= Machine pools in {hcp-title} clusters
8+
9+
In {hcp-title} clusters, the hosted control plane spans three availability zones (AZ) in the installed cloud region. Each machine pool in a {hcp-title} cluster deploys in a single subnet within a single AZ. Each of these AZs can have only one machine pool.
10+
11+
Each machine pool in an {hcp-title} cluster upgrades independently. Because the machine pools upgrade independently, they must remain within 2 minor (Y-stream) versions of the hosted control plane. For example, if your hosted control plane is 4.16.z, your machine pools must be at least 4.14.z.
12+
13+
The following image depicts how machine pools work within ROSA and {hcp-title} clusters:

[NOTE]

====
19+
Machine pools in {hcp-title} clusters each upgrade independently and the machine pool versions must remain within two minor (Y-stream) versions of the control plane.

= Adding tags to a machine pool using the ROSA CLI
8+
9+
You can add tags to a machine pool for your {product-title} cluster by using the ROSA command line interface (CLI).
10+
11+
[IMPORTANT]
12+
====
13+
You must ensure that your tag keys are not `aws`, `red-hat-managed`, `red-hat-clustertype`, or `Name`. In addition, you must not set a tag key that begins with `kubernetes.io/cluster/`. Your tag's key cannot be longer than 128 characters, while your tag's value cannot be longer than 256 characters. Red{nbsp}Hat reserves the right to add additional reserved tags in the future.
14+
====
15+
16+
.Prerequisites
17+
18+
* You installed and configured the latest AWS (`aws`), ROSA (`rosa`), and OpenShift (`oc`) CLIs on your workstation.
19+
* You logged in to your Red{nbsp}Hat account by using the `rosa` CLI.
20+
* You created a {product-title} (ROSA) cluster.
21+
22+
.Procedure
23+
24+
* Create a machine pool with a custom tag by running the following command:
25+
+

----
32+

* Use the `describe` command to see the details of the machine pool with the tags, and verify that the tags are included for your machine pool in the output:

You can add tags for compute nodes, also known as worker nodes, in a machine pool to introduce custom user tags for AWS resources that are generated when you provision your machine pool.
