Gloo Mesh now extends this innovation to multi-cluster environments, delivering unmatched reliability, simplicity, and scale. The idea behind canary deployment (or rollout) is to introduce a new version of a service by first testing it using a small percentage of user traffic, and then if all goes well, increase, possibly gradually in increments, the percentage while simultaneously phasing The Istio control plane can be one version ahead of the data plane. So far we just added alternate DNS names to the certificate and updated the certificate into the tls-rancher-ingress secret. 24. as api1. Adding to this response the header Strict-Transport-Security to inform browsers that the site should only be accessed using HTTPS See: https 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 How could I write rule for my VirtuelService such that traffic with url "/v1/myservice" and header "x-client-id: test" should route to "my-service-v2-dev", otherwise traffic with url "/v1/myservice" and with any header should route to "my-service-dev" Below is my code which is not working as expected and all traffic is going to "my-service-v2-dev".

HSTS is useful for speeding up interactions with websites. In an Istio mesh, it is possible to use eBPF to replace iptables rules, and accelerate the data plane by shortening the data path. This feature Istio makes this easy with a feature called “Auto mTLS”. The private key, server certificate, and the root certificate required by mutual TLS are configured using a file mount based approach. This DNS alias has the same form as the DNS entries for local services, namely <service name>. DNS aliases provide location transparency for your workloads: the workloads can call local and external services in Follow this guide to install, configure, and use an Istio mesh with the Pod Security admission controller () enforcing the baseline policy on namespaces in the mesh.

Traffic mirroring, also called shadowing, is a powerful concept that allows feature teams to bring changes to production with as little risk as possible. Istio is installed in its own istio-system namespace and can manage services from all other namespaces. In my case, I took configuration for Pod metrics from this example and modified Istio's Prometheus configuration only for Pods: kubectl edit configmap -n istio-system In our previous blog post about the Istio service mesh, we provided an overview of Istio’s features and capabilities and why you may (and sometimes may not, at least not yet) want to use it as a service mesh in your Kubernetes HTTP Strict-Transport-Security (HSTS): Inform browser that the site should only be accessed using HTTPS, and that any future attempts to access it using HTTP should automatically be converted to HTTPS. Install curl. Traffic Management. The hierarchy of Telemetry configuration is as follows: Workload-specific configuration; Namespace-specific configuration; Root namespace configuration This guide walks you through the process of installing an external control plane and then connecting one or more remote clusters to it. Stack Overflow for Teams Where developers & technologists share private knowledge with coworkers; Advertising & Talent Reach devs & technologists worldwide about your product, service or employer brand; OverflowAI GenAI features for Teams; OverflowAPI Train & fine-tune LLMs; Labs The future of collective knowledge sharing; About the company What is Istio? Istio extends Kubernetes to establish a programmable, application-aware network. This task shows you how Istio configures a variety of ports that may be locked down to improve security. If you are completely new to Istio and Issue The requirement is to set HSTS headers mentioned in Istio Enabled OpenShift routes Environment Red Hat OpenShift Container Platform 4. I need to try the TCP protocol for the virtual service, I'll try that to see if that's better than TLS Passthrough. If desired, these can be closed: Port 8080 exposes the debug interface, which offers read access to a variety of details about the clusters state. x, 23. Below explains various properties mutual TLS provides for the security posture of Istio. Once enabled, the discoverability of service endpoints is determined by client location and whether the service has been exported. You set the ratings to be one star to provide yourself with a visual clue that your external database is indeed being used. <namespace name>. io/rev NAME READY STATUS RESTARTS AGE REV istiod-5649c48ddc-dlkh8 1/1 Running 0 71m default istiod-canary-9cc9fd96f-jpc7n 1/1 Running 0 34m canary Follow the steps here to test or migrate existing workloads to use the canary control This is just deploying the demo app, it’s not adding any Istio components. Working with both Kubernetes and traditional workloads, Istio brings standard, universal traffic management, telemetry, and security to SPIRE is a production-ready implementation of the SPIFFE specification that performs node and workload attestation in order to securely issue cryptographic identities to workloads running in heterogeneous environments.
