在Jenkins中執行Ansible劇本以配置EC2

Question

我正在嘗試運行Ansible劇本，使用Jenkins在AWS中配置EC2實例。 我的Jenkins應用程序安裝在具有必需角色以供應實例的EC2上，而我的JENKINS_USER是ec2-user。 以ec2-user身份登錄后，我可以手動執行劇本。 但是，當我嘗試執行相同的確切Ansible命令時，Jenkins會無限期停止。

誰能確定我為什么無法使用詹金斯執行劇本？

問題是Jenkins主節點（正在執行Ansible劇本的節點）缺少一些環境變量（在Manage Jenkins> Manage Node> Configure Master下配置）。 請參閱下面我添加到Jenkins Master節點的變量列表。

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

添加以上變量后，我便可以毫無問題地執行Ansible Playbooks。
