使用jenkins构建docker镜像,启动docker镜像，推送镜像到harbor镜像仓库

Jenkins配置：

 

 

#操作/项目路径(Dockerfile存放的路劲)
BACKUP_PATH=/usr/local/Docker/project/backup
BASE_PATH=/usr/local/Docker/project/rm_frontend
# 源jar路径  
SOURCE_PATH=/root/.jenkins/workspace/riskManagementFrontend_Docker/target  
#docker 镜像/容器名字 这里都命名为这个,定义为jenkins任务的名称
SERVER_NAME=docker_rm_frontend
#jar名字
JAR_NAME=riskManagementFrontend-0.0.1-SNAPSHOT
#容器id
CID=$(docker ps -a | grep "$SERVER_NAME" | awk '{print $1}')
#镜像id
IID=$(docker images | grep "$SERVER_NAME" | awk '{print $3}')
 
DATE=`date +%Y%m%d%H%M`


# 备份
function backup(){
	if [ -f "$BASE_PATH/$JAR_NAME.jar" ]; then
    	echo "$JAR_NAME.jar 备份..."
        	cp $BASE_PATH/$JAR_NAME.jar $BACKUP_PATH/$JAR_NAME-$DATE.jar
        echo "备份 $JAR_NAME.jar 完成"
    else
    	echo "$BASE_PATH/$JAR_NAME.jar不存在，跳过备份"
    fi
}


# 迁移，最新构建代码 移动到项目环境
function transfer(){
    echo "最新构建代码 $SOURCE_PATH/$JAR_NAME.jar 迁移至 $BASE_PATH ...."
        cp $SOURCE_PATH/$JAR_NAME.jar $BASE_PATH 
    echo "迁移完成"
}

	transfer

    docker push 192.168.20.123/gongkai/$SERVER_NAME:$DATE

/usr/local/Docker/project/cf_apply_backend/Dockerfile文件的内容：
