在 Jenkins 中执行 Ansible playbook 以配置 EC2答案

【问题描述】：

我正在尝试运行一个 Ansible 剧本，该剧本使用 Jenkins 在 AWS 中预置 EC2 实例。我的 Jenkins 应用程序安装在具有预置实例所需角色的 EC2 上，我的 JENKINS_USER 是 ec2-user。以 ec2-user 身份登录时，我可以手动执行剧本。但是，当我尝试执行相同的 Ansible 命令时，Jenkins 会无限期地停止。

谁能确定我为什么无法使用 Jenkins 执行剧本？

【解决方案1】：

问题是 Jenkins 主节点（正在执行 Ansible 剧本的地方）缺少一些环境变量（在 Manage Jenkins>Manage Node> Configure Master 下配置）。请参阅下面我添加到 Jenkins 主节点的变量列表。

Name: http_proxy
Value: http://proxy.com:123

Name: PATH
Value: /usr/local/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/home/ec2-user/.local/bin:/home/ec2-user/bin

Name: SUDO_COMMAND
Value: /bin/su ec2-user

Name: SUDO_USER
Value: svc_ansible_lab

添加上述变量后，我可以毫无问题地执行 Ansible Playbook。
