Automating the Install

The general process of automating the install proceeds like this:

1. A cron job (or similar) runs periodically and launches a script which examines current tags of soconda and finds the latest one. It looks at the installation directory and determines whether this tag has been installed. If not, it runs an installation wrapper script for the current system.

2. The wrapper script has hard-coded paths to the various locations and also knows how to build the version string to use. This script calls the soconda.sh script to install the latest tag.

3. If a new tag was installed, a message is posted via slack hook to one of the Simons Observatory slack channels.

Example: Perlmutter at NERSC

In the deploy subdirectory are the relevant files. The perlmutter install wrapper script is in install_perlmutter.sh. The tag checking script run by the cron job is in install_nersc_tag.sh, and the example lines in the scron tab are in scron_check_tag.slurm.
