Hello @mikeharder, We'll consider your suggestion to add pwsh to the Slim image. However, adding many apps will turn the Slim image into a standard image, which is not the goal of creating a Slim image.

@Alexey-Ayupov: In that case, could you consider offering both the ubuntu-slim and ubuntu-24.04 images on the 1 vCPU runners? I'd like to use a 1 vCPU runner, but still have all the same apps as the standard runners.

I fully agree on this request. PowerShell (without any extra modules of course for size) would be a great addition to the slim runner.

Some of us (a lot?) are a lot better at shell pwsh than bash. A lot of our existing action code runs with pwsh as shell and with it on the slim image we can avoid porting it.

Thanks for the requests, we chatted and agree. I'll be adding Powershell in the next image update to be rolled out early next week.

Great news - thank you!

I pushed this image update to Monday. The image update is active in our test environments and, assuming everything looks good, I'll get it rolled out to production on Monday.
