Is it possible to start a local execution from a launch plan

Question

Is it possible to start a local execution from a launch plan rather than directly invoking the workflow If so is there a documentation link for this

Rahul Mehta · Answer

For context we re trying to figure out how to get a tighter iteration loop when working on dynamic workflows it s been a bit onerous to actually need to run it in the cluster to debug and we can t take advantage of the full static type checking since we re using dynamic to specify launch plan dependent resource overrides

Ketan (kumare3) · Answer

you should be able to run dynamic locally as well right

Ketan (kumare3) · Answer

and ofcourse launchplans can be executed locally

Rahul Mehta · Answer

Is there an example of executing a launchplan locally in the docs would you be able to provide an example

Ketan (kumare3) · Answer

hmm

Rahul Mehta · Answer

I couldn t find anything when I looked recently but certainly could have missed something

```my fixed lp = LaunchPlan get or create name= always 2 lp workflow=my wf fixed inputs= val 2 square 2 = my fixed lp error square 1 = my fixed lp val=1 ```

Rahul Mehta · Answer

ah so `get or create` just returns a callable

Ketan (kumare3) · Answer

yup

Rahul Mehta · Answer

Cool Thanks will give this a try

Ketan (kumare3) · Answer

as you can even embed launchplans in workflows

Ketan (kumare3) · Answer

its like subworkflows

Ketan (kumare3) · Answer

and also call them locally

Rahul Mehta · Answer

oh I didn t realize that that s neat

Ketan (kumare3) · Answer

ohh man and you are still a power user haha

Ketan (kumare3) · Answer

please help improve docs

Ketan (kumare3) · Answer

cc < Niels Bantilan> < Samhita Alla> Rahul did not realize that you can run launchplans locally and also use it in workflows

Ketan (kumare3) · Answer

< Rahul Mehta> docs for external workflows

Rahul Mehta · Answer

This is really powerful we re going to bake this into our bazel target so users can run the workflow locally to test and then add the ` remote` flag to serialize deploy to the cluster

Rahul Mehta · Answer

Along with our typing improvements that solves most of our local devx concerns

< Samhita Alla> gonna fold this into the new getting started guide
