# Drone CI

- Registry cannot be removed if it has https:// in its name #2341

https://github.com/drone/drone/issues/2341

https://discourse.drone.io/t/unable-to-delete-registry-from-repository/943

## Limitations

- Drone DIND would always reuse cached docker images which could lead to the image leak across the private repos;

- Drone runs plugins/drone in privileged mode despite the repo does not have Trusted: true nor privileged: true [ref](https://github.com/drone-plugins/drone-docker/issues/170)

- Builds history cannot be removed (could lead to info leaks)

## Troubleshooting

- Set the Registry creds in your Drone repo

```
Error response from daemon: Get https://docker.nixaid.com:5010/v2/plugins/docker/manifests/17.12: no basic auth credentials
```

- Make sure plugins/drone is running in a privileged mode, by passing DRONE_ESCALATE=custom-docker-registry.com:5010/plugins/docker to the Drone server installation.
