RUN yum install -y memcached
EXPOSE 11211
ENTRYPOINT /usr/bin/memcached -u root
[root@k8s-master-node1 DjangoBlog]# docker build -t blog-memcached:v1.0 -f Dockerfile-memcached .

容器化部署MariaDB

[root@k8s-master-node1 DjangoBlog]# 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 "create database djangoblog;use djangoblog;source /opt/sqlfile.sql;"
