## 九、IDEA整合Docker ##

### 实战springboot微服务打包镜像 ###

1.  构建springboot项目并打包为jar包 **demo-0.0.1-SNAPSHOT.jar**
2.  创建 Dockerfile

FROM java:8
    
    COPY *.jar /app.jar
    
    CMD ["server.port=8080"]
    
    EXPOSE 8080
    
    ENTRYPOINT ["java","-jar","/app.jar"]

1.  生成镜像

#1.将.jar 包和 Dockerfile 一起上传到 虚拟机
    [root@kk home]# cd idea/
    [root@kk idea]# ls
    demo-0.0.1-SNAPSHOT.jar  Dockerfile
    
    #2.构建镜像
    [root@kk idea]# docker build -t my-idea-demo .
    Sending build context to Docker daemon  17.06MB
    Step 1/5 : FROM java:8

    #3.查看新生成的镜像
    [root@kk idea]# docker images

    #4.运行容器
    [root@kk idea]# docker run -d -P --name idea-hello my-idea-demo

    #5.访问
    [root@kk idea]# curl localhost:49160
    hello,docker...
    [root@kk idea]# curl localhost:49160/test
    { "timestamp":"2021-04-16T14:28:24.866+00:00","status":404,"error":"Not Found","message":"","path":"/test"}

以上是单机版的docker我们就会使用了。
