Dokumen ini menjelaskan cara mengirim notifikasi anggaran ke Slack.
Anggaran
biasanya dikonfigurasi untuk mengirim notifikasi email. Namun, email tidak selalu menjadi cara terbaik untuk mendapatkan informasi terbaru tentang biaya cloud Anda, terutama jika anggaran Anda sangat penting dan sensitif terhadap waktu. Dengan notifikasi terprogram,
Anda dapat meneruskan pesan anggaran ke media lain, seperti
Slack.
Sebelum memulai
Sebelum memulai, Anda harus menyelesaikan tugas berikut:
Langkah pertama adalah membuat ruang kerja Slack Anda dan token pengguna bot
yang digunakan untuk memanggil Slack API. Token API dapat dikelola di
https://api.slack.com/apps.
Untuk petunjuk detailnya, lihat
Pengguna Bot
di situs Slack.
Menyiapkan fungsi Cloud Run
Selesaikan langkah-langkah di
Membuat fungsi Cloud Run.
Pastikan Jenis pemicu ditetapkan ke topik Pub/Sub yang sama dengan yang akan digunakan oleh anggaran Anda.
Salin kode berikut ke fungsi Cloud Run Anda untuk memposting
notifikasi anggaran ke saluran chat Slack menggunakan Slack API:
Node.js
constslack=require('slack');// TODO(developer) replace these with your own valuesconstBOT_ACCESS_TOKEN=process.env.BOT_ACCESS_TOKEN||'xxxx-111111111111-abcdefghidklmnopq';constCHANNEL=process.env.SLACK_CHANNEL||'general';exports.notifySlack=asyncpubsubEvent=>{constpubsubAttrs=pubsubEvent.attributes;constpubsubData=Buffer.from(pubsubEvent.data,'base64').toString();constbudgetNotificationText=`${JSON.stringify(pubsubAttrs)}, ${pubsubData}`;awaitslack.chat.postMessage({token:BOT_ACCESS_TOKEN,channel:CHANNEL,text:budgetNotificationText,});return'Slack notification sent successfully';};
Python

Pastikan parameter postMessage Slack API berikut disetel dengan benar:
Token akses OAuth Pengguna Bot
Nama saluran
Menguji fungsi
Untuk memastikan fungsi Anda berfungsi seperti yang diharapkan, ikuti langkah-langkah di
Menguji fungsi Cloud Run.
Jika berhasil, pesan akan muncul di Slack.

However, email isn't\nalways the best way to stay up to date on your cloud costs, particularly if\nyour budget is critical and time sensitive. With programmatic notifications,\nyou can forward your budget messages to other mediums, such as\n[Slack](https://slack.com/).\n\nBefore you begin\n----------------\n\nBefore you begin, you must complete the following tasks:\n\n1. [Enable the Cloud Billing API](https://console.cloud.google.com/apis/api/cloudbilling.googleapis.com)\n2. [Create a budget](/billing/docs/how-to/budgets)\n3. [Set up programmatic budget notifications](/billing/docs/how-to/budgets-programmatic-notifications)\n\nSet up a Slack channel and permissions\n--------------------------------------\n\nThe first step is to create your Slack workspace and the bot user tokens\nthat are used to call the Slack API. API tokens can be managed at\n\u003chttps://api.slack.com/apps\u003e.\nFor detailed instructions, see\n[Bot Users](https://api.slack.com/bot-users)\non the Slack site.\n\nSet up a Cloud Run function\n---------------------------\n\n1. Complete the steps in\n [Create a Cloud Run function](/billing/docs/how-to/listen-to-notifications#create-function).\n Ensure that the **Trigger type** is set to the same Pub/Sub\n topic that your budget will use.\n\n2. Add the following dependencies:\n\n\n ### Node.js\n\n \u003cbr /\u003e\n\n Copy the following to your `package.json`:\n\n\n {\n \"name\": \"cloud-functions-billing\",\n \"private\": \"true\",\n \"version\": \"0.0.1\",\n \"description\": \"Examples of integrating Cloud Functions with billing\",\n \"main\": \"index.js\",\n \"engines\": {\n \"node\": \"\u003e=16.0.0\"\n },\n \"scripts\": {\n \"compute-test\": \"c8 mocha -p -j 2 test/periodic.test.js --timeout=600000\",\n \"test\": \"c8 mocha -p -j 2 test/index.test.js --timeout=5000 --exit\"\n },\n \"author\": \"Ace Nassri \u003canassri@google.com\u003e\",\n \"license\": \"Apache-2.0\",\n \"dependencies\": {\n \"@google-cloud/billing\": \"^4.0.0\",\n \"@google-cloud/compute\": \"^4.0.0\",\n \"google-auth-library\": \"^9.0.0\",\n \"googleapis\": \"^143.0.0\",\n \"slack\": \"^11.0.1\"\n },\n \"devDependencies\": {\n \"@google-cloud/functions-framework\": \"^3.0.0\",\n \"c8\": \"^10.0.0\",\n \"gaxios\": \"^6.0.0\",\n \"mocha\": \"^10.0.0\",\n \"promise-retry\": \"^2.0.0\",\n \"proxyquire\": \"^2.1.0\",\n \"sinon\": \"^18.0.0\",\n \"wait-port\": \"^1.0.4\"\n }\n }\n\n ### Python\n\n \u003cbr /\u003e\n\n Copy the following to your `requirements.txt`:\n\n\n slackclient==2.9.4\n google-api-python-client==2.131.0\n\n \u003cbr /\u003e\n\n3. Copy the following code into your Cloud Run function to post\n budget notifications to a Slack chat channel using the Slack API:\n\n\n ### Node.js\n\n const slack = require('slack');\n\n // TODO(developer) replace these with your own values\n const BOT_ACCESS_TOKEN =\n process.env.BOT_ACCESS_TOKEN || 'xxxx-111111111111-abcdefghidklmnopq';\n const CHANNEL = process.env.SLACK_CHANNEL || 'general';\n\n exports.notifySlack = async pubsubEvent =\u003e {\n const pubsubAttrs = pubsubEvent.attributes;\n const pubsubData = Buffer.from(pubsubEvent.data, 'base64').toString();\n const budgetNotificationText = `${JSON.stringify(\n pubsubAttrs\n )}, ${pubsubData}`;\n\n await slack.chat.postMessage({\n token: BOT_ACCESS_TOKEN,\n channel: CHANNEL,\n text: budgetNotificationText,\n });\n\n return 'Slack notification sent successfully';\n };\n\n ### Python\n\n import base64\n import json\n import os\n import slack\n from slack.errors import SlackApiError\n # See https://api.slack.com/docs/token-types#bot for more info\n BOT_ACCESS_TOKEN = \"xxxx-111111111111-abcdefghidklmnopq\"\n CHANNEL = \"C0XXXXXX\"\n\n slack_client = slack.WebClient(token=BOT_ACCESS_TOKEN)\n\n\n def notify_slack(data, context):\n pubsub_message = data\n\n # For more information, see\n # https://cloud.google.com/billing/docs/how-to/budgets-programmatic-notifications#notification_format\n try:\n notification_attr = json.dumps(pubsub_message[\"attributes\"])\n except KeyError:\n notification_attr = \"No attributes passed in\"\n\n try:\n notification_data = base64.b64decode(data[\"data\"]).decode(\"utf-8\")\n except KeyError:\n notification_data = \"No data passed in\"\n\n # This is just a quick dump of the budget data (or an empty string)\n # You can modify and format the message to meet your needs\n budget_notification_text = f\"{notification_attr}, {notification_data}\"\n\n try:\n slack_client.api_call(\n \"chat.postMessage\",\n json={\"channel\": CHANNEL, \"text\": budget_notification_text},\n )\n except SlackApiError:\n print(\"Error posting to Slack\")\n\n \u003cbr /\u003e\n\n4. Ensure the following Slack API postMessage parameters are set correctly:\n\n - Bot User OAuth access token\n - Channel name\n\nTest your function\n------------------\n\nTo ensure your function works as expected, follow the steps in\n[Test a Cloud Run function](/billing/docs/how-to/listen-to-notifications#test-function).\n\nIf successful, a message will show up in Slack.\n\nWhat's next\n-----------\n\nReview other programmatic notification examples to learn how to do the\nfollowing:\n\n- [Listen to your notifications](/billing/docs/how-to/listen-to-notifications)\n- [Control resource usage with notifications](/billing/docs/how-to/control-usage)\n- [Disable billing usage with notifications](/billing/docs/how-to/disable-billing-with-notifications)"]]
