Issue

Related to Issue BCLOUD-15844

I understand that the docker auth plugin is used to ensure that no directories above $BITBUCKET_CLONE_DIR are mounted for security reasons.
My issues is that no directories below $BITBUCKET_CLONE_DIR can be mounted either.

This bug started between 2018/06/08 and 2018/06/12

Usecase

I have two repositories:

1. Application source code.
2. Docker container for the application.

Pushing commits to the second repo should trigger a build of the image, clone the application source code down, mount to the container and run the tests, then push to dockerhub. My problem is that I can't clone the application source code directly to $BITBUCKET_CLONE_DIR because it's not empty (the docker files are there).

I can't include my docker image in the application repo, because if I rebuild and push the docker image for every single test of the application I'll run out of build minutes.

Error

This bug started between 2018/06/08 and 2018/06/12. The git clone step on the docker repo was actually working on 2018/06/08, mounting a directory below $BITBUCKET_CLONE_DIR. As of today (2018/06/12) it fails with this error:

docker: Error response from daemon: authorization denied by plugin pipelines: -v only supports $BITBUCKET_CLONE_DIR.

I have tried both -v $PWD/ApplicationSrc:/some/dir/on/docker and -v $BITBUCKET_CLONE_DIR/ApplicationSrc:/some/dir/on/docker both of which returned the same error.

I'd really appreciate if the auth plugin could be reverted to allow mounting of directories below $BITBUCKET_CLONE_DIR
