Steps to Reproduce

I'm running the simple playbook from the README.

Expected Behavior

Playbook ran successfully.

Actual Behavior

It hangs here:

I run the command directly on the host:

# yum install  docker-ce docker-ce-cli containerd.io

(try to add '--allowerasing' to command line to replace conflicting packages or '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)

If I add --allowerasing to the yum command then it will successfully install these packages.

Since we're using the generic package command in the task, I don't see an easy way to resolve. Even if we used the yum command, it doesn't support adding options. It does support skip_broken, but I tried this and it doesn't work.

Hi @moonlight16! If I understand you correctly you are having a RHEL 8 machine with Podman already installed on, correct? Then you now want to install Docker CE using my role?

Cheers!

I have a similar effect, however, it's a Rocky Linux 9 VM ...

$ ansible --version
ansible 2.9.6

  executable location = /usr/bin/ansible
  python version = 3.8.10 (default, Jun 22 2022, 20:18:18) [GCC 9.4.0]

Ansible playbook:

- hosts: all
  vars:

    docker_compose: true
  roles:

Can you please run this command to see if you have installed podman in your system?

sudo dnf list --installed | grep podman
