You should have NO virtualservice nor destinationrule (in tutorial namespace) kubectl get virtualservice kubectl get destinationrule if so run: ./scripts/clean.sh tutorial Make sure you are in the main directory of "istio-tutorial". Configuration affecting traffic routing. Here are a few terms useful to define in the context of traffic routing. Service a unit of application behavior bound to a unique name in a service registry. Circuit Breaker trips for Http errors 502, 503, and 504 but not in the case of Http 500. Describe the bug I deploy the bookinfo sample app shortly (between 30-60 seconds) after deploying Istio. I receive the following error, even though the associated CRDs have been created and show type: Established and status: "True": $ ku... A VirtualService must be bound to the gateway and must have one or more hosts that match the hosts specified in a server. The match could be an exact match or a suffix match with the server’s hosts. For example, if the server’s hosts specifies *.example.com, a VirtualService with hosts dev.example.com or prod.example.com will match. Jan 23, 2020 · Blog Post. Istio 1.4 improves user experience and simplifies managing clusters. Istio 1.4 includes a new Istio operator, new Istio controller, new `v1beta1` authorization policy, automatic mutual Transport Layer Security (TLS) support, and updates to `istioctl`. 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. For example, the following simple Gateway configures a load balancer to allow external https traffic for host bookinfo.com into the mesh: I'm still experimenting with Istio in a dev cluster, along with a couple of other people. We have a sample virtualservice, deployment, and destinationrule, and requests to the specified uri are go...

Although the default Istio behavior conveniently sends traffic from any source to all versions of a destination service without any rules being set, creating a VirtualService with a default route for every service, right from the start, is generally considered a best practice in Istio. Feb 11, 2020 · Although Istio can be configured to support Kubernetes Ingress Resources, a better approach would be to use Istio’s custom resources (Gateway, VirtualService). That way you can use Istio features for more than internal services, including ingresses, giving you access to way more features than you’d have with just Kubernetes’ Ingress ... A Gateway allows Istio features such as monitoring and route rules to be applied to traffic entering the cluster. This task describes how to configure Istio to expose a service outside of the service mesh using an Istio Gateway. Before you begin. Setup Istio by following the instructions in the Installation guide. I'm using redis with k8s 1.15.0, istio 1.4.3, it works well inside the network. However when I tryed to use the istio gateway and sidecar to expose it to outside network, it failed. Then I removed the istio sidecar and just started the redis server in k8s, it worked. After searching I added DestinationRule to the config, but it didn't help. Using the built-in ingress gateway (along with some VirtualService and DestinationRule resources) this post showed how you can easily leverage Istio’s traffic management for cluster-external ingress traffic and cluster-internal service-to-service traffic. This technique is a great example of an incremental approach to adopting Istio, and can ...

Istio applies traffic rules for services after the routing has happened. These can include different settings such as connection pooling, circuit breakers, load balancing, detection, etc. Istio can define the same rules for all services under a host or different rules for different versions of the service. Aug 06, 2020 · Maistra is an opinionated distribution of Istio designed to work with Openshift. It combines Kiali, Jaeger, and Prometheus into a platform managed by the operator. The current version of OpenShift Service Mesh is 1.1.5. According to the documentation, this version of the service mesh supports Istio 1.4.8. Is your istio-galley certificate still valid? Edit: with a clean install of istio 1.3.0, I'm not seeing the same issues that you are seeing. I can launch a virtualservice / deployment just fine. Edit 2: Looks like #17718 is more recent and was fixed by #17995, which is not in 1.3.0, but would likely be in 1.3.6 or 1.4.x $ kubectl logs -n istio-system $(kubectl get pod -l istio=pilot -n istio-system -o jsonpath={.items..metadata.name}) -c discovery | grep "non unique port" 2018-09-14T19:02:31.916960Z info model skipping server on gateway mygateway2 port https.443.HTTPS: non unique port name for HTTPS port Istio service mesh is a sidecar container implementation of the features and functions needed when creating and managing microservices. Monitoring, tracing, circuit breakers, routing, load balancing, fault injection, retries, timeouts, mirroring, access control, rate limiting, and more, are all a part of this. Architecture for Istio 1.4.x and earlier. Picture Source. Notice in the above diagram that each pod in the cluster has both a service and a proxy. 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.

Envoy Issue 7728) about regular expressions (or regex) matching that crashes Envoy with very large URIs.After investigation, the Istio team has found that this issue could be leveraged for a DoS attack in Istio, if users are employing regular expressions in some of the Istio APIs: JWT, VirtualService, HTTPAPISpecBinding, QuotaSpecBinding.
