Case implementation

1. Basic environment preparation

（1） Import package

Download and unzip the package ：

[[email protected] ~]# tar -xf Pig.tar.gz
[[email protected] ~]# ll Pig
total 206752
-rw------- 1 root root 211696640 Jan 12 17:24 CentOS_7.9.2009.tar
drwxr-xr-x 2 root root        85 Jan  5 08:58 mysql
drwxr-xr-x 3 root root        37 Jan  5 08:56 nginx
drwxr-xr-x 2 root root        97 Jan  5 08:56 service
drwxr-xr-x 3 root root     12288 Jan  5 08:56 yum

Import CentOS:7.9.2009 Mirror image ：

[[email protected] ~]# docker load -i Pig/CentOS_7.9.2009.tar 
Loaded image: centos:centos7.9.2009

（2） start-up Kubernetes colony

initialization Kubernetes colony ：
[[email protected] ~]# init-cluster
View the cluster status ：
[[email protected] ~]# kubectl cluster-info
Kubernetes control plane is running at https://apiserver.cluster.local:6443
CoreDNS is running at https://apiserver.cluster.local:6443/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy

To further debug and diagnose cluster problems, use ‘kubectl cluster-info dump’.

2. Containerized deployment MariaDB

（1） To write Dockerfile

To write init.sh Script ：

[[email protected] ~]# cd Pig/
[[email protected] Pig]# vi 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;"
mysql -uroot -proot -e "source /opt/pig.sql;source /opt/pig_codegen.sql;source /opt/pig_config.sql;source /opt/pig_job.sql;"

To write yum Source ：

[[email protected] Pig]# vi local.repo
[pig]
name=pig
baseurl=file:///root/yum
gpgcheck=0
enabled=1

To write Dockerfile file ：

[[email protected] Pig]# vi Dockerfile-mariadb 
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
ENV LC_ALL en_US.UTF-8
RUN yum -y install mariadb-server
COPY mysql /opt/
COPY mysql_init.sh /opt/
RUN bash /opt/mysql_init.sh
EXPOSE 3306
CMD ["mysqld_safe","--user=root"]

（2） Build a mirror image
