Documentation for MachineConfig custom file creation

Jump to solution

Hello,

I am preparing for EX380V4.10 and trying to run "Guided Exercise: Creating Custom Machine Config Pools"(7.4 Section) in DO380V4.10 without using the prepared MC and MCP yaml files.

However I cannot find any reference for that kind of operations(custom file management in nodes using MC) in Openshift Documentation (https://access.redhat.com/documentation/en-us/openshift_container_platform/4.10/html/nodes).

Is there any place in Documentation or any other way that I can find this information, without the need to remember the whole yaml files?

Regards

You can always get an example of MCP with, oc get machineconfigpool , but for MC examples, check out: Using MachineConfig objects to configure nodes in the Post Installation Configuration docs.

Hello,

This is a good example, however I see that the butane tool is used to create the MachineConfig. Will this tool be available at the exam? Currently I cannot find it in the DO380 Labs...

Hello @dimos_varounis Certainly! The Butane tool will already be installed within the environment, eliminating the necessity to download the binaries.

You just have to follow the below instructions in the exam for MCP question:

  • - Take referance from the given docs.
  • - In the docs search for the day2.
  • - Now, in the day2 section of docs search for chrony.
  • - Apply those instructions and ensure that the changes are applied to the nodes.

Don't worry butane binary would be there to help.
You'll get this documentation there: https://docs.openshift.com/container-platform/4.13/post_installation_configuration/machine-configura...

When help is available then don't invest time in remembering the yaml indentation.
