将AWS Router53 DNS 导出文件转换成兼容 BIND的区域文件并导入到Azure DNS
原创在某些场景中，需要将AWS上的DNS迁移到其他服务商，如Azure，Dodaddy，Cloudflare等，AWS导出的DNS区域文件为Json格式，需要将其将换成兼容 BIND 的区域文件格式（RFC1035）。
AWS DNS区域文件格式：
{
"ResourceRecordSets": [
{
"Name": "mooing.cc.",
"Type": "NS",
"TTL": 3600,
"ResourceRecords": [
{
"Value": "ns-590.awsdns-09.net."
},
{
"Value": "ns-1393.awsdns-46.org."
},
{
"Value": "ns-339.awsdns-42.com."
},
{
"Value": "ns-1767.awsdns-28.co.uk."
}
]
},
{
"Name": "test.mooing.cc.",
"Type": "A",
"TTL": 300,
"ResourceRecords": [
{
"Value": "1.1.1.1"
}
]
},
{
"Name": "test2.mooing.cc.",
"Type": "CNAME",
"TTL": 300,
"ResourceRecords": [
{
"Value": "www.baidu.com."
}
]
}
}
"ResourceRecordSets": [
{
"Name": "mooing.cc.",
"Type": "NS",
"TTL": 3600,
"ResourceRecords": [
{
"Value": "ns-590.awsdns-09.net."
},
{
"Value": "ns-1393.awsdns-46.org."
},
{
"Value": "ns-339.awsdns-42.com."
},
{
"Value": "ns-1767.awsdns-28.co.uk."
}
]
},
{
"Name": "test.mooing.cc.",
"Type": "A",
"TTL": 300,
"ResourceRecords": [
{
"Value": "1.1.1.1"
}
]
},
{
"Name": "test2.mooing.cc.",
"Type": "CNAME",
"TTL": 300,
"ResourceRecords": [
{
"Value": "www.baidu.com."
}
]
}
}
兼容 BIND 的区域文件格式（RFC1035）：
test.mooing.cc. 300 IN A 1.1.1.1
test2.mooing.cc. 300 IN CNAME www.baidu.com.
test2.mooing.cc. 300 IN CNAME www.baidu.com.
编写了一个脚本，供大家参考:
需要注意某些记录（如例子中的NS记录），可能对应多个值，所以需要用foreach循环进行遍历。
$FolderLocation="D:\Mooing\Domains" #设置AWS导出的Domain文件夹
$ZoneLocation="D:\Mooing\Zone" #设置转换后的文件夹
$Domains=Get-ChildItem $FolderLocation
foreach ($domain in $Domains)
{
cd $FolderLocation
$DomainName=Get-Content $FolderLocation\$domain -Raw | ConvertFrom-Json
$Records=$DomainName.ResourceRecordSets
foreach ($Record in $Records)
{
if ($Record.ResourceRecords.Count -eq 1)
{
$Record.Name + " " + $Record.ttl + " IN " + $Record.type + " " + $Record.ResourceRecords.Value.replace("\","") |Out-File $ZoneLocation\$domain.Zone.txt -Append utf8
}
else
{
$i=0
while($i -lt $Record.ResourceRecords.Count) {
$Record.Name + " " + $Record.ttl + " IN " + $Record.type + " " + $Record.ResourceRecords.Value[$i].replace("\","") |Out-File $ZoneLocation\$domain.Zone.txt -Append utf8
$i++
}
}
}
}
$ZoneLocation="D:\Mooing\Zone" #设置转换后的文件夹
$Domains=Get-ChildItem $FolderLocation
foreach ($domain in $Domains)
{
cd $FolderLocation
$DomainName=Get-Content $FolderLocation\$domain -Raw | ConvertFrom-Json
$Records=$DomainName.ResourceRecordSets
foreach ($Record in $Records)
{
if ($Record.ResourceRecords.Count -eq 1)
{
$Record.Name + " " + $Record.ttl + " IN " + $Record.type + " " + $Record.ResourceRecords.Value.replace("\","") |Out-File $ZoneLocation\$domain.Zone.txt -Append utf8
}
else
{
$i=0
while($i -lt $Record.ResourceRecords.Count) {
$Record.Name + " " + $Record.ttl + " IN " + $Record.type + " " + $Record.ResourceRecords.Value[$i].replace("\","") |Out-File $ZoneLocation\$domain.Zone.txt -Append utf8
$i++
}
}
}
}
转换完成之后，即可导入支持Bind格式的服务商，Azure导入方式请参考：
