一 調用ansible playbook api執行playbook
1 准備好hosts文件
root@ansible:~/ansible/playbooks# cat hosts [all:vars] ansible_ssh_pass=root1234 [webserver01] testserver01 ansible_ssh_host=172.20.6.121 [webserver02] testserver04 ansible_ssh_host=172.20.6.125 testserver03 ansible_ssh_host=172.20.6.124
2 准備好playbook劇本
這里准備2個把，當然可以准備多個
root@ansible:~/ansible/playbooks# cat mysql.yml
---
- name: install and config mariadb for remote host
hosts: webserver01
tasks:
- name: install mariadb for remote host
yum:
args:
name: mariadb,mariadb-server
state: present
- name: start mariadb for remote host
service:
args:
name: mariadb
state: started
- name: create database for remote mariadb
mysql_db: name=ansible_test state=present
root@ansible:~/ansible/playbooks# cat test_result.yml
---
- name: test when
hosts: webserver02
tasks:
- command: /bin/true
register: result
ignore_errors: True
- command: ls
when: result| failed
- command: df -h
when: result| success
- command: pwd
when: result| skipped
3 開始調用api吧
root@ansible:~/ansible# cat test-task.py
#!/usr/bin/env python
# coding:utf-8
import json
from collections import namedtuple
from ansible.parsing.dataloader import DataLoader
from ansible.vars import VariableManager

import os,sys
# 在指定文件時，不能使用列表指定多個。
host_path = '/root/ansible/playbooks/hosts'
if not os.path.exists(host_path):
print '[INFO] The [%s] inventory does not exist' % host_path
sys.exit()
# 管理變量的類，包括主機，組，擴展等變量，之前版本是在 inventory中的
variable_manager = VariableManager()
# 用來加載解析yaml文件或JSON內容,並且支持vault的解密
loader = DataLoader()
# 初始化需要的對象
Options = namedtuple('Options',
['connection',
'remote_user',
'ask_sudo_pass',
'verbosity',
'ack_pass',
'module_path',

# 定義默認的密碼連接，主機未定義密碼的時候才生效，conn_pass指連接遠端的密碼，become_pass指提升權限的密碼
passwords = dict(conn_pass = 'root1234',become_pass = 'root1234')
# create inventory and pass to var manager
# 創建inventory、並帶進去參數
inventory = Inventory(loader=loader,
variable_manager=variable_manager,
host_list='/root/ansible/playbooks/hosts')
# 把inventory傳遞給variable_manager管理
variable_manager.set_inventory(inventory)
# 多個yaml文件則以列表形式
playbook_path = ['/root/ansible/playbooks/mysql.yml',
'/root/ansible/playbooks/test_result.yml']
for playbook in playbook_path:
if not os.path.exists(playbook):
print '[INFO] The [%s] playbook does not exist' % playbook
sys.exit()
playbook = PlaybookExecutor(playbooks=playbook_path,
inventory=inventory,
variable_manager=variable_manager,
loader=loader,
options=options,
passwords=passwords)
# 執行playbook
result = playbook.run()
print '執行結果: %s' %(result)
4 開始執行吧
root@ansible:~/ansible# python test-task.py PLAY [install and config mariadb for remote host] ****************************** TASK [install mariadb for remote host] ***************************************** ok: [testserver01] TASK [start mariadb for remote host] ******************************************* ok: [testserver01] TASK [create database for remote mariadb] ************************************** ok: [testserver01] PLAY RECAP ********************************************************************* testserver01 : ok=3 changed=0 unreachable=0 failed=0 PLAY [test when] *************************************************************** TASK [command] ***************************************************************** changed: [testserver04] changed: [testserver03] TASK [command] ***************************************************************** skipping: [testserver03] skipping: [testserver04] TASK [command] ***************************************************************** changed: [testserver03] changed: [testserver04] TASK [command] ***************************************************************** skipping: [testserver04] skipping: [testserver03] PLAY RECAP ********************************************************************* testserver01 : ok=3 changed=0 unreachable=0 failed=0 testserver03 : ok=2 changed=2 unreachable=0 failed=0 testserver04 : ok=2 changed=2 unreachable=0 failed=0 執行結果: 0
