OpenShift pods won't deploy due to error: failed to find plugin "bridge" in path [/opt/bridge/bin /opt/cni/bin]
Issue
Pod deployments fail with the following event:
FailedCreatePodSandBox kubelet, node01.example.com Failed create pod sandbox: rpc error: code = Unknown desc = NetworkPlugin cni failed to set up pod "example-pod-1-deploy_test" network: failed to find plugin "bridge" in path [/opt/bridge/bin /opt/cni/bin]
Note that this can manifest itself during installation if Ansible is unable to bring up a pod, for example when installing Gluster:
