Jul 1, 2025In 2025-07, major/cloud-init delivered three core outcomes: feature enablement for network configuration with Netplan, reliability improvements in the CI pipeline, and improved documentation accuracy. Netplan MTU Stripping Feature adds STRIP_INVALID_MTU to strip invalid MTU values (0) from v2 netplan configurations, ensuring backward compatibility and smoother deployments. Documentation Accuracy Improvements fixes content-type mapping for Jinja templates and clarifies #include usage across user-data formats. CI/Test Infrastructure Stabilization updates CI workflow to test against currently supported Ubuntu releases and downgrades LXD to a stable channel to resolve integration test failures. These efforts reduce deployment risk, improve interoperability with downstream users, and increase CI reliability, accelerating iteration and release cycles. Technologies/skills demonstrated include Netplan configuration handling, Jinja templating, documentation discipline, CI/CD automation, and Linux container testing with LXD.

Nov 1, 2024November 2024 (2024-11) focused on stabilizing and expanding the major/cloud-init release process for PLUCKY, strengthening CI reliability, and improving test maintainability. Deliverables include a PLUCKY rollout with grub_dpkg marked inactive for PLUCKY and future releases, CI/test expectations aligned to the new release, and tests updated to reflect grub_dpkg removal. Critical CI packaging tests workflow fix and removal of a broken docs option from the cloud-init schema reduced release risk and failure modes. The test suite was reorganized for default configurations to improve clarity, and test stability improvements were implemented for FTP and apt-get tests. These efforts collectively reduce release risk, shorten cycle times, and increase test determinism and maintainability.
