KodExplorer 是一款网页文件管理器。它也是一个网页代码编辑器，可让你直接在网页浏览器中开发网站。也可以在 Linux、Windows 或 Mac 平台上在线或本地运行 KodExplorer。唯一的要求是必须有 PHP 5。

容器化部署MariaDB

编写Dockerfile文件构建mysql镜像，要求基于centos完成MariaDB数据库的安装与配置，并设置服务开机自启。编写Dockerfile构建镜像explorer-mysql:v1.0，要求使用centos7.9.2009镜像作为基础镜像，完成MariaDB数据库的安装，设置root用户的密码为root，并设置MariaDB数据库开机自启。

[root@k8s-master-node1 ~]# tar -xf Explorer.tar.gz
[root@k8s-master-node1 ~]# ls
anaconda-ks.cfg  Explorer.tar.gz  KodExplorer
[root@k8s-master-node1 ~]# cd KodExplorer/
[root@k8s-master-node1 KodExplorer]# ls
CentOS_7.9.2009.tar  data  mysql  nginx  php  redis  yum
[root@k8s-master-node1 KodExplorer]#

上传centos镜像

[root@k8s-master-node1 KodExplorer]# docker load -i CentOS_7.9.2009.tar
Loaded image: centos:centos7.9.2009

[root@k8s-master-node1 KodExplorer]# vi mysql_init.sh
[root@k8s-master-node1 KodExplorer]# cat mysql_init.sh
#!/bin/bash
mysql_install_db --user=root
mysqld_safe --user=root &
sleep 8
mysqladmin -u root password 'root'
mysql -uroot -proot -e "grant all on *.* to 'root'@'%' identified by 'root'; flush privileges;"

baseurl=file:///root/yum
gpgcheck=0
enabled=1
[root@k8s-master-node1 KodExplorer]#

编写dockerfile文件

[root@k8s-master-node1 KodExplorer]# vi Dockerfile-mariadb
[root@k8s-master-node1 KodExplorer]# cat Dockerfile-mariadb
FROM centos:centos7.9.2009
MAINTAINER Chinaskills
RUN rm -rfv /etc/yum.repos.d/*

RUN yum -y install mariadb-server
COPY mysql_init.sh /opt/
RUN bash /opt/mysql_init.sh
EXPOSE 3306
CMD ["mysqld_safe","--user=root"]

构建镜像

[root@k8s-master-node1 KodExplorer]# docker build -t explorer-mysql:v1.0 -f Dockerfile-mariadb .

容器化部署Redis

编写Dockerfile文件构建redis镜像，要求基于centos完成Redis服务的安装和配置，并设置服务开机自启。编写Dockerfile构建镜像explorer-redis:v1.0，要求使用centos7.9.2009镜像作为基础镜像，完成Redis服务的安装，修改其配置文件关闭保护模式，并设置Redis服务开机自启。

[root@k8s-master-node1 KodExplorer]# vi Dockerfile-redis
[root@k8s-master-node1 KodExplorer]# cat Dockerfile-redis
FROM centos:centos7.9.2009
MAINTAINER Chinaskills
RUN rm -rf /etc/yum.repos.d/*
COPY local.repo /etc/yum.repos.d/
COPY yum /root/yum
RUN yum -y install redis
RUN sed -i 's/127.0.0.1/0.0.0.0/g' /etc/redis.conf && \sed -i 's/protected-mode yes/protected-mode no/g' /etc/redis.conf
EXPOSE 6379
CMD ["/usr/bin/redis-server","/etc/redis.conf"]
[root@k8s-master-node1 KodExplorer]#

构建镜像

[root@k8s-master-node1 KodExplorer]# docker build -t explorer-redis:v1.0 -f Dockerfile-redis .

容器化部署PHP

编写Dockerfile文件构建explorer镜像，要求基于centos完成PHP和HTTP环境的安装和配置，并设置服务开机自启。编写Dockerfile构建镜像explorer-server:v1.0，要求使用centos7.9.2009镜像作为基础镜像，完成HTTP和PHP服务的安装，然后将kodexplorer4.37.zip解压到/var/www/html目录下，修改HTTP服务的监听地址为本机，并设置HTTP服务开机自启。

编写dockerfile文件

[root@k8s-master-node1 KodExplorer]# vi Dockerfile-php
[root@k8s-master-node1 KodExplorer]# cat Dockerfile-php
