summary
Migrates multiple Spanish ministries from a manual, single-branch, ticket-driven deployment model to GitOps using Argo CD and Kubernetes, replacing latest-image chaos with build IDs and semantic versioning, moving manifests from Kustomize overlays to per-environment Helm charts, adding CI checks and automated image/tag injection, implementing DB dump/preview blue‑green flows with manual approval and automatic rollback, and adding runtime and metrics with Falco and Prometheus/Grafana; deployment automation reduces ticketing and gives dev teams independence while resource limits and monitoring prove essential.
