Ansible playbook lookups
1、lookups file
读取文件内容
[ansible@hk-elk-redis1 lookups]$ cat lookups.yaml
---
- hosts: all
gather_facts: False
vars:
contents: "{{ lookup(‘file‘,‘/etc/sysconfig/network‘) }}"
tasks:
- name: debug lookups
debug: msg="The contens is {% for i in contents.split("\n") %} {{ i }} {% endfor %}}"
[ansible@hk-elk-redis1 lookups]$ ansible-playbook lookups.yaml -l 10.20.11.201
PLAY [all] *******************************************************************************************************************************************************************************************************************************************************************
TASK [debug lookups] *********************************************************************************************************************************************************************************************************************************************************
ok: [10.20.11.201] => {
"msg": "The contens is # Created by anaconda }"
}
PLAY RECAP *******************************************************************************************************************************************************************************************************************************************************************
10.20.11.201 : ok=1 changed=0 unreachable=0 failed=0
2、lookups password
传入内容进行加密
[ansible@hk-elk-redis1 lookups]$ cat lookup_pass.yaml
---
- hosts: all
gather_facts: False
vars:
contents: "{{ lookup(‘password‘,‘ansible_book‘) }}"
tasks:
- name: debug lookups
debug: msg="The contents is {{ contents }}"
[ansible@hk-elk-redis1 lookups]$ ansible-playbook lookup_pass.yaml -l 10.20.11.201
PLAY [all] *******************************************************************************************************************************************************************************************************************************************************************
TASK [debug lookups] *********************************************************************************************************************************************************************************************************************************************************
ok: [10.20.11.201] => {
"msg": "The contents is :ny4_i5BAyMrOhmm8-tT"
}
PLAY RECAP *******************************************************************************************************************************************************************************************************************************************************************
10.20.11.201 : ok=1 changed=0 unreachable=0 failed=0
3、lookups pipe
pipe lookups的实现原理很简单，就是在机器上面调用subprocess.Popen执行命令，然后将命令传递给变量
[ansible@hk-elk-redis1 lookups]$ cat lookup_pipe.yaml
---
- hosts: all
gather_facts: False
vars:
contents: "{{ lookup(‘pipe‘,‘date +%Y-%m-%d‘) }}"
tasks:
- name: debug lookups
debug: msg="The contents is {% for i in contents.split("\n") %} {{ i }} {% endfor %}"
[ansible@hk-elk-redis1 lookups]$ ansible-playbook lookup_pipe.yaml -l 10.20.11.201
PLAY [all] *******************************************************************************************************************************************************************************************************************************************************************
TASK [debug lookups] *********************************************************************************************************************************************************************************************************************************************************
ok: [10.20.11.201] => {
"msg": "The contents is 2018-12-20 "
}
PLAY RECAP *******************************************************************************************************************************************************************************************************************************************************************
10.20.11.201 : ok=1 changed=0 unreachable=0 failed=0
4、lookups template
template跟file的方式有点类似，都是读取文件，但是template在读取文件之前需要吧jinja模板渲染完后再读取，下面我们指定一个jinja模板文件
[ansible@hk-elk-redis1 lookups]$ cat lookup.j2
worker_processes {{ ansible_processor_cores }};
IPaddress {{ ansible_ens192.ipv4.address }}
[ansible@hk-elk-redis1 lookups]$ cat lookup_template.yaml
---
- hosts: all
gather_facts: True
vars:
contents: "{{ lookup(‘template‘,‘./lookup.j2‘) }}"
tasks:
- name: debug lookups
debug: msg="The contents is {% for i in contents.split("\n") %} {{ i }} {% endfor %}"
[ansible@hk-elk-redis1 lookups]$ ansible-playbook lookup_template.yaml
PLAY [all] *******************************************************************************************************************************************************************************************************************************************************************
TASK [Gathering Facts] *******************************************************************************************************************************************************************************************************************************************************
ok: [10.20.11.202]
ok: [10.20.11.201]
TASK [debug lookups] *********************************************************************************************************************************************************************************************************************************************************
ok: [10.20.11.201] => {
"msg": "The contents is worker_processes 1; IPaddress 10.20.11.201 "
}
ok: [10.20.11.202] => {
"msg": "The contents is worker_processes 1; IPaddress 10.20.11.202 "
}
PLAY RECAP *******************************************************************************************************************************************************************************************************************************************************************
10.20.11.201 : ok=2 changed=0 unreachable=0 failed=0
10.20.11.202 : ok=2 changed=0 unreachable=0 failed=0
