A note on the chart's purpose | ||
----------------------------- | ||
|
||
This is an opinionated chart that is designed to provide a subset of simple, stable and safe configurations using the | ||
CloudNativePG operator. It is designed to provide a simple way to perform recovery operations to decrease your RTO. | ||
|
||
It is not designed to be a one size fits all solution. If you need a more complicated setup we strongly recommend that | ||
you either: | ||
|
||
* use the operator directly | ||
* create your own chart | ||
* use Kustomize to modify the chart's resources | ||
|
||
**_Note_** that the latter option carries it's own risks as the chart configuration may change, especially before it | ||
reaches a stable release. | ||
|
||
That being said, we welcome PRs that improve the chart, but please keep in mind that we don't plan to support every | ||
single configuration that the operator provides and we may reject PRs that add too much complexity and maintenance | ||
difficulty to the chart. | ||
|
||
|
||
Getting Started | ||
--------------- | ||
|
||
### Installing the Operator | ||
Skip this step if the CNPG operator is already installed in your cluster. | ||
|
||
```console | ||
helm repo add cnpg https://cloudnative-pg.github.io/charts | ||
helm upgrade --install cnpg \ | ||
--namespace cnpg-system \ | ||
--create-namespace \ | ||
cnpg/cloudnative-pg | ||
``` | ||
|
||
### Setting up a CNPG Cluster | ||
|
||
```console | ||
helm repo add paradedb https://paradedb.github.io/charts | ||
helm upgrade --install paradedb \ | ||
--namespace paradedb-database \ | ||
--create-namespace \ | ||
--values values.yaml \ | ||
paradedb/cluster | ||
``` | ||
|
||
A more detailed guide can be found in the [Getting Started docs](<./docs/Getting Started.md>). | ||
|
||
|
||
Cluster Configuration | ||
--------------------- | ||
|
||
### Database types | ||
|
||
Currently the chart supports two database types. These are configured via the `type` parameter. These are: | ||
* `postgresql` - A standard PostgreSQL database. | ||
* `postgis` - A PostgreSQL database with the PostGIS extension installed. | ||
* `timescaledb` - A PostgreSQL database with the TimescaleDB extension installed. | ||
* `paradedb` - A PostgreSQL database with the ParadeDB extensions (`pg_search` and `pg_analytics`) installed. | ||
|
||
Depending on the type the chart will use a different Docker image and fill in some initial setup, like extension installation. | ||
|
||
### Modes of operation | ||
|
||
The chart has three modes of operation. These are configured via the `mode` parameter: | ||
* `standalone` - Creates new or updates an existing CNPG cluster. This is the default mode. | ||
* `replica` - Creates a replica cluster from an existing CNPG cluster. **_Note_ that this mode is not yet supported.** | ||
* `recovery` - Recovers a CNPG cluster from a backup, object store or via pg_basebackup. | ||
|
||
### Backup configuration | ||
|
||
CNPG implements disaster recovery via [Barman](https://pgbarman.org/). The following section configures the barman object | ||
store where backups will be stored. Barman performs backups of the cluster filesystem base backup and WALs. Both are | ||
stored in the specified location. The backup provider is configured via the `backups.provider` parameter. The following | ||
providers are supported: | ||
|
||
* S3 or S3-compatible stores, like MinIO | ||
* Microsoft Azure Blob Storage | ||
* Google Cloud Storage | ||
|
||
Additionally you can specify the following parameters: | ||
* `backups.retentionPolicy` - The retention policy for backups. Defaults to `30d`. | ||
* `backups.scheduledBackups` - An array of scheduled backups containing a name and a crontab schedule. Example: | ||
```yaml | ||
backups: | ||
scheduledBackups: | ||
- name: daily-backup | ||
schedule: "0 0 0 * * *" # Daily at midnight | ||
backupOwnerReference: self | ||
``` | ||
|
||
Each backup adapter takes it's own set of parameters, listed in the [Configuration options](#Configuration-options) section | ||
below. Refer to the table for the full list of parameters and place the configuration under the appropriate key: `backup.s3`, | ||
`backup.azure`, or `backup.google`. | ||
|
||
|
||
Recovery | ||
-------- | ||
|
||
There is a separate document outlining the recovery procedure here: **[Recovery](docs/recovery.md)** | ||
|
||
|
||
Examples | ||
-------- | ||
|
||
There are several configuration examples in the [examples](examples) directory. Refer to them for a basic setup and | ||
refer to the [CloudNativePG Documentation](https://cloudnative-pg.io/documentation/current/) for more advanced configurations. | ||
