3 Commits • 1 Features

May 1, 2026

May 2026 monthly summary for the redhat-appstudio-qe/infra-deployments repo focused on Konflux operator deployment overlays and CI/testing enhancements. Delivered three key overlays to streamline operator-based deployment and end-to-end testing: (1) development-operator overlay to deploy the Konflux operator, (2) CI overlay to enable Konflux ring deployments in CI, and (3) a placeholder OpenShift CI entrypoint to trigger end-to-end tests. These changes establish the operator-driven path for Konflux deployment, enable ring-style promotion workflows, and provide a foundation for broader OpenShift CI validations. Tech stack and skills demonstrated include overlay-based deployment configurations, CI overlay integration, and OpenShift CI readiness, delivering tangible business value by improving release reliability and test coverage.

Dec 1, 2025

December 2025 monthly summary for konflux-ci/konflux-ci. The month delivered a more reliable, observable Konflux operator with streamlined CI/CD, while expanding test coverage and automating manifest workflows to reduce manual maintenance. Key features delivered: - Konflux operator bootstrap and CEL validation (KFLUXVNGD-564): bootstrap the operator scaffold and enforce singleton CR naming via CEL validation, enabling safe, predictable deployments. - Install results using operator (KONFLUX-11249): migrate installation of Tekton results to the Tekton operator, removing manual kustomize-based installs for reliability and consistency. - Automate upstream manifests updates and per-component updates: implement automated upstream manifests workflow (KFLUXVNGD-584) and update manifests per component to enable parallel, componentized PRs and reduce drift. - Operator E2E tests added and stabilized: add operator-focused end-to-end tests (KFLUXVNGD-594) to validate operator deployment in CI and ensure CI stability. - Konflux-info added to operator: deploy konflux-info with the operator to improve visibility (KFLUXVNGD-597). Major bugs fixed: - Run kube-linter on generated operator manifests: ensure quality checks run directly on pre-generated files. - E2E test workflow fixes for operator deployment: address PR-target workflow timing to ensure tests run reliably. - Manifest/update workflow fixes (app token and bot approvals): switch to app token for PRs and issues, and ensure bot approvals for e2e tests. - Renovate and CRD maintenance: fix renovate configs for kind updates, ignore operator manifests, and regenerate ungenerated CRDs to keep in-sync with vendored/upstream state. Overall impact and accomplishments: - Improved deployment reliability by moving installations to the Tekton operator and enforcing CR naming at the schema level. - Reduced manual toil through automated upstream manifests and per-component updates, speeding releases and decreasing drift. - Strengthened CI/CD reliability with operator E2E tests, workflow context enhancements, and quality checks on manifests. - Enhanced observability and governance with konflux-info and improved workflow controls. Technologies/skills demonstrated: - Operator development with operator-sdk and CEL validation - Tekton-based installation flows, kustomize, and manifest management - CI/CD automation with GitHub Actions and per-component PRs - E2E testing and test path filtering improvements - Observability via zusätzliche CRDs (konflux-info) and workflow governance
