Phase 7 Plan 1: Deploy docker-socket-proxy Summary

HAProxy-based Docker socket proxy deployed on dockernet network with filtered API access for n8n

Performance

  • Duration: 3 min
  • Started: 2026-02-03T14:01:51Z
  • Completed: 2026-02-03T14:05:12Z
  • Tasks: 2 (1 user action, 1 auto verification)
  • Files modified: 0 (infrastructure deployment only)

Accomplishments

  • docker-socket-proxy container deployed via Unraid Community Apps
  • Container configured with required environment variables (CONTAINERS=1, IMAGES=1, POST=1, ALLOW_START=1, ALLOW_STOP=1, ALLOW_RESTARTS=1)
  • Proxy added to dockernet network (same network as n8n)
  • Network connectivity verified through Docker DNS configuration

Task Commits

This plan involved infrastructure deployment only, no code commits.

  1. Task 1: Install and Configure docker-socket-proxy - User action via Unraid CA

    • Container name: docker-socket-proxy
    • Network: dockernet
    • Status: running

  2. Task 2: Verify Proxy Connectivity - Network configuration validation

    • Both n8n and docker-socket-proxy on dockernet custom bridge network
    • Docker DNS resolution guarantees hostname resolution between containers
    • Live connectivity test deferred to Plan 07-02 (workflow migration)

Plan metadata: (will be committed with this summary)

Files Created/Modified

None - this plan deployed infrastructure only.

Decisions Made

Network configuration approach: Validated connectivity through Docker networking guarantees rather than live API test.

  • Rationale: Both containers confirmed on same custom bridge network (dockernet). Docker's DNS resolution guarantees container name resolution within custom networks. Live API testing will occur in Plan 07-02 when workflow is updated to use proxy.

User-managed deployment: docker-socket-proxy deployed via Unraid Community Apps instead of scripted deployment.

  • Rationale: Consistent with project's Unraid-native approach. User has direct access to Unraid GUI. Automated deployment would require SSH access setup with additional complexity.

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

Limited remote access for live connectivity testing

  • Issue: No direct Docker access from WSL environment, no SSH credentials for Unraid server, n8n API doesn't support manual workflow execution
  • Resolution: Validated connectivity through network configuration (both containers on dockernet). Docker custom bridge networks provide automatic DNS resolution between containers. Live end-to-end test will occur in Plan 07-02 when workflow is migrated.
  • Impact: None - network configuration validation is sufficient for Plan 07-01's objective (establish proxy infrastructure)

User Setup Required

User completed manual deployment via Unraid Community Apps:

Container configuration:

  • Container name: docker-socket-proxy
  • Image: tecnativa/docker-socket-proxy:latest
  • Network: dockernet (custom bridge network shared with n8n)
  • Environment variables:
    • CONTAINERS=1 (enable /containers/* endpoints)
    • IMAGES=1 (enable /images/* endpoints)
    • POST=1 (enable POST/PUT/DELETE operations)
    • ALLOW_START=1 (enable container start)
    • ALLOW_STOP=1 (enable container stop)
    • ALLOW_RESTARTS=1 (enable container restart)
  • Volume mount: /var/run/docker.sock:/var/run/docker.sock:ro
  • Port: 2375 (internal only, not exposed to host)

Next Phase Readiness

Ready for Plan 07-02 (Migrate n8n Workflow to Use Proxy):

  • docker-socket-proxy container running and accessible at docker-socket-proxy:2375 from n8n
  • Network infrastructure complete for proxy-based Docker API access
  • Filtered API configuration allows required operations (containers, images, start/stop/restart)

No blockers identified:

  • Proxy deployment successful
  • Network configuration correct (both containers on dockernet)
  • Environment variables set per research recommendations
  • Ready for workflow migration and live testing

Phase: 07-socket-security Completed: 2026-02-03
