What is the precedence for MachineConfigs in OpenShift 4?

Solution Verified - Updated -

Issue

  • A MachineConfig is created in the cluster, but the changes are not applied to the nodes.
  • MCO is not generating new render after a new MachineConfig is created in OpenShift 4.
  • Why a new rendered MachineConfig is not generated with newly created MachineConfig resource?
  • Why a new MachineConfig cannot overwrite changes applied by an old MachineConfig?
  • Can the precedence of MachineConfigs be changed in OCP 4?

Environment

  • Red Hat OpenShift Container Platform (RHOCP)
    • 4
  • Machine Config Operator (MCO)
  • Machine Config (MC)
