微服务 在k8s中部署订单order服务

1）构建镜像

[root@master order-service]# cd order-service-biz/[root@master order-service-biz]# lsDockerfile pom.xml src target[root@master order-service-biz]# cat Dockerfile FROM java:8-jdk-alpineRUN apk add -U tzdata && \ ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtimeCOPY ./target/order-service-biz.jar ./EXPOSE 8020CMD java -jar /order-service-biz.jar[root@master order-service-biz]# docker build -t reg.harbor.com/microservice/order:v1 .Sending build context to Docker daemon 45.94MBStep 1/5 : FROM java:8-jdk-alpine ---> 3fd9dd82815cStep 2/5 : RUN apk add -U tzdata && ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime ---> Using cache ---> a9034491fdd5Step 3/5 : COPY ./target/order-service-biz.jar ./ ---> 25c3a137078aStep 4/5 : EXPOSE 8020 ---> Running in 57f22b0a96b3Removing intermediate container 57f22b0a96b3 ---> e9a11bc917b2Step 5/5 : CMD java -jar /order-service-biz.jar ---> Running in e18775330a8aRemoving intermediate container e18775330a8a ---> b9d75b047b0aSuccessfully built b9d75b047b0aSuccessfully tagged reg.harbor.com/microservice/order:v1[root@master order-service-biz]# docker push reg.harbor.com/microservice/order:v1

2）部署服务
