How do I deploy updated Docker images to Amazon ECS tasks?

Question

What is the right approach to make my Amazon ECS tasks update their Docker images, once said images have been updated in the corresponding registry?

Answer 1

If your task is running under a service you can force a new deployment. This forces the task definition to be re-evaluated and the new container image to be pulled.

aws ecs update-service --cluster  --service  --force-new-deployment
