Running ECS task in boto3

Question

I have created an image in ECR, a Task Definition, and Cluster. I successfully ran a task using the console but no luck using boto3.
The status of the task is stuck at **PENDING** and no logs were generated.
Here's my code:

```python
client = boto3.client('ecs')
overrides = {
    'containerOverrides': [
        {
            'name': 'my-container'   
        }
    ]
}
client.run_task(
	taskDefinition=JOB_DEFINITION_ARN,
   	cluster=JOB_CLUSTER_ARN,
    count=1,
    launchType='FARGATE',
    platformVersion='LATEST',
    networkConfiguration={
        'awsvpcConfiguration': {
            'subnets': SUBNETS,
            'securityGroups': [
                SEC_GROUP
            ],
            'assignPublicIp': 'DISABLED',
        }
    },
    overrides=overrides,
)
```

How can I properly run my task using boto3?

Hi,

The section "cluster examples" of https://docs.aws.amazon.com/AmazonECS/latest/developerguide/security_iam_id-based-policy-examples.html will provide with examples of various IAM policies to execute various ECS under your IAM role.

You can copy those policies and adapt them to your specific use case with the actions that you need to do from boto3.

Best,

Didier

Hi Vince,

Please ensure that the **IAM role which you are using has the necessary permissions to run tasks on ECS**, describe task definitions, and other relevant actions.
