February 2025 monthly summary focusing on business impact and technical achievements. Highlights by repo: - canonical/haproxy-operator: - Documentation: HAProxy Operator Index and Scope — added a docs index clarifying operator purpose, Juju version compatibility, key features (TLS, monitoring, high-availability), and scope (IAAS/VM only, not Kubernetes). Commit 33ffd4a0f86fbe20f4d0757aaeaaeac9b61361cb. - HAProxy Monitoring: Loki alerts — introduced Loki-based alerts for critical (hacluster_no_quorum, hacluster_node_lost) and warning (hacluster_vip_started, hacluster_vip_stopped) events with licensing tracking integration. Commit 5fd02f4783be4476cf64878585be1086141a9ce7. - IPv6 and TLS readiness — binds IPv4/IPv6 and refactors TLS readiness checks (remove block_on_tls_not_ready; add _ensure_tls) for robustness. Commit 324b22f30fc9fcce5ac277c533c26259fb494442. - canonical/synapse-operator: - MAS error handling improvements and documentation — wraps pebble.ExecError with custom exceptions; updates docs and ensures charm blocks on MAS-CLI errors, improving robustness and user-facing error reporting. Commit 747c605df626f6bb829cfd6baf99bd2f2fda0f53. - Code ownership governance update for requirements.txt — updates CODEOWNERS to assign ownership of requirements.txt to @canonical/is-charms for better ownership and review processes. Commit 230f2c04c70c97ae61138f123fb83f3875cec630. Overall impact: - Strengthened reliability, observability, and governance; improved network compatibility and security readiness; clarified ownership and faster issue resolution.
