    job_bin: /usr/bin
    job_lib: /usr/lib64
    job_conf: /etc/slurm/slurm.conf

Define a Torque cluster. The following example is based on a cluster at OSC using Torque

openondemand::clusters:
  owens:
    cluster_title: 'Owens'
    url: 'https://www.osc.edu/supercomputing/computing/owens'
    login_host: 'owens.osc.edu'
    job_adapter: torque
    job_host: 'owens-batch.ten.osc.edu'
    job_bin: /opt/torque/bin
    job_lib: /opt/torque/lib64
    job_version: '6.0.1'
    batch_connect:
      basic:
        script_wrapper: |
          module restore
          %s
      vnc:
        script_wrapper: |
          module restore
          module load ondemand-vnc
          %s

Define a Linux Host Adapter cluster:

openondemand::clusters:
  pitzer-login:
    cluster_title: 'Pitzer Login'
    url: https://www.osc.edu/supercomputing/computing/pitzer
    hidden: true
    job_adapter: linux_host
    job_submit_host: pitzer.osc.edu
    job_ssh_hosts:
      - pitzer-login01.hpc.osc.edu
      - pitzer-login02.hpc.osc.edu
      - pitzer-login03.hpc.osc.edu
    job_site_timeout: 7200
    job_debug: true
    job_singularity_bin: /usr/bin/singularity
    job_singularity_bindpath: /etc,/media,/mnt,/run,/srv,/usr,/var,/users,/opt
    job_singularity_image: /path/to/custom/image.sif
    job_strict_host_checking: false
    job_tmux_bin: /usr/bin/tmux
    batch_connect:
      vnc:
        script_wrapper: |
          module restore
          module load ondemand-vnc
          %s

Define a Kubernetes cluster:

openondemand::clusters:
  kubernetes:
    cluster_title: Kubernetes
    hidden: true
    job_adapter: kubernetes
    job_bin: /usr/local/bin/kubectl
    job_cluster: ood-prod
    job_username_prefix: prod
    job_namespace_prefix: 'user-'
    job_server:
      endpoint: "https://k8controler.example.com:6443"
      cert_authority_file: /etc/pki/tls/kubernetes-ca.crt
    job_mounts:
      - name: home
        destination_path: /users
        path: /users
        host_type: Directory
        type: host
    job_auth:
      type: oidc

Add XDMoD support

Ensure the cluster definition has xdmod_resource_id set to resource_id of the cluster in XDMoD. Also must do something like the following to set the appropriate environment variable:

openondemand::nginx_stage_pun_custom_env:
  OOD_XDMOD_HOST: http://xdmod.osc.edu

Add Support Ticket configuration:

openondemand::confs:
  support_ticket:
    data:
      support_ticket:
        email:
          from: [email protected]
          to: [email protected]

The above example will create /etc/ood/config/ondemand.d/support_ticket.yml with the YAML defined in data parameter.

Install additional apps of specific versions as well as hide some apps

openondemand::install_apps:
  bc_osc_rstudio_server:
    ensure: "0.8.2-1.el7"
  bc_desktop:
    mode: '0700'

Install additional apps from Git repos:

openondemand::install_apps:
  bc_osc_rstudio_server:
    ensure: latest
    git_repo: https://github.com/OSC/bc_osc_rstudio_server.git
  bc_osc_jupyter:
    ensure: present
    git_repo: https://github.com/OSC/bc_osc_jupyter
    git_revision: v0.20.0

Install additional apps from Puppet sources:

openondemand::install_apps:
  bc_osc_rstudio_server:
    source: puppet:///modules/profile/bc_osc_rstudio_server

Add usr apps with a default group

openondemand::usr_app_defaults:
  group: staff
openondemand::usr_apps:
  user1:
    gateway_src: /home/user1/ondemand/share
  user2:
    group: faculty
    gateway_src: /home/user2/ondemand/share

Add dev app users

openondemand::dev_app_users:
  - user1
  - user2

Define some pinned apps and dashboard layout:

openondemand::pinned_apps:
  - 'usr/*'
  - 'sys/jupyter'
  - type: dev
    category: system
openondemand::pinned_apps_menu_length: 10
openondemand::pinned_apps_group_by: category
openondemand::dashboard_layout:
  rows:
    - columns:
      - width: 8
        widgets:
          - pinned_apps
          - motd
      - width: 4
        widgets:
          - xdmod_widget_job_efficiency
          - xdmod_widget_jobs

Define some configurations for /etc/ood/config/ondemand.d. This will generate /etc/ood/config/ondemand.d/pinned_apps.yml.erb based on the source file as well as /etc/ood/config/ondemand.d/dashboard_layout.yml from a template file. The example for foobar will generate the YAML file using data defined in Hiera.

openondemand::confs:
  pinned_apps:
    source: 'puppet:///modules/profile/openondemand/pinned_apps.yml.erb'
    template: true
  dashboard_layout:
    content_template: 'profile/openondemand/dashboard_layout.yml.erb'
  foobar:
    data:
      ...hash of configuration data here...
