制作 JDK Docker 镜像

1、下载 JDK 包

将下载的 jdk-8u231-linux-x64.tar.gz 放在与Dockerfile 一个路径

2、编写 Dockerfile

vim Dockerfile 

FROM centos:7.6.1810
MAINTAINER utf7

RUN yum install -y vim
RUN yum install -y net-tools

RUN mkdir -p /jdk64
ADD jdk-8u231-linux-x64.tar.gz /jdk64/

ENV JAVA_HOME /jdk64/jdk1.8.0_231
ENV PATH $PATH:$JAVA_HOME/bin

WORKDIR /root/

这里安装了比较常用的 vim 和net-tools

3、拉取 centos image

docker pull centos:7.6.1810

4、构建image

docker build -t utf7/jdk8 .

5、查看 docker images

# docker images
REPOSITORY                                               TAG                 IMAGE ID            CREATED             SIZE
utf7/jdk8                                                 latest              204a86499ba4        6 minutes ago       860MB

6、docker image 打 tag

docker tag 204a86499ba4 utf7/jdk8:8u231

7、运行容器

docker run -it --name utf7-jdk8 -d utf7/jdk8:8u231

8、查看容器

# docker ps -a
CONTAINER ID        IMAGE                                      COMMAND                  CREATED              STATUS                      PORTS               NAMES
3c6ed3a48c6a        utf7/jdk8:jdk8u231                          "/bin/bash"              About a minute ago   Up About a minute                               utf7-jdk8

9、进入docker 容器


#进入容器
docker exec -it utf7-jdk8 /bin/bash

#验证Java
java -version
echo $PATH
[root@3c6ed3a48c6a ~]# java -version
java version "1.8.0_231"
Java(TM) SE Runtime Environment (build 1.8.0_231-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.231-b11, mixed mode)
[root@3c6ed3a48c6a ~]# echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/jdk64/jdk1.8.0_231/bin

10、退出容器

exit

11、停止容器

docker stop 3c6ed3a48c6a

12、删除容器

docker rm 3c6ed3a48c6a

13、删除 image

docker rmi 204a86499ba4

14、删除 exited 状态的容器

docker rm $(docker ps -qf status=exited)
