Replacing cubied with run-cvmfs.sh (issue #20)

[kreczko]

PR regarding issue #20

• removed all traces of cubied
• modified run-cvmfs.sh to execute the CMD
• changed ENTRYPOINT cubied → run-cvmfs.sh

Tested with

docker build -t hepsw/cvmfs-base .
docker run --privileged -ti hepsw/cvmfs-base ls -l /cvmfs/sft.cern.ch/lcg/

ah. well, cubied is still needed (so it can properly act as a mini PID 1 process, reaping zombies and such).

wouldn't it work with adding another shell script (so it doesn't confuse gitlab-runner) that runs cubied ?

[kreczko]

At the moment everything you run in the container is encapsulated in cubied, e.g.

#!/usr/bin/cubied

echo "::: cvmfs-config..."
cvmfs_config setup || exit 1

echo "::: mounting FUSE..."
mount -a
echo "::: mounting FUSE... [done]"

exec "$@"

This includes the gitlab-runner shell check:
https://gitlab.com/gitlab-org/gitlab-ci-multi-runner/blob/master/shells/bash.go

Unless the gitlab-runner is able to resolve cubied, I don't think there is a better workaround.

That said, our CI container (cvmfs-base →cvmfs-lz →lz-builder) is independent of this PR, so there is no need to merge until we find a better solution.
