## Summary

[Amazon Elastic Container Service (ECS)](https://aws.amazon.com/ecs/) is a highly scalable, high-performance container orchestration service that supports Docker containers and allows you to easily run and scale containerized applications on AWS.
ECS is a widely used service in AWS.
But there is no Chaos Fault for ECS in Litmus ChaosHub.
So I want to add a new Chaos Fault for ECS.
Adding 'ecs task stop' Chaos Fault to Litmus ChaosHub can help create a more resilient system.

## Motivation

Litmus ChaosHub has plenty of Chaos Faults.
But there is no Chaos Fault for Amazon ECS.
ECS is a widely used service in AWS.
So I want to add a new Chaos Fault for ECS.
Adding 'ecs task stop' Chaos Fault to Litmus ChaosHub can help create a more resilient system.

### Goals

- Adding an 'ecs task stop' Chaos Fault to [Litmus ChaosHub](https://hub.litmuschaos.io/)
- Fixing [litmus-go](https://github.com/litmuschaos/litmus-go) and [chaos-charts](https://github.com/litmuschaos/chaos-charts) codes

### Non-Goals

- Fixing Litmus codes except for [litmus-go](https://github.com/litmuschaos/litmus-go) and [chaos-charts](https://github.com/litmuschaos/chaos-charts) is a non-goal

## Proposal

### Use Cases

#### Use case 1

In Chaos Studio, Users can select 'ecs task stop' Chaos Fault as part of the Chaos Experiment.
They can compose it with other Chaos Faults.

### Implementation Details

Here's a Chaos Fault Scenario.

![ecs-task-stop](./images/ecs-task-stop-fault-scenario.png)

#### Phase 1 - Add scenario to the litmus-go repository

I will use `litmuschaos/go-runner` image.
So I am going to add a new case in the litmus-go repository.

#### Phase 2 - Add a new Chaos Fault to the Litmus ChaosHub

After Phase 1 PR gets merged, I will raise a PR that adds an 'ecs task stop' Chaos Fault to the `chaos-charts` repository.
When all is done, the user can easily assault the ECS service.

## Risks and Mitigations

We need to grant proper RBAC permissions to the runner container.
Granting override permissions may affect other systems.

## Upgrade / Downgrade Strategy

## Drawbacks

## Alternatives
