Each cluster node requires an internal network interface. Create all internal network interfaces for your cluster nodes with the planned IPs in section Prerequisites checklist details and example.
Run the following command by replacing the <ip_addr>, <internal_subnet_id>, <internal_security_group_id>, <aws_region>, <cluster_name>, and <node_number> with your own settings. To manage cluster nodes conveniently in the future, it is recommended that you add the two tags, which contain the cluster name and node number information.
aws ec2 create-network-interface --private-ip-address <ip_addr> --subnet-id <internal_subnet_id> --groups <internal_security_group_id> --region <aws_region> --tag-specifications “ResourceType=network-interface,Tags=[{Key=cluster-name,Value=<cluster_name>},{Key=Name,Value=<cluster_name>-node<node_number>-int-a}]”
Below is an example to create the internal network interfaces for four nodes:
> aws ec2 create-network-interface --private-ip-address 10.0.0.20 --subnet-id subnet-0dc84f8a0a6f8dd8d --groups sg-07f220483ab7e3bf7 --region us-east-1 --tag-specifications “ResourceType=network-interface,Tags=[{Key=cluster-name,Value=vonefs-cfv},{Key=Name,Value=vonefs-cfv-node1-int-a}]”
> aws ec2 create-network-interface --private-ip-address 10.0.0.21 --subnet-id subnet-0dc84f8a0a6f8dd8d --groups sg-07f220483ab7e3bf7 --region us-east-1 --tag-specifications “ResourceType=network-interface,Tags=[{Key=cluster-name,Value=vonefs-cfv},{Key=Name,Value=vonefs-cfv-node2-int-a}]”
> aws ec2 create-network-interface --private-ip-address 10.0.0.22 --subnet-id subnet-0dc84f8a0a6f8dd8d --groups sg-07f220483ab7e3bf7 --region us-east-1 --tag-specifications “ResourceType=network-interface,Tags=[{Key=cluster-name,Value=vonefs-cfv},{Key=Name,Value=vonefs-cfv-node3-int-a}]”
> aws ec2 create-network-interface --private-ip-address 10.0.0.23 --subnet-id subnet-0dc84f8a0a6f8dd8d --groups sg-07f220483ab7e3bf7 --region us-east-1 --tag-specifications “ResourceType=network-interface,Tags=[{Key=cluster-name,Value=vonefs-cfv},{Key=Name,Value=vonefs-cfv-node4-int-a}]”
