Jenkins配置

正常操作不阐述
将jar包、Dockerfile、gateway-server.yaml 放到master以后

nowTime=$(date "+%Y%m%d%H%M%S")
cd /app/gateway
docker build -t gateway:$nowTime . #构建镜像 有个点！
docker tag gateway:$nowTime node1:5000/gateway:$nowTime #向镜像仓库打标签
docker push node1:5000/gateway:$nowTime #推送镜像
sed 's/version-laster/'$nowTime'/g' gateway-server.yaml -i #修改gateway-server.yaml中的版本号
kubectl apply -f gateway-server.yaml #构建应用
