在Role 中定义变量,只需要在 roles/{role_name}/vars/main.yml YAML 文件中定义即可,其中列出的 variables 将被添加到 play 中。 Role Default Variables Role Default Variables(角色默认变量)允许你为 included roles 或者 dependent roles 设置默认变量。要创建默认变量,只需在 roles 目录下添加 defaults/main.ym...
command line values (for example, -u my_user, these are not variables) 这里使用变量ansible_user,它一般对应参数 -u 或 inventory文件的 ansible_user变量 这里说的最低的优先级是: 如果inventory配置了ansible_user 大于 -u 权重 ansible的非 -e 方式传递参数权重最低 priority01.yml ---hosts:ubuntutask...

为了理解variables,你会需要深入理解 Conditionals 和Loop 。像 group_by 和 when 条件这样有用的东西,可以和variables一起使用,来帮助管理系统间的不同。 强烈建议你学习 ansible-examples github代码库,里面有大量使用变量的例子。 对于最好的实践建议,参考最佳实践章节: Variables and Vaults ...
You can define variables when you run your playbook by passing variables at the command line using the--extra-vars(or-e) argument. You can also request user input with avars_prompt(seeInteractive input: prompts). When you pass variables at the command line, use a single quoted string, tha...

Ansible supports several sources for configuring its behavior, including an ini file named ansible.cfg, environment variables, command-line options, playbook keywords, and variables. See Controlling how Ansible behaves: precedence rules for details on the relative precedence of each source.The...
关于什么ansible,我这里就不做科普了,总之一句话,要做分布式系统的运维,实现批量系统配置、批量程序部署、批量运行命令等功能,ansible就是一大杀器,能令你事半功倍。 但作为一个cli工具,其使用场景还是受cli的限制,无法实现运行过程中更深入的交互和逻辑控制。ansible本身是用python做的,所以实际上是和python的脚本控...
