如何在ansible中传递多个变量?
how to pass many variables in ansible?
当我不知道如何在 with_items:
中传递许多变量时,我遇到了问题
我有这些变量:
- vars:
paths:
- /tmp/tecom/python3/
- /tmp/tecom/pip/
- /tmp/tecom/psycopg2/
- /tmp/tecom/docker/
- /tmp/tecom/postgresql/
files:
- python3.tar
- pip.tar
- psycopg2.tar
- docker.tar
- postgresql.tar
我有一个任务是提取档案:
- name: unarchive "{{ item }}"
unarchive:
src: "{{ item }}"
dest: # should take the paths above. Every path should match it's own `.tar` file.
with_items: "{{ files }}"
每个路径都应该匹配它自己的 .tar
文件。
例如,
- debug:
msg: "unarchive {{ item }} to {{ _path }}"
loop: "{{ files }}"
vars:
_path: "{{ path }}/{{ item|splitext|first }}/"
path: /tmp/tecom
files:
- python3.tar
- pip.tar
- psycopg2.tar
- docker.tar
- postgresql.tar
给出(删节)
msg: unarchive python3.tar to /tmp/tecom/python3/
msg: unarchive pip.tar to /tmp/tecom/pip/
msg: unarchive psycopg2.tar to /tmp/tecom/psycopg2/
msg: unarchive docker.tar to /tmp/tecom/docker/
msg: unarchive postgresql.tar to /tmp/tecom/postgresql/
问:“如何将这些文件解压缩到文件夹?”
A:适当使用表达方式,例如
- name: "unarchive {{ item }}"
unarchive:
src: "{{ item }}"
dest: "{{ path }}/{{ item|splitext|first }}/"
loop: "{{ files }}"
(未测试)
这取决于您将变量 files 和 path 放在哪里。参见 Variable precedence: Where should I put a variable?
