Previously CI tested a wide range (roughly Kubernetes 1.23 through 1.36); going forward only the actively supported Kubernetes range will be tested, freeing up CI resources. Developers who still need to validate against older Kubernetes versions can run the integration suite locally with kind, using the integ-suite-kind.sh script and checking test-infra commit history for the node image and config previously used in CI. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Why is Istio dropping CI testing for older Kubernetes versions starting with version 1.32? Istio's Test and Release Working Group is removing integration tests for Kubernetes versions that are end-of-life or nearing it, limiting CI to the actively supported Kubernetes range. Previously CI tested roughly Kubernetes 1.23 through 1.36; upstream Kubernetes only supports minor releases for about 14 months, and maintaining old node images consumed CI infrastructure and time. This change applies to the master branch, affecting Istio 1.32 and forward. _Track dependency support changes like this Istio and Kubernetes shift on daily.dev before they hit your CI pipeline._ ### How can I test Istio against an older, unsupported Kubernetes version now that CI no longer covers it? Run the integration suite locally using kind, the same tool Istio's CI relies on. Use the integ-suite-kind.sh script from the istio repository as the entry point, and check the test-infra repository's commit history to find the specific node image and kind-config values previously used for the Kubernetes version you need, replacing --node-image and --kind-config accordingly. _Engineers validating legacy Kubernetes setups can follow workflow changes like this on daily.dev._ ## Community discussion Top comments from developers on daily.dev. **@pdfopsdev** · 0 upvotes > makes sense given how fast the k8s api surface moves release to release. cert-manager and ingress-nginx trimmed their ci matrices the same way last year once maintaining older kind images cost more than the users asking for them. ## Similar posts on daily.dev -
