Description of problem: We should add user containers in /etc/subuid and /etc/subgid to support run pods in user namespaces. Now /etc/subuid and /etc/subgid only show: core:100000:65536 If we want to run pod in user namespaces, we have to add user containers via a MachineConfig. We should add "containers" entry in /etc/subuid and /etc/subgid by default, for example: containers:200000:268435456 Version-Release number of selected component (if applicable): 4.11.0-0.nightly-2022-03-27-140854 How reproducible: always Steps to Reproduce: 1.create a ocp cluster 2.oc debug node/ip-10-0-158-142.us-east-2.compute.internal 3. sh-4.4# chroot /host sh-4.4# cat /etc/subgid core:100000:65536 sh-4.4# cat /etc/subuid core:100000:65536 Actual results: 3 /etc/sub[u,g]id file only include core:100000:65536 Expected results: 3 /etc/sub[u,g]id file should include entry "containers" Additional info: there is a similar bug in 4.10: https://bugzilla.redhat.com/show_bug.cgi?id=2038827
