The problem wil solve it self as long as your ECS agent is cleaning up containers ever X time, but it means your daemon container will not be available until X time I'd like to work on the following feature: support multiple containers on the same EC2 instance exposing the same port to the outside world. This happens randomly with less than 1% of metrics. The plugin takes care of spinning up and shutting down EC2 instances based on the need of your deployment pipeline, thus removing bottlenecks and reducing the cost of your agent infrastructure. You're supposed to stop all tasks on a container instance before Expected Behavior. But, I looked up the information about the container instance on which you are facing this issue and it seems like it has a different agentHash than the one on the ecs-init is babysitting the ECS Agent container, and the ECS Agent container healthcheck (noted above) is focused solely on the health of the process and not the connection status. While running from the docker container B I am able to ping A with the FQDN but from the container A I am not able to ping B. 3, that do not recover on their own. For example, kms keys, s3 buckets, etc After bouncing the ecs agent, the role is applied and the container then has access.

In that scenario, you'll drain the instance, stop the Agent, update its config and reregister it to the new cluster Agent version: 1. If the ECS Agent times out waiting for container to be created and if the task is stopped and gets cleaned before docker daemon completes the container create operation, the container effectively gets orphaned from a cleanup perspective because ECS Agent thinks that it has already cleaned If not, it might be an issue with how ECS agent is being restarted. Environment Details De-registering is supposed to be final. We updated the ecs-agent version to 1. So for example: Instance has 4G memory My ECS instances are getting out of space very fast. In order to use this, you will need to be running a container instance with the newest agent release (1. The solution is flexible and provides simple settings for tweaking the behavior: Amazon Elastic Container Service Agent. In most cases it works well and ecs instance got registered. To let ECS Agent successfully register the external instance, the instance should not have a per-configured instance credential chain.
