# Patroni OpenShift Configuration
Patroni can be run in OpenShift. Based on the kubernetes configuration, the Dockerfile and Entrypoint has been modified to support the dynamic UID/GID configuration that is applied in OpenShift. This can be run under the standard `restricted` SCC.
# Examples
## Create test project
```
oc new-project patroni-test
```
## Build the image
Note: Update the references when merged upstream.
Note: If deploying as a template for multiple users, the following commands should be performed in a shared namespace like `openshift`.
```
oc import-image postgres:10 --confirm -n openshift
oc new-build https://github.com/zalando/patroni --context-dir=kubernetes -n openshift
```
## Deploy the Image
Two configuration templates exist in [templates](templates) directory:
- Patroni Ephemeral
- Patroni Persistent
The only difference is whether or not the statefulset requests persistent storage.
## Create the Template
Install the template into the `openshift` namespace if this should be shared across projects:
```
oc create -f templates/template_patroni_ephemeral.yml -n openshift
```
Then, from your own project:
```
oc new-app patroni-pgsql-ephemeral
```
Once the pods are running, two configmaps should be available:
```
$ oc get configmap
NAME DATA AGE
patroniocp-config 0 1m
patroniocp-leader 0 1m
```
