Limit resources in docker-compose v3
I was searching for this issue a while ago. I have found my answer here. At first, I tried to implement this functionality without using docker stack, but that did not work.
Here is the piece of code which you would use to limit container's CPU/memory consumption. For additional attributes, you can search the documentation of docker.
deploy: replicas: 5 resources: limits: cpus: "0.1" memory: 50M
Compose file does not recognize deploy attributes, unless you deploy the application as a stack.
you can try
docker-compose --compatibility up which is CLI flag that convert v3 files to their v2 equivalent, with deploy options translated when possible.
I was wondering the same thing and found this: https://github.com/docker/compose/issues/4513
So in short it's just not possible to do that, you have to use the version 2.1 of the docker-compose format to be able to specify limits that are not ignored by
