→Running Daemons: apptainer instance
| Line 199: | Line 199: | ||
Apptainer has been designed to be able to properly run daemons within compute jobs on clusters. Running daemons is achieved, in part, by using <code>apptainer instance</code>. See the [http://apptainer.org/docs/user/main/running_services.html official Apptainer documentation on Running Services] for the details. | Apptainer has been designed to be able to properly run daemons within compute jobs on clusters.

'''NOTE:''' Don't run daemons manually without using <code>apptainer instance</code> and related commands. Apptainer works properly with other tools such as the Slurm scheduler that run on our computer clusters. When a job is cancelled, killed, crashes, or is otherwise finished, daemons run using <code>apptainer instance</code> will not hang or result in defunct processes. Additionally by using the <code>apptainer instance</code> command you will be able to control the daemons and programs running in the same container. | '''NOTE 1:''' Don't run daemons manually without using <code>apptainer instance</code> and related commands.

'''NOTE 2:''' Running daemons in your job will only run while your job runs. The scheduler will kill all processes attached to a job when the granted job time expires. If you need to run daemons continuously for longer than a job, submit a ticket asking to discuss such with staff persons. | |||
