How to scale MongoDB using Terraform [Amazon Web Service] ECS and EKS

Deploy MongoDB on AWS ECS with Terraform

Follow these steps to deploy MongoDB on AWS ECS:

1. Create an ECS Cluster:

            
provider "aws" {
  region = "your-aws-region"
}

resource "aws_ecs_cluster" "mongodb_cluster" {
  name = "mongodb-cluster"
}
            
        

2. Create a Task Definition:

            
resource "aws_ecs_task_definition" "mongodb_task" {
  family                   = "mongodb"
  network_mode             = "bridge"
  requires_compatibilities = ["EC2"]
  cpu                      = "256"
  memory                   = "512"

  container_definitions = jsonencode([{
    name  = "mongodb-container"
    image = "your-mongodb-docker-image"
    portMappings = [{
      containerPort = 27017,
      hostPort      = 27017,
    }]
  }])
}
            
        

3. Create an ECS Service:

            
resource "aws_ecs_service" "mongodb_service" {
  name            = "mongodb-service"
  cluster         = aws_ecs_cluster.mongodb_cluster.id
  task_definition = aws_ecs_task_definition.mongodb_task.arn
  launch_type     = "EC2"
  desired_count   = 3  # Adjust this based on your scaling requirements

  network_configuration {
    subnets = aws_subnet.private.*.id
    security_groups = [aws_security_group.mongodb.id]
  }
}
            
        

Make sure to replace placeholder values such as "your-aws-region" and "your-mongodb-docker-image" with your actual values.
