# Deploying ToolJet on Openshift

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

ToolJet comes with a built-in Redis setup, which is used for multiplayer editing and background jobs. However, for multi-pod setups, it's recommended to use an external Redis instance.
:::

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.

```
TOOLJET_HOST=<Endpoint url>
LOCKBOX_MASTER_KEY=<generate using openssl rand -hex 32>
SECRET_KEY_BASE=<generate using openssl rand -hex 64>

PG_USER=<username>
PG_HOST=<postgresql-instance-ip>
PG_PASS=<password>
PG_DB=tooljet_production
```
Also, for setting up additional environment variables in the .env file, please check our documentation on environment variables [here](/docs/setup/env-vars).

:::warning
To enable ToolJet AI features in your ToolJet deployment, whitelist `https://api-gateway.tooljet.ai`.
:::

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

:::note
When entering one or more files and use --- to separate each definition
:::

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

Use the ToolJet-hosted database to build apps faster, and manage your data with ease. You can learn more about this feature [here](/docs/tooljet-db/tooljet-database).

Deploying ToolJet Database is mandatory from ToolJet 3.0 or else the migration might break. Checkout the following docs to know more about new major version, including breaking changes that require you to adjust your applications accordingly:

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

#### Setting Up ToolJet Database

To set up ToolJet Database, the following **environment variables are mandatory** and must be configured:

```env
TOOLJET_DB=
TOOLJET_DB_HOST=
TOOLJET_DB_USER=
TOOLJET_DB_PASS=
```

Additionally, for **PostgREST**, the following **mandatory** environment variables must be set:

:::tip
If you have openssl installed, you can run the 
command `openssl rand -hex 32` to generate the value for `PGRST_JWT_SECRET`.

If this parameter is not specified, PostgREST will refuse authentication requests.
:::

```env
PGRST_HOST=localhost:3001
PGRST_LOG_LEVEL=info
PGRST_DB_PRE_CONFIG=postgrest.pre_config
PGRST_SERVER_PORT=3001
PGRST_DB_URI=
PGRST_JWT_SECRET=
```

The **`PGRST_DB_URI`** variable is **required** for PostgREST, which exposes the database as a REST API. This must be explicitly set for proper functionality.

#### Format:

```env
PGRST_DB_URI=postgres://TOOLJET_DB_USER:TOOLJET_DB_PASS@TOOLJET_DB_HOST:5432/TOOLJET_DB
```

**Ensure these configurations are correctly set up before proceeding with the ToolJet deployment. Make sure these environment variables are set in the same environment as the ToolJet deployment.**

## 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.
