容器云实战
作者：行癫（盗版必究）
一：环境介绍
应用商城Mall重新实现全容器化部署，原应用商城系统各模块功能及系统架构如下：
| 模块 | 使用技术 | 备注 |
|---|---|---|
| mall.sql | MySQL | 网站的数据库 |
| dist目录 | Nginx | 网站的前端项目 |
| mall-shopping | web项目 | 8081端口，商品/购物车/首页渲染等交互 |
| mall-user | 8082端口，提供用户相关的交互，如登录、注册、个人中心等 | |
| user-provider | 后端服务 | 提供用户相关服务 |
| shopping-provider | 提供购物车、推荐商品、商品等服务 |
二：项目部署
1.数据库镜像
制作数据库MySQL镜像，镜像名为mall-mysql:v1.1，设置数据库支持UTF-8编码，设定root用户的密码为123456，并设置服务开机自启
[root@xingdian ~]# docker pull mariadb:latest
[root@xingdian ~]# docekr tag mariadb:latest chinaskill:mariadb:v1.1
2.redis镜像
制作Redis镜像，镜像名为chinaskill-redis:v1.1，使用centos:centos7.9.2009基础镜像，安装Redis服务，设置Redis免密，并关闭保护模式，开放端口6379，并设置服务开机自启
[root@xingdian redis]# ls
Dockerfile redis-4.0.4 redis-4.0.4.tar.gz redis.conf
redis下载地址：https://download.redis.io/releases/redis-4.0.4.tar.gz
[root@xingdian redis]# wget https://download.redis.io/releases/redis-4.0.4.tar.gz
准备redis配置文件
[root@xingdian redis]# git clone https://gitee.com/xingdiancloud/redids-config.git
编写Dockerfile文件
[root@xingdian redis]# cat Dockerfile
FROM centos:centos7.5.1804
MAINTAINER Chinaskill
RUN yum -y install gcc make
ADD redis-4.0.4.tar.gz /opt/
RUN mv /opt/redis-4.0.4 /opt/redis
WORKDIR /opt/redis
RUN make && make install
RUN rm -rf /opt/redis/redis.conf
COPY redis.conf /opt/redis
EXPOSE 6379
CMD ["redis-server","/opt/redis/redis.conf"]
构建镜像
[root@xingdian redis]# docker build -t chinaskill-redis:v1.1 .
3.zookeeper镜像
编写Dockerfile制作ZooKeeper镜像，镜像名为chinaskill-zookeeper:v1.1，使用centos:7.9.2009基础镜像，安装ZooKeeper服务，开放端口2181；并设置服务开机自启
[root@xingdian zookeeper]# ls
apache-zookeeper-3.6.3-bin Dockerfile jdk-8u211-linux-x64.tar.gz
apache-zookeeper-3.6.3-bin.tar.gz jdk1.8.0_211
zookeeper下载地址：https://dlcdn.apache.org/zookeeper/zookeeper-3.6.3/apache-zookeeper-3.6.3-bin.tar.gz
[root@xingdian zookeeper]# wget https://dlcdn.apache.org/zookeeper/zookeeper-3.6.3/apache-zookeeper-3.6.3-bin.tar.gz --no-check-certificate
JDK下载地址：https://share.weiyun.com/LHhEjTmG
编写Dockerfile文件
[root@xingdian zookeeper]# cat Dockerfile
FROM centos:centos7.5.1804
MAINTAINER Chinaskill
ADD jdk-8u211-linux-x64.tar.gz /usr/local
ADD apache-zookeeper-3.6.3-bin.tar.gz /usr/local/
RUN yum -y install vim net-tools telnet tree git wget
WORKDIR /usr/local
ENV JAVA_HOME=/usr/local/jdk1.8.0_211
ENV PATH=$JAVA_HOME/bin:$PATH
ENV ZOOKEEPER_HOME=/usr/local/apache-zookeeper-3.6.3-bin
RUN cp $ZOOKEEPER_HOME/conf/zoo_sample.cfg $ZOOKEEPER_HOME/conf/zoo.cfg
EXPOSE 2181
CMD $ZOOKEEPER_HOME/bin/zkServer.sh start-foreground
构建镜像
[root@xingdian zookeeper]# docker build -t chinaskill-zookeeper:v1.1 .
4.kafka镜像
编写Dockerfile制作Kafka镜像，镜像名为chinaskill-kafka:v1.1，使用centos:centos7.9.2009基础镜像，安装Kafka服务，开放端口9092，并设置服务开机自启
[root@nfs-harbor kafka]# ls
Dockerfile jdk-8u211-linux-x64.tar.gz kafka_2.11-2.1.0.tgz start.sh
kafka下载地址：https://archive.apache.org/dist/kafka/2.1.0/kafka_2.11-2.1.0.tgz
[root@xingdian kafka]# wget https://archive.apache.org/dist/kafka/2.1.0/kafka_2.11-2.1.0.tgz
JDK下载地址：https://share.weiyun.com/LHhEjTmG
编写Dockerfile文件
[root@nfs-harbor kafka]# cat start.sh
$KAFKA_HOME/bin/zookeeper-server-start.sh $KAFKA_HOME/config/zookeeper.properties &
sleep 20
$KAFKA_HOME/bin/kafka-server-start.sh $KAFKA_HOME/config/server.properties
[root@nfs-harbor kafka]# cat Dockerfile
FROM centos:7
ADD jdk-8u211-linux-x64.tar.gz /usr/local
ADD kafka_2.11-2.0.0.tgz /usr/local
ENV JAVA_HOME=/usr/local/jdk1.8.0_211
ENV PATH=$PATH:$JAVA_HOME/bin
ENV KAFKA_HOME=/usr/local/kafka_2.11-2.0.0
EXPOSE 9092
COPY start.sh /
CMD ["sh","/start.sh"]
构建镜像
[root@xingdian kafka]# docker build -t chinaskill-kafka:v1.1 .
4.nginx镜像
