SpringBoot项目打包Docker镜像

目的：

将项目打包成docker镜像发布到服务器

将SpringBoot项目进行打包

创建Dockerfile文件

jar包本地运行没问题之后，将jar包和Dockerfile文件上传至linux服务器

我这里先启动了openjdk的镜像

将项目打成docker镜像，命令后面有个 .

docker build -t yutao666 .

[root@localhost test]# docker build -t yutao666 . Sending build context to Docker daemon 69.4MB Step 1/5 : FROM openjdk ---> 5e28ba2b4cdb Step 2/5 : COPY *.jar /app.jar ---> 4a87bb06da90 Step 3/5 : CMD ["--server.prot=8080"] ---> Running in 88a0e5e23b5d Removing intermediate container 88a0e5e23b5d ---> 6a1b6abead85 Step 4/5 : EXPOSE 8080 ---> Running in d1f514b5e6ae Removing intermediate container d1f514b5e6ae ---> 0539168cd6cc Step 5/5 : ENTRYPOINT ["java","-jar","/app.jar"] ---> Running in c3b46aba88d0 Removing intermediate container c3b46aba88d0 ---> ac6735e9a7a2 Successfully built ac6735e9a7a2 Successfully tagged yutao666:latest 

查看镜像

直接运行镜像

[root@localhost test]# docker run -d -it -p 8080:8080 yutao888 ad4d6e63611c456c33444362767ae54a1d3f2831652e2ade6dc285f142feb230 

查看镜像是否启动成功

[root@localhost test]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES ad4d6e63611c yutao666 "java -jar /app.jar …" 3 seconds ago Up 2 seconds 8080/tcp great_booth e8a75344ac62 openjdk "/bin/bash" 24 minutes ago Up 24 minutes exciting_euler 

访问成功！

PS：我这里写的是一个小demo，主要是打包流程，真正打包项目的时候将项目镜像交给运维或者测试，或者直接上传至dockerhub，别人直接拉下来，docker run 就ok了！
