Critical Description of problem:
On "changing the cluster network MTU" doc v4.15. While creating MachineConfig objects from butane, the version is mentioned 4.15.0.
However when translating this butane file into yaml, we are getting below error:
~~~
[utgupta@utgupta ~]$ ./butane --files-dir . control-plane-interface.bu > control-plane-interface.yaml
Error translating config: No translator exists for variant openshift with version 4.15.0
~~~
This error means butane translator doesn't exist for v4.15.0.
When specifying 4.15.0-experimental in the .bu file, the generated .yaml file has ignition.version being 3.5.0-experimental, and after creating the 3.5.0-experimental MachineConfig, the machine-config-controller Pod shows the following errors in my 4.15.0-rc.5 test environment:
~~~
$ oc logs machine-config-controller-869fbd5d96-lcbx7
<..snip..>
E0212 01:45:21.736644 1 render_controller.go:439] Error syncing Generated MCFG: %!w(*errors.errorString=&{parsing Ignition config failed: unknown version. Supported spec versions: 2.2, 3.0, 3.1, 3.2, 3.3, 3.4})
~~~
When specifying 4.14.0 in the .bu file, the generated .yaml file has ignition.version being 3.4.0 and everything works fine in my 4.15.0-rc.5 test environment.
Document should mention v4.14.0 instead of v4.15.0 till butane translator exists for v4.15.0.
How reproducible:
Always
