# Deploying the PostgreSQL database

There are multiple ways to deploy a Postgres database server. The following describes how to do so using either Docker containers or Helm charts.

Before starting the deployment, please be informed of the following:

* You can use your existing Postgres DB.
* It is recommended to use Postgres version 14 or above.
* The user must have read and write privileges to the dedicated database.
