how to attach a EBS volume to my container using docker-compose.yml and ecs-cli
I am using
docker-compose.yml to define a set of containers. And use
ecs-cli compose (service) up to create my application on
AWS ECS comes with 100GB
EBS automatically when a container is created. (Even though the
EC2 instance that hosts the container only have 8GB of hard drive.)
I want to have a persistent storage so that even if I updated my container, it can still point to the same 100GB
EBS. I am pretty sure I can do the following to achieve this goal:
Attach an external
EBSto the EC2 instance, and use
compose file to attach that volume to the container.
However, I feel there might be a better way to do so on ECS since it gives you 100GB ELB automatically. That is, if I use the above approach, then I am really ‘wasting’ the 100GB volume that comes with each container.
So, what is the best way to achieve this. Could you give an answer in the form of a docker-compose.yml format like the following?
container1: image: image1 container2: image: image2 links: - "container1"
