Based on the research, here's how you can set environment variables from a secret block in your

prefect.yaml

file for a

run_shell_script

step: 1. First, ensure you have created a Secret block in Prefect with your sensitive data. You can do this via the UI or using Python. 2. In your

prefect.yaml

, you can reference the secret in the

job_variables

section under the specific deployment. Here's an example:

yaml
deployments:
  - name: my-deployment
    job_variables:
      env:
        MY_SECRET_ENV: "{{ prefect.blocks.secret.my-secret-block-name.get() }}"
    work_pool:
      name: my-work-pool
    flow:
      path: ./flow.py

    # If using run_shell_script step
    actions:
      - name: run-my-script
        run_shell_script:
          script: ./my_script.sh
          env:
            SCRIPT_SECRET: "{{ prefect.blocks.secret.my-secret-block-name.get() }}"

There are two ways to handle this: 1. Global deployment level: Setting the environment variable in

job_variables.env

makes it available to all steps in the deployment 2. Step-specific level: Setting it directly in the

run_shell_script.env

section makes it available only to that specific step Important notes: - Replace

my-secret-block-name

with the actual name of your secret block - The secret value will be resolved at runtime - Make sure your worker has access to the secret block - You can reference multiple secrets by creating multiple environment variables If you need to reference an existing environment variable that's already set in your environment, you can use:

yaml
job_variables:
  env:
    MY_ENV_VAR: "{{ $EXISTING_ENV_VAR }}"

Would you like me to provide more specific examples or clarify any part of this explanation?
