在詹金斯执行Ansible playbook以提供EC2

Question

我正在尝试使用Jenkins运行AWS中的EC2实例的Ansible操作手册。 My Jenkins应用程序安装在需要角色供应实例的EC2上，而我的JENKINS_USER是ec2用户。 我能够以ec2用户身份登录时手动执行剧本。但是，当我尝试执行同样精确的Ansible命令时，詹金斯无限期地失速。

任何人都可以确定为什么我无法使用Jenkins执行剧本吗？

Answer 1

问题是Jenkins主节点（其中Ansible playbook正在执行），缺少一些环境变量（在Manage Jenkins> Manage Node> Configure Master下配置）。请参阅下面的Jenkins主节点添加的变量列表。

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 

一旦我添加了上述变量，我就能够执行Ansible Playbooks而没有任何问题。
