Issue with nested variables in YAML (ansible)
问题
我在使用YAML格式的变量时遇到了问题。
我正在尝试在同一个任务中使用Ansible为x86_64和s390x平台安装软件包：
vars:
x86_64_pckg:
- p1
- p2
- p3
s390x_pckg:
- p4
- p5
name: 安装备份工具
yum:
name: "{{ {{ ansible_architecture }}_pckg }}"
state: latest
我认为问题出在引号上。但也许只能通过创建两个任务并使用when:条件来处理不同的架构来解决我的问题。

I'm facing an issue when playing with variables in YAML format
I'm trying in the same task to install packages for both x86_64 and s390x platform with ansible :
vars:
x86_64_pckg:
- p1
- p2
- p3
s390x_pckg:
- p4
- p5
name: install backup tool
yum:
name: "{{ {{ ansible_architecture }}_pckg }}"
state: latest
I'm struggling with the quotes I think. But maybe my issue could only be resolved by creating two tasks and using the when: condition for managing the different architectures

如果你想要处理嵌套变量，你应该使用 ansible.builtin.vars 查找。
所以，如果你将
"{{ {{ ansible_architecture }}_pckg }}"
改为
"{{ lookup('ansible.builtin.vars', ansible_architecture + '_pckg') }}"
你将能够创建一个嵌套变量。
更多信息请查阅文档：https://docs.ansible.com/ansible/latest/collections/ansible/builtin/vars_lookup.html
英文:
If you want to work with nested variables you should use ansible.builtin.vars lookup.
So, if you change
"{{ {{ ansible_architecture }}_pckg }}"
to
"{{ lookup('ansible.builtin.vars', ansible_architecture + '_pckg') }}"
you'll be able to make a nested variable.

将哈希值放入字典中。然后，使用方法很简单
vars:
pkg:
x86_64: [p1, p2, p3]
s390x: [p4, p5]
tasks:
- yum:
name: "{{ pkg[ansible_architecture] }}"
state: latest
英文:
Put the hashes into a dictionary. Then, the usage is trivial
vars:
pkg:
x86_64: [p1, p2, p3]
s390x: [p4, p5]
tasks:
- yum:
name: "{{ pkg[ansible_architecture }}"
state: latest
