AWS ChatBot not recognising ecs update-service command

Question

I am trying to create a command from Slack using AWS ChatBot that enables anyone in the channel to perform some AWS CLI commands, in this case it is ecs update-service. I've created an alias as follows

```
@aws alias create restart_service ecs update-service --cluster $cluster-name --service $service-name --force-new-deployment --region ap-southeast-2
```

Then, I was hoping that anyone that run this command
```
@aws run restart_service --cluster-name cluster-a --service-name service-a
```
will just right away execute the command and restart the service.

But instead, I received this message as if the AWS ChatBot doesn't understand the command
```
@slack-user - I'm not sure which AWS service or operation you meant by "ecs update-service --cluster cluster-a --service service-a --force-new-deployment --region ap-southeast-2".
Did you mean one of the following?
ecs update-service --service service-a cluster-a: Modifies the parameters of a service.
```

Is there any solution to this? Thanks!

Answer

Please review the following documentation 
[https://docs.aws.amazon.com/chatbot/latest/adminguide/chatbot-cli-commands.html]()

As a workaround, 
- you can Create a Lambda function and 
- Create an IAM role for your Lambda function with the necessary permissions to update the ECS service and then 
- Configure AWS ChatBot to allow invoking the Lambda function. This requires adding the necessary permissions to the AWS ChatBot IAM role. 
- Use AWS ChatBot to invoke the Lambda function from Slack, passing the required parameters like cluster-name and service-name.

like the following

```
@aws lambda invoke --function-name your_lambda_function_name --payload '{"cluster-name": "cluster-a", "service-name": "service-a"}'

```
