Egress Envoys. Then a frame - mind NOT a packet - from a PC1 to the switch port 1 is ingress and the same frame from 24 to PC2 is egress. In Istio v0. The purpose of the sidecar proxy is to route, or proxy, traffic to and from the container it runs alongside. Ingress resource only supports rules for directing HTTP traffic. Technology Preview releases are not supported with Red Hat production service-level agreements (SLAs) and might not be functionally complete, and Red Hat does NOT recommend using them for production. io/docs/tasks/egress. The latest Tweets from James Brook (@james_brook). Egress gives you the power to bypass those IP tables, either based on Egress rules or for a range of IP addresses. If a host is provided (for example, foo. Tracing is most useful when it is possible to trace across an application. In this webinar we'll discuss the following traffic management topics:. - A pluggable policy layer and configuration API supporting access controls, rate limits and quotas.

Trusting Istio. 7 square feet. In our new journey, we show how you can modify and deploy the sample microservices application on Istio and use Envoy sidecars to enable the framework features in the application, as well as allow the application to connect to external services using egress Envoy. Developed in collaboration with the Spring Team at Pivotal, this project implements familiar Spring idioms and abstractions to bring the benefits of Spring and Spring Boot to Java developers using GCP services. Before deploy istio, you can modify the istio-demo. This topic describes how to use standard Istio route rules to control ingress TCP traffic Background information. We have this listed for beta support in 1. In Linkerd, namerd is a centralized service that manages to routing tables and service discovery. From the Istio website core functionality is defined as: Automatic load balancing for HTTP, gRPC, WebSocket, and TCP traffic. Prepare Dynatrace tokens Get a Platform-as-a-Service token to query the list of communication endpoints for the OneAgent. Envoy proxies inbound requests to the Istio Mixer service via a GRPC call. Each rule allows traffic which matches both the to and ports sections. The minimum egress window opening is 20” wide. • Fine-grained control of traffic behavior with rich routing rules, retries, failovers, and fault injection. As a developer, you don't want to. At a high level, Istio helps reduce the complexity of these deployments, and eases the strain on your development teams. com is not reachable without an appropriate egress rule. 8 and I want to finalize the use-cases before I submit an updated proposal. By default, istio blocks the cluster from making outbound requests. Notice that Istio CA will have created a secret of type istio. local"), Istio will interpret the short name based on the namespace of the rule, not the service. Fine-grained control of traffic behavior with rich routing rules, retries, failovers, and fault injection. Whether you choose automatic or manual sidecar injection of the Istio Proxy, Istio's egress rules currently only support HTTP and HTTPS requests. This is happening because, by default, Istio blocks unexpected outgoing requests (in this case, Istio is blocking your web application from communicating with Auth0 to get details about who logged in). More than 1 year has passed since last update. Istio Egress: Exit Through the Gift Shop This guide to using Istio with Red Hat OpenShift and Kubernetes shows you how to make microservices development easier, improving performance, tracing, and. In this case, Istio-ize Egress. You’ll learn how Istio features such as traffic flow management, access policy.

Istio provides automatic metrics, logs, and traces for all traffic within a cluster, including cluster ingress and egress. The next section will teach you how to fix that. Envoy proxies inbound requests to the Istio Mixer service via a GRPC call. The second most important feature of Cilium is its custom network policies which operate on Layer 7, giving us the ability to have enforcements on both ingress and egress. Taken the various guides for deploying Calico and Istio on Kubernetes to generate this one pager. - Upcoming changes in App Network Security with Istio. Many service mesh implementations use a sidecar proxy to intercept and manage all ingress and egress traffic to the instance or pod. Often vendors will require whitelisting of IPs to gain access to a service. A distributed tracing platform allows you to understand what happened from service to service for individual ingress/egress traffic. local"), Istio will interpret the short name based on the namespace of the rule, not the service. In one of my previous posts, I showed how to install Istio on minikube and deploy the sample BookInfo app. Configuring Zero Trust Networking with Kubernetes, Istio and Calico. Prepare Dynatrace tokens Get a Platform-as-a-Service token to query the list of communication endpoints for the OneAgent. There are several options to allow your service to connect externally: Egress rules prevent outbound calls. # Will set the value with same name in istio config map - pilot needs to be restarted to take effect. CONCLUSION. This is very much like the traditional load balancing we know:. We have this listed for beta support in 1. The Voter API makes external calls to its backend services, using two alternate protocols, MongoDB Wire Protocol ( mongodb:// ) and RabbitMQ AMQP ( amqps:// ). When you upgrade GKE, Istio on GKE and all default resources including the default ingress gateway are upgraded automatically. Automatic metrics, logs and traces for all traffic within a cluster, including cluster ingress and egress. It shows a visual model of the individual components in a service mesh that hopefully helps you in understanding and using Istio. 0 and incremental improvements to all the main feature groups.

Download the bundle istio-istio_-_2019-02-04_21-25-20. Istio Egress and Ingress. This proxy ensures enforcement of traffic rules, security policies and collects observability data (logs, metrics, tracing) from each deployment. The openstack cloud-provider can use the openstack LBaaS API to create loadbalancers and add/remove VIP endpoints corresponding to kubernetes loadbalancer service types. An Istio ingress gateway is provided as part of your Istio on GKE installation. By default this must be *. Istio is designed for extensibility and meets diverse deployment needs. Istio ignores Kubernetes services, since Kubernetes services can only do round-robin load balancing. Couple that with the transitional problems associated with external firewalls wanting fixed inbound IP rules, but the cloud has no fixed IP's, and you have a challenge. Automatic metrics, logs, and traces for all traffic within a cluster, including cluster ingress and egress. Intermediates between Istio and back ends, under operator control Support for rules, policies, mtls encryption. However, network policies in Kubernetes don't work "out-of-the-box" and the network provider must support it.

Ingress and egress. io for in-depth information about using Istio. Then a frame - mind NOT a packet - from a PC1 to the switch port 1 is ingress and the same frame from 24 to PC2 is egress. It does all this without requiring developers to make changes to application code by building on earlier work from IBM, Google and Lyft. If this is not the case, e. Envoy proxies inbound requests to the Istio Mixer service via a GRPC call. This is happening because, by default, Istio blocks unexpected outgoing requests (in this case, Istio is blocking your web application from communicating with Auth0 to get details about who logged in). The Istio gateway is the same Envoy proxy, only this time it’s sitting at the edge. The use of a gateway enables supplementary controls, such as using Kubernetes network policy, which can be configured to restrict all egress from the cluster except for traffic originating from the Egress Gateway. It shows a visual model of the individual components in a service mesh that hopefully helps you in understanding and using Istio. Istio implements service mesh architecture using a sidecar proxy pattern. Istio Egress: Exit Through the Gift Shop This guide to using Istio with Red Hat OpenShift and Kubernetes shows you how to make microservices development easier, improving performance, tracing, and. The ratings are displayed as stars for each review. Wait for all of your pods to reach a “Running” status before continuing. In Part II of this series, we learned to use Istio egress rules to control access to…. Mixer is the brains of Istio. • defines the rules that control how requests for a service are routed within an Istio service mesh • routing logic, load weighting, chaos injection • DestinationRule. [This is part ten of my ten-part Introduction to Istio. Egress is an antonym of ingress. The acceptance criteria were based on correctness and performance, both of these could be obtained just via tracing data 4. It does this by "deploying a sidecar proxy throughout your environment". It was launched by Google, IBM, and Lyft in 2016 and has been steadily becoming part of the cloud native toolbox. You'll learn how Istio features such as traffic flow management, access policy. As a site reliability engineer, you will want to enforce both ingress and egress rules. Visit istio. without complicate command as above. Ingress and egress. An Istio ingress gateway is provided as part of your Istio on GKE installation. The minimum opening area of the egress window is 5. If both ingress and egress are omitted, the rule has no effect. Users can then use standard Istio rules to control HTTP requests as well as TCP traffic entering a Gateway by binding a VirtualService to it. CF-APPS-DOMAIN. local”), Istio will interpret the short name based on the namespace of the rule, not the service. 今回は Istioを用いて、Blue Green Deployment と Canary の実施方法を試してみた。 特に Canary に関しては、Vampという素晴らしいツールが DC/OS には存在するが、Kubernetes の方はalpha だし、決定版の. More than 1 year has passed since last update. Istio provides an easy way to create a network of deployed services with load balancing, service-to-service authentication, monitoring, and more, without requiring any changes in service code. istio有三种流量管理的规则类型:Route Rules, Destination Policies, Egress Rules。 Route Rules. 0 Authorization Metric hètüS Denier Scrvicccontrol Rbacconfig "I-Ittpapispecstdio Envoyfiltèi' Logent ry Rule Dèdstinatlonrule Servicerole. Rules defined for services that do not exist in the service registry will be ignored. This includes all UDP, ICMP and IPv6 traffic. Istio can also be used to enforce compliance rules, defining ACLs between services to allow only authorized services to talk to each other. Unlike Kubernetes Ingress, Istio Gateway only configures the L4-L6 functions (for example, ports to expose, TLS configuration). An Egress Gateway (see Figure 3) is a dedicated Istio proxy through which all egress traffic passes - a single exit point from the mesh. They worked seamlessly together and the amount of iptables rules reduced dramatically. I created few egress rules in my cluster and would like to verify that they were applied properly. Notice that Istio CA will have created a secret of type istio. Istio provides automatic metrics, logs, and traces for all traffic within a cluster, including cluster ingress and egress. This, the final post in this series, is a recap. ingress includes inbound traffic whitelist rules; egress includes outbound traffic whitelist rules; In order to go into further detail, let's analyze three basic network policies. In our new journey, we show how you can modify and deploy the sample microservices application on Istio and use Envoy sidecars to enable the framework features in the application, as well as allow the application to connect to external services using egress Envoy. In some cases, the default gateway is not configured properly. with Istio and Kiali Alissa Bonas Defining a Gateway ingress/egress to enable traffic • Rules for how requests to a service are routed within service mesh. It controls traffic coming and going from the Mesh and allows us to apply monitoring and routing rules from Istio Pilot. * initial implementation of TCP support in egress rules * use 0. While Istio’s main focus is management of traffic between microservices inside a service mesh, Istio can also manage ingress (from outside into the mesh) and egress (from the mesh outwards) traffic. Calico is an open-source project to manage and enforce network policy of the cluster and it comes built-in in the latest google container releases. This is very much like the traditional load balancing we know:. What is really interesting about the. There are several versions of the ratings. And we also hope we can support running without istio injection. Jan 17, 2019 • admin • Category: Coreos Istio Calico. Without a doubt you should likely upgrade from earlier versions to take advantage of these improvements in your Kubernetes clusters. Wait for all of your pods to reach a "Running" status before continuing. Prepare Dynatrace tokens Get a Platform-as-a-Service token to query the list of communication endpoints for the OneAgent. Check out the entire list of benefits here. Istio is writing its own component to take user configuration and to store it and to validate it, to persist it, to store it and to send it into pilot, and that'll just be another stream of. Wait for all of your pods to reach a “Running” status before continuing. The former have an hour and $/gb pricetag associated with them, whereas the IG's do not. The main scenario pertaining to istio integration with openstack is the openstack cloud-provider's support for implementing kubernetes loadbalancer objects. Unlike Kubernetes Ingress, Istio Gateway only configures the L4-L6 functions (for example, ports to expose, TLS configuration). Like in this canary example, these rules can be defined with the same declarative Istio building blocks. Safer Service-To-Service Communications. 0 in Ubuntu16. Wait for all of your pods to reach a "Running" status before continuing. Kiali works with Istio to visualize your service mesh topology to provide visibility into features like circuit breakers, request rates, and more. A pluggable policy layer and configuration API supporting access controls, rate limits and quotas. Istio supports many other traffic management rules beyond traffic splitting, including content-based routing, timeout and retries, circuit breaking, and traffic mirroring for testing in production. CF-APPS-DOMAIN. Automatic metrics, logs, and traces for all traffic within a cluster, including cluster ingress and egress. Using Istio egress rules. We have this listed for beta support in 1. At a high level, Istio helps reduce the complexity of these deployments, and eases the strain on your development teams. Here's the 30,000-foot view of how a sidecar container works with Kubernetes and Minishift: Once you've started your Minishift instance, you create a project for Istio (let's call it "istio-system"), and you install and start all of the Istio-related components. So they are always switch port related. Before deploy istio, you can modify the istio-demo. This application uses the ratings microservice to fetch book ratings, a number between 1 and 5. The previous step deployed the Istio Pilot, Mixer, Ingress-Controller, Egress-Controller and the Istio CA (Certificate Authority). Technology Preview releases are not supported with Red Hat production service-level agreements (SLAs) and might not be functionally complete, and Red Hat does NOT recommend using them for production. Defining an Istio Egress. By default, istio blocks the cluster from making outbound requests. Safer Service-To-Service Communications. A configurable policy layer and API supporting access controls, rate limits, and quotas. There is no big philosophy when one keeps in mind that Ingress/Egress-terms were originally explaining OSI L2 features. In context|astronomy|lang=en terms the difference between ingress and egress is that ingress is (astronomy) the entrance of the moon into the shadow of the earth in eclipses, or the sun's entrance into a sign, etc while egress is (astronomy) the end of the apparent transit of a small astronomical body over the disk of a larger one. One of the four IP addresses, the one shown below, associated with the Forwarding rule, will be associated with the front-end of the load balancer. While Istio's main focus is management of traffic between microservices inside a service mesh, Istio can also manage ingress (from outside into the mesh) and egress (from the mesh outwards) traffic. Istio can also be used to enforce compliance rules, defining ACLs between services to allow only authorized services to talk to each other. The egress window must have a glass area of not less than 8% of the total floor area of room(s) for which it is servicing, to allow the minimum amount of sufficient natural light. The goal of this abstraction layer is to provide an easy-to-consume API that can be implemented by many different service mesh implementations (e. clusters and apps, without ingress and egress of data in clusters and apps. Istio Use Cases. The openstack cloud-provider can use the openstack LBaaS API to create loadbalancers and add/remove VIP endpoints corresponding to kubernetes loadbalancer service types. > a framework different from egress policies. However, when I follow the instructions I still am unable to access anything. io for in-depth information about using Istio. Changing Inject Policy in Default Policy Setting. To read more about Istio egress traffic control, see Control Egress Traffic Task. "Google, IBM and Lyft joined forces to create Istio from a desire to provide a reliable substrate for microservice development and maintenance, based on our common experiences building and operating massive scale microservices for internal and enterprise customers," the post said. You'll learn how Istio features such as traffic flow management, access policy. Whilst adopting Istio will give you immediate benefits, unlocking its full promise depends on having a well-designed microservice architecture. 1 provides significant reductions in CPU usage and latency over Istio 1. 0 Authorization Metric hètüS Denier Scrvicccontrol Rbacconfig "I-Ittpapispecstdio Envoyfiltèi' Logent ry Rule Dèdstinatlonrule Servicerole. The use of a gateway enables supplementary controls, such as using Kubernetes network policy, which can be configured to restrict all egress from the cluster except for traffic originating from the Egress Gateway. To enable such traffic for TCP, TCP egress rules must be created for the service mesh. Egress The includeIPRanges parameter can be used to prevent proxies from intercepting external requests. One of the four IP addresses, the one shown below, associated with the Forwarding rule, will be associated with the front-end of the load balancer. KubeCon 2018 was a great success! Over 2,000 attendees engaged with us on-site to learn how our comprehensive Cisco multicloud solutions can help them modernize their business applications for customer-centered experiences. Ambassador is an open source, Kubernetes-native API Gateway for microservices built on the Envoy Proxy. Here's the 30,000-foot view of how a sidecar container works with Kubernetes and Minishift: Once you've started your Minishift instance, you create a project for Istio (let's call it "istio-system"), and you install and start all of the Istio-related components. Istio intercepts all network communication between microservices, Istio includes the following capabilities: Automatic load balancing for HTTP, gRPC, WebSocket, and TCP traffic. Ingress rules. The Istio project uses the Envoy proxy and mutual TLS to secure communications between services deployed in a Kubernetes cluster. Today, IBM and Google announced the launch of Istio, an open cloud service that provides a way for developers to seamlessly connect, manage and secure networks of different microservices—regardless of platform, source or vendor. In this webinar we'll discuss the following traffic management topics. Forbes is a global media company, focusing on business, investing, technology, entrepreneurship, leadership, and lifestyle. Ambassador is an open source, Kubernetes-native API Gateway for microservices built on the Envoy Proxy. These keys and X. • Traffic routing management : Istio enables fine-grained control of microservices traffic behavior with rich routing rules, fault tolerance, and fault injection. But, before getting too far into the security features with the Istio service mesh, let's get some understanding of the high-level architecture of Istio and to understand the basics of authentication and authorization in the service mesh. Istio ingress gateway integrations operate at the edge of a service mesh, receiving incoming HTTP/TCP connections while configuring ports, protocols and virtual services. Istio's traffic management decouples traffic flow and infrastructure scaling allowing you to specify what rules to govern traffic rather than which specific pods should receive traffic. Configuring the external services. Egress was my best guess but it may be something else, however it is certainly istio related. Forcing all egress traffic through an egress gateway by default is borderline impossible. egress: Each NetworkPolicy may include a list of whitelist egress rules. I mentioned before, proxies are the data plane, how this technology actually does its actions. 我们看到Istio向每个Pod中插入一个sidecar container,这个就是前面说的envoy,只不过container名字为istio-proxy。 接下来,我们把那个external service启动起来: # nohup. More than 1 year has passed since last update. Istio is an open platform for providing a uniform way to integrate microservices, manage traffic flow across microservices, enforce policies and aggregate telemetry data. Essentially built a simplistic example A-B testing with Istio route-rules and tracing data 3. This chart bootstraps all istio components deployment on a Kubernetes cluster using the Helm package manager. In this blog post we are going to talk about istio and virtual machines on top of Kubernetes. Fine-grained control of traffic behavior with rich routing rules, retries, failovers, and fault injection. To illustrate we will use istioctl to set a timeout rule on calls to the httpbin service. In Istio it is called as control plan which consists of three key components Pilot, Mixer, Istio-Auth. Istio sends individual trace information automatically to Jaeger, the distributed tracing platform, even if your modern applications aren't aware of Jaeger at all. Istio and App Mesh both use Envoy as a data plane. The Istio project uses the Envoy proxy and mutual TLS to secure communications between services deployed in a Kubernetes cluster. [This is part ten of my ten-part Introduction to Istio. How is everyone handling deployments with Spinnaker to take use ISTIO egress/ingress rules. Egress gives you the power to bypass those IP tables, either based on Egress rules or for a range of IP addresses. Deny all traffic in the default namespace. Each rule allows traffic which matches both the to and ports sections. Above we can see the control/data plane API pods: Mixer, Pilot, and Ingress/Egress. Learn Launch Kubernetes Cluster, Deploy Istio, Istio Architecture, Deploy Sample Application, Bookinfo Architecture, Control Routing, Access Metrics, Visualise Cluster using Weave Scope, via free hands on training. To enable such traffic for TCP, TCP egress rules must be created for the service mesh. Envoy - Sidecar proxies per microservice to handle ingress/egress traffic between services in the cluster and from a service to external services. We’re excited to announce the general availability of Spring Cloud GCP 1. Istio Egress: Exit Through the Gift Shop This guide to using Istio with Red Hat OpenShift and Kubernetes shows you how to make microservices development easier, improving performance, tracing, and. High-level architecture. Forcing all egress traffic through an egress gateway by default is borderline impossible. Egress Rules. Istio Dashboard (using Grafana Istio add-on) showing microservice metrics (image source) In addition, because Istio controls all ingress and egress traffic to a service, it allows for complex microservice tracing to be captured and visualized with tools such as Zipkin. Whether you choose automatic or manual sidecar injection of the Istio Proxy, Istio's egress rules currently only support HTTP and HTTPS requests. Where Kubernetes/OpenShift itself gives you default round-robin load balancing behind its service construct, Istio allows you to introduce unique and finely grained routing rules among all services within the mesh. From the Istio website core functionality is defined as: Automatic load balancing for HTTP, gRPC, WebSocket, and TCP traffic. It is a completely open source service mesh that layers transparently onto existing distributed applications. As a developer, you don't want to. By default, Istio blocks all the traffic, TCP and HTTP, to the hosts outside the cluster. io for in-depth information about using Istio. The Voter API makes external calls to its backend services, using two alternate protocols, MongoDB Wire Protocol ( mongodb:// ) and RabbitMQ AMQP ( amqps:// ). I mentioned before, proxies are the data plane, how this technology actually does its actions. Istio ignores Kubernetes services, since Kubernetes services can only do round-robin load balancing. how to fix : Configuration not synced: first push for…. Istio, it's vision is to be an open platform to connect manage and secure services, both service to service and also messaging. You can create the Istio service mesh for your microservices application by adding a special sidecar proxy that intercepts all network calls between your microservices and subjects them to Istio checks and user-defined traffic rules. io istio-autogenerated-k8s-ingress -n istio-system Trafic load balancing is not working at layer seven. It does all this without requiring developers to make changes to application code by building on earlier work from IBM, Google and Lyft. Fine-grained control of traffic behavior with rich routing rules, fault tolerance, and fault injection. Traffic management: With a mesh network, it's fairly easy to regulate traffic between services using route rules. 8 and I want to finalize the use-cases before I submit an updated proposal. Istio An open platform to connect, manage, and secure microservices. You can use istioctl command for that: istioctl get egressrules -o yaml. In this video. It was launched by Google, IBM, and Lyft in 2016 and has been steadily becoming part of the cloud native toolbox. Steps to reproduce the bug. Istio is an open platform for providing a uniform way to integrate microservices, manage traffic flow across microservices, enforce policies and aggregate telemetry data. The goal of this abstraction layer is to provide an easy-to-consume API that can be implemented by many different service mesh implementations (e. The fact-checkers, whose work is more and more important for those who prefer facts over lies, police the line between fact and falsehood on a day-to-day basis, and do a great job. Today, my small contribution is to pass along a very good overview that reflects on one of Trump’s favorite overarching falsehoods. Namely: Trump describes an America in which everything was going down the tubes under  Obama, which is why we needed Trump to make America great again. And he claims that this project has come to fruition, with America setting records for prosperity under his leadership and guidance. “Obama bad; Trump good” is pretty much his analysis in all areas and measurement of U.S. activity, especially economically. Even if this were true, it would reflect poorly on Trump’s character, but it has the added problem of being false, a big lie made up of many small ones. Personally, I don’t assume that all economic measurements directly reflect the leadership of whoever occupies the Oval Office, nor am I smart enough to figure out what causes what in the economy. But the idea that presidents get the credit or the blame for the economy during their tenure is a political fact of life. Trump, in his adorable, immodest mendacity, not only claims credit for everything good that happens in the economy, but tells people, literally and specifically, that they have to vote for him even if they hate him, because without his guidance, their 401(k) accounts “will go down the tubes.” That would be offensive even if it were true, but it is utterly false. The stock market has been on a 10-year run of steady gains that began in 2009, the year Barack Obama was inaugurated. But why would anyone care about that? It’s only an unarguable, stubborn fact. Still, speaking of facts, there are so many measurements and indicators of how the economy is doing, that those not committed to an honest investigation can find evidence for whatever they want to believe. Trump and his most committed followers want to believe that everything was terrible under Barack Obama and great under Trump. That’s baloney. Anyone who believes that believes something false. And a series of charts and graphs published Monday in the Washington Post and explained by Economics Correspondent Heather Long provides the data that tells the tale. The details are complicated. Click through to the link above and you’ll learn much. But the overview is pretty simply this: The U.S. economy had a major meltdown in the last year of the George W. Bush presidency. Again, I’m not smart enough to know how much of this was Bush’s “fault.” But he had been in office for six years when the trouble started. So, if it’s ever reasonable to hold a president accountable for the performance of the economy, the timeline is bad for Bush. GDP growth went negative. Job growth fell sharply and then went negative. Median household income shrank. The Dow Jones Industrial Average dropped by more than 5,000 points! U.S. manufacturing output plunged, as did average home values, as did average hourly wages, as did measures of consumer confidence and most other indicators of economic health. (Backup for that is contained in the Post piece I linked to above.) Barack Obama inherited that mess of falling numbers, which continued during his first year in office, 2009, as he put in place policies designed to turn it around. By 2010, Obama’s second year, pretty much all of the negative numbers had turned positive. By the time Obama was up for reelection in 2012, all of them were headed in the right direction, which is certainly among the reasons voters gave him a second term by a solid (not landslide) margin. Basically, all of those good numbers continued throughout the second Obama term. The U.S. GDP, probably the single best measure of how the economy is doing, grew by 2.9 percent in 2015, which was Obama’s seventh year in office and was the best GDP growth number since before the crash of the late Bush years. GDP growth slowed to 1.6 percent in 2016, which may have been among the indicators that supported Trump’s campaign-year argument that everything was going to hell and only he could fix it. During the first year of Trump, GDP growth grew to 2.4 percent, which is decent but not great and anyway, a reasonable person would acknowledge that — to the degree that economic performance is to the credit or blame of the president — the performance in the first year of a new president is a mixture of the old and new policies. In Trump’s second year, 2018, the GDP grew 2.9 percent, equaling Obama’s best year, and so far in 2019, the growth rate has fallen to 2.1 percent, a mediocre number and a decline for which Trump presumably accepts no responsibility and blames either Nancy Pelosi, Ilhan Omar or, if he can swing it, Barack Obama. I suppose it’s natural for a president to want to take credit for everything good that happens on his (or someday her) watch, but not the blame for anything bad. Trump is more blatant about this than most. If we judge by his bad but remarkably steady approval ratings (today, according to the average maintained by 538.com, it’s 41.9 approval/ 53.7 disapproval) the pretty-good economy is not winning him new supporters, nor is his constant exaggeration of his accomplishments costing him many old ones). I already offered it above, but the full Washington Post workup of these numbers, and commentary/explanation by economics correspondent Heather Long, are here. On a related matter, if you care about what used to be called fiscal conservatism, which is the belief that federal debt and deficit matter, here’s a New York Times analysis, based on Congressional Budget Office data, suggesting that the annual budget deficit (that’s the amount the government borrows every year reflecting that amount by which federal spending exceeds revenues) which fell steadily during the Obama years, from a peak of $1.4 trillion at the beginning of the Obama administration, to $585 billion in 2016 (Obama’s last year in office), will be back up to $960 billion this fiscal year, and back over $1 trillion in 2020. (Here’s the New York Times piece detailing those numbers.) Trump is currently floating various tax cuts for the rich and the poor that will presumably worsen those projections, if passed. As the Times piece reported:
