openshift/extra-manifests¶

List of DRP templates to render as extra OpenShift manifests during cluster creation

This parameter defines a list of DRP template names that will be rendered and written to the /root/cluster/openshift/ directory before openshift-install agent create pxe-files runs. Any valid OpenShift manifest can be injected this way — MachineConfigs, Secrets, ConfigMaps, operator configs, etc.

Each template is rendered against the cluster machine context, so it has access to all cluster parameters via the standard DRP template functions (.Param, .ParamExpand, .ParamComposeExpand, etc.).

The rendered output is written to a file named after the template (e.g., my-machineconfig.yaml.tmpl produces my-machineconfig.yaml).

Requirements¶

Each template must exist in the DRP content bundle
Each template must produce valid YAML when rendered

Usage¶

YAML

openshift/extra-manifests:
  - machineconfig-disable-auto-dhcp.yaml.tmpl
  - machineconfig-custom-kubelet.yaml.tmpl
  - configmap-cluster-monitoring.yaml.tmpl

Example: Disable NetworkManager Auto-DHCP¶

Create a template machineconfig-disable-auto-dhcp.yaml.tmpl:

YAML

---
apiVersion: machineconfiguration.openshift.io/v1
kind: MachineConfig
metadata:
  labels:
    machineconfiguration.openshift.io/role: worker
  name: 99-worker-disable-auto-dhcp
spec:
  config:
    ignition:
      version: 3.2.0
    storage:
      files:
      - contents:
          source: data:,%5Bmain%5D%0Ano-auto-default%3D%2A%0A
        mode: 420
        path: /etc/NetworkManager/conf.d/no-auto-default.conf

Then add it to the cluster profile:

YAML

openshift/extra-manifests:
  - machineconfig-disable-auto-dhcp.yaml.tmpl
