@Marvin Please show me how to use the from_source() and deploy() functions, and also with the pip_install_requirements() and clone() array passed to the “steps” argument.

It appears there's detailed documentation on how to use
from_source()
and
deploy()
functions, and how to configure the
steps
argument with
pip_install_requirements
and
clone
. ### Key Excerpts: - from_source function:
Copy code
python
  from prefect import flow
  from prefect.deployments import Deployment

  @flow
  def my_flow():
      print("Hello, Prefect!")
      
  Deployment.from_source(
      source="<https://github.com/prefecthq/demos.git>",
      entrypoint="repo_info.py:get_repo_info"
  ).deploy(
      name="my-first-deployment",
      work_pool_name="my-managed-pool",
  )
In the
from_source
method, you specify the source of your flow code. You can use various remote storage solutions such as GitHub, Docker images, AWS S3, etc. - deploy function:
Copy code
python
  Deployment.from_source(
      source="<https://github.com/prefecthq/demos.git>",
      entrypoint="repo_info.py:get_repo_info"
  ).deploy(
      name="my-first-deployment",
      work_pool_name="my-managed-pool",
  )
The
deploy
function is used to specify the deployment's name and the work pool. ### Using
steps
argument with
pip_install_requirements
and
clone
The
steps
argument can include actions like pip installation and cloning repositories. Here's an example deployment configuration in YAML:
Copy code
yaml
build:
  - requires: prefect
    function: clone
    arguments:
      repository: "<https://github.com/your-repo.git>"
  - requires: prefect
    function: pip_install_requirements
    arguments:
      file: "requirements.txt"
push:
  - requires: prefect
    function: pip_install_requirements
    arguments:
      file: "requirements.txt"
  - requires: prefect
    function: clone
    arguments:
      repository: "<https://github.com/your-repo.git>"
In the
deploy
mechanics, when you run
prefect deploy
in a directory containing
prefect.yaml
, steps are executed in order from
build
,
push
, and then
pull
sections. For additional details, refer to these sections of Prefect documentation: - Deployments - Deployment configuration If you need specific examples or further elaboration, feel free to ask!
