Istio

Istio addresses the challenges developers and operators face with a distributed or microservices architecture.

Istio extends Kubernetes to establish a programmable, application-aware network. Working with Kubernetes and traditional workloads, Istio brings standard, universal traffic management, telemetry, and security to complex deployments.

Istio was accepted to CNCF on September 30, 2022, at the Incubating maturity level and then moved to the Graduated maturity level on July 12, 2023.

Istio was moved to the adopt ring in the Thoughtworks Technology Radar in May 2020.

Troubleshooting

The istioctl configuration command line utility for service operators can be used to debug and diagnose the Istio mesh.

Ingress

Check the Istio ingress gateway routes:

istioctl proxy-config route -n istio-ingress <pod-name>
