Nov 1, 2024Monthly summary for 2024-11 (repo: rackerlabs/genestack). Key features delivered: Prometheus install script enhancements with dynamic inclusion of Helm values files (validating existence of override, alert rules, and alertmanager config in base/config dirs), release-name standardized to kube-prometheus-stack, and corresponding docs updates. Helm chart installation automation script and meta-configuration introduced to streamline deployments and reduce boilerplate. Migration from Kustomize to Helm for Prometheus exporters with updated CI/CD workflows and docs reflecting the bin/install-chart.sh workflow. Major bugs fixed: install script now skips missing values files; release-name alignment with previous convention; doc corrections to post-checking commands to reflect the release name. Overall impact: automation reduces boilerplate, accelerates reliable deployments, and improves consistency across environments, enabling faster observability readiness and safer upgrades. Technologies/skills demonstrated: Helm, Kustomize to Helm migration, GitHub Actions CI/CD, scripting, automation, documentation, and release management.
