@Marvin - does the work pool advanced templates support syntax for referencing blocks/environment variables stored in prefect?

Prefect's work pool advanced templates do support syntax for referencing variables, which can include environment variables. The base job template in a work pool can be customized to include placeholders using double curly braces (

{{ }}

). These placeholders can reference values defined in the template's

variables

section, which are customizable per deployment or flow run. However, referencing Prefect blocks directly in these templates is not explicitly mentioned in the documentation. You might need to handle block references programmatically in your flow or deployment setup. For more details, you can refer to the Prefect documentation on work pools.

@Marvin so i could provide the syntax "{{ prefect.blocks.docker-registry-credentials.dev-registry }}"

The syntax

{{ prefect.blocks.docker-registry-credentials.dev-registry }}

is not directly supported for referencing Prefect blocks within work pool templates. The placeholders in work pool templates are typically used for variables defined within the template itself, not for dynamically accessing Prefect blocks. To use Prefect blocks, you would typically retrieve them within your flow code or deployment setup using Prefect's Python API and then pass the necessary values into your work pool configuration. For example, you might retrieve a block in your flow like this:

python
from prefect.blocks.system import Secret

# Retrieve a secret block
docker_credentials = Secret.load("docker-registry-credentials-dev-registry")

Then, use these credentials in your flow or deployment logic as needed. For more detailed guidance, you might need to manually handle the integration between Prefect blocks and your deployment configurations.
