openwhisk ansible setup.yml失败，错误为“ ansible / _distribution未定义”

问题描述

我想使用 ansible 将 Openwhisk 与 docker 一起安装。但是当我跑步

ansible-playbook -i environments/local setup.yml

我收到此错误：

> 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   -

  hosts: all
  gather_facts: yes

  tasks:
