This project recreates the issues with layers disappearing from images when using the cache-from argument.
To recreate run the following steps:
DOCKER_BUILDKIT=1 docker build -t cgreening/cache_problem:1 . --build-arg BUILDKIT_INLINE_CACHE=1
docker push cgreening/cache_problem:1
docker run -it --entrypoint /bin/bash cgreening/cache_problem:1
root@f3b83bd929e6:/app# ls
Dockerfile README.md index.js node_modules package.json yarn.lock
Clean up just like on the build machine:
docker system prune -a
Build again
DOCKER_BUILDKIT=1 docker build -t cgreening/cache_problem:2 . --build-arg BUILDKIT_INLINE_CACHE=1 --cache-from cgreening/cache_problem:1
docker push cgreening/cache_problem:2
docker run -it --entrypoint /bin/bash cgreening/cache_problem:2
root@f3b83bd929e6:/app# ls
Dockerfile README.md index.js node_modules package.json yarn.lock
Clean up again:
docker system prune -a
Build again
DOCKER_BUILDKIT=1 docker build -t cgreening/cache_problem:3 . --build-arg BUILDKIT_INLINE_CACHE=1 --cache-from cgreening/cache_problem:2
docker push cgreening/cache_problem:3
docker run -it --entrypoint /bin/bash cgreening/cache_problem:3
root@462e81ea94e4:/app# ls
Dockerfile README.md index.js package.json
You will see that there is no node_modules folder. This folder should have been created by the step:
RUN yarn
