playbook 指的是用于配置管理的脚本, 实际上playbook才是ansible的重头戏
我将尝试使用一个playbook同时控制之前创建的3个虚拟机(docker 容器)
先看一个简单脚本
[root@vagrant playbooks]# vi hostname.yml
- name: call hostname
hosts: dockers
sudo: False
tasks:
- name: install
shell: hostname > /hostname.txt直接调用
[root@vagrant playbooks]# ansible-playbook hostname.yml
PLAY [call hostname] **********************************************************
GATHERING FACTS ***************************************************************
ok: [172.17.0.4]
ok: [172.17.0.3]
ok: [172.17.0.2]
TASK: [install] ***************************************************************
changed: [172.17.0.3]
changed: [172.17.0.4]
changed: [172.17.0.2]
PLAY RECAP ********************************************************************
172.17.0.2 : ok=2 changed=1 unreachable=0 failed=0
172.17.0.3 : ok=2 changed=1 unreachable=0 failed=0
172.17.0.4 : ok=2 changed=1 unreachable=0 failed=0 检查一下结果
下面是一个安装httpd的脚本
[root@vagrant playbooks]# vi httpd.yml
- name: install httpd from yum
hosts: dockers
sudo: False
tasks:
- name: install
shell: yum install httpd
- name: start httpd
shell: /usr/sbin/httpd调用 ansible-playbook ./playbooks/httpd.yml
可以看到log中
[root@vagrant log]# tail -500f ansible.log
