How do I disable chrony and use ntp daemon on nodes?

  1. Disable usage of chrony module in Deckhouse CM:
    chronyEnabled: "false"
    
  2. Create NodeGroupConfiguration custom step to enable use ntp daemon on nodes (example for systemd-timesyncd):
    apiVersion: deckhouse.io/v1alpha1
    kind: NodeGroupConfiguration
    metadata:
      name: enable_ntp_on_node.sh
    spec:
      weight: 100
      nodeGroups: ["*"]
      bundles: ["*"]

     systemctl enable systemd-timesyncd
     systemctl start systemd-timesyncd
