6e38137ce4## Summary Bumps the node machine type from e2-small to e2-standard-2 to provide more CPU and memory headroom for the cluster. Also disables PodDisruptionBudgets (PDBs) for single-instance PostgreSQL clusters to prevent node upgrade operations from becoming blocked. ## Changes - Increase GKE node machine type from e2-small to e2-standard-2 - Set `enablePDB: false` for registry and Grafana PostgreSQL clusters ## Context The machine type increase addresses resource constraints causing deployment failures. The PDB change prevents a specific issue where GKE node upgrades get stuck when trying to drain nodes containing single-instance PostgreSQL pods. With `minAvailable: 1` PDBs, evicting the only database instance violates the availability requirement, blocking the drain operation indefinitely. Disabling PDBs for these development/staging single-instance databases allows node maintenance to proceed smoothly. For production deployments requiring high availability, the instances count should be increased to 3 with PDBs enabled. --------- Co-authored-by: Claude <noreply@anthropic.com>
