Creates a postgres cluster using the Zalando Postgres operator and local storage

**This chart is not maintained by the upstream project and any issues with the chart should be raised [here](https://github.com/k8s-at-home/charts/issues/new/choose)**

## Requirements

||||||
|
|
||||||
|
## Dependencies
|
||||||
|
|
||||||
|
| Repository | Name | Version |
|
||||||
|
|------------|------|---------|
|
||||||
|
| https://library-charts.k8s-at-home.com | common | 2.1.0 |
|
||||||
|
|
||||||
|
## TL;DR
|
||||||
|
|
||||||
|
```console
|
||||||
|
helm repo add k8s-at-home https://k8s-at-home.com/charts/
|
||||||
|
helm repo update
|
||||||
|
helm install zalando-postgres-cluster k8s-at-home/zalando-postgres-cluster
|
||||||
|
```
|
||||||
|
|
||||||
|
## Installing the Chart
|
||||||
|
|
||||||
|
To install the chart with the release name `zalando-postgres-cluster`
|
||||||
|
|
||||||
|
```console
|
||||||
|
helm install zalando-postgres-cluster k8s-at-home/zalando-postgres-cluster
|
||||||
|
```
|
||||||
|
|
||||||
|
## Uninstalling the Chart
|
||||||
|
|
||||||
|
To uninstall the `zalando-postgres-cluster` deployment
|
||||||
|
|
||||||
|
```console
|
||||||
|
helm uninstall zalando-postgres-cluster
|
||||||
|
```
|
||||||
|
|
||||||
|
The command removes all the Kubernetes components associated with the chart **including persistent volumes** and deletes the release.
|
||||||
|
|
||||||
|
## Configuration
|
||||||
|
|
||||||
|
Read through the [values.yaml](./values.yaml) file. It has several commented out suggested values.
|
||||||
|
Other values may be used from the [values.yaml](https://github.com/k8s-at-home/library-charts/tree/main/charts/stable/common/values.yaml) from the [common library](https://github.com/k8s-at-home/library-charts/tree/main/charts/stable/common).
|
||||||
|
|
||||||
|
Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`.
|
||||||
|
|
||||||
|
```console
|
||||||
|
helm install zalando-postgres-cluster \
|
||||||
|
--set env.TZ="America/New York" \
|
||||||
|
k8s-at-home/zalando-postgres-cluster
|
||||||
|
```
|
||||||
|
|
||||||
|
Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart.
|
||||||
|
|
||||||
|
```console
|
||||||
|
helm install zalando-postgres-cluster k8s-at-home/zalando-postgres-cluster -f values.yaml
|
||||||
|
```
|
||||||
|
|
||||||
|
## Custom configuration
|
||||||
|
|
||||||
|
This chart is a wrapper for the [Zalando postgres operator](https://github.com/zalando/postgres-operator) to create
|
||||||
|
a high available Postgres cluster using nodes local storage.
|
||||||
|
|
||||||
|
Features added by this wrapper:
|
||||||
|
- creates an storage class using local storage in the nodes specified in `persistentVolumes.replicaNodes`. These replicas survive
|
||||||
|
a tear-down and tear-up of the cluster.
|
||||||
|
- (optional) does sql dumps to an existing PVC with K8S cronjobs. The Operator only supports backups to cloud, not NFS PVC for example.
|
||||||
|
- Define the password for the DB so that it can be used accross tear-down and tear-up of the cluster.
|
||||||
|
|
||||||
|

This chart is a wrapper for the [Zalando postgres operator](https://github.com/zalando/postgres-operator) to create
|
||||||
|
a high available Postgres cluster using nodes local storage.
|
||||||
|
|
||||||
|
Features added by this wrapper:
|
||||||
|
- creates an storage class using local storage in the nodes specified in `persistentVolumes.replicaNodes`. These replicas survive
|
||||||
|
a tear-down and tear-up of the cluster.
|
||||||
|
- (optional) does sql dumps to an existing PVC with K8S cronjobs. The Operator only supports backups to cloud, not NFS PVC for example.
|
||||||
|
- Define the password for the DB so that it can be used accross tear-down and tear-up of the cluster.
