The test was incorrectly using 'docker exec id -u' which always returns
the container's original user context, not the user that the entrypoint
switched to.
Key insights:
- docker exec creates NEW processes with the container's user context
- When container starts with --user root, docker exec runs as root
- The entrypoint correctly switches the MAIN process to nodejs user
- We need to check the actual n8n-mcp process, not docker exec sessions
Changes:
- Check the actual n8n-mcp process user via ps aux
- Parse the process owner from the ps output
- Added demonstration test showing docker exec vs main process users
- Added clear comments explaining this Docker behavior
This correctly verifies that the entrypoint switches the main application
process to the nodejs user for security, which is what actually matters.
This fixes the fundamental issue causing persistent test failures.
Root Cause:
- The entrypoint script's user switching was broken
- Used 'exec $*' which fails when no arguments provided
- Used 'printf %q' which doesn't exist in Alpine Linux
- User switching wasn't actually working properly
Fixes:
1. Added su-exec package to Dockerfile
- Proper tool for switching users in containers
- Handles signal propagation correctly
- No intermediate shell process
2. Rewrote user switching logic
- Uses su-exec with fallback to su
- Fixed command injection vulnerability in su fallback
- Properly handles case when no arguments provided
- Exports environment variables before switching
3. Added security improvements
- Restricted permissions on AUTH_TOKEN_FILE
- Added comments explaining su-exec benefits
This explains why tests kept failing - we were testing around a broken implementation rather than fixing the actual broken code.
The test 'should switch to nodejs user when running as root' was failing because:
- Alpine Linux's ps command shows numeric UIDs (1) instead of usernames (nodejs)
- Parsing ps output is unreliable across different environments
Fixed by:
- Using 'id -u' to check the numeric UID directly (expects 1001 for nodejs user)
- Adding functional test to verify write permissions to /app directory
- This approach is environment-agnostic and more reliable than parsing ps output
The test now properly verifies that the container switches from root to nodejs user.
Fixed 2 remaining test failures:
1. NODE_DB_PATH environment variable test:
- Issue: Null byte handling error in shell command
- Fix: Use existing getProcessEnv helper function that properly escapes null bytes
- This helper was already designed for reading /proc/*/environ files
2. User switching test:
- Issue: Test checked PID 1 (su process) instead of actual node process
- Fix: Find and check the node process owner, not the su wrapper
- When using --user root, entrypoint uses 'su' to switch to nodejs user
- The su process (PID 1) runs as root but spawns node as nodejs
Also increased timeouts to 3s for better CI stability.
Root cause analysis and fixes:
1. **MCP_MODE environment variable tests**
- Issue: Tests were checking env vars after exec process replacement
- Fix: Test actual HTTP server behavior instead of env vars
- Changed tests to verify health endpoint responds in HTTP mode
2. **NODE_DB_PATH configuration tests**
- Issue: Tests expected env var output but got initialization logs
- Fix: Check process environment via /proc/1/environ
- Added proper async handling for container startup
3. **Permission handling tests**
- Issue: BusyBox sleep syntax and timing race conditions
- Fix: Use detached containers with proper wait times
- Check permissions after entrypoint completes
4. **Implementation improvements**
- Export NODE_DB_PATH in entrypoint for visibility
- Preserve env vars when switching to nodejs user
- Add debug output option in n8n-mcp wrapper
- Handle NODE_DB_PATH case preservation in parse-config.js
5. **Test infrastructure**
- Created test-helpers.ts with proper async utilities
- Use health checks instead of arbitrary sleep times
- Test actual functionality rather than implementation details
These changes ensure tests verify the actual behavior (server running,
health endpoint responding) rather than checking internal implementation
details that aren't accessible after process replacement.
