# Deploying ToolJet on Kubernetes (GKE)

:::info
You should setup a PostgreSQL database manually to be used by ToolJet. We recommend using Cloud SQL since this guide is for deploying using GKE.
:::

Follow the steps below to deploy ToolJet on a GKE Kubernetes cluster.

1. Create an SSL certificate.

```bash
curl -LO https://tooljet-deployments.s3.us-west-1.amazonaws.com/kubernetes/GKE/certificate.yaml
```

Change the domain name to the domain/subdomain that you wish to use for ToolJet installation.

2. Reserve a static IP address using `gcloud` cli

```bash
gcloud compute addresses create tj-static-ip --global
```

3. Create k8s deployment

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

Make sure to edit the environment variables in the `deployment.yaml`. You can check out the available options [here](/docs/setup/env-vars).

:::info
        For the setup, ToolJet requires:
        <ul> 
        - **TOOLJET_DB** 
        - **TOOLJET_DB_HOST**
        - **TOOLJET_DB_USER**
        - **TOOLJET_DB_PASS**
        - **PG_HOST**
        - **PG_DB**
        - **PG_USER**
        - **PG_PASS**
        - **SECRET_KEY_BASE** 
        - **LOCKBOX_KEY**
        </ul>
        Read **[environment variables reference](/docs/setup/env-vars)**
:::

:::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. Create k8s service

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

5. Create k8s ingress

```bash
curl -LO https://tooljet-deployments.s3.us-west-1.amazonaws.com/kubernetes/GKE/ingress.yaml
```

Change the domain name to the domain/subdomain that you wish to use for ToolJet installation.

6. Apply YAML configs

```bash
kubectl apply -f certificate.yaml, deployment.yaml, service.yaml, ingress.yaml
```

:::info
It might take a few minutes to provision the managed certificates. [Managed certificates documentation](https://cloud.google.com/kubernetes-engine/docs/how-to/managed-certs).
:::

You will be able to access your ToolJet installation once the pods, service and the ingress is running.

## 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.
