ansible loop用法 在Ansible中，循环（loop）是一种强大的机制，它允许你对一组数据执行一系列任务。Ansible支持多种循环方式，以下是一些常见的用法：1. with_items：使用`with_items`关键字可以对列表进行循环。例如：```yaml - name: Loop through a list debug:msg: "Item: {{ item }}"with_items:- ...
ok: [192.168.100.147] TASK [Set variable `timesync_services` with filtered uniq service names] *** ok: [192.168.100.147] TASK [Check that variable 'timesync_services' is defined] *** ok: [192.168.100.147] => { "changed": false, "msg": "All assertions passed" } TASK [timesync : ...
命令行参数: 可以通过 -e "variable=value" 传递变量。 四. 高级特性 4.1 Roles Roles 是一种组织 Playbook 的方式,可以将相关的任务、文件、模板等打包在一起,便于重用和维护。 目录结构: roles/├── nginx│ ├── tasks│ │└── main.yml│ ├─...
在inventory文件中可以直接定义主机变量或主机组变量。 例如: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15# 在主机上直接定义变量[dev]192.168.200.42aaa=333bbb=444ansible_port=22192.168.200.43 192.168.200.44# 在主机组上定义变量[dev:vars]xxx=555yyy=666ansible_port=22# 也可以在特殊的主机组ungrouped...
此时我们可以使用ansible的循环语句loop(ansible 2.5以后),在2.5版本之前可以使用with_,loop类似于旧版本的with_list语句。 when语句 ansible的when语句用于判断是否执行这个task,例如 tasks: - name:"shut down Debian flavored systems"command: /sbin/shutdown -t now...

Registered variables are host-level variables. When you register a variable in a task with a loop, the registered variable contains a value for each item in the loop. The data structure placed in the variable during the loop will contain aresultsattribute, that is a list of all responses fr...
vars_prompt:variable_name:"Promptstring" Specifying variables at the top level of a task include statement is no longer supported. For example: -include_tasks:foo.ymla:1 Should now be: -include_tasks:foo.ymlvars:a:1 Setting any_errors_fatal on a task is no longer supported. This should...
