记录下用ansible对java项目的发包，此处项目是springboot，只需要简单的java -jar xxxx.jar即可运行

看一下对接到jenkins中的大致playbook

    - name: start
      shell: "cd {{ deploy_dir }} && nohup java -jar {{ jar_name }} --server.port=8081  >/dev/null 2>&1 &"

对应的运行命令

1
cd deploy && ansible-playbook -i hosts task.yaml -e "project_name=${project_name}" "jar_path=${jar_path}" "jar_name=${jar_name}"

对应的输出类似如下
