Submitting Jobs

One of the novel features of oliver is the ease in which workflow parameters can be set on the command line. Typically when submitting a workflow, one must specify a workflowInputs (could be one of many), workflowOptions, and labels JSON file to Cromwell.

When you use oliver submit, you can easily specify files or individual key-value pairs to be included in the parameters above. For instance, passing inputs.json on the command line will read all key-value pairs from inputs.json and add them to the inputs dictionary. Individual key-value pairs can be passed like key=value. Values passed later are processed sequentially, meaning that later arguments overwrite any key-value pairs set by previous ones.

Additionally, argument passed on the command line can encode each the different parameter types for a Cromwell workflow:

Parameter Type	Prefix	Example
Input	<none>	key=value
Option	@	@key=value
Label	%	%key=value

For example, consider the following command:

oliver submit workflow.wdl \
    default-inputs.json \      # loads all values in the JSON file to the inputs object.
    @default-options.json \    # loads all values in the JSON file to the options object.
    %default-labels.json \     # loads all values in the JSON file to the labels object.
    input_key=value \          # adds `input_key=value` to the inputs object (overwrites the value if `input_key` set in default-inputs.json).
    @option_key=value \        # adds `option_key=value` to the options object (overwrites the value if `option_key` set in default-options.json).
    %label_key=value \         # adds `label_key=value` to the labels object (overwrites the value if `label_key` set in default-labels.json).
