You can run the loader as a linux service so that it auto-starts when the machine boots up. This is outdated, the loader (daemon) runs in the container
Note, here are systemd scripts
Create a directory for the loader script, pid, and logs (feel free to change dir names etc). Note, in our case, the appserv dir is sync'ed across the cluster, the /opt/grouperLoader dir is not, so that is used for the pid and logs
| Code Block |
|---|
mkdir -p /opt/appserv/grouperLoader
mkdir -p /opt/grouperLoader
chown appadmin.users /opt/grouperLoader
|
...
Note, test the script as below, and make sure all the commands are in the right place, e.g. /bin/kill, /bin/ps, etc

#!/bin/bash
