在kubernetes集群里集成Apollo配置中心(3)之交付Apollo-portal至Kubernetes集群

1.执行apollo-portal数据库脚本

apollo-portal数据库脚本链接：https://raw.githubusercontent.com/ctripcorp/apollo/1.5.1/scripts/db/migration/portaldb/V1.0.0__initialization.sql

在mfyxw10.mfyxw.com主机上操作

(1)将apollo-portal数据库脚本下载回来

[root@mfyxw10 ~]# wget https://raw.githubusercontent.com/ctripcorp/apollo/1.5.1/scripts/db/migration/portaldb/V1.0.0__initialization.sql -O apolloportal.sql

(2)导入apollo-portal脚本

[root@mfyxw10 ~]# mysql -uroot -p < apolloportal.sql

(3)查看是否导入成功

[root@mfyxw10 ~]# mysql -uroot -p
MariaDB [(none)]> show databases;          #Apollo-portal的数据库名为：ApolloPortalDB

MariaDB [ApolloPortalDB]>

(4)ApolloPortal数据库授权

[root@mfyxw10 ~]# mysql -uroot -p
MariaDB [(none)]> grant INSERT,DELETE,UPDATE,SELECT on ApolloPortalDB.* to "apolloportal"@"192.168.80.%" identified by "123456";
MariaDB [(none)]>flush privileges;
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]>

(5)更新ApolloPortal数据表ServerConfig的Value

[root@mfyxw10 ~]# mysql -uroot -p

2.准备apollo-portal软件

在运维主机mfyxw50.mfyxw.com上操作

(1)下载apollo-portal软件

[root@mfyxw50 ~]# cd /opt/src/
[root@mfyxw50 ~]# wget https://github.com/ctripcorp/apollo/releases/download/v1.5.1/apollo-portal-1.5.1-github.zip

(2)解压apollo-portal软件至相对应的目录

[root@mfyxw50 ~]# mkdir /data/dockerfile/apollo-portal
[root@mfyxw50 ~]# unzip /opt/src/apollo-portal-1.5.1-github.zip -d /data/dockerfile/apollo-portal

(3)删除apollo-portal目录用不到的文件

[root@mfyxw50 ~]# rm -fr /data/dockerfile/apollo-portal/apollo-portal-1.5.1-sources.jar
[root@mfyxw50 ~]# rm -fr /data/dockerfile/apollo-portal/apollo-portal.conf
[root@mfyxw50 ~]# rm -fr /data/dockerfile/apollo-portal/scripts/shutdown.sh

(4)配置数据库连接串

[root@mfyxw50 ~]# cat > /data/dockerfile/apollo-portal/config/application-github.properties << EOF
# DataSource
spring.datasource.url = jdbc:mysql://mysql.od.com:3306/ApolloPortalDB?characterEncoding=utf8
spring.datasource.username = apolloconfig
spring.datasource.password = 123456
EOF

(5)配置Portal的mate service(此处可以不修改，在configmap处已经引入了)

[root@mfyxw50 ~]# cat > /data/dockerfile/apollo-portal/config/apollo-env.properties << EOF
local.meta=http://localhost:8080
dev.meta=http://config.od.com:8080

uat.meta=http://fill-in-uat-meta-server:8080
lpt.meta=${lpt_meta}
pro.meta=http://fill-in-pro-meta-server:8080
EOF

(6)更新apollo-portal的startup.sh文件

[root@mfyxw50 ~]# cat > /data/dockerfile/apollo-portal/scripts/startup.sh << EOF

then
    echo "\$(date) Failed to start \$SERVICE_NAME.jar, return code: \$rc"
    exit \$rc;
fi
tail -f /dev/null
EOF

3.制作Apollo-Portal的Docker镜像

在运维主机(mfyxw50.mfyxw.com)上操作

(1)编写Apollo-Portal的Docker文件

[root@mfyxw50 ~]# cat > /data/dockerfile/apollo-portal/Dockerfile << EOF
FROM harbor.od.com/base/jre8:8u112
ENV VERSION 1.5.1
RUN ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime &&\
    echo "Asia/Shanghai" > /etc/timezone
ADD apollo-portal-\${VERSION}.jar /apollo-portal/apollo-portal.jar
ADD config/ /apollo-portal/config
ADD scripts/ /apollo-portal/scripts
CMD ["/apollo-portal/scripts/startup.sh"]
EOF

(2)制作Apollo-portal镜像

[root@mfyxw50 ~]# cd /data/dockerfile/apollo-portal
[root@mfyxw50 apollo-portal]# docker build . -t harbor.od.com/infra/apollo-portal:v1.5.1
[root@mfyxw50 apollo-portal]# docker login harbor.od.com
[root@mfyxw50 apollo-portal]# docker push harbor.od.com/infra/apollo-portal:v1.5.1

4.解析portal.od.com域名

在mfyxw10.mfyxw.com主机操作

(1)设置域名

[root@mfyxw10 ~]# cat > /var/named/od.com.zone << EOF
\$ORIGIN od.com.
\$TTL 600   ; 10 minutes
@       IN  SOA dns.od.com.   dnsadmin.od.com. (

EOF

(2)重启DNS服务

[root@mfyxw10 ~]# systemctl restart named

(3)测试解析

[root@mfyxw10 ~]# dig -t A portal.od.com @192.168.80.10 +short
192.168.80.100

5.准备Apollo-portal资源配置文件

EOF

6.应用Apollo-portal资源配置清单

在master节点(mfyxw30.mfyxw.com或mfyxw40.mfyxw.com)任意一台上执行即可

(1)应用Apollo-portal资源配置清单

[root@mfyxw30 ~]# kubectl apply -f http://k8s-yaml.od.com/apollo-portal/deployment.yaml
deployment.extensions/apollo-portal created
[root@mfyxw30 ~]#
[root@mfyxw30 ~]# kubectl apply -f http://k8s-yaml.od.com/apollo-portal/service.yaml
service/apollo-portal created
[root@mfyxw30 ~]#
[root@mfyxw30 ~]# kubectl apply -f http://k8s-yaml.od.com/apollo-portal/Ingress.yaml
ingress.extensions/apollo-portal created
[root@mfyxw30 ~]#
[root@mfyxw30 ~]# kubectl apply -f http://k8s-yaml.od.com/apollo-portal/configmap.yaml
configmap/apollo-portal-cm created

(2)查看Apollo-portal的pod是否正常启动

[root@mfyxw30 ~]# kubectl get pod -n infra
