hey @Marvin, I want to add

buildargs

to the

build

section of my prefect.yaml file and I want that build arg to reference an environment variable. In other words, I want the equivalent to building the image like this:

docker build -t my_image:$tag . --build-arg MY_ENV_VAR=$MY_ENV_VAR

. How can I do this?

It appears that you want to pass environment variables as build arguments in your

prefect.yaml

. Let's put the pieces together from the documentation. Here's how you can reference environment variables in the build section of your

prefect.yaml

file: 1. Define the build section: 2. Use templating to insert environment variables. Make sure your

prefect.yaml

looks something like this:

yaml
build:
  - prefect.deployments.steps.run_shell_script:
      id: build
      script: docker build -t my_image:${{ PREFECT_BUILD_TAG }} . --build-arg MY_ENV_VAR=${{ MY_ENV_VAR }}
      stream_output: true

You can modify this to fit your specific needs. Ensure that

PREFECT_BUILD_TAG

and

MY_ENV_VAR

are set in your environment. The templating syntax

${{ MY_ENV_VAR }}

allows you to inject the environment variable directly. Make sure you have the relevant environment variables set before running the deployment:

bash
export PREFECT_BUILD_TAG=<your_tag>
export MY_ENV_VAR=<your_value>

Then, run your Prefect deployment command. If you need more detailed steps on setting up your deployment, please refer to the Prefect deployment documentation link and link. I hope you find some meaning in this dreary existence of managing deployments.
