一、迁移网关服务

1.5.1 环境信息

代码地址：https://gitee.com/dukuan/demo-receive.git

构建命令：mvn clean package

Java 版本：jdk 1.8

构建镜像：registry.cn-hangzhou.aliyuncs.com/abroad_images/maven:3.5.3

1.5.2 构建及容器化

1、在node01主机(10.0.0.21)下载源码

# 宿主机上创建项目目录
[root@node01 ~]# mkdir springcloud

# 下载源码
[root@k8s-node01 ~]# cd springcloud/
[root@k8s-node01 springcloud]# git clone https://gitee.com/dukuan/demo-receive.git

# 宿主机上创建缓存目录(如果上面做过此步骤可忽略)
[root@k8s-node01 springcloud]# mkdir -p /data/m2

2、在node01主机(10.0.0.21)启动临时容器，进行构建

# 启动临时容器
[root@node01 ~]# cd /root/springcloud
[root@k8s-node01 springcloud]# 
docker run -it --rm \
  -v /data/m2:/root/.m2 \
  -v "$(pwd)/demo-receive:/mnt" \
  registry.cn-hangzhou.aliyuncs.com/abroad_images/maven:3.5.3 \
  bash -c "cd /mnt && mvn clean package"

# 检查宿主机目录
[root@k8s-node01 springcloud]# ll /root/springcloud/demo-receive/target/

3、在node01主机(10.0.0.21)编写Dockfile文件

# 宿主机上同样查看，观察到已生成target目录
[root@k8s-node01 ~]# cd /root/springcloud/demo-receive/
[root@k8s-node01 demo-receive]# ll
总用量 4
-rw-r--r-- 1 root root 2170  3月 23 08:45 pom.xml
drwxr-xr-x 3 root root   18  3月 23 08:45 src
drwxr-xr-x 6 root root  165  3月 23 08:51 target

# 宿主机上查看target目录
[root@k8s-node01 demo-receive]# ll target/receive-0.0.1-SNAPSHOT.jar
-rw-r--r-- 1 root root 39016394  3月 23 08:51 target/receive-0.0.1-SNAPSHOT.jar

# 编写Dockfile文件
[root@k8s-node01 ~]# cd /root/springcloud/demo-receive/
[root@k8s-node01 demo-receive]# vim Dockerfile
# 基础镜像可以按需修改，可以更改为公司自有镜像
FROM registry.cn-hangzhou.aliyuncs.com/abroad_images/jdk:8u211-jmap
# 定义容器家目录
WORKDIR /home/tomcat
# 复制jar包
COPY target/*.jar ./
# 启动Jar包
CMD ["sh", "-c", "java -jar *.jar"]

4、在node01主机(10.0.0.21)构建镜像

[root@k8s-node01 demo-receive]# docker build -t registry.cn-hangzhou.aliyuncs.com/abroad_images/demo-receive:v0.0.1 .

# 上传镜像到阿里云仓库
[root@k8s-node01 demo-eureka]# docker push registry.cn-hangzhou.aliyuncs.com/abroad_images/demo-receive:v0.0.1
