Ecs awsvpc networking enabled remediation

Using Console

Using CLI

To remediate the ECS tasks with incorrect network mode set to AWSVPC in AWS EKS (Kubernetes) using AWS CLI, you can follow these steps:

List the ECS tasks in your EKS cluster to identify the tasks with incorrect network mode:
```
aws ecs list-tasks --cluster <cluster-name> --query 'taskArns' --output text
```
Describe the ECS tasks to get more details about the tasks, including the network mode:
```
aws ecs describe-tasks --cluster <cluster-name> --tasks <task-arn>
```
Identify the tasks that have the network mode set to a value other than AWSVPC.
Update the ECS task definition to set the network mode to AWSVPC. You can do this by creating a new task definition revision with the correct network mode. You can use the sed command to update the existing task definition JSON file.

Update the task definition using the update-task-definition command:

aws ecs register-task-definition --cli-input-json file://<updated-task-definition.json>

Stop the existing tasks and start new tasks with the updated task definition:

aws ecs update-service --cluster <cluster-name> --service <service-name> --force-new-deployment

Verify that the new tasks are running with the correct network mode:

aws ecs describe-tasks --cluster <cluster-name> --tasks <new-task-arn>

By following these steps, you can remediate the ECS tasks with the incorrect network mode set to AWSVPC in AWS EKS using AWS CLI.

Using Python

To remediate the ECS tasks network mode misconfiguration in AWS Kubernetes using Python, you can follow these steps:

Use the AWS SDK for Python (Boto3) to interact with the AWS resources programmatically. Make sure you have the Boto3 library installed in your Python environment.
List all the ECS tasks in the AWS account using the list_tasks method from the ECS client in Boto3.
For each ECS task identified, describe the task using the describe_tasks method to retrieve the task definition ARN.
Retrieve the task definition using the describe_task_definition method to get the details of the task definition.
Check if the networkMode attribute in the task definition is set to awsvpc. If it’s not, update the task definition to set the networkMode to awsvpc.
Update the task definition using the register_task_definition method to apply the changes.

Here is a sample Python script to remediate the ECS tasks network mode misconfiguration:

import boto3

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

# List all ECS tasks
response = ecs_client.list_tasks()

for task_arn in response['taskArns']:
    # Describe the ECS task
    task_description = ecs_client.describe_tasks(
        cluster='your-cluster-name',
        tasks=[task_arn]
    )

    task_definition_arn = task_description['tasks'][0]['taskDefinitionArn']

    # Describe the task definition
    task_definition = ecs_client.describe_task_definition(
        taskDefinition=task_definition_arn
    )

    # Check if the network mode is set to AWSVPC
    if task_definition['taskDefinition']['networkMode'] != 'awsvpc':
        # Update the task definition
        task_definition['taskDefinition']['networkMode'] = 'awsvpc'

        # Register the updated task definition
        updated_task_definition = ecs_client.register_task_definition(
            family=task_definition['taskDefinition']['family'],
            containerDefinitions=task_definition['taskDefinition']['containerDefinitions'],
            networkMode='awsvpc'
        )

        print(f"Task definition {task_definition_arn} updated with network mode set to AWSVPC.")

Make sure to replace 'your-cluster-name' with the name of your ECS cluster. This script will identify ECS tasks with network mode misconfiguration and update them to use the awsvpc network mode.
