Azure DNS に Bind ゾーンファイルのインポートを試してみた

検証用の Bind ゾーンファイルを作成

bash

$ cat /etc/os-release | grep PRETTY_NAME
PRETTY_NAME="Ubuntu 22.04.1 LTS"

$ sudo apt install bind9

$ systemctl status named

$ cd /etc/bind

$ sudo cp db.empty db.example.jp

$ sudo sed -i 's/localhost/example.jp/g' db.example.jp

$ echo "@       IN      A       192.168.10.10" | sudo tee -a db.example.jp

$ cat db.example.jp
; BIND reverse data file for empty rfc1918 zone
;
; DO NOT EDIT THIS FILE - it is used for multiple zones.
; Instead, copy it, edit named.conf, and use that copy.
;
$TTL    86400
@       IN      SOA     example.jp. root.example.jp. (
                              1         ; Serial
                         604800         ; Refresh
                          86400         ; Retry
                        2419200         ; Expire
                          86400 )       ; Negative Cache TTL
;
@       IN      NS      example.jp.
@       IN      A       192.168.10.10

$ named-checkzone example.jp db.example.jp 
zone example.jp/IN: loaded serial 1
OK

検証用の Azure DNS を作成

bash

$ az network dns zone create \
  --resource-group mnrlabo-rg \
  --name example.jp

$ az network dns zone import \
  --resource-group mnrlabo-rg \
  --name example.jp \
  --file-name db.example.jp

In the future, zone name will be case insensitive.
== BEGINNING ZONE IMPORT: example.jp ==

(1/3) Imported 1 records of type 'soa' and name '@'
(2/3) Imported 1 records of type 'NS' and name '@'
(3/3) Imported 1 records of type 'a' and name '@'

== 3/3 RECORDS IMPORTED SUCCESSFULLY: 'example.jp' ==

$ az network dns zone export \
  --resource-group mnrlabo-rg \
  --name example.jp

; Exported zone file from Azure DNS
;      Zone name: example.jp
;      Resource Group Name: mnrlabo-rg

$ az network dns zone delete \
