The
swagger.json/Gemfile.lockfiles generated inside of the test-app are created by the docker user. The docker user is root by default. When using docker-compose volumes to share files between the host & the container, the generated file retains the root docker user as the owner. This prevents any edits from being made to those files locally without using eithersudoorsudo chown.The solution is to set the container user id to match your own user id. Typically you'll be
USER_ID=1000on your own machine, and you can double check that using$ id -u.If your user id differs, then
docker build --build-arg USER_ID=$(id -u) .will pass your id into the docker container build.
