This page describes how to update the CircleCI self-hosted runner on CircleCI server installations.

Self-hosted runner for server compatibility

Refer to the server compatibility chart to find the runner version you need for your installation.

Upgrading self-hosted runner on server

Unlike CircleCI cloud, server does not automatically update the circleci-launch-agent, and requires manual intervention. The following sections detail how to upgrade self-hosted runners in your server installation across all environments.

Upgrading self-hosted runner in a containerized environment

This section details how to upgrade self-hosted runner in containerized environments: Kubernetes and Docker.

Upgrading self-hosted runner for Kubernetes

Upgrading self-hosted runner for Docker

  1. Stop any currently running self-hosted runner containers:

    docker stop <container-name>
  2. Remove the self-hosted runner containers:

    docker stop <container-name>; docker rm <container-name>;
  3. Start a new self-hosted runner Docker container:

    CIRCLECI_RESOURCE_CLASS=<resource-class> CIRCLECI_API_TOKEN=<runner-token> agent_version=<agent_version_for_server> docker run --env agent_version --env CIRCLECI_API_TOKEN --env CIRCLECI_RESOURCE_CLASS --name <container-name> <image-id-from-previous-step>

Upgrading self-hosted runner in a non-containerized environment

The process for manually updating the circleci-launch-agent binary can be broken down into three steps for non containerized environments. These steps are expanded upon in the sections below.

  1. Replace existing circleci-launch-agent binary with the new version.

  2. Stop currently running circleci-launch-agent processes.

  3. Start the new version of the circleci-launch-agent binary.

1. Replace the circleci-launch-agent-binary with the new version

Following the same process as in the Download the launch agent binary instructions, update the agent_version environment variable to the correct version from the Self-hosted runners for server compatibility chart.

export agent_version="<launch-agent-version>"

Then, following the platform specific installation instructions, replace the old binary with the newly updated version that was just downloaded.

2. Stop the currently running launch agent

The currently running circleci-launch-agent process will need to be halted before starting the newly updated binary. Platform-specific instructions for this are given below.

Stopping the launch agent on Linux

Run the following commands:

sudo systemctl stop circleci.service
sudo systemctl disable circleci.service
Stopping the launch agent on Mac

Run the following commands:

sudo launchctl unload '/Library/LaunchDaemons/com.circleci.runner.plist'
Stopping the launch agent on Windows

Run the following command:

Stop-ScheduledTask -TaskName "CircleCI Launch Agent"

3. Start the new self-hosted runner launch agent

Platform-specific instructions are given below.

Starting on Linux

Run the following commands:

sudo systemctl reload circleci.service
sudo systemctl enable circleci.service
sudo systemctl start circleci.service
Starting on Mac

Run the following command:

sudo launchctl load '/Library/LaunchDaemons/com.circleci.runner.plist'
Starting on Windows

Run the following commands:

Start-ScheduledTask -TaskName "CircleCI Launch Agent"
