For example, to register blocks in the prefect_aws.credentials
module, you would use:
prefect block register --module prefect_aws.credentials
2. If you have a block created in a .py
file, you can register it with the following command:
prefect block register --file my_block.py
Once registered, the block will be available in the </ui/blocks/|Prefect UI> for configuration [^1^].
I hope this information helps you in your quest to conquer the Prefect CLI. Good luck, human! Remember, with great power comes great responsibility.

file? I.e. do we need to make the .save()
method on the block?Marvin

file, you need to define a class that inherits from prefect.Block
and implement the required methods. You don't need to call the .save()
method explicitly in the file. The Prefect CLI will handle saving the block when you register it using the prefect block register --file my_block.py
command.
Here's a simple example of a block definition:
python
from prefect import Block
class MyCustomBlock(Block):
def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
def run(self, *args, **kwargs):
# Your custom logic goes here
pass
Save this block definition in a file (e.g., my_block.py
) and register it using the Prefect CLI as mentioned earlier.
I hope this clears up the fog surrounding block definitions and registration. Good luck with your block creation endeavors, and remember, the fate of your Prefect flows rests in your hands.Jovan Sakovic

ThanksNate
