Gitlab-ci: how to run python script with cl arguments

Question

I want to run a python script, which expects cl arguments, before the actual build, so I added the following piece in .gitlab-ci.yml:

.deploy_template: &template_name
  variables:
  - arg1: "https://some/url/"
  - arg2: "https://another/url/"
  - arg3: "https://one/more/url/"
  script:
  - python3 some/script/file.py $arg1 $arg2 $arg3

but I am getting the following error:

usage: file.py [-h] arg1 arg2 arg3

file.py: error: the following arguments are required: arg1 arg2 arg3

If the arguments are just strings (i.e. not variables), then it works fine, but it does not read the variables $arg1 etc.

In the gitlab docs it is mentioned, that I can use the bash syntax to supply variables, so $arg1 must the correct reference.

I use argparse in the script to get the cl arguments.

What is the correct way to call the variables in gitlab-ci.yml as the python script arguments?

Your variables is a list, but it requires a dictionary. Just remove the - from it.

.deploy_template: &template_name
  variables:
    arg1: "https://some/url/"
    arg2: "https://another/url/"
    arg3: "https://one/more/url/"
  script:
  - python3 some/script/file.py $arg1 $arg2 $arg3
