通过以上步骤,我们就成功地实现了在Kubernetes环境中使用Ansible工具并通过"ansible --list-hosts"命令列出所有主机的操作。 在这个过程中,主要用到的是Ansible配置文件(ansible.cfg)、主机清单文件(inventory)以及Ansible命令(ansible --list-hosts)。可以根据需要对Ansible进行更多配置,比如添加SSH密钥等,以便更好地管理...

其实我上面说的功能,已经算是可以实现动态的hosts功能,看了沈灿和金山小伙的晓聪的讨论,才知道有个叫 Dynamic Inventory 的东西,这个功能其实是我上面讲解第二个方法的集成版,他省略了这一步,直接调用一个有inventory功能的脚本,然后取出相关的主机list,然后执行。
1、正常写法,name1为别名： [test1] name1 ansible_ssh_host=192.168.1.111 ansible_ssh_user=...
