1.Docker安装部署
（1）.关闭防火墙
（2）.更新源
（3）设置Docker仓库
（4）启动docker
（5）查看版本：
2.Docker pull 容器并运行服务；
拉取nginx镜像，运行该nginx实例

安装 vim apt-get install vim
修改 index.html 为自己的学号和姓名(https://registry.hub.docker.com/_/nginx)
cd /usr/share/nginx/html
3.Dockerfile和Docker build定制容器；dockerfile内容显示，docker build过程截图
拉取镜像、编写 dockerfile
docker pull ubuntu:16.04
mkdir baseos
cd baseos
touch Dockerfile
vi Dockerfile
Base os image FROM ubuntu:16.04
MAINTAINER your_name <your_email_address>
LABEL Description="This image is the base os images." Version="1.0"
reconfig timezone
RUN echo "Asia/Shanghai" > /etc/timezone
docker build -t chenzhiyong/baseos:1.0 .
docker images
构建 jre 基础镜像
下载 jdk，解压，将文件中的 jre 打包
sudo mv jre jre1.8.0_321
sudo tar -zcvf jre-8u321-linux-x64.tar.gz jre1.8.0_321
sudo mkdir jre-8u321 sudo cp jre-8u321-linux-x64.tar.gz jre-8u321
cd jre-8u321/
sudo vi Dockerfile
Base jre image
FROM xjli/baseos:1.0
MAINTAINER your_name
LABEL Description="This image is used to serve Oracle jre 7u80" Version="1.0"
Install and config Oracle jre
ADD jre-8u321-linux-x64.tar.gz /usr/lib/jvm/
RUN update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/jre1.8.0_321/bin/java" 1 \
&& update-alternatives --set java /usr/lib/jvm/jre1.8.0_321/bin/java
ENV JAVA_HOME /usr/lib/jvm/jre1.8.0_321
构建 jre 镜像
docker build -t xjli/jre:8u321 .
检查版本 --rm 选项可以在容器运行完毕立即删除容器。
docker run --rm xjli/jre:8u321 java -version
构建 tomcat 基础镜像
mkdir tomcat7-jre7
cp apache-tomcat-7.0.77.tar.gz tomcat7-jre7/
cd tomcat7-jre7/
vi Dockerfile
Base image
FROM xjli/jre:8u321
MAINTAINER your_name <your_email_address>
LABEL Description="This image is used to run tomcat7 with jre7." Version="1.0"
#把 tomcat 添加到容器中
ADD apache-tomcat-7.0.77.tar.gz /usr/local
ENV CLASSPATH JAVA_HOME/lib/dt.jar:JAVA_HOME/lib/tools.jar
#配置 tomcat 环境变量
ENV CATALTNA_HOME /usr/local/apache-tomcat-7.0.77
ENV PATH PATH:JAVA_HOME/bin:$CATALTNA_HOME/bin
#设置工作目录
WORKDIR $CATALTNA_HOME
#容器端口
EXPOSE 8080 ENTRYPOINT ["catalina.sh","run"]
docker build -t xjli/tomcat:7-jre7 .
docker run -d --name mytomcat1 -p 10086:8080 xjli/tomcat:7-jre7 container:2d044b41600f
