[#limitations]
== Limitations

By default ArgoCD does not expose any means to know the cluster's name/FQDN (Fully Qualified Domain Name)

To make up for this the framework collects some cluster information in order to provide reusable parameters for cluster specific values.

[#variables]
== Domain variables set by the pattern

|===
|**Variable**|**Purpose**|**Example (if applicable)**
| `global.clusterDomain`
| Domain of the cluster the application is running on without the `.apps` subdomain
|`mcg-hub.aws.validatedpatterns.io`
|`global.hubClusterDomain`
| The domain of the hub cluster **with the apps** subdomain - same as `localClusterDomain` on the hub.
| `apps.mcg-hub.aws.validatedpatterns.io`
| `global.localClusterDomain`
| The domain of the cluster the application is running on - **with the apps** subdomain
| `apps.mcg-hub.aws.validatedpatterns.io`
| `global.clusterPlatform`
| Name of the platform
| `aws`, `azure`, `gcp`
| `global.clusterVersion`
| OpenShift Cluster Version
| `4.16`
