当前用到的环境是:
- Centos 7.5
- docker-ce 18.06.1-ce
1、先用centos7.5.1804的基础镜像把一些运行需要的环境装好
在/app目录下创建相对应的文件目录
1
2
3
4
|
[root@node2 /app/ ] # mkdir dockerfile/{web/{nginx,tomcat,jdk,apache},system/{centos,ubuntu,redhat}} -pv
[root@node2 /app ] # cd dockerfile/system/centos/
[root@node2 /app/dockerfile/system/centos ] # mkdir centos-7.5-base
[root@node2 /app/dockerfile/system/centos ] # cd centos-7.5-base
|
创建一个Dockerfile文件

[root@node2 /app/dockerfile/system/centos/centos-7 .5-base] #vim Dockerfile
#Nginx Base Image
FROM centos:7.5.1804
LABEL maintaier "mr.luo <mr.luo@dklwj.com>"
RUN yum install -y vim wget pcre pcre-devel zlib zlib-devel openssl openssl-devel iproute net-tools iotop
|
创建一个用于直接docker build脚本后续直接执行脚本即可

|
[root@node2 /app/dockerfile/system/centos/centos-7 .5-base] #vim build-command.sh
#!/bin/bash
docker build -t 172.20.7.50 /baseimages/centos-base :7.5.1804 .
|
执行脚本创建新镜像

Successfully tagged 172.20.7.50 /baseimages/centos-base :7.5.1804

2、利用制作好的基础环境镜像制作jdk的镜像
从centos-7.5-base退出来在当前目录创建一个jdk1.8的目录.
1

|
[root@node2 /app/dockerfile/system/centos/centos-7 .5-base] # cd ..
[root@node2 /app/dockerfile/system/centos ] # mkdir jdk1.8
[root@node2 /app/dockerfile/system/centos ] # cd jdk1.8/
|
创建Dockerfile

[root@node2 /app/dockerfile/system/centos/jdk1 .8] #vim Dockerfile
FROM 172.20.7.50 /baseimages/centos-base :7.5.1804
LABEL maintainer "mr.luo <mr.luo@dklwj.com>"
ADD jdk-8u162-linux-x64. tar .gz /usr/local/src/
RUN ln -s /usr/local/src/jdk1 .8.0_162/ /usr/local/jdk
ADD profile /etc/profile
ENV JAVA_HOME /usr/local/jdk
ENV JRE_HOME $JAVA_HOME /jre
ENV CLASSPATH $JAVA_HOME /lib/ :$JRE_HOME /lib/
ENV PATH $PATH:$JAVA_HOME /bin
RUN rm -rf /etc/localtime && ln -snf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime && echo "Asia/Shanghai" > /etc/timezone
|
上传jdk包到当前目录下:
复制/etc/profile文件到当前目录
1
|
[root@node2 /app/dockerfile/system/centos/jdk1 .8] #cp profile /etc/profile
|
在profile最后添加jdk的环境变量
1

|
[root@node2 /app/dockerfile/system/centos/jdk1 .8] #vim profile
export JAVA_HOME= /usr/local/jdk
export TOMCAT_HOME= /apps/tomcat
export PATH=$JAVA_HOME /bin :$JAVA_HOME /jre/bin :$TOMCAT_HOME /bin :$PATH
export CLASSPATH=.$CLASSPATH:$JAVA_HOME /lib :$JAVA_HOME /jre/lib :$JAVA_HOME /lib/tools .jar
|
创建docker build的shell脚本

|
[root@node2 /app/dockerfile/system/centos/jdk1 .8] #vim build-command.sh
#!/bin/bash
#
docker build -t 172.20.7.50 /baseimages/centos7 .5-jdk:8.162 .

3、做Tomcat的镜像
进入之前建好的/app/dockerfile/web/tomcat下,创建一个tomcat-base目录
1

|
[root@node2 ~] # cd /app/dockerfile/web/tomcat
[root@node2 /app/dockerfile/web/tomcat ] #mkdir tomcat-base
|
