Having issues with Expect: module

I can’t seem to find much documentation or uses of this module. I tried reading up on pexpect documentation however, i’m unable to find my answer.

I’m having ansible run a script and then there are prompts that need to be answered.

`

  • name: GENERATE CERTIFICATE AND KEY
    expect:
    command: /home/user/script arg1
    chdir: /home/user/
    responses:
    (^)(?i)Enter: ‘{{ passphrase }}’
    (^)(?i)Verifying: ‘{{ passphrase }}’
    (^)(?i)Common: ‘{{ common_name }}’
    `

When the ./script runs, it has a series of text and the prompt finishes with:

‘Enter PEM pass phrase:’

is the (^)(?i) the correct regex I would be using to match the text ‘Enter’?

Id recommend just starting off with using `Enter: “{{ passphrase}}”

The (?i) indicates a case insensitive search, and the parents around ^ are unnecessary, and the can be problematic as sometimes expect sees a \n or a space as the first char.

Hi Matt - thanks for the quick response. That seemed to have done the trick.

Thanks!

Hi Matt,
Can you please help me here on “duplicate dict key”

The expect module has the ability to respond multiple times to a single expected string, so instead of defining the expected string 2 times, you define it once, but give it a list of responses. Such as:

  • expect:
    command: /usr/local/sbin/install_blade.sh
    responses:
    ‘(?i)Enter choice:’:
  • “2”
  • “99”
    ‘(?i)Enter desired hostname:’: “rhel72”
    ‘(?i)associate hostname with:’: “oambr-ext”

This will require that you are running ansible 2.1, since that is the first version to have the multi answers per question functionality.
