# PostgreSQL

Postgresql server is required for all the modules. **The Helm charts of respective modules install a unique Postgresql server for each module** - this is to have a clean separation and management of modules. However, in a production setup, you may install only one Postgresql server  (in master-slave configuration) or use a Cloud-native database like Amazon RDS or Azure Postgres Service. 

The procedure below installs an instance of Postgresql using Helm charts if you wish to install Postgresql separately.

* Prerequisites:  the following utilities/tools must be present on the user's machine.
  * `kubectl`, `istioctl`, `helm`, `jq`, `curl`, `wget`, `git`, `bash`, `envsubst`.
* Clone the <https://github.com/openg2p/openg2p-deployment> repo and navigate to the [kubernetes/postgresql](https://github.com/OpenG2P/openg2p-deployment/tree/main/kubernetes/postgresql) directory.
* Run:

  ```bash
  ./install.sh
  ```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.openg2p.org/~/changes/xKUM0sBXFkyR8F24yAMq/deployment/common-components/postgresql.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
