Google Cloud DNS使用記錄


DNS是網際網路服務上不可或缺的一項服務，Google Cloud Platform上當壖也不能缺少這個服務... 果然在今年度問世了... 這邊介紹整個操作與設定的過程...

Zone的管理

建立DNS Zone


peixindeMacBook-Pro in ~/Downloads
○ → gcloud dns managed-zone create --dns_name="gcp.arecord.us." --description="A zone" "gcp-arecord-us"
Creating {'dnsName': 'gcp.arecord.us.', 'name': 'gcp-arecord-us',
'description': 'A zone'} in easelifes-gcp-project

Do you want to continue (Y/n)?  Y

{
   "creationTime": "2014-04-24T11:32:03.853Z",
   "description": "A zone",
   "dnsName": "gcp.arecord.us.",
   "id": "1595320562141013743",
   "kind": "dns#managedZone",
   "name": "gcp-arecord-us",
   "nameServers": [
   ]
}

檢視Zone是否建立完成


peixindeMacBook-Pro in ~/Downloads
○ → gcloud dns managed-zone list
[
   {
       "creationTime": "2014-04-24T11:32:03.853Z",
       "description": "A zone",
       "dnsName": "gcp.arecord.us.",
       "id": "1595320562141013743",
       "kind": "dns#managedZone",
       "name": "gcp-arecord-us",
       "nameServers": [

           "ns-cloud-d2.googledomains.com.",
           "ns-cloud-d3.googledomains.com.",
           "ns-cloud-d4.googledomains.com."
       ]
   }
]

檢視某個特定Zone下的記錄


peixindeMacBook-Pro in ~/Downloads
○ → gcloud dns managed-zone get gcp-arecord-us
{
   "creationTime": "2014-04-24T11:32:03.853Z",
   "description": "A zone",
   "dnsName": "gcp.arecord.us.",
   "id": "1595320562141013743",
   "kind": "dns#managedZone",
   "name": "gcp-arecord-us",
   "nameServers": [
   ]
}

Record管理

檢視DNS Zone下的記錄(record)


peixindeMacBook-Pro in ~/Downloads
○ → gcloud dns records --zone="gcp-arecord-us" list
[
   {
       "kind": "dns#resourceRecordSet",
       "name": "gcp.arecord.us.",
       "rrdatas": [
           "ns-cloud-d1.googledomains.com.",
           "ns-cloud-d2.googledomains.com.",
           "ns-cloud-d3.googledomains.com.",
           "ns-cloud-d4.googledomains.com."
       ],
       "ttl": 21600,
       "type": "NS"
   },
   {
       "kind": "dns#resourceRecordSet",
       "name": "gcp.arecord.us.",
       "rrdatas": [
           "ns-cloud-d1.googledomains.com. dns-admin.google.com. 0 21600 3600 1209600 300"
       ],
       "ttl": 21600,
       "type": "SOA"
   }
]


編輯DNS記錄

插曲 - 安裝textmate並且設定至路徑




Mac的用戶，可以下載TextMate：http://macromates.com/，並安裝至Application folder，然後透過下面指令將mate link到/usr/bin/mate

$ sudo ln -s /Applications/TextMate.app/Contents/SharedSupport/Support/bin/mate /usr/bin/mate

其中，mate需要安裝1.5.11版本，才可以在路徑中找到mate德執行檔... 安裝完之後，再執行一次上面指令，就可以正常編輯DNS記錄檔案...



編輯好後，儲存並關閉，則console會跳轉到執行結束畫面，執行結束會列表目前的record設定狀況，因此在這邊就可以看到剛剛所增加的設定值。

測試記錄是否寫入


要確認record是否正常寫入，可以透過gcloud dns records list的方式列表...

peixindeMacBook-Pro in ~
○ → gcloud dns records --zone="gcp-arecord-us" list
[
   {
       "kind": "dns#resourceRecordSet",
       "name": "gcp.arecord.us.",
       "rrdatas": [
           "ns-cloud-d1.googledomains.com.",
           "ns-cloud-d2.googledomains.com.",
           "ns-cloud-d3.googledomains.com.",
           "ns-cloud-d4.googledomains.com."
       ],
       "ttl": 21600,
       "type": "NS"
   },
   {
       "kind": "dns#resourceRecordSet",
       "name": "gcp.arecord.us.",
       "rrdatas": [
           "ns-cloud-d1.googledomains.com. dns-admin.google.com. 1 21600 3600 1209600 300"
       ],
       "ttl": 21600,
       "type": "SOA"
   },
   {
       "kind": "dns#resourceRecordSet",
       "name": "www.gcp.arecord.us.",
       "rrdatas": [
           "192.168.2.10"
       ],
       "ttl": 86400,
       "type": "A"
   }
]

檢視DNS是否設定完成


確認好令表正確之後，接下來可以確認一下記錄是否已經生效...

peixindeMacBook-Pro in ~
Address: 216.239.32.109#53

Address: 192.168.2.10

後續


到這邊為止，記錄雖然已經生效，但是還無法讓網際網路上的大眾找到您的記錄，所剩的臨門一腳是～將DNS記錄指向到適當的DNS server位置，如果需要找DNS server位置，可以透過下面指令：

peixindeMacBook-Pro in ~
○ → gcloud dns managed-zone get gcp-arecord-us
{
   "creationTime": "2014-04-24T11:32:03.853Z",
   "description": "A zone",
   "dnsName": "gcp.arecord.us.",
   "id": "1595320562141013743",
   "kind": "dns#managedZone",
   "name": "gcp-arecord-us",
   "nameServers": [
   ]
}

其中nameServers的位置，設定到網域提供商所指定的DNS name server位置即可，而如果您設定的是subdomain，則透過指定NS record即可完成設定，下面是godaddy subdomain的記錄設定範例：


設定完成後，等待一段時間，重新確認DNS記錄：

peixindeMacBook-Pro in ~
○ → nslookup www.gcp.arecord.us
Server: 168.95.1.1
Address: 168.95.1.1#53

Non-authoritative answer:
Address: 192.168.2.10

透過Google Apps Script結合Google Form做即時郵件通知

體驗過Google Apps Script的功能後，也發現他結合GmailApps的模組 GmailApps的應用可以用在表單填寫完成後，做發信的通知 例如您開立了一個訂購的表單，為了要在第一時間通知商家有訂單進入 就可以直接呼叫Gmail做發信的通知，讓手持Smart Phone的我們可以很快的知道生意上門了！ 下面規劃三個function，其中： onCommit()：為form commit時候觸發的function，需要掛載於form commit trigger上 jsonArrToTable()：目的將json array解析成為一個Table getLastRowTable()：目的將整個table的回傳過濾為剩下第一筆(表頭，含有Form的欄位說明)與最後一筆(原則上就是剛剛送出的那一筆表單) 完整程式碼如下： function onCommit(){   var sheet = SpreadsheetApp.getActiveSheet();   var rows = sheet.getDataRange();   var numRows = rows.getNumRows();   var values = rows.getValues();   var content = getLastRowTable(values);   var htmlBody = "Hi Admin: <br/><br/>有訂單拉，檢查一下吧！ <br/><br/>" + content + '<br/><br/>Send by Google Apps';   GmailApp.sendEmail(     " your-email-address@gmail.com ",      "Order Confirm Notice",      htmlBody,      {from: ' from-email-...
