Environment variable is not passed to the Python container action #134

Thank you for this course (and other ones as well). I've learned a ton from them.

The issue

While doing the course, I noticed that the Python Container Action does not print the expected output:

As evidence, I provide the Python Container Action jobs from this repo as well as my fork:

• this repo
• my fork

As you can see, both the output and the annotation are:

 Hello, World! Time is 20:57:54 UTC.

Instead of the expected (like with the other container actions):

Hello, from a container github action 👋! Time is 20:57:54 UTC.

The fix

In the 06-authoring-actions/container-actions/python-container-action/action.yaml I replaced args with env to properly pass the input environmental variable to the container:

  env:
    INPUT_WHO_TO_GREET: ${{ inputs.who-to-greet }}
  # # only needed when you want to use the positional arguments (sys.argv) in the Python script
  # args:
  #   - ${{ inputs.who-to-greet }}

It appears that the INPUT_WHO_TO_GREET is not injected automatically by GitHub, as you mentioned.

In the 06-authoring-actions/container-actions/shell-container-action/action.yaml, you can see that the INPUT_WHO_TO_GREET is populated manually.

Thank you again for the great courses you make!
