March 2025 monthly summary for timescale/cloud-actions: Focused on reliability and credential-handling in deployment workflows. Delivered a critical fix to the SC CLI installation flow by correcting an input variable name typo and relocating AWS credentials environment variable configuration to the correct task, ensuring credentials are passed to the installation script and preventing installation failures. The change was validated through the commit f06223ae8c61ed5228baa4f3e6fde01f14bbddc4 ("fix sc install action (#58)").

February 2025: Delivered PostgreSQL Version Management for Docker Deployments in timescale/timescaledb-docker-ha. Implemented centralized version control for PostgreSQL in Docker builds with a new versions.yaml and a supporting script to streamline updates across the build pipeline. Dockerfiles and apt sources were updated to include archive repositories, and builds were aligned to reflect the latest minor PostgreSQL releases (e.g., 17.4). This work improves build determinism, repeatability, and maintenance across deployment environments, reducing drift and simplifying upgrades.
