# Deploying ToolJet on Openshift

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

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 setup, ToolJet requires:
 - **TOOLJET_DB** 
 - **TOOLJET_DB_HOST**
 - **TOOLJET_DB_USER**
 - **TOOLJET_DB_PASS**
 - **PG_HOST**
 - **PG_DB**
 - **PG_USER**
 - **PG_PASS**
 - **SECRET_KEY_BASE** 
 - **LOCKBOX_KEY**

Read **[environment variables reference](/docs/setup/env-vars)**

3. Once you have logged into the Openshift developer dashboard click on `+Add` tab. Select import YAML from the local machine.

:::

Copy paste deployment.yaml to the online editor 

```
curl -LO https://tooljet-deployments.s3.us-west-1.amazonaws.com/openshift/deployment.yaml
```

Copy paste the service.yaml to the online editor

```
curl -LO https://tooljet-deployments.s3.us-west-1.amazonaws.com/openshift/service.yaml
```

</div>

Once you have added the files click on create.

:info
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.

## ToolJet Database

To use the ToolJet Database, you need to set up and deploy a PostgREST server, which facilitates querying the database. Detailed setup instructions are available [here](/docs/tooljet-db/tooljet-database).

Starting with ToolJet 3.0, deploying the ToolJet Database is mandatory to avoid migration issues. Refer to the documentation below for details on the new major version, including breaking changes and required adjustments for your applications.

- [ToolJet 3.0 Migration Guide for Self-Hosted Versions](./upgrade-to-v3.md)

1. Setup PostgREST server

   ```bash
   kubectl apply -f https://tooljet-deployments.s3.us-west-1.amazonaws.com/kubernetes/GKE/postgrest.yaml
   ```

2. Update ToolJet deployment with the appropriate env variables [here](https://tooljet-deployments.s3.us-west-1.amazonaws.com/kubernetes/GKE/deployment.yaml) and apply the changes.

## Upgrading to the Latest LTS Version

New LTS versions are released every 3-5 months with an end-of-life of atleast 18 months. To check the latest LTS version, visit the [ToolJet Docker Hub](https://hub.docker.com/r/tooljet/tooljet/tags) page. The LTS tags follow a naming convention with the prefix `LTS-` followed by the version number, for example `tooljet/tooljet:ee-lts-latest`.

If this is a new installation of the application, you may start directly with the latest version. This guide is not required for new installations.

#### Prerequisites for Upgrading to the Latest LTS Version:

- It is crucial to perform a **comprehensive backup of your database** before starting the upgrade process to prevent data loss.

- Users on versions earlier than **v2.23.0-ee2.10.2** must first upgrade to this version before proceeding to the LTS version.
