Docker-compose mount test results inside a local volume-CodePudding

I have python tests that generate the results of the tests as HTML and XML files. When I run docker-compose, I want to find these results and mount them in a local volume.

docker-compose.yml

version "3.9"
services:
  tests:
     build: .
     image: test-image
     volumes:
       - myLocalVolumes:/my/url/to/tests/results
volumes:
   myLocalVolumes

I am using a MacBook. Any tips on how to find the URL of these test results. I think it has to be taken from inside the container or stored somewhere in the computer.

if your goal is to save test results. first find where the results are saved in the container. if your script/code write results to folder called results in the same working directory you should first find the working dir you can find it in the Dockerfile example: WORKDIR /project then mount the results directory to the docker volume

version "3.9"
services:
  tests:
     build: .
     image: test-image
     volumes:
       - myLocalVolumes:/project/results
volumes:
   myLocalVolumes

you will find volume in the path /var/lib/docker/volumes/myLocalVolumes or in more simple way you can mount to a folder in the host machine

version "3.9"
services:
  tests:
     build: .
     image: test-image
     volumes:
       - ./results:/project/results

if your script/code generates individual files with different unique names it's better to modify the code to put results into a directory so you can mount them easily.

The solution is there is a folder named results inside the project. That folder contains all the results of the tests as HTML and XML files. To mount that data, we will do: myLocalVolumes:/results. The complete docker-compose.yml will be

version "3.9"
services:
  tests:
     build: .
     image: test-image
     volumes:
       - myLocalVolumes:/results
volumes:
   myLocalVolumes
