基于Kubernetes 编排部署GPmall
目标
用k8s编码容器，部署一个商城
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
1.Redis 容器化部署
编写 yum 文件
[root@master ~]# cd gpmall/
[root@master gpmall]# cat local.repo
[gpmall]
name=gpmall
baseurl=file:///opt/gpmall
gpgcheck=0
enabled=1
编写 Dockerfile 文件
[root@master gpmall]# cat Dockerfile-redis
FROM centos:centos7.5.1804
MAINTAINER Pyy
ADD gpmall.tar /opt
RUN rm -rfv /etc/yum.repos.d/* ADD local.repo /etc/yum.repos.d/
RUN yum -y install redis
EXPOSE 6379
RUN yum clean all
RUN sed -i -e 's@bind 127.0.0.1@bind 0.0.0.0@g' /etc/redis.conf
RUN sed -i -e 's@protected-mode yes@protected-mode no@g' /etc/redis.conf
ENTRYPOINT [ "/usr/bin/redis-server","/etc/redis.conf"]
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 .
查看镜像列表
[root@master gpmall]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
gpmall-redis v1.0 7e662e15d3e4 1 minutes ago 464MB
2.Mariadb 容器化部署
编写 Dockerfile
# cat Dockerfile-mariadb
FROM centos:centos7.5.1804
MAINTAINER pyy
ADD gpmall.tar /opt
RUN rm -rfv /etc/yum.repos.d/* ADD local.repo /etc/yum.repos.d/
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]
3.ZooKeeper 容器化部署
编写 Dockerfile
root@master gpmall]# cat Dockerfile-zookeeper
FROM centos:centos7.5.1804
MAINTAINER Chinaskill
ADD gpmall.tar /opt
RUN rm -rfv /etc/yum.repos.d/* ADD local.repo /etc/yum.repos.d/
RUN yum install -y java-1.8.0-openjdk java-1.8.0-openjdk-devel
ENV work_path /usr/local
WORKDIR $work_path
ADD zookeeper-3.4.14.tar.gz /usr/local
ENV ZOOKEEPER_HOME /usr/local/zookeeper-3.4.14
ENV PATH $PATH:$JAVA_HOME/bin:$JRE_HOME/bin:$ZOOKEEPER_HOME/bin
RUN cp $ZOOKEEPER_HOME/conf/zoo_sample.cfg $ZOOKEEPER_HOME/conf/zoo.cfg
EXPOSE 2181
4.编排部署 GPMall
编写gpmall.yaml
root@master gpmall]# cat gpmall.yaml
