feat: install latest docker-mcp plugin in sbx template#3545

Signed-off-by: David Gageot <[email protected]>
All mcp-gateway releases are prereleases, so the GitHub /releases/latest redirect doesn't work; resolve the newest tag via the releases API instead. Assisted-By: Claude

The
docker-mcpCLI plugin needs to be available inside the sandbox template image so agents running in that environment can invoke MCP tooling out of the box. Without it, users hitting thesbxtemplate get a missing-plugin error the first time they try to use docker-mcp commands.The
templatestage of the Dockerfile now downloads and installsdocker-mcpinto~/.docker/cli-pluginsfor theagentuser. Because every release in thedocker/mcp-gatewayrepo is marked as a pre-release, the standardreleases/latest/downloadredirect returns a 404; the install script instead hits the GitHub releases API to resolve the newest tag, then fetches the architecture-matching tarball and extracts the binary directly into the plugins directory.Validated by building the
templatestage locally and confirmingdocker-mcp --versionreports v0.43.1.
