If you already have existing services and wish to integrate ToolJet seamlessly into your current Virtual Private Cloud (VPC) or other setups, you can opt for the following template:
ToolJet requires configuring Redis which is used for enabling multiplayer editing and for background jobs.
:::
To deploy Redis on an ECS cluster, please follow the steps outlined below.
Please note that if you already have an existing Redis setup, you can continue using it. However, if you need to create a new Redis service, you can follow the steps provided below.
Follow the steps below to deploy ToolJet on a ECS cluster.
1. Setup a PostgreSQL database ToolJet uses a postgres database as the persistent storage for storing data related to users and apps.
2. Create a target group and an application load balancer to route traffic onto ToolJet containers. You can [reference](https://docs.aws.amazon.com/AmazonECS/latest/userguide/create-application-load-balancer.html) AWS docs to set it up. Please note that ToolJet server exposes `/api/health`, which you can configure for health checks.
3. Create task definition for deploying ToolJet app as a service on your preconfigured cluster.
i. Select Fargate as launch type compatibility
ii. Configure IAM roles and set operating system family as Linux.
iii. Select task size to have 3GB of memory and 1vCpu
Specify environmental values for the container. You'd want to make use of secrets to store sensitive information or credentials, kindly refer the AWS [docs](https://docs.aws.amazon.com/AmazonECS/latest/developerguide/specifying-sensitive-data-secrets.html) to set it up. You can also store the env in S3 bucket, kindly refer the AWS [docs](https://docs.aws.amazon.com/AmazonECS/latest/developerguide/taskdef-envfiles.html) .
For the minimal setup, ToolJet requires: `TOOLJET_HOST`, `PG_HOST`, `PG_DB`, `PG_USER`, `PG_PASSWORD`, `SECRET_KEY_BASE`&`LOCKBOX_MASTER_KEY` keys in the secret.
Additionally, include the Redis environment variables within the ToolJet container mentioned above if you have followed the previous steps to create Redis.
```
REDIS_HOST=<publicipofredistask>
REDIS_PORT=6379
REDIS_USER=default
REDIS_PASSWORD=
```
v. Make sure `Use log collection checked` and `Docker configuration` with the command `npm run start:dev`
- Click on next step to configure networking options
- Select your designated VPC, Subnets and Security groups. Kindly ensure that the security group allows for inbound traffic to http port 3000 for the task.
- Since migrations are run as a part of container boot, please specify health check grace period for 900 seconds. Select the application loadbalancer option and set the target group name to the one we had created earlier. This will auto populate the health check endpoints.

The setup above is just a template. Feel free to update the task definition and configure parameters for resources and environment variables according to your needs.

## ToolJet Database
If you intend to use this feature, you'd have to set up and deploy PostgREST server which helps querying ToolJet Database. You can learn more about this feature [here](https://docs.tooljet.com/docs/tooljet-database).
Follow the steps below to deploy PostgREST on a ECS cluster.
Under environmental variable please add corresponding PostgREST env variables. You can also refer [env variable](https://docs.tooljet.com/docs/setup/env-vars/#postgrest-server-optional).
4. Ensure that the PostgREST service resides within the same Virtual Private Cloud (VPC), and confirm that port 3001 is included in the security group used by the ToolJet app. **Note: Please enable public IP**
Update ToolJet deployment with the appropriate env variables [here](https://docs.tooljet.com/docs/setup/env-vars/#enable-tooljet-database--optional-) and apply the changes.
