有没有办法遍历ansible字典来分配其他ansible字典值?
我的group_vars / all中包含以下内容:
domain_controllers:
dc0:
hostname: "dc0"
ip_address: "192.168.1.0"
dc1:
hostname: "dc1"
ip_address: "192.168.1.1"
dc2:
hostanme: "dc2"
ip_address: "192.168.1.2"
我有一个通用的keepalived角色,该角色将keepalived配置为服务器角色用来为这些域控制器制作VIP。
以下是我的roles/servers/forward/vars.yml
,keepalived角色用来构建keepalived.conf文件。
virtual_server:
- virutal_server_ip: "192.168.1.10"
virtual_server_port: 389
...
real_servers:
- real_ip: "192.168.1.0"
real_port: 389
description: "dc0"
...
- real_ip: "192.168.1.1"
real_port: 389
description: "dc1"
...
- real_ip: "192.168.1.2"
real_port: 389
description: "dc2"
...
- virtual_server_ip: "192.168.1.10"
virtual_server_port: 636
...
real_servers:
- real_ip: "192.168.1.0"
real_port: 636
description: "dc0"
...
- real_ip: "192.168.1.1"
real_port: 636
description: "dc1"
...
- real_ip: "192.168.1.2"
real_port: 636
description: "dc2"
...
我已经具有保持角色的jinja格式,可以根据这些变量构建/etc/keepalived.conf
。
我要做的是根据domain_controllers
词典的内容分配这些变量。我该如何使用set_facts
来分配像这样的大型嵌套字典?
我只想遍历domain_controllers
,因为我想在升级和/或迁移到新的DC时更新group_vars/all
,因为我也有其他使用此变量的剧本。 / p>
是否还可以在vars/main.yml
中而不是通过set_facts
任务来分配这些变量?
答案 0 :(得分:0)
我通过以下方法解决了这个问题:
在group_vars / all中:
domain_controllers:
- ip_address: "192.168.1.0"
hostname: "dc0"
- ip_address: "192.168.1.1"
hostname: "dc1"
- ip_address: "192.168.1.2"
hostname: "dc2"
在我的vars文件中,我用以下命令调用了列表:
virtual_server:
- virutal_server_ip: "192.168.1.10"
virtual_server_port: 389
...
real_servers:
- real_ip: "{{ domain_controllers.0.ip_address }}"
real_port: 389
description: "{{ domain_controllers.0.hostname }}"
...
- real_ip: "{{ domain_controllers.1.ip_address }}"
real_port: 389
description: "{{ domain_controllers.1.hostname }}"
...
- real_ip: "{{ domain_controllers.2.ip_address }}"
real_port: 389
description: "{{ domain_controllers.2.hostname }}"
...
- virtual_server_ip: "192.168.1.10"
virtual_server_port: 636
...
real_servers:
- real_ip: "{{ domain_controllers.0.ip_address }}"
real_port: 636
description: "{{ domain_controllers.0.hostname }}"
...
- real_ip: "{{ domain_controllers.1.ip_address }}"
real_port: 636
description: "{{ domain_controllers.1.hostname }}"
...
- real_ip: "{{ domain_controllers.2.ip_address }}"
real_port: 636
description: "{{ domain_controllers.2.hostname }}"
...
不利的是,如果domain_controllers
中至少有3个项目,则剧本会出错。我仍然想找到一种方法来遍历列表。
