Update dockerfile to ubuntu:24.04

[joshua-clayton]

The Dockerfile has gotten pretty stale, and as a base for build images, leaves a lot of CVEs and vulnerabilities which are easily fixed by moving to a more recent base.

Update it to the most recent Ubuntu LTS.

I'm not sure if there is a more recent version of the dotnet image, but it seemed simpler to me to follow the installation instructions for action-runner in the Dockerfile.

Lastly, I added apt-get upgrade to the beginning of each apt command, which will keep the image up to date with the source image if it is rebuilt, and apt-get clean to the end of each apt command, which will keep the resultant layers smaller by removing apt download cache leftovers

Also, I don't know if your test suite will cover the Dockerfile, but I can confirm that I am using the above as a base for my self hosted runner. So its building and running with the github api. The only change I had to make to a downstream Dockerimage was to add "--break-system-packages" to the subsequent pip3 command in my local build image

Thanks for this Joshua - hopefully they update it soon

While waiting for review, I'm updating the dependencies to reflect releases since march. Once this is accepted, the internal github dependencies will be kept up to date by Github's own release process, but while I'm waiting for this to be merged, I need to keep my forked copy up to date.

@TingluoHuang I'd love to get this upgrade merged. Any objection to moving to Ubuntu 24.04?

[gthomson31]

Is there any plans to merge ?

Hey @joshua-clayton, I tried you suggested docker file, built it and uploaded to a my docker repo. but the runner shows: 'Waiting for docker' - for a long time. It can't communicate with the docker:dind from some reason. as far as I understand.

Did you encounter this? Maybe you can tell how to turn on better logging?

I used this yaml:

githubConfigUrl: "https://github.com/mycompany"
githubConfigSecret: github-token

runnerScaleSetName: "arc-runner-set"

controllerServiceAccount:
  namespace: arc-systems
  name: my-servoce-account-name

minRunners: 0
maxRunners: 30

runnerGroup: "default"

containerMode:
  type: "dind"

template:
  spec:
    containers:
      - name: runner
        image: my-personal-repo/actions-runner:ubuntu-24.04-v2
        imagePullPolicy: Always
