Creating node pools on the multi-architecture hosted cluster

After you transition your hosted cluster from single-architecture to multi-architecture, create node pools on compute machines based on 64-bit AMD and 64-bit ARM architectures.

Procedure

Create node pools based on 64-bit ARM architecture by entering the following command:
```
$ hcp create nodepool aws \
  --cluster-name <hosted_cluster_name> \
  --name <nodepool_name> \
  --node-count=<node_count> \
  --arch arm64
```
- Replace <hosted_cluster_name> with your hosted cluster name.
- Replace <nodepool_name> with your node pool name.
- Replace <node_count> with integer for your node count, for example, 2.
Create node pools based on 64-bit AMD architecture by entering the following command:
```
$ hcp create nodepool aws \
  --cluster-name <hosted_cluster_name> \
  --name <nodepool_name> \
  --node-count=<node_count> \
  --arch amd64
```
- Replace <hosted_cluster_name> with your hosted cluster name.
- Replace <nodepool_name> with your node pool name.
- Replace <node_count> with integer for your node count, for example, 2.

Verification

Verify that a node pool is using the multi-architecture release image by entering the following command:

$ oc get nodepool/<nodepool_name> -oyaml
