Enable rsyslog Service

Description

The rsyslog service provides syslog-style logging by default on Red Hat Enterprise Linux CoreOS 4. The rsyslog service can be enabled with the following manifest:

---
apiVersion: machineconfiguration.openshift.io/v1
kind: MachineConfig
metadata:
  labels:
    machineconfiguration.openshift.io/role: master
  name: 75-master-rsyslog-enable
spec:
  config:
    ignition:
      version: 3.1.0
    systemd:
      units:
      - name: rsyslog.service
        enabled: true

This will enable the rsyslog service in all the nodes labeled with the "master" role.

Note that this needs to be done for each MachineConfigPool

For more information on how to configure nodes with the Machine Config Operator see the relevant documentation.

Rationale

The rsyslog service must be running in order to provide logging services, which are essential to system administration.
