This is an actions runner docker image for use with Actions Runner Controller. The Dockerfile is based on the example in this documentation. However, rather than using mcr.microsoft.com/dotnet/runtime-deps:6.0 as the base image, I use ubuntu:24.04 as the base and install a few tools needed in my workflows.

The packages of this repo correspond to the releases of the actions runner.

This image pre-populates the GitHub Actions tool cache at /opt/hostedtoolcache.

• node: the latest 3 LTS major lines (latest patch version of each), stored at /opt/hostedtoolcache/node/<version>/<arch>
• uv: the latest release at image build time, stored at /opt/hostedtoolcache/uv/<version>/<arch>

The following environment variables are set for compatibility with setup actions:

• AGENT_TOOLSDIRECTORY=/opt/hostedtoolcache
• RUNNER_TOOL_CACHE=/opt/hostedtoolcache
