The Jobbergate Agent Snap deploys the Jobbergate Agent Python package on your host system. This agent is an essencial component of the Jobbergate platform for managing and submitting jobs to HPC clusters.
This snap requires a few configuration values to be set before it can be used. These values are:
base-api-url: The URL of the Jobbergate API server where the agent will send its data. Setting/unsetting this value is more interesting when using the snap in a development environment; do not change it otherwise.
oidc-domain: The domain of the OIDC server that the agent will use for authentication. Setting/unsetting this value is more interesting when using the snap in a development environment; do not change it otherwise.
oidc-client-id: The client ID of the OIDC application that the agent will use for authentication.
oidc-client-secret: The client secret of the OIDC application that the agent will use for authentication.
task-jobs-interval-seconds: The interval in seconds at which the agent will run its internal task jobs, hence sending data to the Jobbergate API server. This is optional and defaults to 30 seconds.
task-self-update-interval-seconds: The interval in seconds at which the agent will check for updates to itself. This is optional and defaults to 30 seconds (1 hour).
sbatch-path: The absolute path to the sbatch command on the host system. This is optional and defaults to /usr/bin/sbatch.
scontrol-path: The absolute path to the scontrol command on the host system. This is optional and defaults to /usr/bin/scontrol.
default-slurm-work-dir: The default working directory that the agent will use when submitting jobs to the SLURM cluster. This is optional and defaults to /tmp.
slurm-user-mapper: The user mapper that the agent will use to map the system user name to the SLURM user name. This is optional and defaults to none.
single-user-submitter: The system user name that the agent will use to submit jobs to the SLURM cluster on behalf of in case the single-user-submitter is not set. This is optional and defaults to ubuntu.
write-submission-files: A boolean value (true, false) that indicates whether the agent should write submission files to disk. This is optional and defaults to false.

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
Snap is available for Red Hat Enterprise Linux (RHEL) 8 and RHEL 7, from the 7.6 release onward.
The packages for RHEL 7, RHEL 8, and RHEL 9 are in each distribution’s respective Extra Packages for Enterprise Linux (EPEL) repository. The instructions for adding this repository diverge slightly between RHEL 7, RHEL 8 and RHEL 9, which is why they’re listed separately below.
The EPEL repository can be added to RHEL 9 with the following command:
sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm
sudo dnf upgrade
The EPEL repository can be added to RHEL 8 with the following command:
sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
sudo dnf upgrade
The EPEL repository can be added to RHEL 7 with the following command:
sudo rpm -ivh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
Adding the optional and extras repositories is also recommended:
sudo subscription-manager repos --enable "rhel-*-optional-rpms" --enable "rhel-*-extras-rpms"
sudo yum update
Snap can now be installed as follows:
sudo yum install snapd
Once installed, the systemd unit that manages the main snap communication socket needs to be enabled:
sudo systemctl enable --now snapd.socket
To enable classic snap support, enter the following to create a symbolic link between /var/lib/snapd/snap and /snap:
sudo ln -s /var/lib/snapd/snap /snap
Either log out and back in again or restart your system to ensure snap’s paths are updated correctly.
To install jobbergate-agent, simply use the following command:
sudo snap install jobbergate-agent --classic
Browse and find snaps from the convenience of your desktop using the snap store snap.
