Description of problem:
After https://github.com/openshift/openshift-ansible/pull/8618 merged, it will install podman in node, this will cause to crio to use podman cni network, which conflict with  openshift-sdn, then all pods will keep ContainerCreating status and with error 'failed to find plugin "bridge" in path [/opt/cni/bin/ /opt/bridge/bin]'

Comment 1 Scott Dodson 2018-06-08 12:46:34 UTC

https://github.com/openshift/openshift-ansible/pull/8686 to remove podman from the install/upgrade, we added it prematurely

There's ongoing discussion in https://bugzilla.redhat.com/show_bug.cgi?id=1583591 as to whether or not we should add it and when.

Comment 3 DeShuai Ma 2018-06-11 02:10:12 UTC

The latest version is atomic-openshift-3.10.0-0.64.0.git.0.8285be6.el7.x86_64.rpm   
Wait for new build.

Comment 4 Scott Dodson 2018-06-12 12:52:25 UTC

In openshift-ansible-3.10.0-0.65.0 and later

Comment 5 DeShuai Ma 2018-06-13 07:53:35 UTC

Verified on openshift-ansible-3.10.0-0.66.0.git.79.68197f9.el7.noarch.rpm
