| Debugging the Local Docker Image | Developer guide for attaching VS Code debuggers to Charon running in Docker containers. |
Debugging the Local Docker Image
Use the charon:local image as the source of truth and attach VS Code debuggers directly to the running container. Backwards-compatibility: cpmp:local still works (fallback).
1. Enable the debugger
The image now ships with the Delve debugger. When you start the container, set CHARON_DEBUG=1 (and optionally CHARON_DEBUG_PORT) to enable Delve. For backward compatibility you may still use CPMP_DEBUG/CPMP_DEBUG_PORT.
docker run --rm -it \
--name charon-debug \
-p 8080:8080 \
-p 2345:2345 \
-e CHARON_ENV=development \
-e CHARON_DEBUG=1 \
charon:local
Delve will listen on localhost:2345, while the UI remains available at http://localhost:8080.
2. Attach VS Code
- Use the Attach to Charon backend configuration in
.vscode/launch.jsonto connect the Go debugger to Delve. - Use the Open Charon frontend configuration to launch Chrome against the management UI.
These launch configurations assume the ports above are exposed. If you need a different port, set CHARON_DEBUG_PORT (or CPMP_DEBUG_PORT for backward compatibility) when running the container and update the Go configuration's port field accordingly.
