How to access the file generated inside docker container by defining the volume in docker-compose.yml file

Question

I am rookie when it comes to docker container , can somebody help me here.

There is a project which generates a output files when running inside docker container , I need to add Volume inside docker-compose.yml file, So that the output files are accessible outside the container .

Please do provide me indetail knowledge of how can I do this?

Answer 1

Define volumes in the docker-compose.yml file, mapping source on the server to target in the container:

volumes:
  - "./relative/path/on/host:/absolute/path/in/container:rw"

Reference:

https://docs.docker.com/storage/volumes/#use-a-volume-with-docker-compose

There hopefully should be a readme.md file in the project which lists the options on how to get the output (files).
