When using

flytectl

, there are a few options around archiving/activating launchplans. I have been looking to move our wrapping code around launchplans to use

flytekit

, but I'm not seeing corresponding options. As far as I can tell, the

LaunchPlan.get_or_create

function just creates the object, but does not activate it. Am I missing something?

we don’t support archiving/activating LP for now. would you mind creating an issue for it. [flyte-core]

For sure

@Kevin Su, it should be possible to activate a launchplan with pyflyte, correct? https://github.com/flyteorg/flytekit/pull/1588

Sorry. I forgot we already support that. @Samhita Alla Thanks for the reminder. @Sam Eckert could you give it a try

Correct me if I am wrong, but that would still require calling out to a CLI right? What’s the benefit of using pyflyte here instead of flytectl?

pyflyte can serialize the workflow, but flytectl can’t. if only want to serialize/register/run the workflow. you can just use pyflyte. if you want to use sandbox or update some resource (task resource, execution label, etc), you have to install flytectl

Also if you want to activate the launch plan at the API level, you can use FlyteRemote. Take a look at the following code that activates a launch plan: https://github.com/flyteorg/flytekit/blob/3b064dca90de2d0d2d691e931aaadca56beb3a7f/flytekit/clis/sdk_in_container/launchplan.py#L61-L68.

This should work! Thanks.

You don't have to manually deactivate old launch plans. When you activate the new version of a launch plan, all the old ones will be automatically deactivated.

Oh interesting. I think I ran the equivalent of

flytectl get launchplan -p flytesnacks -d development -o yaml  --filter.fieldSelector "state=1"

(from https://docs.flyte.org/projects/flytectl/en/latest/gen/flytectl_get_launchplan.html) but with a name parameter, and got multiple launchplans back. It is possible the name param was ignored and I accidentally disabled every launchplan across the project/domain...

Oh multiple active launch plans?

Yeah, thats what I was seeing. Let me test on my end to see if I can reproduce
