Alternatively, you can add the flag `--cluster-user-config` with the values you want to add to the cluster and it will generate a `ConfigMap` with the values.

#### Upgrading workload clusters

To upgrade a workload cluster, you need to change the `release.version` field in the `cluster-user-config` file. After that, you commit and push the changes to the repository. The `Flux` controller will detect the changes and the cluster will be upgraded to the new version. The release version can be found by running `kubectl get releases` in the management cluster. You only need to set the version in the `release.version` field.

Example:

`kubectl get releases`:

```sh
NAME KUBERNETES VERSION FLATCAR VERSION AGE STATE
aws-29.4.0 1.29.10 3975.2.2 29d active
```

You set the `release.version` in the `cluster-user-config` file to `29.4.0` and commit and push the changes.

### Installing managed apps

Installing applications is easy now that you have the GitOps structure in place. In this tutorial you are going to install `Grafana` to understand the process.
