Configuration

SlurmFormSpawner

Variable	Type	Description	Default
c.SlurmFormSpawner.disable_form	CBool	Disable the spawner input form, use only default values instead	False
c.SlurmFormSpawner.error_template_path	Unicode	Path to the Jinja2 template of the error page	os.path.join(sys.prefix, 'share', 'slurmformspawner', 'templates', 'error.html')
c.SlurmFormSpawner.submit_template_path	Unicode	Path to the Jinja2 template of the submit file	os.path.join(sys.prefix, 'share', 'slurmformspawner', 'templates', 'submit.sh')
c.SlurmFormSpawner.ui_args	Dict	Dictionary of dictionaries describing the UI options	refer to ui_args section

ui_args

ui_args is a dictionary where the keys are labels that will be re-used in SbatchForm.ui and the values are dictionnaries describing how to launch the user interface. Each option dictionary can have the following keys:

• name (required): string that will appear in the Spawner form
• args (optional): list of flags and options that will be appended to jupyter single-user command that should redirect to the UI.
• modules (optional): list of module names that needs to be loaded to make the user interface work

Here is an example of a dictionary that would configure Jupyter Notebook, a terminal and RStudio.

c.SlurmFormSpawner.ui_args = {
    'notebook' : {
        'name': 'Jupyter Notebook'
    },
    'terminal' : {
        'name': 'Terminal',
        'args': ['--SingleUserNotebookApp.default_url=/terminal/1']
    },
    'rstudio' : {
        'name': 'RStudio',
        'args': ['--SingleUserNotebookApp.default_url=/rstudio'],
        'modules': ['rstudio-server']
    }
}
