Draft: feat: update RunApplication to provide a container to RemoteRunner

Alexandre Franck Boyer requested to merge alboyer/LHCbDIRAC:feat_RunApplication-container-images into master

Needs https://github.com/DIRACGrid/DIRAC/pull/7536

Just in case you would think of any more elegant solution, I also tried the following approaches:

  • Starting lb-prod-run from the cvm4 container. It fails with:
> singularity exec --bind cvmfs/:/cvmfs cvm4.sif bash
Singularity> singularity exec /cvmfs/lhcb.cern.ch/containers/os-base/slc6-devel/prod/amd64 ls
ERROR  : Failed to set effective UID to 0

export SINGULARITY_TMPDIR=</a/path/to/tmp>
> singularity exec --userns --bind cvmfs/:/cvmfs cvm4.sif bash
INFO:    Converting SIF file to temporary sandbox...
FATAL:   while extracting cvm4.sif: root filesystem extraction failed: could not create /a/path/to/tmp/rootfs-842229901/root/dev: mkdir /a/path/to/tmp/rootfs-842229901/root/dev: permission denied
  • Starting lb-prod-run from bare metal using the cvmfs directory available on the remote host. I quickly got some issues as /cvmfs is hardcoded in many different places.
