Month: 2026-03 — Mirrord monthly summary for metalbear-co/mirrord Highlights: - Key features delivered: Implemented Init Container Targeting in Kubernetes Pods, enabling mirrord to intercept and manage init containers. Updated runtime data handling to include init container statuses and added end-to-end tests to ensure correct behavior across pod startup sequences. Updated changelog accordingly. - Major bugs fixed: Stabilized test suite around init-container scenarios; fixed test reliability issues (removing cfg_attr usage in tests) and made status.initContainerStatuses optional to improve resilience in real-world pods. - Overall impact and accomplishments: Enables more realistic testing and deployment scenarios for init containers, reducing rollout risk when mirroring pods with init steps. Strengthens confidence in pod startup behavior under mirroring, and provides a foundation for broader container coordination features in future releases. - Technologies/skills demonstrated: Kubernetes pod lifecycle awareness, init-container targeting, end-to-end testing, runtime data handling, changelog and test maintenance, cross-team collaboration. Note: All changes tied to feature work include the commit c3d0080fec24bac431dc97d52f9eb67f3a5201a5 (target init containers, e2e tests, test refinements, and status data adjustments).
