Ansible-playbook 试图运行命令中的命令来获取变量。或者更好的方法

Question

似乎 uname -r 没有按照我认为应该的方式执行。我尝试了几种变体。

- name: install nvidia driver with kernel module
  command: /root/{{ nvidia_driver }} -a -s --kernel-source-path /usr/src/kernels/'{uname -r}'

错误：

TASK [portal : install nvidia driver with kernel module] 

*****************************************************************************************

Answer 1

这里的问题是 uname -r 没有返回您期望的内核版本。

您应该在命令中使用 ansible_kernel Ansible fact。

- name: install nvidia driver with kernel module
  command: "/root/{{ nvidia_driver }} -a -s --kernel-source-path /usr/src/kernels/{{ ansible_kernel }}"

Answer 2

一个问题是 '{uname -r}' 是 command substitution 的不正确语法。
这就是为什么错误说 -r 是无法识别的选项。
你可以试试 $(uname -r).
