1、with_items with_items是playbooks中最基本也是最常用的循环语句: tasks: - name:Secure config files file: path=/etc/` item ` mode=0600 owner=root group=root with_items: - my.cnf - shadow - fstab 1. 2. 3. 4. 5. 6. 7. 上面例子表示,创建三个文件分别为my.cnf、shadow、fstab 也可以...

在Ansible Playbook中定义一个循环,可以使用with_items关键字来指定循环的对象。例如: 代码语言:txt 复制 - name: Loop through YAML hosts: localhost tasks: - name: Read YAML file include_vars: file: my_vars.yaml name: my_vars - name: Loop through YAML keys ...
with_items: - pcre - pcre-devel - nginxPS:{{ item }} 定义变量 with_items 是 python list 数据结构,task会循环读取list里面的值。key的名称是item。 - pcre - pcre-devel - nginx 如果其它软件包,可将软件包名称依次写在下面。 批量安装
-name:test when conditionhosts:localhostgather_facts:novars:seq:-1-2-3-4tasks:-name:test loop and whendebug:msg:"{{ item }}"with_items:"{{ seq }}"when:item >=3 inventory 编写好playbook之后,执行命令需要指明inventory(如果不指明,就使用默认的hosts文件。) ...
with_items 数据结构对应的是python或是yaml中的列表,每个列表项也可以是字典,每次循环到的当前列表项 使用item来引用. 1.3 示例1: # standard loop name: stanard loop remote_user: root hosts: tomcat tasks: name: loop list debug: msg={{ item }} ...
