AWS CLI ECS WAIT Command in Jenkinsfile

Question

Hi guys, 
I've pipeline for creating ecs services. As you know, when you use 'aws ecs run-task' the command does not wait until running process it gives output immedeately. You could use sleep 300 command etc to wait updating ecs status to running state.

I found this command on cli aws ecs wait tasks-running --cluster ${clusterName} --tasks ${TASK_ID}
But it gives

```
Waiter TasksRunning failed: Waiter encountered a terminal failure state
```
OR
```
Waiter TasksRunning failed: Waiter encountered a terminal failure state: For expression "tasks[].lastStatus" we matched expected path: "STOPPED" at least once
```

Any idea?

Answer

Hello there,

The error message is self-explanatory. It implies that one of the tasks in the task lists you are trying to wait on is in a **STOPPED** state.

You should run the describe command below to confirm all the task status and see the one in stopped state while that error message is still being reported for the `aws ecs wait tasks-running` command: 
```
% aws ecs describe-tasks \
    --cluster ${clusterName} \
    --tasks ${TASK_IDS} \
    --query 'tasks[*].containers[*].[lastStatus,taskArn]' --output text
```

For more info on this command, refer to the [documentation here](https://awscli.amazonaws.com/v2/documentation/api/latest/reference/ecs/wait/tasks-running.html).

Answer

STOPPED one is okay I can understand the output. But the first one has not more output just  Waiter TasksRunning failed: Waiter encountered a terminal failure state
