Update the ECS Task Definition to Set PID Mode

Using the AWS CLI

1. Retrieve the existing task definition JSON

   aws ecs describe-task-definition \
       --task-definition {{family-or-full-arn}} \
       --query 'taskDefinition' > task-def.json

2. Edit task-def.json

   Locate the pidMode key and remove it, or set it to task.

   {
       "family": "{{my-task}}",
       ...
       "pidMode": "task", 
       ...
   }   

3. Register the updated task definition

   aws ecs register-task-definition --cli-input-json file://task-def.json

4. Update your ECS service to use the new task definition revision
