通过Docker部署springboot工程

  • 打包
guodong@mars springboot-webapp-docker % mvn package spring-boot:repackage

VOLUME ["/data"] 创建一个可以从本地主机或其他容器挂载的挂载点；
ADD <src> <dest> 该命令将复制指定的<src>到容器中的<dest>
ENTRYPOINT 配置容器启动后执行的命令，每个Dockerfile中只能有一个ENTRYPOINT
EXPOSE 告诉Docker服务端容器暴露的端口号

FROM java:8
VOLUME /tmp
ADD springboot-webapp-docker-1.0.0.war springboot-webapp-docker-1.0.0.war
ENTRYPOINT ["java","-jar","/springboot-webapp-docker-1.0.0.war"]
EXPOSE 8082
  • 创建镜像

docker build -t springboot-webapp-docker src/main/docker/ 命令:
通过-t 指定镜像的标签信息，希望生成镜像标签为springboot-webapp-docker 指定Dockerfile所在路径为src/main/docker/

guodong@mars springboot-webapp-docker % cd springboot-webapp-docker
guodong@mars springboot-webapp-docker % cp target/springboot-webapp-docker-1.0.0.war src/docker/
guodong@mars springboot-webapp-docker % docker build -t springboot-webapp-docker src/main/docker/
guodong@mars springboot-webapp-docker % docker images
REPOSITORY                       TAG                 IMAGE ID            CREATED             SIZE
springboot-webapp-docker         latest              c5150ce0e9f6        36 minutes ago      660MB
  • 运行容器
guodong@mars springboot-webapp-docker % docker run -p 8082:8082 --name springboot-webapp-docker -d springboot-webapp-docker
guodong@mars springboot-webapp-docker % docker ps
CONTAINER ID        IMAGE                        COMMAND                  CREATED             STATUS              PORTS                    NAMES
