Convert Command To Subprocess

Question

I currently have the following:

tf = Terraform()
tf.init()
tf.plan(capture_output=False)
approve = {"auto-approve": True}
print(tf.apply(capture_output=False, auto_approve=True, skip_plan=True,**approve))

This works quite well, but I need to put it into a subprocess. I've tried the following:

tf = Terraform()
tf.init()
tf.plan(capture_output=False)
approve = {"auto-approve": True}
subprocess.check_output(['tf.apply','capture_output','0', 'auto_approve','1', 'skip_plan','1','**approve'])

However, I receive the error: "'tf.apply' is not recognised as an internal or external command, operable program or batch file."

Can I convert the above into a subprocess? And if so, how?

Answer 1

subprocess executes external commands. By contrast, you are trying to execute something like (but not quite) Python code. This fundamentally can't work.

What you can do is create a Python script that contains your Terraform code and execute that via subprocess.check_output . However, this only works if the Python script is complete . You can't jus execute a fragment as in your case.

For a minimal example of what you can do, take your original script, save it as tf.py and execute it like this in Python:

subprocess.check_output(['python', 'tf.py'])
