How to let ansible answer "yes" to everything sendmailconfig asks
提问by kramer65
I'm setting up a server with ansible, and I want to install and configure sendmail. To do this I first install it using apt, and then I need to run sendmailconfigAND asnwer yto all the questions it asks.
我正在使用 ansible 设置服务器，并且我想安装和配置sendmail. 为此，我首先使用 apt 安装它，然后我需要运行sendmailconfigANDy回答它提出的所有问题。
That last part is the hardest I think. sendmailconfigdoesn't have a -yflag to answer yes to everything, so how do I get Ansible to simple agree to all questions it asks?
最后一部分是我认为最难的。sendmailconfig没有一个-y标志来回答所有的问题，那么我如何让 Ansible 简单地同意它提出的所有问题？

Basically, you would need to perform two tasks: update hosts and run sendmailconfig. Note: If you are running Ansible 2.5.0 you might need to install the pexpect module on the remote host, so include this task into your tasks file. For example:
基本上，您需要执行两项任务：更新主机和运行 sendmailconfig。注意：如果您运行的是 Ansible 2.5.0，您可能需要在远程主机上安装 pexpect 模块，因此请将此任务包含在您的任务文件中。例如：
- name: Update hosts
lineinfile:
path: /etc/hosts
regexp: '^127\.0\.0\.1'
line: '127.0.0.1 localhost {{ ansible_host }}'
owner: root
group: root
mode: 0644
- name: Install pexpect module
raw: sudo apt-get -y install python-pexpect
- name: Configure sendmail
expect:
command: sendmailconfig
responses:
Question:
- Configure sendmail with the existing /etc/mail/sendmail.conf? [Y]: y
- Configure sendmail with the existing /etc/mail/sendmail.mc? [Y]: y
- Reload the running sendmail now with the new configuration? [Y]: y
timeout: 30
