Deploying ToolJet on Kubernetes

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 setup, it's recommended to use an external Redis instance.

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

  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_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.

warning

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

  1. Create a Kubernetes deployment

    kubectl apply -f https://tooljet-deployments.s3.us-west-1.amazonaws.com/kubernetes/deployment.yaml
info

The file given above is just a template and might not suit production environments. You should download the file and configure parameters such as the replica count and environment variables according to your needs.

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.

  1. Verify if ToolJet is running

     kubectl get pods

  2. Create a Kubernetes services to publish the Kubernetes deployment that you've created. This step varies with cloud providers. We have a template for exposing the ToolJet server as a service using an AWS loadbalancer.

    Examples:

tip

If you want to serve ToolJet client from services such as Firebase or Netlify, please read the client Setup documentation here.

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.

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:

Setting Up ToolJet Database​

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

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.

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:​

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 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.
