Broken by this PR, assigning to release team. https://github.com/openshift/origin/pull/13642
https://github.com/openshift/origin/pull/14350 has some discussion on the topic and proposed solution
Changing sev to urgent - openshift-ansible installs are currently broken.
(In reply to Mike Fiedler from comment #3) > Changing sev to urgent - openshift-ansible installs are currently broken. When you say installs are broken, how are they broken, is there an error? If the install is failing because of this I'll pick this up and fix it. If it's not actually preventing successful installation I'm going to leave this with the release team as they initiated the breaking change.

Still reproducible on atomic-openshift-node-3.6.94-1.git.0.ba4aad2.el7.x86_64
Are there any workarounds for this?
The fix will be included in the next OCP build which should land today. As a workaround, use the full path to /usr/bin/docker.
Or rm /usr/local/bin/docker
Should be fixed in v3.6.99-1
