Ansible:多个组中的主机

本文介绍了Ansible:多个组中的主机的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我在2个组中有一个主机:pc和Servers我在每个packages.yml文件中都有2个group_vars(PC和服务器)这些文件定义了要在PC主机和服务器主机上安装的软件包的列表

I have a host in 2 groups : pc and ServersI have 2 group_vars (pc and servers) with, in each the file packages.ymlThese files define the list of packages to be installed on pc hosts and on servers hosts

我有安装默认软件包的作用

I have a role to install default package

问题是:角色任务仅考虑group_vars/pc/packages.yml，未安装来自group_vars/servers/packages.yml的软件包

The problem is : only the group_vars/pc/packages.yml is take into account by the role task, packages from group_vars/servers/packages.yml are not installed

我当然想要安装为PC和服务器定义的软件包

Of course what I want is installation of packages defined for pc and servers

我不知道这是错误还是功能...

I do not know if it is a bug or a feature ...

感谢您的帮助

这是配置:

# file: production
[pc]
armen
kerbel
kerzo

[servers]
kerbel

---
# packages on servers
packages:
  - lftp
  - mercurial

---
# packages on pc
packages:
  - keepassx
  - lm-sensors
  - hddtemp

推荐答案

如果要使用这样的方案.您应该在ansible.cfg中设置hash_behaviour选项:

If you want to use such scheme. You should set the hash_behaviour option in ansible.cfg:

[defaults]
hash_behaviour = merge

此外，您必须使用字典而不是列表.为了防止重复，我建议使用名称作为键，例如:

In addition, you have to use dictionaries instead of lists. To prevent duplicates I recommend to use names as keys, for example:

group_vars/servers/packages.yml:

packages:
 package_name1:
 package_name2:

group_vars/pc/packages.yml:

packages:
 package_name3:
 package_name4:

在剧本任务中(| default({})-对于缺少"package"变量的情况):

And in a playbook task (| default({}) - for an absent "package" variable case):

- name: install host packages
  yum: name={{ item.key }} state=latest
  with_dict: packages | default({})
