Install on Linux

This article explains how to install the Docker runner on Linux. The Docker runner is packaged as a minimal Docker image distributed on DockerHub, and is available for the following architectures:

  • amd64
  • arm
  • arm64

Step 1 - Download

Install Docker and pull the public image:

$ docker pull drone/drone-runner-docker:1

Step 2 - Configure

The Docker runner is configured using environment variables. This article references the below configuration options. See Configuration for a complete list of configuration options.

DRONE_RPC_HOST
provides the hostname (and optional port) of your Drone server. The runner connects to the server at the host address to receive pipelines for execution.
DRONE_RPC_PROTO
provides the protocol used to connect to your Drone server. The value must be either http or https.
DRONE_RPC_SECRET
provides the shared secret used to authenticate with your Drone server. This must match the secret defined in your Drone server configuration.

Step 3 - Install

The below command creates the a container and start the Docker runner. Remember to replace the environment variables below with your Drone server details.

$ docker run -d \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -e DRONE_RPC_PROTO=https \
  -e DRONE_RPC_HOST=drone.company.com \
  -e DRONE_RPC_SECRET=super-duper-secret \
  -e DRONE_RUNNER_CAPACITY=2 \
  -e DRONE_RUNNER_NAME=${HOSTNAME} \
  -p 3000:3000 \
  --restart always \
  --name runner \
  drone/drone-runner-docker:1

Step 4 - Verify

Use the docker logs command to view the logs and verify the runner successfully established a connection with the Drone server.

$ docker logs runner

INFO[0000] starting the server
INFO[0000] successfully pinged the remote server
