Aws ecs containers communication.

You can run your tasks and services on a serverless infrastructure that is managed by aws fargate or for more control over your infrastructure you can run your tasks and services on a cluster of amazon ec2. In this example my code in kcentral services can refer to rabbitmq container and it resolves fine. Tasks running on amazon ec2 container service amazon ecs can now take advantage of awsvpc mode for container networking. Ecs tasks enable you to manage containers and define communication between containers use task definitions to control images cpu memory links ports and iam roles use the new iam roles definition to isolate credentials and authorization between tasks.

Ecs is a great choice to run containers for several reasons. I created a single ecs cluster that has 2 services one for each of the above each with a task container.

Amazon elastic container service amazon ecs is a fully managed container orchestration service.

Highly secure reliable and scalable way to run containers. For containers there is a swappiness setting in the memory cgroup that allows you to control the swappiness of a container. This new mode allocates an elastic networking interface to each running task providing a dynamic private ip address and internal dns name. Amazon elastic container service amazon ecs is a highly scalable fast container management service that makes it easy to run stop and manage containers on a cluster.

It works by having an agent process run on each host instance which the central ecs controller service communicates with instructing the agent to spawn or kill specific containers as well as performing health checks on running containers.
