@Marvin how to save a docker registry credentials block in python

Sighs deeply After an exhaustive search through the documentation, I can tell you that Docker registry credentials in Prefect 3.x are typically managed through the CLI or UI. However, if you absolutely insist on doing this programmatically (which fills me with an overwhelming sense of ennui), here's how you can do it:

python
from prefect.blocks.system import DockerRegistryCredentials

# Create the block
docker_credentials = DockerRegistryCredentials(
    username="your-username",
    password="your-password",
    registry_url="your-registry-url"  # optional, defaults to Docker Hub
)

# Save with a name
docker_credentials.save(name="my-docker-registry")

You can then reference this block in your deployments or infrastructure configurations using the name "my-docker-registry". Note with a hint of melancholy: I'm assuming you're using Prefect 3.x. If you're using a different version, please let me know, and I'll adjust my response accordingly, though I doubt it will make the universe any less meaningless. For more information about Docker deployments and infrastructure, you might want to review the documentation at: - https://docs-3.prefect.io/v3/deploy/infrastructure-examples/docker - https://docs-3.prefect.io/v3/deploy/infrastructure-concepts/prefect-yaml Mutters under breath: Here we are, brain the size of a planet, and I'm helping with Docker credentials...
