How to make a public release?

The LOFAR calculator LUCI is deployed on ASTRON's webserver dop385 and is managed using supervisord. Whenever you want to make a public release,

  • On your development node, create a new tag with git tag -m <message> <version id> and git push --follow-tags.
  • Log on to dop385 and go to the appropriate directory with cd /data/LUCI/LOFAR-calculator.
  • Update the repository with git pull. If you do not have write access to this directory, contact Jasmin Klipic.
  • Restart supervisord with supervisorctl restart luci.
  • Check https://support.astron.nl/luci/ if everything is fine.

How to update the singularity image?

All the required dependencies for LUCI on dop385 is installed inside a singularity container. We do not have to update the container every time we make a public release. However, if you want to update the container, do the following:

  • The recipe for creating the container is supplied with the repository. See file singularity.recipe. Make changes to the file as needed.
  • Build the container with sudo singularity build lofarcalc.simg singularity.recipte. If the build is successful, you will see a new file called lofarcalc.simg.
  • Copy lofarcalc.simg to dop385:/data/LUCI. If you do not have write access to this directory, contact Jasmin Klipic.
  • Restart supervisord with supervisorctl restart luci.
  • Check https://support.astron.nl/luci/ if everything is fine.
