Nov 1, 2024

November 2024 (openshift/microshift) delivered a focused set of reliability, performance, and operational improvements across provisioning, tests, and build/CI instrumentation. Key features include replacing TTY-dependent Podman registry selection with full_image, reorganizing container test scenarios into a dedicated directory, and introducing safeguards such as a source guard to prevent unsafe usage. Readiness and deployment reliability were enhanced with container IP polling to determine readiness, waits for core workloads, and an option to wait for a specific namespace. Storage and resource management were strengthened via per-container LVM volume groups, together with a series of testing enhancements (ostree booted system simulation with backups tests, and improved reuse of recovery paths). Operational instrumentation and performance improvements were achieved through boot image build time measurement, footprint-and-performance retry steps, and maintenance of build images, while ensuring visibility through prerun logs and attaching build logs to failed JUnit tests. Additional stability and hygiene work included repository hardening (disabling AWS RHUI repos and removing the RHUI client), enhanced error handling (e.g., ensure vg-manager exists before waiting for availability, and improved argument validation for --dont-save-failed with --auto-recovery).
