Ansible stat模块不工作
Ansible stat模块不工作
提问于 2017-01-27 15:02:38
我需要一些帮助：
我正在使用Vagrant创建虚拟机，以便在它们上配置一些集群。对于我想用作Ansible控制节点的第一个VM，我从本地机器运行Ansible，以便在我的control node中安装和配置Ansible。
当我尝试检查.inventory文件是否存在并尝试将该文件复制到主目录(在虚拟机中)时出现问题。
我对清单文件使用的命令只适用于检查.ansible.cfg文件的状态，而不是清单文件的状态。
你们知道我做错了什么吗？

inventory_file是一个magic variable，由Ansible在playbook运行期间设置，覆盖您尝试分配的任何值。
在inventory stat任务中，您可能会注意到：invocation.module_args.path: null。
将您的inventory_file变量重命名为my_inventory_file，它将起作用。

copy发现文件已经存在，并表示没有更改，但与您的源文件相同，不做任何更改。
调试输出显示：
stat_ansible_config.stat.exists = True
stat_inventory.stat.exists = False这就解释了行为上的差异。
