Configuration example

For more configuration items, please refer to the coredns official website. For example, we give a general example:

.:53 {
    loadbalance round_robin
    # Load zones records from local /etc/hosts.
    hosts {
        fallthrough
    }
    # Load zones records from redis-cluster(default settings).
    coredns_gdns {

Reverse resolution

Currently does not support direction resolution

Proxy resolution

Currently does not support direction resolution

Zones resolving records are stored in redis-cluster data format

Each zone is stored as a hash map in redis-cluster, with zone as the key. Note: According to the https://tools.ietf.org/html/rfc6763 protocol, it ends with a "." suffix. Such as:

redis-cli>KEYS *
1) "example.com."
2) "example.net."
redis-cli>
dns RRs

Stored in redis cluster in json string format, @ is used for RR value of the region itself. Such as:

A
{
    "a":{
        "ip": "1.2.3.4",
        "ttl": 360
    }
}
AAAA
{
    "aaaa":{
        "ip": "::1",
        "ttl": 360
    }
}
CNAME
{
    "cname":{
        "host": "x.example.com.",
        "ttl": 360
    }
}
TXT
{
    "TXT":{
        "text": "this is a text",
        "ttl": 360
    }
}
NS
{
    "ns":{
        "host": "ns1.example.com.",
        "ttl": 360
    }
}
MX
{
    "mx":{
        "host": "mx1.example.com",
        "priority": 10,
        "ttl": 360
    }
}
SRV
{
    "srv":{
        "host": "sip.example.com.",
        "port": 555,
        "priority": 10,
        "weight": 100,
        "ttl": 360
    }
}
SOA
{
    "soa":{
        "ttl": 100,
        "mbox": "hostmaster.example.com.",
        "ns": "ns1.example.com.",
        "refresh": 44,
        "retry": 55,
        "expire": 66
    }
}

}

Parsing example

$ORIGIN example.net.
 example.net. 300 IN SOA <SOA RDATA>
 example.net. 300 NS ns1.example.net.
 example.net. 300 NS ns2.example.net.
 *.example.net. 300 TXT "this is a wildcard"
 *.example.net. 300 MX 10 host1.example.net.
 sub.*.example.net. 300 TXT "this is not a wildcard"
 host1.example.net. 300 A 5.5.5.5
 _ssh.tcp.host1.example.net. 300 SRV <SRV RDATA>
 _ssh.tcp.host2.example.net. 300 SRV <SRV RDATA>
 subdel.example.net. 300 NS ns1.subdel.example.net.
 subdel.example.net. 300 NS ns2.subdel.example.net.
 host2.example.net CAA 0 issue "letsencrypt.org"

The above zone data should be stored in redis-cluster as follows:

redis-cli> hgetall example.net.
 1) "_ssh._tcp.host1"
 2) "{\"srv\":[{\"ttl\":300, \"target\":\"tcp.example.com.\",\"port\":123,\"priority\" :10,\"weight\":100}]}"
 3) "*"
 4) "{\"txt\":[{\"ttl\":300, \"text\":\"this is a wildcard\"}],\"mx\":[{\"ttl\" :300, \"host\":\"host1.example.net.\",\"preference\": 10}]}"
 5) "host1"
 6) "{\"a\":[{\"ttl\":300, \"ip\":\"5.5.5.5\"}]}"
 7) "sub.*"
 8) "{\"txt\":[{\"ttl\":300, \"text\":\"this is not a wildcard\"}]}"
 9) "_ssh._tcp.host2"
10) "{\"srv\":[{\"ttl\":300, \"target\":\"tcp.example.com.\",\"port\":123,\"priority\" :10,\"weight\":100}]}"
11) "subdel"
12) "{\"ns\":[{\"ttl\":300, \"host\":\"ns1.subdel.example.net.\"},{\"ttl\":300, \ "host\":\"ns2.subdel.example.net.\"}]}"

var SpecialDomains = [...]string{"com.cn.", "net.cn.", ".ac.cn.", ".org.cn.", ".gov.cn.", ".mil.cn.", ".edu.cn."}

Some special top-level domain names are defined here, because they have two levels of top-level names, which need special treatment when dealing with DNS query.
