Why is the Amazon ECS container instance that I terminated still registered with its cluster?
Last updated: 2022-02-22
I terminated my container instance in Amazon Elastic Container Service (Amazon ECS), but my container instance still appears as a resource in my Amazon ECS cluster. How can I remove this container instance from my cluster?
If you terminate a RUNNING container instance with a connected Amazon ECS container agent, the agent automatically deregisters the instance from your cluster. However, if you terminate a STOPPED container instance with disconnected agents, the container instance isn't automatically removed from the cluster.
The deregistered container instance will no longer appear as a resource in your Amazon ECS cluster.
