CLI Testing Scripts

The web UI enables you to easily write, upload and execute your own hardware testing scripts and see the results.

However, the MAAS CLI supports options not available from the web UI, including access to earlier versions of your scripts, script deletion and result automation.

To use the CLI, first make sure you are logged in.

Note: For further details on which metadata fields can be used within scripts, and what they do, see Commissioning and Hardware Testing Scripts.

Script management

To upload a hardware testing script to MAAS, enter the following:

maas $PROFILE node-scripts create name=$SCRIPT_NAME name> \
 script=$PATH_TO_SCRIPT type=testing

Changing the type to commissioning adds the test script to the commissioning process.

All uploaded scripts can be listed with the following command:

maas $PROFILE node-scripts read type=testing filters=$TAG

The optional filters argument lets you search for tags assigned to a script, such as using TAG=cpu with the above example.

A script's metadata, and even the script itself, can be updated from the command line:

maas $PROFILE node-script update \ 
 $SCRIPT_NAME script=$PATH_TO_SCRIPT comment=$COMMENT

The JSON formatted output to the above command will include 'history' dictionary entries for when the script was modified along with any comments for those modifications:

"history": [
    {
        "id": 40,
        "created": "Tue, 12 Sep 2017 12:12:08 -0000",
        "comment": "Updated version"
    },
    {
        "id": 34,
        "created": "Fri, 08 Sep 2017 17:07:46 -0000",
        "comment": null
    }
]

MAAS keeps a history of all uploaded script versions, allowing you to easily revert to a previous version using the id of the version you wish to revert to:

maas $PROFILE node-script revert $SCRIPT_NAME to=$VERSION_ID

Warning: The history for later modifications will be lost when reverting to an earlier version of the script.

To download a script, enter the following:

maas $PROFILE node-script download $SCRIPT_NAME > $LOCAL_FILENAME

To delete a script, use delete:

maas $PROFILE node-script delete $SCRIPT_NAME

Results

The command line allows you to not only view the current script's progress but also retrieve the verbatim output from any previous runs too.

If you only want to see the latest or currently running result you can use current-commissioning, current-testing, or current-installation instead of an id:

maas $PROFILE node-script-result read $SYSTEM_ID $RESULTS

You can also limit which results are returned by type (commissioning, testing, or installation), script name, or script run:

maas $PROFILE node-script-results read \ 
 $SYSTEM_ID type=$SCRIPT_TYPE filters=$SCRIPT_NAME,$TAGS

Finally, results can be downloaded, either to stdout, stderr, as combined output or as a tar.xz:

maas $PROFILE node-script-result download $SYSTEM_ID $RUN_ID output=all \
 filetype=tar.xz > $LOCAL_FILENAME

Note: $RUN_ID is labelled id in the verbose result output. See Determine a node's system ID for details on retrieving $SYSTEM_ID.
