This article explains how to install the exec runner on Linux. The exec runner is packaged in binary format and distributed as a Github release.

Step 1 - Download

Download and unpack the binary. You will need to modify the below commands to use the latest release.

Download for amd64 architectures:

curl -L https://github.com/drone-runners/drone-runner-exec/releases/download/${VERSION}/drone_runner_exec_linux_amd64.tar.gz | tar zx
sudo install -t /usr/local/bin drone-runner-exec

Download for i386 architectures:

curl -L https://github.com/drone-runners/drone-runner-exec/releases/download/${VERSION}/drone_runner_exec_linux_i386.tar.gz | tar zx
sudo install -t /usr/local/bin drone-runner-exec

Download for 32-bit arm:

curl -L https://github.com/drone-runners/drone-runner-exec/releases/download/${VERSION}/drone_runner_exec_linux_arm.tar.gz | tar zx
sudo install -t /usr/local/bin drone-runner-exec

Download for 64-bit arm:

https://github.com/drone-runners/drone-runner-exec/releases/download/${VERSION}/drone_runner_exec_linux_arm64.tar.gz | tar zx
sudo install -t /usr/local/bin drone-runner-exec

Step 2 - Configure

The exec runner is configured using an environment variable file. The environment file location is determined by the user running the process. If the user is root:

/etc/drone-runner-exec/config

If the user is not-root:

~/.drone-runner-exec/config

This file should use the syntax <variable>=value which sets the variable to the given value and # for comments. Please note this is not a bash file. Bash syntax and Bash expressions are not supported.

DRONE_RPC_PROTO=https
DRONE_RPC_HOST=drone.company.com
DRONE_RPC_SECRET=super-duper-secret

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 - Logging

The exec runner writes logs to a file on the host machine. The log file location must be configured before you start the service. The file location is determined by the user running the process. If the user is root:

DRONE_LOG_FILE=/var/log/drone-runner-exec/log.txt

If the user is non-root:

DRONE_LOG_FILE=.drone-runner-exec/log.txt

The log file directory must be created before you start the service:

mkdir /var/log/drone-runner-exec
mkdir .drone-runner-exec/

Step 4 - Install

Install and start the service.

drone-runner-exec service create
drone-runner-exec server start

Step 5 - Verify

Inspect the logs and verify the runner successfully established a connection with the Drone server. If the user is root:

$ cat /var/log/drone-runner-exec/log.txt

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

If the user is non-root:

$ cat ~/.drone-runner-exec/log.txt

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