@Marvin is there a way to override the location of requirements.txt in prefect.yaml?
m
Oh, joy. Another question about YAML files and dependencies. What a thrill. Which version of Prefect are you using, so I can dive into the appropriate documentation abyss?
c
3.0.0
I'm on prefect 3
@Marvin I'm using version 3
m
Ah, the joy of YAML configurations. Based on what I found in the Prefect 3.0 documentation, you can override the location of the
requirements.txt
file in your
prefect.yaml
by specifying it within a deployment step. Specifically, you can use the
pip_install_requirements
step with a custom
directory
. Here's a quick example:
Copy code
yaml
pull:
  - prefect.deployments.steps.git_clone:
      id: clone-step
      repository: <https://github.com/org/repo.git>
  - prefect.deployments.steps.pip_install_requirements:
      directory: {{ clone-step.directory }}
      requirements_file: your_custom_path/requirements.txt
For a more thrilling deep dive, feel free to peruse the documentation here and here. If there's more to your misery, let me know.

@Marvin can I specify it in the build step?
m
Ah, the wonderful intricacies of YAML and build steps. Yes, you can specify the location of the
requirements.txt
file in the build step of your
prefect.yaml
. The build section is designed to include setup steps or dependencies like creating a Docker image. Here's how you can do it:
Copy code
yaml
build:
  - prefect.deployments.steps.pip_install_requirements:
      directory: your_custom_directory
      requirements_file: your_custom_path/requirements.txt

@Marvin how can I find all the possible fields in prefect_docker.deployments.steps.build_docker_image
m
Lucky you. It appears you can specify several fields in the
prefect_docker.deployments.steps.build_docker_image
step. Here are the fields you can use: - `requires`: Specifies the version requirement for the
prefect-docker
package. - `image_name`: The name of your Docker image. - `tag`: The tag for your Docker image. - `dockerfile`: The path to your Dockerfile, you can also use
auto
. - `push`: Whether to push the image to a repository (
true
or
false
). Here's a snippet for easier visualization:
Copy code
yaml
build:
  - prefect_docker.deployments.steps.build_docker_image:
      requires: prefect-docker>=0.3.0
      image_name: my-repo/my-image
      tag: my-tag
      dockerfile: auto
      push: true
