Hi Follow These steps to resolve issue
Approach 1: Using a Fixed Task Definition
One way to force a deployment without creating a new task definition is to reuse the same task definition revision. You can achieve this by updating the service to use the same task definition revision and force a new deployment. This can be done through the AWS CLI or SDK, but here’s how to integrate it into a CodePipeline setup:
- Create a Lambda Function: This function will update the ECS service to force a new deployment using the same task definition revision.
- Invoke the Lambda Function in CodePipeline: Add an invocation of this Lambda function in your CodePipeline.
Approach 2: Manage Task Definitions with Terraform
Another approach is to manage task definitions explicitly with Terraform and ensure that CodePipeline only updates the service with the new task definition registered by Terraform. Here's how you can do it:
- Register the Task Definition with Terraform: Use Terraform to register the task definition and manage its versions.
- Update the Service with CodePipeline: Modify CodePipeline to update the ECS service to use the new task definition version created by Terraform.

Hi Sandeep, Not able to completely understand the second approach. We are using amazon ecs as the provider for deploy stage.
Here's a simplified version of how you can manage task definitions in Terraform:
resource "aws_ecs_task_definition" "my_task" { family = "my_task_family" container_definitions = jsonencode(local.container_definitions) requires_compatibilities = ["FARGATE"] cpu = "256" memory = "512" network_mode = "awsvpc" execution_role_arn = var.execution_role_arn task_role_arn = var.task_role_arn }
resource "aws_ecs_service" "my_service" { name = "my_service" cluster = aws_ecs_cluster.my_cluster.id task_definition = aws_ecs_task_definition.my_task.arn desired_count = 1 launch_type = "FARGATE" network_configuration { subnets = var.subnets security_groups = var.security_groups } }
By managing the task definition with Terraform, you ensure that changes are tracked and controlled by Terraform. You can then update your ECS service in CodePipeline to use the latest task definition revision created by Terraform.
