ansible setup.yml failed with error ''ansible_distribution' is undefined '

[parichehrvn]

Hi I want to install Openwhisk with docker using ansible. But when I run ansible-playbook -i environments/local setup.yml I get this error:

The conditional check 'nginx.ssl.cert == "openwhisk-server-cert.pem"' failed. The error was: error while evaluating conditional (nginx.ssl.cert == "openwhisk-server-cert.pem"): 'ansible_distribution' is undefined The error appears to have been in '/home/parichehr/openwhisk/ansible/setup.yml': line 60, column 5, but may be elsewhere in the file depending on the exact syntax problem. The offending line appears to be: # Generate nginx certificates - name: gen untrusted server certificate for host ^ here

As noted in slack, I think this is related to your ansible version being 2.5.2. Please try with ansible 2.7.7 or later.

I try with ansible 2.7.7 but I still get the same error. I try to modify setup.yml as follows:

- name: Setup.yml
  hosts: all
  gather_facts: yes

  tasks:
  ...........

and this error is solved but I get this error in TASK [gen untrusted client certificate for host]

I can confirm that I had the same exact issue, and updating the ansible from version 2.5.2 to 2.9.6 fixed the problem for me.

Tried with 2.12.4 and problem fixed.
