במאמר הזה נסביר איך לשלוח התראות לגבי תקציבים ל-Slack.
בדרך כלל, התראות לגבי תקציבים מוגדרים לשליחה באימייל. אבל אימייל הוא לא תמיד הדרך הטובה ביותר להתעדכן בעלויות בענן, במיוחד אם מדובר בתקציב קריטי שבו גם הזמן חשוב. בעזרת התראות פרוגרמטיות, אתם יכולים להעביר את ההודעות לגבי התקציבים לאמצעי תקשורת אחרים, כמו Slack.
בשלב הראשון יוצרים את סביבת העבודה ב-Slack ואת אסימוני המשתמשים שמשמשים את הבוטים כדי לשלוח קריאה ל-Slack API. אסימוני ה-API מנוהלים בכתובת https://api.slack.com/apps.
תוכלו להיעזר בהוראות שבמאמר Bot Users באתר Slack.
הגדרת פונקציית Cloud Run
אתם יכולים להיעזר בהוראות שבמאמר יצירה של פונקציית Cloud Run.
חשוב לוודא שהגדרתם את Trigger type כך שישתמש באותו נושא Pub/Sub שהוגדר לשימוש בתקציב.
מעתיקים את הקוד הבא לפונקציית Cloud Run כדי לפרסם התראות לגבי תקציבים בערוץ הצ'אט ב-Slack באמצעות Slack API:
Node.js

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.
