@Marvin have double curly braces inside base job template as part of a value

It appears you might be looking for guidance on using double curly braces inside a base job template as part of a value when working with Prefect work pools. While the search didn't return explicit information about the use of double curly braces, the base job template is essential for customizing worker behavior of flow runs within a work pool. A base job template includes a

job_configuration

section and a

variables

section, as outlined in the Prefect documentation. The

variables

section defines fields that can be customized per deployment and follows the OpenAPI specification. For more detailed information on the structure and customization options of base job templates, please refer to the following link: Concepts - Work Pools. The use of double curly braces usually implies templating, where you might be indicating a variable or placeholder to be replaced dynamically. If you need further assistance on a specific syntax within the base job template, you could provide more context, or we could search the Prefect community discussions or GitHub issues for related use cases.

@Marvin Have the double curly braces not part of a prefect variable templating and have them written plain

The search results don't seem to explicitly address how to include plain double curly braces, as in avoiding them being interpreted as templating syntax within Prefect templates. However, if Prefect is using standard Jinja templating or similar, as many templating engines do, you might be able to escape double curly braces by using an additional set of curly braces around them. For instance, you would write

{{ "{{}}" }}

to have

{{}}

appear as plain text rather than being interpreted as a template variable. Unfortunately, the Prefect documentation excerpts provided do not directly mention this particular case. To get a definitive answer, you might need to experiment with the templating syntax or consult the community for best practices regarding escaping characters within templates. For additional context, you might want to look into the following resource which further discusses developing a new worker type and uses the templating system: Developing a New Worker Type. However, please note that for specific escaping strategies, consulting the documentation of the underlying templating system or conducting some tests is often necessary.

@Marvin have double curly braces not as placeholder in prefect base job tempalte

The code example provided demonstrates templating within task names in Prefect, utilizing curly braces to embed variable values into the task name. However, this does not directly address your concern about including plain double curly braces, not as a placeholder, in a Prefect base job template. In general, templating languages like Jinja2 provide mechanisms to escape template syntax for situations where you want the curly braces to be treated literally rather than as delimiters for variables. Usually, this is done by doubling up the curly braces, as mentioned earlier. Here's how you might include plain double curly braces in a Jinja2 template (and likely in Prefect base job templates if they're similar):

{{ '{{}}' }}

The inner

{{}}

is treated as a literal string rather than a variable to be interpreted. Since the Prefect documentation or code examples do not provide this specific detail, I would suggest testing this approach in your Prefect base job template to verify if it works as intended. If you encounter any issues, looking into the community forums or GitHub may help to find if others have encountered and solved this issue. Remember to test in a controlled environment, so that if it doesn't go as expected—which wouldn't surprise me, given my vast knowledge of the universe and everything going wrong—there would be minimal impact.
