问题很简单:Ansible中ansible_user
(前ansible_ssh_user
)和remote_user
之间有什么区别,除了第一个是配置文件,后者是在戏剧/角色中设置?它们如何与-u
/ --user
命令行选项相关?

它们似乎都是一样的。看看这里:
https://github.com/ansible/ansible/blob/c600ab81ee/lib/ansible/playbook/play_context.py#L46-L55
# the magic variable mapping dictionary below is used to translate
# host/inventory variables to fields in the PlayContext
# object. The dictionary values are tuples, to account for aliases
# in variable names.
MAGIC_VARIABLE_MAPPING = dict(
connection = ('ansible_connection',),
remote_addr = ('ansible_ssh_host', 'ansible_host'),
remote_user = ('ansible_ssh_user', 'ansible_user'),
port = ('ansible_ssh_port', 'ansible_port'),
此外,当我们想要在ansible主机文件中指定默认SSH用户时使用ansible_user
,其中 playbook 上下文中使用了remote_user
来自https://github.com/ansible/ansible/blob/c600ab81ee/docsite/rst/intro_inventory.rst
ansible_user 要使用的默认ssh用户名。
以下是在ansible_user
文件中使用ansible hosts
的示例:
[targets]
localhost ansible_connection=local
other1.example.com ansible_connection=ssh ansible_user=mpdehaan
other2.example.com ansible_connection=ssh ansible_user=mdehaan

remote_user和ansible_user之间的区别:
当您与剧本中的其他用户一起运行角色时,例如:
- name: Apply user configuration to user root
hosts: all
remote_user: root
- name: Apply user configuration to user murphy
hosts: all
remote_user: murphy
然后,您可以通过使用“ when:ansible_user == ..”而不是“ when:remote_user == ..”来为不同的用户执行条件任务。例如:
- name: Add user murphy to wheel group
user:
name: murphy
groups: wheel
append: yes
when: ansible_user == "root"
