1.定制MariaDB镜像，指定镜像的时区为中国
【注】缺省的MariaDB镜像的时区与中国时区差8小时
1)定制MariaDB镜像
远程登录master节点，执行:
mkdir /home/honsen/customize_images/mariadb -p
cd /home/honsen/customize_images/mariadb
cp /etc/localtime localtime
vi Dockerfile
FROMcentos/mariadb-101-centos7
MAINTAINERApollo.Yang
COPY./localtime /etc/localtime
#This default user is created in the openshift/base-centos7 image
USER1001
#Set the default port for applications built using this image
EXPOSE3306
#Set the default CMD for the image
CMD["/bin/run-mysqld"]
docker build -t honsen/mariadb .
docker images|grep honsen/
2)上传定制的MariaDB镜像至企业镜像仓库
docker tag honsen/mariadb <企业镜像仓库地址>:5000/honsen_mariadb
docker push <企业镜像仓库地址>:5000/honsen_mariadb
3)导入定制的MariaDB镜像，生成OpenShiftImage Stream
oc import-image <企业镜像仓库地址>:5000/honsen_mariadb -n openshift --confirm
2.定制Redis镜像，指定镜像的时区为中国
【注】缺省的Redis镜像的时区与中国时区差8小时
1)定制Redis镜像
远程登录master节点，执行:

MAINTAINERApollo.Yang
COPY./localtime /etc/localtime
#This default user is created in the openshift/base-centos7 image
USER1001
#Set the default port for applications built using this image
EXPOSE6379
#Set the default CMD for the image
CMD["run-redis"]
docker build -t honsen/redis .
docker images|grep honsen/
2)上传定制的Redis镜像至企业镜像仓库
docker tag honsen/redis <企业镜像仓库地址>:5000/honsen_redis
docker push <企业镜像仓库地址>:5000/honsen_redis

apiVersion:v1
kind:PersistentVolumeClaim
metadata:
name: redis
spec:
accessModes:
- ReadWriteOnce
selector:
matchLabels:
data: redis
resources:
requests:
storage: 2Gi
4)本地电脑创建honsen-pvc-user-icon.yaml
apiVersion:v1
kind:PersistentVolumeClaim
metadata:

file: usericons
resources:
requests:
storage: 10Gi
