You should setup a PostgreSQL database manually to be used by ToolJet.

*If you have any questions feel free to join our [Slack Community](https://tooljet.com/slack) or send us an email at hello@tooljet.com.*
Follow the steps below to deploy ToolJet on Openshift.
1. Setup a PostgreSQL database ToolJet uses a postgres database as the persistent storage for storing data related to users and apps. We do not have plans to support other databases such as MySQL.
2. Create a Kubernetes secret with name `server`. For the minimal setup, ToolJet requires `pg_host`, `pg_db`, `pg_user`, `pg_password`, `secret_key_base`&`lockbox_key` keys in the secret.
If there are self signed HTTPS endpoints that Tooljet needs to connect to, please make sure that `NODE_EXTRA_CA_CERTS` environment variable is set to the absolute path containing the certificates. You can make use of kubernetes secrets to mount the certificate file onto the containers.

4. Navigate to topology tab and use the visual connector to establish the connect between tooljet-deployment and postgresql as shown in the screenshot below.

If you intend to use this feature, you'd have to set up and deploy PostgREST server which helps querying ToolJet Database. Please [follow the instructions here](https://docs.tooljet.com/docs/setup/env-vars#tooljet-database) for additional environment variables configuration to be done.
Version v2.24.3-ee2.10.2 includes architectural changes and, hence, comes with new migrations.
If this is a new installation of the application, you may start directly with version v2.24.3-ee2.10.2. This guide is not required for new installations.
#### Prerequisites for Upgrading to the Latest Version:
- It is **crucial to perform a comprehensive backup of your database** before starting the upgrade process to prevent data loss.
- Ensure that your current version is v2.23.3-ee2.10.2 before upgrading.
- Users on versions earlier than v2.23.3-ee2.10.2 must first upgrade to this version before proceeding to v2.24.3-ee2.10.2.
