Switch from EKS to ECS, how to deal with shared docker volumes

Question

In our EKS world I use a pod with multiple container. Inside this I set a docker volume with
volumes:
- name: my-share
  emptyDir: {}

In each container defintion I use:

volumeMounts:
- name: my-share
  mountPath: /tmp

So that all container can share /tmp . 
How to deal with this in ECS with a multicontainer task definition?

Hi,

You can share EBS volumes or EFS across containers in ECS: see https://docs.aws.amazon.com/AmazonECS/latest/developerguide/ebs-volumes.html

The following article details how to share some EBS volumes across the various containers of an ECS task:  https://medium.com/@dipandergoyal/aws-ecs-sidecar-share-data-between-containers-16a992480cb

Best,

Hello Ognif,

A good shared storage solution in ECS is either EFS or Amazon FSx for Windows File Server, or Bind mounts. Refer this AWS Documentation for more https://docs.aws.amazon.com/AmazonECS/latest/developerguide/using_data_volumes.html
