Configuring ECS task networking
Now that you have established networking infrastructure that will support the private IP addressing requirement of ECS task networking, you can proceed to configure ECS task networking on your ECS resources. This requires the following configurations and considerations:
- You must configure your ECS task definitions and ECS services to support ECS task networking.
- The network mode of your task definition must be set to
awsvpc
. - An elastic network interface used for ECS task networking can only have one ECS task associated with it. Depending on your ECS instance type, this will limit the maximum number of ECS tasks you can run in any given ECS container instance.
- Deployment of ECS tasks with ECS task-networking-configured takes longer than traditional ECS deployments, as an elastic network interface needs to be created and bound to your ECS container instance.
- Because your container applications have a dedicated network interface, dynamic port mapping is no longer...
