# CryptPad — Notes

## Config directory requires emptyDir + initContainer

CryptPad's `/cryptpad/config/` directory is in the image overlay filesystem and is not writable
by the container process even when running as root.

**Fix**: mount an `emptyDir` at `/cryptpad/config` and use an initContainer to pre-seed
`config.example.js` from the image into the emptyDir:

```yaml
initContainers:
  - name: seed-config
    image: cryptpad/cryptpad:version-X.Y.Z
    command: [sh, -c, "cp /cryptpad/config/config.example.js /config-dest/config.example.js"]
    volumeMounts:
      - name: cryptpad-config
        mountPath: /config-dest
volumes:
  - name: cryptpad-config
    emptyDir: {}
```

Set `CPAD_CONF=/cryptpad/config/config.js` — the startup script copies `config.example.js` to
`config.js` on first run if `config.js` doesn't exist.
