Hello everybody, I´ve played around with flyte on my local machine. Now I wanna run some simple (scheduled) workflows on my VPS. I am currently a little confused, on how to do that. Should I simply run a flyte demo cluster (

flyte demo start

) on my VPS?

you can certainly create a

flyte demo

cluster on your VPS and schedule workflows on there… @Yee @jeev is there any additional stuff to be aware of if you want to run a demo (sandbox) cluster in this fashion? you can also follow the single cluster deployment guide to create your own Flyte cluster (which cloud provider are you using?).

Thanks for the reply. My VPS is hosted by contabo.com. Additionally, I have a ARM virtual machine from oracles always free program. Can I run flyte on an ARM processor?

flyte demo start should get you up and going!

installed flyte on my arm virtual machine and got the following error, when running the example from here https://docs.flyte.org/projects/cookbook/en/latest/index.html

(flyte) ubuntu@instance-20230102-1221:~/dev/test_flyte$ pyflyte run example.py training_workflow \

i think that’s a python 3.11 issue. looks like we need some refactoring @Yee @Eduardo Apolinario (eapolinario) https://discuss.python.org/t/better-communicate-dataclass-mutable-default-check-change-in-python-3-11/19028

also worth noting that we're excluding python 3.11 in flytekit 1.3.2, while we work on https://github.com/flyteorg/flyte/issues/3312

Thanks. I´ll switch to python 3.10
