SpringBoot 打包为Docker进行

可以有两种方式:

  1、dockerfile

  2、maven docker

 

第一种方式:通过dockerfile打包Docker镜像

1、将dockerfile和 springboot打包的jar文件放在一起

[root@docker springboot-docker]# ls
dockerfile  hot-0.0.1.jar

2、dockerfile文件内容

FROM docker.io/ascdc/jdk8  # jdk8 基础镜像
ENV HOME_PATH /spring  # 定义目录变量
RUN ["mkdir", "-p", "/spring"]  # 在基础镜像中创建目录
ADD hot-0.0.1.jar $HOME_PATH/app.jar  # 将本地的jar目录复制到docker基础镜像中
WORKDIR $HOME_PATH  # 设置镜像工作目录
ENTRYPOINT ["java", "-jar", "app.jar"]  # 镜像启动命令

3、执行镜像生成命令

[root@docker springboot-docker]# docker build -t springboot-hot:v1 .
Sending build context to Docker daemon 18.23 MB
Step 1/6 : FROM docker.io/ascdc/jdk8

Step 3/6 : RUN mkdir -p /spring

Step 4/6 : ADD hot-0.0.1.jar $HOME_PATH/app.jar

Step 5/6 : WORKDIR $HOME_PATH
---> 421f5b686e0f

Step 6/6 : ENTRYPOINT java -jar app.jar
---> Running in 2df6bc912185
---> f89df931edfe
Removing intermediate container 2df6bc912185

4、查看本地镜像

[root@docker springboot-docker]# docker images
REPOSITORY             TAG                 IMAGE ID            CREATED             SIZE
springboot-hot         v1                  f89df931edfe        8 minutes ago       662 MB
docker.io/ascdc/jdk8   latest              9f04bbc44406        10 months ago       644 MB

5、运行springboot镜像

[root@docker springboot-docker]# docker run -d -p 8080:8080 springboot-hot:v1
78fb24c74e21f57fa3d1f543dd9c60537db65c03fb1e617819831d1c13c1b96e
[root@docker springboot-docker]# docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                    NAMES
78fb24c74e21        springboot-hot:v1   "java -jar app.jar"      2 seconds ago       Up 1 second         0.0.0.0:8080->8080/tcp   flamboyant_blackwell

6、浏览器中测试

 

PS:将war包打包到tomcat中
