Chapter 10. Network configuration

Procedure

1. Follow the instructions for registering a new cluster by using the API. For details, see Registering a new cluster.

2. Add the following payload settings to the cluster configuration:

   1. Set vip_dhcp_allocation to true.
   2. Set network_type to OpenShiftSDN.
   3. Include your network configurations for cluster_networks, service_networks, and machine_networks.

   Example payload to enable autoallocation

   $ cat << EOF > payload.json
   
   {
     "vip_dhcp_allocation": true,
     "network_type": "OpenShiftSDN",
     "user_managed_networking": false,
     "cluster_networks": [
       {
         "cidr": "10.128.0.0/14",
         "host_prefix": 23
       }
     ],
     "service_networks": [
       {
         "cidr": "172.30.0.0/16"
       }
     ],
     "machine_networks": [
       {
         "cidr": "192.168.127.0/24"
       }
     ]
   }
   
   EOF

3. Submit the payload to the Assisted Service API to apply the configuration, by running the following command:

   $ curl -s -X POST "https://api.openshift.com/api/assisted-install/v2/clusters/<cluster-id>" \
     -d @./payload.json \
     -H "Content-Type: application/json" \
     -H "Authorization: Bearer $API_TOKEN" \
     | jq '.id'

2. Add the following payload settings to the cluster configuration:

   1. Set vip_dhcp_allocation to false.
   2. Specify the IP addresses for api_vips and ingress_vips. You can take these IPs from your machine_networks configuration.
   3. Set network_type to OVNKubernetes, OpenShiftSDN, or another supported SDN type, if applicable.
   4. Include your network configurations for cluster_networks and service_networks.

   Example payload to disable autoallocation

   $ cat << EOF > payload.json
   
   {
     "api_vips": [
       {
           "ip": "192.168.127.100"
       }
     ],
     "ingress_vips": [
       {
           "ip": "192.168.127.101"
       }
     ],
     "vip_dhcp_allocation": false,
     "network_type": "OVNKubernetes",
     "user_managed_networking": false,
     "cluster_networks": [
       {
         "cidr": "10.128.0.0/14",
         "host_prefix": 23
       }
     ],
     "service_networks": [
       {
         "cidr": "172.30.0.0/16"
       }
     ]
   }
