#6606 [Docs] Missing env setup in remote example Issue created by soyking ### Description In Running your workflow, commands for remote running missed env input, which cause remote error like:

File "/root/hello_world.py", line 19, in <module>
        registry=os.environ['FLYTE_IMAGE_REGISTRY']

This would work at my local machine:

FLYTE_IMAGE_REGISTRY=localhost:30000 pyflyte run --env FLYTE_IMAGE_REGISTRY=localhost:30000 --remote --project my-project --domain development hello_world.py hello_world_wf
