Original GitHub issue: https://github.com/nektos/act/issues/2694

here is a workflow:

name: podman
on:
  push:
jobs:
  build-push:
    runs-on: ubuntu-latest
    steps:
      - run: |
          podman run quay.io/podman/hello

it works on github out of the box, podman is preinstalled

but it does not work with act, says podman: command not found, seems like catthehacker/ubuntu:act-latest image does not have podman preinstalled

if you install podman with apt, it still does not work

Installing all tools one by one into the medium image, makes it equivalent to catthehacker/ubuntu:full-latest .

I have never used podman within an act job container

if you install podman with apt, it still does not work

Give your docker container more permissions e.g. --container-options "--privileged"
