1.下载jdk8
wget --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie" "http://download.oracle.com/otn-pub/java/jdk/8u141-b15/336fa29ff2bb4ef291e347e091f7f4a7/jdk-8u141-linux-x64.tar.gz"
下载tomcat8 暂不用
wget https://archive.apache.org/dist/tomcat/tomcat-8/v8.0.23/bin/apache-tomcat-8.0.23.tar.gz
2.创建dockerfile文件
FROM centos:latest #使用ADD指令会直接对jdk-8u141-linux-x64.tar.gz进行解压 不用单独的tar解压 ADD jdk-8u141-linux-x64.tar.gz /usr/local/ ENV JAVA_HOME /usr/local/jdk1.8.0_141 ENV CLASSPATH $JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar ENV PATH $PATH:$JAVA_HOME/bin
3.用dockerfile文件创建jdk镜像
[root@insure jdk8]# docker build -t jdk-8u141:20181222 . -f dockerfile Sending build context to Docker daemon 185.5MB Step 1/5 : FROM centos:latest ---> 1e1148e4cc2c Step 2/5 : ADD jdk-8u141-linux-x64.tar.gz /usr/local/ ---> 65475cb92b9e Step 3/5 : ENV JAVA_HOME /usr/local/jdk1.8.0_141 ---> Running in 4537fa128bf8 Removing intermediate container 4537fa128bf8 ---> a5ec3ad7eefd Step 4/5 : ENV CLASSPATH $JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar ---> Running in 170040d357ac Removing intermediate container 170040d357ac ---> 70417d2b9cad Step 5/5 : ENV PATH $PATH:$JAVA_HOME/bin ---> Running in eacfe0487c6a Removing intermediate container eacfe0487c6a ---> c717428b1276 Successfully built c717428b1276 Successfully tagged jdk-8u141:20181222 [root@insure jdk8]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE jdk-8u141 20181222 c717428b1276 18 seconds ago 578MB centos latest 1e1148e4cc2c 2 weeks ago 202MB openjdk latest 8e7eacedab93 2 weeks ago 986MB
命令说明:使用-f 指定要使用的dockerfile，如果不指定会寻找当前目录名为dockerfile的文件
-t 指定镜像的名称和tag
4.运行创建的镜像
[root@insure jdk8]# docker run -d -it jdk-8u141:20181222 /bin/bash 14c0f65b236c89c84723fe9e3f7011e405f388bf443608f054aaf24d5c290882 [root@insure jdk8]# docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 14c0f65b236c jdk-8u141:20181222 "/bin/bash" 5 seconds ago Up 4 seconds vigorous_yonath
