Directory layout should be as follows:

• opencv/ - opencv sources
• opencv_extra/ - opencv test data
• <this_repository>/
  • workspace/ - directory with opencv builds and caches
  • scripts/ - directory with build and test scripts
  • ...
  • run.sh - entrypoint script

Steps:

1. ./run.sh - will build docker image and run the container
2. Inside the container: build.sh - build opencv
3. Inside the container: test.sh - run tests

Modify scripts in the scripts/ directory according to your needs.
