我需要创建 jinja 模板来生成 ansible 剧本,因为我需要从 csv 文件读取数据
csv 文件类似于下面(文件名 ansi.csv)
aaa,bbb,ccc,ddd
aa01,ansi,directory,yes
aa02,jinj,directory,yes
aa01,play,direvtory,yes
aa02,tem,directory,yes
我生成模板的剧本是
---
- hosts: localhost
vars:
csvfile: "{{ lookup('file', 'csv_files/ansi.csv')}}"
tasks:
- name: generate template
template:
src: template.j2
dest: playbook.yml
我创建了如下所示的模板
---
{% for item in csvfile.split("\n") %}
{% if loop.index != 1 %}
{% set list = item.split(",") %}
- name: 'make directory'
hosts: {{ list[0]|trim()}}
become: {{ list[3]}}
tasks:
- name: {{ list[1] }}
file:
path: {{list[1]}}
state: {{ list[2] }}
{% endif %}
{% endfor %}
我得到的输出剧本更简单
---
- name: 'make directory'
hosts: aa01
become: yes
tasks:
- name: ansi
file:
path: ansi
state: directory
- name: make directory
hosts: aa02
become: yes
tasks:
- name: jinj
file:
path: jinj
state: directory
- name: make directory
hosts: aa01
become: yes
tasks:
- name: play
file:
path: play
state: directory
- name: make directory
hosts: aa01
become: yes
tasks:
- name: tem
file:
path: tem
state: directory
但需要像下面这样的剧本
---
- name: 'make directory'
hosts: aa01
become: yes
tasks:
- name: ansi
file:
path: ansi
state: directory
- name: play
file:
path: play
state: directory
- name: make directory
hosts: aa02
become: yes
tasks:
- name: jinj
file:
path: jinj
state: directory
- name: tem
file:
path: tem
state: directory
在上面的剧本中,我的期望是按第一列分组,只有我必须重复任务部分(如果主机相同),有人可以帮助我实现这一目标吗?提前致谢
答案1
使用模块读取csv文件读取csv并使用过滤器通过...分组。例如下面的剧本和模板
shell> cat playbook.yml
- hosts: localhost
tasks:
- read_csv:
path: ansi.csv
register: data
- template:
src: template.j2
dest: playbook.yml
shell> cat template.j2
---
{% for host in data.list|groupby('aaa') %}
- name: 'make directory'
hosts: {{ host.0 }}
become: yes
tasks:
{% for task in host.1 %}
- name: {{ task.bbb }}
file:
path: {{ task.bbb }}
state: {{ task.ccc }}
{% endfor %}
{% endfor %}
给
shell> cat playbook.yml
---
- name: 'make directory'
hosts: aa01
become: yes
tasks:
- name: ansi
file:
path: ansi
state: directory
- name: play
file:
path: play
state: direvtory
- name: 'make directory'
hosts: aa02
become: yes
tasks:
- name: jinj
file:
path: jinj
state: directory
- name: tem
file:
path: ten
state: directory
