Enhancing CLI commands with new sub commands

[yottahmd]

We would like to enhance the CLI with new sub commands includes:

• delete <dag_name>
• ps [-d <dag_name>] [-r <run_id>]
• history [-d <dag_name>]
• delete-history <dag_name> [--older-than-days <n>]

Feedback & ideas from @ghansham

This is still a rough idea, so anyone feel free to suggest if there's more ideas or thoughts.

Updated spec

rm <options> <dag_name>
options can be:
-h: delete history
-d: delete dag yaml
-t: older than e.g. 10d (10 days), 24h (24 hours), etc. (default value can be globally configured and shown here)
-f: forced removal without interactive (default: false)
-i: interactive (default: true)

ps [-d <dag_name>] [-r <run_id>]

ls <options> <dagname pattern>
-n: next Run for cron jobs
-h: run history
-l: last run
-t: sorted by last run
-r: reverse

We can combine delete and delete-history into one:

rm <options> <dag_name>
options can be:
-h: delete history
-d: delete dag yaml
-t: older than e.g. 10d (10 days), 24h (24 hours), etc.  (default value can be globally configured and shown here)
-f: forced removal without interactive (default: false)
-i: interactive (default: true)

That's a nice idea. Thanks!

In delete I need a clean command which deletes all the underlying history data and logs corresponding to the dag.

[ghansham]

Following comand is proposed:

rm -dhf <dag_name>

See command options in the above messages for usage

[yottahmd]

Thanks a lot for ideas! Updated the spec in the first comment.

We can have another command:

ls <options> <dagname pattern>
-n: next Run for cron jobs
-h: run history
-l: last run
-t: sorted by last run time
-r: reverse

[yottahmd]

I like this idea!

[ghansham]

We propose one more command:

dagu showlog <dagname>/<runid/latest>

dagu showlog <dagname>/<runid/latest>/[<stepName>]

StepName is optional if not specified should show for all steps.

It is expected to run where the actual server is running.
