1. 创建一个多分支流水线项目

   - 显示名称（不太重要）

   - 分支源（非常重要）,添加Git远程仓库的url，选择用户凭证（username/password,  ssh private key）,行为选择发现分支、发现标签

   - 填写jenkinsfile在git仓库的相对路径

   - 保存

     

3. 立即扫描多分支流水线![在这里插入图片描述](https://img-blog.csdnimg.cn/20200720153042250.png?x-oss-process=image/watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXlhbmdfdGFuZw==,size_16,color_FFFFFF,t_70)
4. 选择项目的版本号tag(标签)，本文以1.1为例开始部署

            }
        }
        stage('停止旧容器') {
            steps {

                sh "docker run -it -d -p 8081:80 --name jenkinsdocker tangweiyang/jenkinsdocker:${releaseTag}"
            }
        }
    }
