You should setup a PostgreSQL database manually to be used by ToolJet. We recommend using Azure Database for PostgreSQL since this guide is for deploying using AKS.
:::
Follow the steps below to deploy ToolJet on a AKS Kubernetes cluster.
1. Create an AKS cluster and connect to it to start with the deployment. You can follow the steps as mentioned on the [Azure's documentation](https://docs.microsoft.com/en-us/azure/aks/kubernetes-walkthrough-portal).
Make sure to edit the environment variables in the `deployment.yaml`. We advise to use secrets to setup sensitive information. You can check out the available options [here](/docs/setup/env-vars).
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.
:::
3. Create k8s service and reserve a static IP and expose it via a service load balancer as mentioned in the [doc](https://docs.microsoft.com/en-us/azure/aks/static-ip). You can refer `service.yaml`.
You will be able to access your ToolJet installation once the pods and services running.
## ToolJet Database
To use ToolJet Database, you'd have to set up and deploy PostgREST server which helps querying ToolJet Database. Please [follow the instructions here](/docs/setup/env-vars#tooljet-database).
2. Update ToolJet deployment with the appropriate env variables [here](https://tooljet-deployments.s3.us-west-1.amazonaws.com/kubernetes/AKS/deployment.yaml) and apply the changes.
## Workflows
ToolJet Workflows allows users to design and execute complex, data-centric automations using a visual, node-based interface. This feature enhances ToolJet's functionality beyond building secure internal tools, enabling developers to automate complex business processes.
**Note:** Ensure that the worker deployment uses the same image as the ToolJet application deployment to maintain compatibility. Additionally, the variables below need to be a part of tooljet-deployment.
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.
