章
在本地环境中工作（就像在生产环境中一样）
第一行表示应该根据
openjdk:8-jre
这个基础镜像来创建容器镜像。
openjdk:8-jre
是一个
由
OpenJDK
团队维护的镜像（
https://hub.docker.com/_/openjdk/
），包含了在
Docker
容
器中运行
Java 8
应用程序所需的一切环境（例如，一个安装和配置了
OpenJDK 8 JRE
的
操作系统）。第二行表示将可执行的
JAR
文件添加到镜像中。第三行指定应用程序侦听
端口
8010
，并且该端口必须对外暴露访问，第四行指定了容器初始化的入口点或者要执
行的命令。接下来我们来构建这个容器镜像，如示例
8-18
所示。
示例8-18：构建Docker镜像
$ docker build -t danielbryantuk/djshopfront:1.0 .
Successfully built 87b8c5aa5260
Successfully tagged danielbryantuk/djshopfront:1.0
现在我们将该镜像推送到
Docker Hub
，如示例
8-19
所示。如果你还未通过命令行登录
Docker Hub
，那么现在必须立即输入
Docker Hub
的用户名和密码。
示例8-19：将镜像推送到Docker Hub
$ docker login
Login with your Docker ID to push and pull images from Docker Hub.
