Each cluster node requires an external network interface. Create all external 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>, <external_subnet_id>, <external_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 that contain the cluster name and node number information.
aws ec2 create-network-interface --private-ip-address <ip_addr> --subnet-id <external_subnet_id> --groups <external_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>-ext-1}]”
Below is an example to create external network interfaces for 4 nodes:
> aws ec2 create-network-interface --private-ip-address 10.0.0.4 --subnet-id subnet-058548a2c6df9591c --groups sg-0f43cc7cb8a51cff1 --region us-east-1 --tag-specifications “ResourceType=network-interface,Tags=[{Key=cluster-name,Value=vonefs-cfv},{Key=Name,Value=vonefs-cfv-node1-ext-1}]”
> aws ec2 create-network-interface --private-ip-address 10.0.0.5 --subnet-id subnet-058548a2c6df9591c --groups sg-0f43cc7cb8a51cff1 --region us-east-1 --tag-specifications “ResourceType=network-interface,Tags=[{Key=cluster-name,Value=vonefs-cfv},{Key=Name,Value=vonefs-cfv-node2-ext-1}]”
> aws ec2 create-network-interface --private-ip-address 10.0.0.6 --subnet-id subnet-058548a2c6df9591c --groups sg-0f43cc7cb8a51cff1 --region us-east-1 --tag-specifications “ResourceType=network-interface,Tags=[{Key=cluster-name,Value=vonefs-cfv},{Key=Name,Value=vonefs-cfv-node3-ext-1}]”
> aws ec2 create-network-interface --private-ip-address 10.0.0.7 --subnet-id subnet-058548a2c6df9591c --groups sg-0f43cc7cb8a51cff1 --region us-east-1 --tag-specifications “ResourceType=network-interface,Tags=[{Key=cluster-name,Value=vonefs-cfv},{Key=Name,Value=vonefs-cfv-node4-ext-1}]”
