In ansible playbook docker parameter extra_host takes two parts host: ip_address. I am trying to pass the host and ipaddress in as variables. They are from prompt vars. The end result in my hosts file is: 1.2.3.4 {{server_hostname}}. Here is the code:

prompt: "Please enter the server IP address"
private: no

推荐答案
在你的任务之前使用 set_fact
制作 server_host_ip
dict:
Make server_host_ip
dict with set_fact
before your task:
- set_fact:
server_host_ip: "{'{{host_name}}':'{{host_ip}}'}"
并在 docker
模块中使用 {{server_host_ip}}
.
And use {{server_host_ip}}
in the docker
module.
