Running docker compose using Docker-In-Docker, best practice

[RollsChris]

Hi,

I'm trying to open a project within a devcontainer using docker-compose.yml.

The project also contains a docker-compose.yml i want to up and down.

First i mount a license from my host into the devcontainer ( using the devcontainers docker-compose.yml), like so:

volumes:
      - ../:/workspaces/flowable-kickoff:cached
      - ../license:/home/vscode/license

then within the other docker-compose.yml used in the project i have:

volumes:
      - ~/license:/home/node/license:ro

But when i do this license it becomes a directory and not a file and everything fails.

What am i doing wrong.

Basically i'm trying to mount something into my devcontainer and then from there into another container..

Can anybody help

Thanks.

Any ideas anyone, its really starting to annoy me. It docker-outside-docker has to be used with host paths?
