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.

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

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

3. Create k8s deployment

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.

:::info 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 :::

:::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. :::

:::warning To enable ToolJet AI features in your ToolJet deployment, whitelist api-gateway.tooljet.ai and docs.tooljet.ai. :::

4. Create k8s service

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

5. Create k8s ingress

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

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. :::

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.

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

1. Setup PostgREST server

   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 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 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.

Additional Step for Upgrading from v3.0.33-ee-lts to the Latest LTS Version

If you are upgrading from version v3.0.33-ee-lts to the latest LTS, please ensure that the following configuration is done:

Setup ChromaDB Deployment.

Currently, ChromaDB does not have support for Kubernetes.

1. To use ChromaDB, you need to set up a VM, deploy ChromaDB on it, and then connect to it for usage.

This service helps to deploy chromadb using docker-compose.

name: ChromaDB

services:
 chroma:
   name: chromadb
   image: chromadb/chroma
   ports:
     - "8000:8000"
   environment:
     - CHROMA_HOST_ADDR=0.0.0.0
     - CHROMA_HOST_PORT=8000
   volumes:
     - chromadb_data:/chroma

volumes:
 chromadb_data:
   driver: local

2. Add these environment variable in the ToolJet deployment file:

- name: CHROMA_DB_URL
  value: <instance_ip:8000>

- name: AI_GATEWAY_URL
  value: https://api-gateway.tooljet.ai
