今天实现ansible的roles来安装jenkins

roles目录如下

root@centos-mysql01:/data/sh/ansible_role# tree  jenkinsjenkins├── files│   ├── jenkins   #jenkins的defaults的配置文件│   ├── jenkins.io.key  # jenkins的key密钥文件│   └── jenkins.list   #jenkins的源地址文件├── handlers│   └── main.yml├── tasks│   └── main.yml└── vars    └── main.yml

handlers main.yml

root@centos-mysql01:/data/sh/ansible_role# cat jenkins/handlers/main.yml  - name: restart jenkins   listen: jenkins status   service: name=jenkins enabled=yes state=restarted - name: reload jenkins   listen: jenkins status   service: name=jenkins state=reloaded

root@centos-mysql01:/data/sh/ansible_role# cat jenkins/tasks/main.yml    - name: wget install     apt: name=wget state=latest   - name: 获取jenkins的key 导入系统     shell: wget -q -O - https://pkg.jenkins.io/debian/jenkins.io.key | sudo apt-key add -   - name: 导入list文件     shell: sudo sh -c 'echo deb http://pkg.jenkins.io/debian-stable binary/ > /etc/apt/sources.list.d/jenkins.list'   - name: 安装jenkins     apt: name=jenkins state=present   - name: jenkins conf change     copy: src=jenkins dest={
   {jenkins_conf}}     notify:       - restart jenkins   - name:  获取initalAdminPassword     shell: filepass=`cat /var/lib/jenkins/secrets/initialAdminPassword` && echo $filepass     register: say_hi    #重点显示   - debug: var=say_hi.stdout     #重点显示

我想要直接显示 jenkins部署的密码文件initalAdminPassword

- name:  获取initalAdminPassword     shell: filepass=`cat /var/lib/jenkins/secrets/initialAdminPassword` && echo $filepass     register: say_hi    #重点显示   - debug: var=say_hi.stdout     #重点显示在ansible中，任何一个模块都会返回json格式的数据，即使是错误信息都是json格式的。在ansible中，json格式的数据，其内每一项都可以通过变量来引用它。当然，引用的前提是先将其注册为变量。例如，下面的playbook是将shell模块中echo命令的结果注册为变量，并使用debug模块输出。      - hosts: benji        tasks:        - shell: echo hello world          register: hanye        - debug: var=hanye root@centos-mysql01:/data/sh/ansible_role# ansible-playbook  register.yml      TASK [debug] *********************************************************************************************************************** ok: [192.168.1.124] => {     "hanye": {         "changed": true,          "cmd": "echo hello world",          "delta": "0:00:00.066617",          "end": "2018-12-25 14:17:35.571232",          "failed": false,          "rc": 0,          "start": "2018-12-25 14:17:35.504615",          "stderr": "",          "stderr_lines": [],          "stdout": "hello world",          "stdout_lines": [             "hello world"         ]     } }

如果我想只显示其中的stdout

- hosts: benji   tasks:    - shell: echo hello world      register: hanye    - debug: var=hanye.stdout

我想显示其中的stdout第一个字符h

- hosts: benji    tasks:     - shell: echo hello world       register: hanye     - debug: var=hanye.stdout[0]

这里只需要把其换成数组展示即可

如果想要获取到对应的ip地址

ansible benji  -m setup -a "filter=*eth*"
