YAML库存解析

Question

hosts.ini

[local]
127.0.0.1 ansible_connection=local

hosts.yaml

^{pr2}$

然后我运行ansible local -m ping -i hosts.ini得到预期输出，然后运行ansible local -m ping -i hosts.yaml得到：

[WARNING]:  * Failed to parse /home/elruso/projects/ansible/hosts.yaml with ini plugin: /home/elruso/projects/ansible/hosts.yaml:5: Expected key=value host variable assignment, got: local
[WARNING]: Unable to parse /home/elruso/projects/ansible/hosts.yaml as an inventory source
[WARNING]: No inventory was parsed, only implicit localhost is available
[WARNING]: Could not match supplied host pattern, ignoring: local
[WARNING]: No hosts matched, nothing to do

根据docs的说法，我可以毫无问题地使用yaml文件作为库存。如何指定使用yml插件？在

$ansible --version
ansible 2.4.0.0
config file = /home/elruso/projects/ansible/ansible.cfg
configured module search path = ['/home/elruso/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
ansible python module location = /home/elruso/.virtualenvs/ansible/lib/python3.6/site-packages/ansible
executable location = /home/elruso/.virtualenvs/ansible/bin/ansible
python version = 3.6.2 (default, Jul 20 2017, 08:43:29) [GCC 5.4.1 20170519]

Answer 1

这个问题在python3中是可重现的，看起来像一个bug。在

使用python2而不是python3，因为后者是not officially supported yet。在

Answer 2

python3上的ansible2.4.0中有一个bug（试图在字符串列表中找到.yml字节）。在

此错误已在提交https://github.com/ansible/ansible/commit/72bdf7aa7e1b867380201092dff65338d59cd8fa中修复，它可能会作为2.4.1发布。在
