the cause of the error - empty dir /usr/share/nailgun/static/ in fuel-core-8.0-nailgun container

[Dmitry Teselkin (teselkin-d)]

The reason why that folder is empty is because it becomes 'masked' by volume from the host system.

There are two possible ways to solve is:
1. Make fuel-nailgun package available on master node from inside the container
2. During container image build, as the last step create a .tar.gz archive of /usr/share/nailgun/static/ somewhere in the container. Add some logic to 'start.sh' that will check that this folder contains required files when container is started, and if the directory is empty or misses some key files - restore from archive.

It is blocker for verification bugs with UI used.

Is some workaround available?

    Unmount volume before puppet install fuel-nailgun package

    During build of the container image, puppet apply the manifest in
    container with the already mounted external volumes, as the
    result that some of the files are not saved in the container image
