How can I set a memory limit for an entire docker-compose stack?

Question

Besides setting a limit for each service (container) inside the docker-compose I'd love to know if there is any way to simply limit the memory the docker-compose stack has access to, similarly to the solution of every container but generalized for all the stack.

Answer 1

As of today, there's no "global stack" memory limit (or CPU limit) option with Docker Compose (or Compose Specs).

Instead, you can:

• Limit per containers as you already suggested
• Limit at Docker daemon level as per @Mihal By comment on question
