一、下载centos镜像
下载自己需要的版本TAG，详见：
$ sudo docker pull centos:centos7
二、下载jdk1.8，并上传到/usr/local/src目录，然后解压
$ sudo cd /usr/local/src $ sudo tar zxf jdk-8u201-linux-x64.tar.gz $ sudo ls jdk1.8.0_201 jdk-8u201-linux-x64.tar.gz
三、创建Dockerfile
先在/usr/local目录下创建jdk目录，并将/usr/local/src下的jdk-8u201-linux-x64.tar.gz复制到/usr/local/jdk目录下，然后创建Dockerfile文件
$ sudo mkdir /usr/local/jdk $ sudo cd /usr/local/jdk $ sudo cp ../src/jdk-8u201-linux-x64.tar.gz ./ $ sudo ls jdk-8u201-linux-x64.tar.gz $ sudo vi Dockerfile FROM centos:centos7 MAINTAINER tom RUN mkdir /usr/local/jdk WORKDIR /usr/local/jdk ADD jdk-8u201-linux-x64.tar.gz /usr/local/jdk ENV JAVA_HOME /usr/local/jdk/jdk1.8.0_201 ENV JRE_HOME /usr/local/jdk/jdk1.8.0_201/jre ENV PATH $JAVA_HOME/bin:$PATH
四、使用Dockerfile构建jdk1.8镜像
$ sudo docker build -t jdk1.8 . Sending build context to Docker daemon 191.8MB Step 1/8 : FROM centos:centos7 ---> 9f38484d220f Step 2/8 : MAINTAINER tom ---> Running in 9ebabac7e9e0 Removing intermediate container 9ebabac7e9e0 ---> 6e65e30640c0 Step 3/8 : RUN mkdir /usr/local/jdk ---> Running in 5805a4f50285 Removing intermediate container 5805a4f50285 ---> 8ebaedf8bd72 Step 4/8 : WORKDIR /usr/local/jdk ---> Running in c68e7f94ce6d Removing intermediate container c68e7f94ce6d ---> f4df19bf9468 Step 5/8 : ADD jdk-8u201-linux-x64.tar.gz /usr/local/jdk ---> 1fa5d55acc2e Step 6/8 : ENV JAVA_HOME /usr/local/jdk/jdk1.8.0_201 ---> Running in c9c93a299d59 Removing intermediate container c9c93a299d59 ---> 09b5bfd906dc Step 7/8 : ENV JRE_HOME /usr/local/jdk/jdk1.8.0_201/jre ---> Running in d4509f0c2af8 Removing intermediate container d4509f0c2af8 ---> 1d6b070b3985 Step 8/8 : ENV PATH $JAVA_HOME/bin:$PATH ---> Running in 190dde73be87 Removing intermediate container 190dde73be87 ---> 50016b7aac0c Successfully built 50016b7aac0c Successfully tagged jdk1.8:latest
五、在镜像仓库中查看是否构建成功
$ sudo docker images REPOSITORY TAG IMAGE ID CREATED SIZE jdk1.8 latest 50016b7aac0c 10 seconds ago 598MB
六、启动jdk容器
$ sudo docker run -di --name=jdk1.8 jdk1.8 e04f670691cd301b28fb56c25b12eae4851f583fa7abac367164a0ee68ad7241
七、进入jdk容器，查看是否安装正确（即查看安装之后的目录）
$ sudo docker exec -it jdk1.8 /bin/bash [root@7d539233feb0 jdk]# pwd /usr/local/jdk [root@7d539233feb0 jdk]# ls jdk1.8.0_201
