Have you played with podman? The team supporting containers in RHEL is moving away from Docker to other container tools. Podman, Buildah for RHEL7 container workload, and CRI-O for Kubernetes/OpenShift

Did docker not update the code after that?

[rhatdan]

We are locked into an older version of Docker for kubernetes/openshift support.

@rhatdan We found that many bugs fixed on moby were not fixed on projectatomic / docker. Are you planning to no longer maintain and update the docker-1.13.1-rhel branch?

[free2k]

@rhatdan If we replace docker with podman, does Kubernetes need to change?

[rhatdan]

Yes we have moved on from Docker to Podman in Fedora as well as RHEL/Centos.
Kubernetes should be using CRI-O instead of Docker. Podman is a command line tool, not a CRI for use with the kublet.
