HowTo: Use Claude code with login inside docker compose

[ulope]

When running paperclip inside a docker compose stack (using the compose file from the /docker folder in the repo) I kept running into the issue that the claude_local adapter kept claiming that claude wasn't logged in (Not logged in).
Even tough running claude auth status confirmed successful login.

Turns out it's a permission issue.

The web process inside the container is run under user id 1000 but a plain docker compose exec ... uses root (uid 0).

So the solution is to:

docker compose exec --user 1000 server bash
claude login

That will ensure the claude config files are written with the correct user id.
