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

  1. Disable usage of chrony module in the deckhouse ConfigMap:

    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
