参考架构
一个集成其他dns的参考玩法
集成示例
基于docker-compose 运行
- docker-compose.yaml
version: "3"
services:
pdnsadmin:
image: powerdnsadmin/pda-legacy:0.3
networks:
dns:
ipv4_address: 172.16.238.9
ports:
- 80:80
environment:
- PDNS_API_KEY=a_strong_api_key
- PDNS_STATS_URL=http://pdns:8081
- PDNS_API_URL=http://pdns:8081
- PDNS_VERSION=4.6.2
pdns:
image: interlegis/powerdns:4.6.2
networks:
dns:
ipv4_address: 172.16.238.10
ports:
- 3053:53
- 3053:53/udp
- 8081:8081
environment:
- PDNSCONF_API_KEY=a_strong_api_key
- PDNSCONF_DNSUPDATE=yes
- SECALLZONES_CRONJOB=yes
- PDNSCONF_GMYSQL_USER=root
- PDNSCONF_GMYSQL_DBNAME=powerdns
- PDNSCONF_GMYSQL_PASSWORD=dalong
coredns:
image: dalongrong/coredns
command: -conf=/opt/Corefile
networks:
dns:
ipv4_address: 172.16.238.11
volumes:
- ./Corefile:/opt/Corefile
ports:
- 2053:53
- 2053:53/udp
mysql:
image: mysql:8.0.32
command: --default-authentication-plugin=mysql_native_password --log-bin --binlog-format=ROW --character-set-server=utf8mb4 --collation-server=utf8mb4_unicode_ci
networks:
dns:
ipv4_address: 172.16.238.12
environment:
- MYSQL_ROOT_PASSWORD=dalong
- MYSQL_DATABASE=powerdns
ports:
- 3306:3306
app:
image: pymumu/smartdns:latest
networks:
dns:
ipv4_address: 172.16.238.13
volumes:
- ./smartdns:/etc/smartdns
ports:
- 1053:53/udp
- 1053:53/tcp
networks:
dns:
driver: bridge
ipam:
driver: default
config:
- subnet: 172.16.238.0/24
- coredns 配置
.:53 {
mysql {
dsn root:dalong@tcp(mysql:3306)/powerdns?tls=skip-verify&autocommit=true
ttl 20
}
}
- smartdns 配置
此服务包含了转发coredns 以及powerdns 的配置
bind [::]:53
server 8.8.8.8
server 1.222.1.1
server 172.16.238.11
server 172.16.238.10
server 114.114.114.114
audit-enable yes
cache-size 32768
rr-ttl 5
cache-persist yes
prefetch-domain yes
log-level debug
log-console yes
cache-file /var/cache/file
serve-expired-prefetch-time 0
address /example.com/1.2.3.4
address /example.com/4.5.6.7,8.9.10.11,12.13.14.15,113.156.178.1
cname /dalong.com/example.com
ip-alias 1.2.3.4/32 192.168.1.1
- 启动
docker-compose up -d
注意启动之后需要创建coredns 的记录表，powerdns 就不需要
CREATE TABLE `coredns_records` (
`id` INT NOT NULL AUTO_INCREMENT,
`zone` VARCHAR(255) NOT NULL,
`name` VARCHAR(255) NOT NULL,
`ttl` INT DEFAULT NULL,
`content` TEXT,
`record_type` VARCHAR(255) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE = INNODB AUTO_INCREMENT = 6 DEFAULT CHARSET = utf8mb4 COLLATE = utf8mb4_0900_ai_ci;
配置powerdns admin 以及添加coredns 记录
添加记录
coredns 记录
INSERT INTO coredns_records (zone, name, ttl, content, record_type) VALUES
('appdemo.org.', 'foo', 30, '{"ip": "1.1.1.1"}', 'A')
- 查询效果
说明
基于smartdns 提供的一些能力以及利用一些开源dns server 可以实现比较灵活的dns 控制，完整的示例我已经push 到github 了，可以参考
