Is it supported to usr Docker conatiner runtime instead of CRI-O on OCP 4.x cluster?

Solution Verified - Updated -

Issue

  • In our environment, some of the images expect a docker container runtime to run and were running fine in ocp3 but fails in ocp4.
  • One solution would be to have part oc the nodes running with the docker runtime instead of cri-o. Do you know if that's possible?

Environment

  • Red Hat OpenShift Container Platform 4.x
