Install four MCP servers globally in the claude image:
@modelcontextprotocol/server-github → mcp-server-github
@yoda.digital/gitlab-mcp-server → gitlab-mcp-server
@aashari/mcp-server-atlassian-jira → mcp-atlassian-jira
@aashari/mcp-server-atlassian-confluence → mcp-atlassian-confluence
Wire them in managed-settings.json via mcpServers with env var
pass-through. Jira and Confluence share ATLASSIAN_* credentials.
Add api.github.com, .gitlab.com, .atlassian.net to the squid
allowlist. All credentials are optional — servers are skipped
if the relevant env vars are unset.
Replace node:20-slim/ubuntu:22.04 with node:20-alpine/alpine:3.21.
Switch package management from apt to apk (--no-cache, no cleanup layer).
Use Alpine addgroup/adduser in claude/Dockerfile. Update proxy to use
squid user (Alpine convention) and /var/cache/squid cache path.
Fix proxy/Dockerfile COPY path now that context is proxy/. Move
webui-entrypoint.sh into claude/ to match its build context. Fix
docker-compose.yml webui context to claude/, update proxy tmpfs path.
