docker安装jdk1.8

一、下载centos镜像

docker pull centos:centos7

二、下载jdk1.8并上传到/usr/local/src目录，进行解压

cd /usr/local/src
tar -zxvf jdk-8u221-linux-x64.tar.gz

三、创建Dockerfile
在/usr/local目录下创建jdk目录，把/usr/local/src下的jdk-8u221-linux-x64.tar.gz复制到/usr/local/jdk目录下，然后创建Dockerfile

mkdir /usr/local/jdk
cd /usr/local/jdk
cp ../src/jdk-8u221-linux-x64.tar.gz ./
vi Dockerfile

Dockerfile的内容如下

from centos:centos7
maintainer huangbaokang
run mkdir /usr/local/jdk
workdir /usr/local/jdk
add jdk-8u221-linux-x64.tar.gz /usr/local/jdk

env JAVA_HOME /usr/local/jdk/jdk1.8.0_221
env JRE_HOME /usr/local/jdk/jdk1.8.0_221/jre
env PATH $JAVA_HOME/bin:$PATH

四、使用Dockerfile构建jdk1.8镜像

[root@localhost jdk]# docker build -t jdk1.8 .

五、查看构建的镜像

[root@localhost jdk]# docker images

六、启动jdk容器

[root@localhost jdk]# docker run -di --name=jdk1.8 jdk1.8
1ab4fca37eacf244e2d89a630c7cde5bf7a3b85f5a787b7ddb7aa723d9887436

七、进入jdk容器，查看版本

[root@localhost jdk]# docker exec -it jdk1.8 /bin/bash
[root@1ab4fca37eac jdk]# java -version
java version "1.8.0_221"
Java(TM) SE Runtime Environment (build 1.8.0_221-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.221-b11, mixed mode)
