# Cluster Resource Administration

This directory includes Kubernetes resources that should be installed on
Kubernetes clusters that will have GeoSphere deployed on them. While there
may be local cluster builtin equivalents to the resources defined here, these
builtin names are not used in the current configuration in this deploy
repository. The builtin resources could be used instead of installing the
resources defined in this directory by updating the `values-X.yaml` files in
the various directories and in the `.gitlab-ci.yml` configuration file.

## Storage - Local Large Cache

This storage class and persistent volume can be used for cases where a
GeoSphere component needs relatively high performance and
large capacity storage. Both the StorageClass and the PersistentVolume
are defined in `local-large-cache.yaml`. This storage is primarily used
for GeoSphere's tile cache (used by MapCache). It defines large storage
that is physically located/connected to the node where the pod is being
run or at least performs like it is. The term "large" here refers to
multiple terabytes (3-10TB). While this isn't large in generic storage
terms, it is considered large for a "cache" which is not guaranteed to
persist.

To apply:

```bash
kubectl apply -f local-large-cache.yaml
```

## Storage - Local Medium Archive

Similar to Local Large Cache above, but larger available space. Note this
should only be used for testing as data will be deleted when the claim
is removed.
