Is your feature request related to a problem? Please describe.
I've moved to CRI-O, but you are requiring Docker.

I think you should support CRI-O too.

Hi @hupiper,

Could you please add here your env and actions performed? Also, if possible the error faced when you try to use it with CRI-O.

The problem is that you need Docker installed. If I generate a new tree for Ansible and run the build command:
[mdunnett@mdunnett image-uploader-operator]$ operator-sdk build image-upload-operator:v.1 INFO[0000] Building OCI image image-upload-operator:v.1 Error: failed to output build image image-upload-operator:v.1: (failed to exec []string{"docker", "build", "-f", "build/Dockerfile", "-t", "image-upload-operator:v.1", "."}: exec: "docker": executable file not found in $PATH)

If I run the build command pointing at Podman:
[mdunnett@mdunnett image-uploader-operator]$ operator-sdk build image-upload-operator:v.1 --image-builder podman INFO[0000] Building OCI image image-upload-operator:v.1 ERRO[0000] No subuid ranges found for user "mdunnett" in /etc/subuid Error: failed to output build image image-upload-operator:v.1: (failed to exec []string{"podman", "build", "-f", "build/Dockerfile", "-t", "image-upload-operator:v.1", "."}: exit status 1)

If I put mdunnett in subuid: sudo usermod --add-subuids 10000-65536 mdunnett

I get [mdunnett@mdunnett image-uploader-operator]$ operator-sdk build image-upload-operator:v.1 --image-builder podman INFO[0000] Building OCI image image-upload-operator:v.1 ERRO[0000] No subgid ranges found for group "mdunnett" in /etc/subgid Error: failed to output build image image-upload-operator:v.1: (failed to exec []string{"podman", "build", "-f", "build/Dockerfile", "-t", "image-upload-operator:v.1", "."}: exit status 1)

It just doesn't seem to work

This is on RHEL8

@hupiper for a short term have you considered installing podman-docker?

[hupiper]

Once I got the permissions figured out that I mentioned above, I started getting errors for XFS as an overlay being unsupported. It turns out Podman was not happy when I installed container-tools. I had to delete the storage.conf file for podman, then reinstall it - see http://chris.collins.is/2019/01/25/podman-overlay-is-not-supported-over-xfs/. My storage.conf file was in a different place than the location mentioned in the Chris Collins blog. Mine was in /home//.config/containers/storage.conf
