Description Wolfgang Kulhanek 2018-04-02 17:44:59 UTC
Description of problem:

Version-Release number of the following components:
OCP 3.9 GA

How reproducible:

Steps to Reproduce:
1. Try to install OCP with CRI-O support and Garbage Collection Support enabled
2. Install fails with a message that no nodes labelled "runtime=cri-o" are found

This is either an installer or a docs bug. Relevant Docs:


Docs say on "openshift_crio_enable_docker_gc":
When enabled, it will run garbage collection on all nodes by default. You can also limit the running of the daemonset on specific nodes by setting the following:

  openshift_crio_docker_gc_node_selector={'runtime': 'cri-o'}

However this setting seems to be the default and if no nodes in the cluster are labelled as "runtime=cri-o" the install fails.

Comment 1 Johnny Liu 2018-04-03 02:01:38 UTC
We already have a installer bug to track this:

For doc, there is some statement about it:
For example, the above would ensure it is only run on nodes with the runtime: cri-o label. 

From QE's view, the statement is already clear.

Here I will close this bug as a DUP. If you still think the doc is not clear enough, pls reopen it, and move it to "Document" component. Thx.
