Drone Runner

For the runner, follow the same steps as for the server, but make sure you follow the instructions for the runners.

docker run --detach \
  --volume=/var/run/docker.sock:/var/run/docker.sock \
  --env=DRONE_RPC_PROTO=https \
  --env=DRONE_RPC_HOST=drone.company.com \
  --env=DRONE_RPC_SECRET=super-duper-secret \
  --env=DRONE_RUNNER_CAPACITY=2 \
  --env=DRONE_RUNNER_NAME=my-first-runner \
  --publish=3000:3000 \
  --restart=always \
  --name=runner \
  drone/drone-runner-docker:1

The instructions state that

  • the runner requires the file /var/run/docker.sock to be mounted
  • it listens on port 3000

Preparing dokku and the image​

dokku apps:create drone-runner

# env variables
dokku config:set drone-runner DRONE_RPC_SECRET=$(dokku config:get drone-server DRONE_RPC_SECRET)
dokku config:set drone-runner DRONE_RPC_PROTO=https
dokku config:set drone-runner DRONE_RPC_HOST=drone.lebalz.ch
dokku config:set drone-runner DRONE_RUNNER_CAPACITY=2
dokku config:set drone-runner DRONE_RUNNER_NAME=bolt

# mount the docker socket
dokku storage:mount drone-runner /var/run/docker.sock:/var/run/docker.sock

# change port mapping and set domain
dokku proxy:ports-add drone-runner http:3000:3000

# deploy
dokku git:from-image drone-runner drone/drone-runner-docker:latest

Update​

If you deployed :latest, then you would need to run

docker pull drone/drone-runner-docker:latest
dokku ps:rebuild drone-runner

To update to a specific version (e.g. 1.8.0) lookup the tags on https://hub.docker.com/r/drone/drone-runner-docker/tags and run on your dokku server:

dokku git:from-image drone-runner drone/drone-runner-docker:1.8.0

The application will be rebuilt automatically.
