…ra containers, volumes) The gateway deployment cannot currently host sidecars (e.g. a cloud-sql-proxy for external Postgres), extra init containers (e.g. a secrets bootstrapper), extra volumes/mounts, or an entrypoint wrapper. Add the standard optional extension values, all default-empty: - mcpContextForge.command / args: override the container entrypoint - mcpContextForge.extraInitContainers / extraContainers - mcpContextForge.extraVolumes / extraVolumeMounts With default values the rendered output is byte-identical to the current chart.

The mcp-stack gateway deployment currently offers no way to add sidecar containers, extra init containers, extra volumes/mounts, or to wrap the container entrypoint. Running the gateway against managed infrastructure often needs exactly that — e.g. a
cloud-sql-proxysidecar for an external Postgres, or an init container that materializes secrets from a CSI mount before the gateway starts.This adds the standard optional extension values under
mcpContextForge, all default-empty:command/args: override the gateway container entrypointextraInitContainers/extraContainersextraVolumes/extraVolumeMountsBackwards compatible: with default values the rendered output is byte-identical to the current chart (
