        To remediate the ECS Task Definitions having memory limit set in AWS Kubernetes using the AWS console, follow these steps:

        1. **Access AWS Management Console**: Go to the AWS Management Console ([https://console.aws.amazon.com/](https://console.aws.amazon.com/)).

        2. **Navigate to Amazon EKS**: Click on the "Services" dropdown menu at the top left corner of the AWS Management Console, then select "Elastic Kubernetes Service (EKS)" under the "Containers" category.

        3. **Select your EKS Cluster**: Click on the name of the EKS cluster where the ECS Task Definitions with memory limit set are located.

        4. **Navigate to the EKS Cluster**: In the EKS console, navigate to the "Workloads" section in the left-hand menu.

        5. **Select the Deployment**: Locate the deployment that corresponds to the ECS Task Definition with memory limit set, and click on it to view its details.

        6. **Edit the Deployment**: Click on the "Actions" dropdown menu and select "Edit".

        7. **Update the Memory Limit**: In the deployment configuration, locate the section where the memory limit is set. Remove or adjust the memory limit as needed to remediate the misconfiguration.

        8. **Save Changes**: After updating the memory limit, scroll down to the bottom of the page and click on the "Save" button to apply the changes.

        9. **Verify the Changes**: Once the changes are saved, monitor the deployment to ensure that the memory limit has been successfully remediated.

        By following these steps, you can remediate the ECS Task Definitions with memory limit set in AWS Kubernetes using the AWS console.

      <Accordion title="Using CLI">
        To remediate the ECS Task Definitions memory limit misconfiguration in AWS Kubernetes using AWS CLI, you can follow these steps:

        1. **Identify the ECS Task Definition**:
           * Use the AWS CLI command to list all ECS Task Definitions:
             ```bash theme={null}
             aws ecs list-task-definitions
             ```
           * Identify the Task Definition that has the memory limit set.

        2. **Update the ECS Task Definition**:
           * Use the `describe-task-definition` command to get the details of the Task Definition:
             ```bash theme={null}
             aws ecs describe-task-definition --task-definition <task-definition-arn>
             ```
           * Modify the Task Definition JSON file to remove the memory limit configuration.
           * Save the updated Task Definition JSON file.

        3. **Register the Updated Task Definition**:
           * Register the updated Task Definition using the `register-task-definition` command:
             ```bash theme={null}
             aws ecs register-task-definition --cli-input-json file://<path-to-updated-task-definition.json>
             ```

        4. **Update the ECS Service**:
           * Update the ECS Service to use the newly registered Task Definition:
             ```bash theme={null}
             aws ecs update-service --cluster <cluster-name> --service <service-name> --task-definition <updated-task-definition-family:revision>
             ```

        5. **Verify the Changes**:
           * Verify that the ECS Service has been updated successfully:
             ```bash theme={null}
             aws ecs describe-services --cluster <cluster-name> --services <service-name>
             ```

        By following these steps, you can remediate the ECS Task Definitions memory limit misconfiguration in AWS Kubernetes using AWS CLI.

      <Accordion title="Using Python">
        To remediate the ECS Task Definitions memory limit misconfiguration in AWS Kubernetes using Python, you can follow these steps:

        1. Install the AWS SDK for Python (Boto3) if you haven't already. You can install it using pip:
           ```
           pip install boto3
           ```

        2. Create a Python script to update the ECS Task Definition memory limit. Here is an example script:

        ```python theme={null}
        import boto3

        # Initialize the ECS client
        ecs_client = boto3.client('ecs')

        # Define the ECS cluster and task definition ARN
        cluster = 'your_cluster_name'
        task_definition_arn = 'your_task_definition_arn'

        # Get the existing task definition
        response = ecs_client.describe_task_definition(taskDefinition=task_definition_arn)
        task_definition = response['taskDefinition']

        # Update the memory limit in the task definition
        task_definition['containerDefinitions'][0]['memory'] = 512  # Set the desired memory limit in MB

        # Register the updated task definition
        new_task_definition = ecs_client.register_task_definition(
            family=task_definition['family'],
            containerDefinitions=task_definition['containerDefinitions']
        )

        # Update the ECS service to use the new task definition
        ecs_client.update_service(
            cluster=cluster,
            service='your_service_name',
            taskDefinition=new_task_definition['taskDefinition']['taskDefinitionArn']
        )

        print("ECS Task Definition memory limit updated successfully!")
        ```

        3. Replace `'your_cluster_name'`, `'your_task_definition_arn'`, and `'your_service_name'` with your actual ECS cluster name, task definition ARN, and service name respectively.

        4. Run the Python script to update the memory limit in the ECS Task Definition. This script will update the memory limit and then update the ECS service to use the new task definition with the updated memory limit.

        By following these steps, you can remediate the ECS Task Definitions memory limit misconfiguration in AWS Kubernetes using Python.

          # For Fargate you can also use per‑container memory but must still satisfy

              essential = true

              # HARD LIMIT (MiB) – REQUIRED BY THE CHECK
              memory = 512

              portMappings = [
                {
                  containerPort = 8080
                  hostPort      = 8080
                  protocol      = "tcp"
                }
              ]

              environment = [
                {
                  name  = "ENV_VAR_NAME"
                  value = "ENV_VAR_VALUE"
                }
              ]
            },
            {
              name      = "SIDE-CAR_CONTAINER_NAME"
              image     = "ACCOUNT_ID.dkr.ecr.REGION.amazonaws.com/OTHER_REPO:TAG"
              essential = false

              # HARD LIMIT (MiB) – ALSO REQUIRED HERE
              memory = 256
            }
          ])

          execution_role_arn = aws_iam_role.ECS_TASK_EXECUTION_ROLE.arn
          task_role_arn      = aws_iam_role.ECS_TASK_ROLE.arn
        }
        ```

        Substitute:

        * `TASK_DEFINITION_NAME` with a Terraform‑local name, e.g. `app_task`.
        * `TASK_DEFINITION_FAMILY` with your ECS task family name.
        * `PRIMARY_CONTAINER_NAME`, `SIDE-CAR_CONTAINER_NAME`, images, ports, env vars, and memory values (MiB) with what is appropriate for your workload.

        Changing `aws_ecs_task_definition` arguments always creates a new immutable task definition revision; existing revisions are not modified. You must then point any `aws_ecs_service` (or other callers) at the new revision (e.g., update `task_definition = aws_ecs_task_definition.TASK_DEFINITION_NAME.arn`).

        Verification: `terraform plan` should show a new revision for `aws_ecs_task_definition.TASK_DEFINITION_NAME` being created, with each container JSON now including `"memory": <value>`.
