@Marvin is there a way to load prefect secret blocks into environment varible of k8 deployment ?

To load Prefect secret blocks into environment variables in a Kubernetes deployment, you can use Kubernetes work pools to manage your deployment infrastructure. Here's a concise guide: 1. Create a Kubernetes Work Pool: - You can do this through the Prefect Cloud UI or Prefect CLI. - Navigate to the Work Pools tab and select Kubernetes as the work pool type. 2. Configure Environment Variables: - Within the work pool configuration, you can add environment variables. This can be done by specifying them in the job template or deployment configuration. - If you're using a Prefect-maintained image, you can add environment variables directly in the configuration. 3. Access Secret Blocks: - You'd typically access secret blocks in your flow code and then pass them as environment variables in your Kubernetes deployment configuration. For more detailed steps, you can refer to the Prefect Kubernetes Deployment Guide. The top-level API of Prefect includes functions like

flow

,

task

, and

deploy

, which are essential for defining and deploying flows. You might utilize these to programmatically define how secrets are accessed and passed to your Kubernetes environment. If you have more specific requirements or configurations, feel free to ask!

tldr, yes you can set

job_variables:
  env:
    SOME_ENV_VAR: "{{ prefect.blocks.secret.foo }}"

or instead using k8s secrets https://github.com/zzstoatzz/prefect-pack/blob/main/prefect.yaml#L66-L79

hell yee, thanks, exactly what I need 🙏

It seems like you're referring to a schema, but unfortunately, I don't have access to any specific schema or context above. If you can provide more details about the schema or the error you're encountering, I might be able to help. If your question is related to Prefect, please provide more context or details about what you're trying to achieve or the specific error message you're seeing.

@Marvin this simple list format does not work

job_variables:
            image: "{{ build-image.image }}"
            env:
              - name: ENV
                value: "stg"

Validation failed for field 'env'. Failure reason: [{'name': 'ENV', 'value': 'stg'}] is not valid under any of the given schemas"}

It looks like you're dealing with a YAML configuration issue, possibly related to a Prefect deployment or a similar system where YAML is used to define job configurations. The error message indicates that the format of the

env

field is not valid according to the expected schema. In many systems, environment variables are expected in a specific format. Commonly, they might be expected as a dictionary rather than a list of dictionaries. Here's a possible correction:

yaml
job_variables:
  image: "{{ build-image.image }}"
  env:
    ENV: "stg"

This format assumes that the system expects

env

as a dictionary mapping environment variable names to their values. However, if the system indeed expects a list of dictionaries, you might need to ensure that the schema or the validator is correctly set up to accept that format. If this is related to Prefect or a similar tool, please let me know, and I can look into the specific documentation or schema requirements for that tool.

@Marvin I need to extend it to use secret key ref, can you provide example where it is a list of dictionaries

To extend your YAML configuration to use a secret key reference in a list of dictionaries format, you might structure it like this:

yaml
job_variables:
  image: "{{ build-image.image }}"
  env:
    - name: ENV
      value: "stg"
    - name: SECRET_KEY
      valueFrom:
        secretKeyRef:
          name: my-secret
          key: secret-key

In this example: - The

env

field is a list of dictionaries, where each dictionary represents an environment variable. - The

SECRET_KEY

environment variable uses a

valueFrom

field to reference a secret key. -

secretKeyRef

specifies the secret's name and the key within that secret. This format is commonly used in Kubernetes configurations, where environment variables can be set from secrets. If you're using a specific platform or tool that requires a different format, please let me know, and I can adjust the example accordingly.

actually, make it a dictionary mapping instead, not a list of dictionary

Certainly! If you want to use a dictionary mapping for environment variables, including a secret key reference, it might look like this:

yaml
job_variables:
  image: "{{ build-image.image }}"
  env:
    ENV: "stg"
    SECRET_KEY:
      valueFrom:
        secretKeyRef:
          name: my-secret
          key: secret-key

In this configuration: -

env

is a dictionary where each key is the name of an environment variable. - The value for

SECRET_KEY

is a nested dictionary using

valueFrom

to specify the secret key reference. This format assumes that the system you're working with can interpret such a dictionary structure for environment variables. Adjustments may be needed based on the specific requirements or capabilities of the tool or platform you're using.
