ToolJet comes with a **built-in Redis setup**, which is used for multiplayer editing and background jobs. However, for **multi-pod setup**, it's recommended to use an **external Redis instance**.
- Add the following ToolJet application variables under the "Environmental variable" section. You can refer to this [**documentation**](/docs/setup/env-vars) for more information on environment variables.
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 # Must be a unique database name (separate from PG_DB and not shared)
TOOLJET_DB_HOST=<postgresql-database-host>
TOOLJET_DB_USER=<username>
TOOLJET_DB_PASS=<password>
```
:::note
Ensure that `TOOLJET_DB` is not the same as `PG_DB`. Both databases must be uniquely named and not shared.
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.
**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 container.**
**Note:** These environment variables are in general and might change in the future. You can also refer env variable [**here**](/docs/setup/env-vars).
5. In the ingress tab, configure Ingress and Authentication settings as shown below. You can customize the security configurations as per your requirements. Make sure the port is set to 3000.
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`.
