push模式 push推送这是Ansible的默认模式在主控机上编排好playbook文件push到远程主机上来执行。pull模式 pull模式就是现在要介绍的ansible-pull命令来完成的功能与push推送模式反向pull模式是远程主机 拉去git仓库的playbook文件进行执行这需要远程主机安装ansible和git。
pull模式的优点如下 1. 斜体样式不需要主控机 2. 可以并行执行playbook任务并且速度非常快 3. 连接有节点启动更加安全
pull 模式的工作流程 图片来之网络
每台远程主机上都需要安装Ansible 和git(svn)所有的配置及playbooks 都存放在git 仓库远程主机的ansible-pull 计划任务会定期检查给定的git 的tag 或者分支ansible-pull 执行特定的playbooks 即local.yml 或者hostname.yml每次更改playbooks 只需要提交到git 即可
实验测试: 在gitee上创建一个用于测试的库pull-test
将这个库下载下来并创建playbook剧本文件上传到pull-test库 #touchfile-playbook.yaml 内容如下
# cat touchfile-playbook.yaml

git push ansible-pull可以在gitee仓库上查看文件是否被推送上去 # ansible-pull -U https://gitee.com/crazy-stone-man/pull-test.git touchfileplaybook.yaml-U 指定playbook的URL。 -i: 指定inventory文件 我这里忽略了默认是 看看效果

修改文件重新上传再次执行

学习更多功能使用 我创建的git仓库是公开的在真实环境是不能公开的而且最好是限制IP 加入定时任务 定时去拉取playbook文件执行
*/5 * * * * ansible-pull -C master -d /tmp/ansible-pull -i /etc/ansible/hosts -U https://gitee.com/crazy-stone-man/pull-test.git -o-C 指定分支 checkout功能-d Ansible Pull 将要使用的工作目录。它会将仓库克隆到这个目录或者在该目录中查找已经克隆的仓库。-i 指定 inventory 文件路径-U 指定存储 playbook 的远程 Git 仓库的 URL。-o 只有playbook 远程Git仓库更新才执行
