Sep 1, 2025

Sep 2025 focused on deployment reliability, automated maintenance, and improved observability. Implemented Tekton deployment reliability improvements including a retry for TektonConfig readiness and a fix to trust the system CA bundle via GIT_SSL_CAINFO, reducing flaky deployments and Git resolver errors. Enabled and configured Renovate to automate updates for Kyverno, Cert-Manager, Pipelines-as-Code, enterprise contract policies, and GitHub Actions, with cleanup and automation enhancements to reduce manual maintenance. Reorganized Kyverno bootstrap namespace policy for integration services and improved CI failure observability by enhancing logging and aligning integration test configurations. Added SLO monitoring for Smee services by introducing Grafana panels to reflect server/client availability and objectives, increasing visibility into service reliability. Stabilized test infrastructure and CI reliability by fixing a missing kubectl image in testrepo, updating testrepo SHA references in e2e-tests, and upgrading caching in infra-deployments to improve performance and consistency across environments.
