【云原生 · Kubernetes】Kubernetes 编排部署GPMall（一）

1.规划节点

2.基础准备

Kubernetes 集群已部署完成，将提供的压缩包 GPMall.tar.gz 上传到master 节点/root 目录下并解压。

3.Redis 容器化部署

（1）编写 Dockerfile
编写 yum 文件

[root@master ~]# cd gpmall/
[root@master gpmall]# cat local.repo

[gpmall]
name=gpmall
baseurl=file:///opt/gpmall
2
gpgcheck=0
enabled=1

编写 Dockerfile 文件：

[root@master gpmall]# cat Dockerfile-redis
FROM centos:centos7.5.1804
MAINTAINER Guo

# 配置 yum 源
ADD gpmall.tar /opt
RUN rm -rfv /etc/yum.repos.d/* ADD local.repo /etc/yum.repos.d/

#安装 Redis
RUN yum -y install redis

# 开放端口
EXPOSE 6379

#安装清理缓存文件
RUN yum clean all

#修改绑定 IP 地址
RUN sed -i -e 's@bind 127.0.0.1@bind 0.0.0.0@g' /etc/redis.conf

#关闭保护模式
RUN sed -i -e 's@protected-mode yes@protected-mode no@g' /etc/redis.conf

#启动
ENTRYPOINT [ "/usr/bin/redis-server","/etc/redis.conf"]
CMD []

（2）构建镜像
构建镜像 gpmall-redis:v1.0：

[root@master gpmall]# docker build -t gpmall-redis:v1.0 -f Dockerfile-redis . Sending build context to Docker daemon 507.6MB
Step 1/12 : FROM centos:centos7.5.1804

gpmall-redis    v1.0    0e71dea163a7   2 minutes ago    465MB

4.Mariadb 容器化部署

（1）编写 Dockerfile
编写数据库初始化脚本 run.sh：

[root@master gpmall]# cat mysql_init.sh
#!/bin/bash
mysql_install_db --user=mysql
(mysqld_safe &) | grep a
sleep 3s
mysqladmin -u root password '123456' sleep 3s
mysql -uroot -p123456 -e "GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIEDBY '123456'"
sleep 3s
mysql -uroot -p123456 -e "create database gpmall;use gpmall;source /opt/gpmall.sql;"
sleep 3s

编写 Dockerfile 文件：

[root@master gpmall]# cat Dockerfile-mariadb
FROM centos:centos7.5.1804
MAINTAINER Chinaskill

# 配置 yum 源
ADD gpmall.tar /opt
RUN rm -rfv /etc/yum.repos.d/* ADD local.repo /etc/yum.repos.d/

# 安装 MariaDB
RUN yum install -y MariaDB-server expect net-tools
RUN yum clean all
COPY gpmall.sql /opt/
ADD mysql_init.sh /opt/
RUN chmod +x /opt/mysql_init.sh
RUN /opt/mysql_init.sh
ENV LC_ALL en_US.UTF-8
EXPOSE 3306
CMD ["mysqld_safe"]

（2）构建镜像
构建镜像：

[root@master gpmall]# docker build -t gpmall-mariadb:v1.0 -f Dockerfile-mariadb . Sending build context to Docker daemon 507.6MB
Step 1/14 : FROM centos:centos7.5.1804
