Difference between legacy and new-and-shiny

[WyriHaximus]

A few days ago I've started working on migrating my home cluster from legacy (summerwind) to new-and-shiny (github) runners hosted on kubernetes. One of the first things that came up is that the new images don't seem to have zip/unzip when using https://github.com/hashicorp/setup-terraform to set up terraform. Is there a resource available somewhere with the differences between summerwind and github runner images?

I'm seeing the exact same issue also trying to use setup-terraform.

[isatfg]

I think the image used for the runner scale set has less packages then the previous one. I got this working by adding the missing packages.

  - name: Install unzip and git
    run: sudo apt-get update && sudo apt-get install -y unzip git

[WyriHaximus]

Did you find anything else missing/different?

[isatfg]

One tip is to ensure you install the extra packages like git before the checkout task.

[WyriHaximus]

Anything else you found? Currently picking this up again and it feels a bit silly to have to install everything every single run

[jonwest]

We use the official runner images as a base and install the packages we require and publish our own runner images. Installing everything on every run definitely seems wasteful.

There is a difference between summerwind version runner image and ARC version runner image. You can check the difference through the Dockerfile.

[WyriHaximus]

RTFC isn't a really useful answer tbh. Sure I can see that unzip, jq, and at least git are missing in the ARC runner images. But I was kinda hoping for a table of differences somewhere.

I came up with this rough list using the following:

$ docker run -it --entrypoint /bin/sh summerwind/actions-runner -c "find ${PATH//:/ } -maxdepth 1 -executable | sort" > sw_binaries_sorted.txt

$ docker run -it --entrypoint /bin/sh ghcr.io/actions/actions-runner -c "find ${PATH//:/ } -maxdepth 1 -executable | sort" > gh_binaries_sorted.txt

# only show the binaries exclusively in summerwinds, but not in new runner image
$ comm -23 sw_binaries_sorted.txt gh_binaries_sorted.txt
