Bug 1656359

Need to update doc for crio container runtime.

need to point out that when nodes use crio, must specify crio openshift_node_group_name for node, or cluster will not work. (which is not necessary before this PR merged)

also adding crio configmap to this section is suggested.

Description of problem:

Using openstack playbooks I'm trying to have an environment such as:

* Masters with cri-o only
* App nodes with cri-o only
* Infra nodes with docker only

So I have:

$ grep osm_use_cockpit all.yml 
osm_use_cockpit: false

$ cat inventory/group_vars/masters.yml 
openshift_use_crio_only: true
openshift_use_crio: true
openshift_node_group_name: node-config-master-crio

$ cat inventory/group_vars/openstack_compute_nodes.yml 
openshift_use_crio_only: true
openshift_use_crio: true
openshift_node_group_name: node-config-compute-crio

$ cat inventory/group_vars/openstack_infra_nodes.yml 
openshift_use_crio_only: false
openshift_use_crio: false
openshift_node_group_name: node-config-infra

Also, I need to 'patch' the roles/openshift_node/defaults/main.yml until this is released https://github.com/openshift/openshift-ansible/pull/10501/files

The installer skips docker installation in cri-o nodes but when creating the node-config.yaml file for infra nodes, it edits the node-config-infra to add the cri-o settings even if it shouldn't. Logs:

Actual results:
See above.

Expected results:
node-config-infra configmap is not modified

Additional info:
BOOTSTRAP_CONFIG_NAME in /etc/sysconfig/atomic-openshift-node is properly set to 'node-config-infra', the issue is that the node-config is modified and it shouldn't.

I've tested the same scenario but setting per host variables instead per group with same result.

I've been looking into this and found there is a possible issue with the oc_configmap module.  When it attempts to retrieve the configmaps, it fails, and then uses the default configmap template from the openshift_node_group role.  However, the template is processed as if it was on the master, which is set for use_crio, and therefore ends up including the crio settings.  Looking into a fix.
