מניעת מחיקה לא מכוונת של מכונות וירטואליות

במאמר הזה נסביר איך להגן על מכונות וירטואליות ספציפיות מפני מחיקה על ידי הגדרת המאפיין deletionProtection במשאב Instance. מידע נוסף על מופעי VM זמין במאמר בנושא מופעים.

יכול להיות שחלק מהמכונות הווירטואליות בעומס העבודה שלכם קריטיות להרצת האפליקציה או השירותים, כמו מכונה וירטואלית שמריצה שרת SQL, שרת שמשמש כמנהל רישיונות וכו'. יכול להיות שיהיה צורך להשאיר את מופעי מכונות ה-VM האלה פועלים ללא הגבלת זמן, ולכן צריך דרך להגן על מכונות ה-VM האלה מפני מחיקה.

הגדרת הדגל deletionProtection מאפשרת להגן על מופע של מכונה וירטואלית מפני מחיקה לא מכוונת. אם משתמש מנסה למחוק מופע של מכונה וירטואלית (VM) שהגדרתם עבורה את הדגל deletionProtection, הבקשה נכשלת. רק משתמש שהוקצה לו תפקיד עם הרשאה compute.instances.create יכול לאפס את הדגל כדי לאפשר את מחיקת המשאב.

לפני שמתחילים

מפרטים

  • מניעת מחיקה לא מונעת את הפעולות הבאות:

  • אפשר להחיל הגנה מפני מחיקה גם על מכונות וירטואליות רגילות וגם על מכונות וירטואליות מסוג Preemptible VM.

  • אי אפשר להחיל הגנה מפני מחיקה על מכונות וירטואליות ששייכות לקבוצת מופעים מנוהלת, אבל אפשר להחיל אותה על מופעים ששייכים לקבוצות מופעים לא מנוהלות.

  • אי אפשר לציין מניעת מחיקה בתבניות של מופעים.

הרשאות

כדי לבצע את המשימה הזו, אתם צריכים את ההרשאות הבאות או אחד מתפקידי ה-IAM הבאים במשאב.

הרשאות

  • compute.instances.create

תפקידים

  • compute.admin
  • compute.instanceAdmin.v1

הגדרת הגנה מפני מחיקה במהלך יצירת מופע

כברירת מחדל, ההגנה מפני מחיקה מושבתת במופע שלכם. כדי להפעיל את ההגנה מפני מחיקה, פועלים לפי ההוראות שבהמשך.

המסוף

  1. נכנסים לדף Create an instance במסוף Google Cloud .

    כניסה לדף Create an instance

  2. מרחיבים את הקטע אפשרויות מתקדמות ומבצעים את הפעולות הבאות:

    1. מרחיבים את הקטע ניהול.
    2. מסמנים את התיבה הגנה מפני מחיקה.

  3. ממשיכים בתהליך יצירת ה-VM.

gcloud

כשיוצרים מכונה וירטואלית, צריך לכלול את הדגלים --deletion-protection או no-deletion-protection. ההגנה מפני מחיקה מושבתת כברירת מחדל, לכן כדי להפעיל אותה:

gcloud compute instances create [INSTANCE_NAME] --deletion-protection

כאשר [INSTANCE_NAME] הוא השם של המופע הרצוי.

כדי להשבית את ההגנה מפני מחיקה במהלך היצירה:

gcloud compute instances create [INSTANCE_NAME] --no-deletion-protection

REST

ב-API, כשיוצרים מכונה וירטואלית, צריך לכלול את המאפיין deletionProtection בגוף הבקשה. לדוגמה:

POST https://compute.googleapis.com/compute/v1/projects/[PROJECT_ID]/zones/[ZONE]/instances

{
  "name": "[INSTANCE_NAME]",
  "deletionProtection": "true",
  ...
}

כדי להשבית את ההגנה מפני מחיקה, מגדירים את deletionProtection לערך false.

בדיקה אם ההגנה מפני מחיקה מופעלת במופע

אפשר לקבוע אם ההגנה מפני מחיקה מופעלת במופע ב-gcloud tool או ב-API.

המסוף

  1. נכנסים לדף VM instances.

    כניסה לדף VM instances

  2. אם מוצגת בקשה לעשות זאת, בוחרים פרויקט ולוחצים על המשך.

  3. בדף VM instances (מכונות וירטואליות), פותחים את התפריט Columns (עמודות) ומפעילים את האפשרות Deletion protection (הגנה מפני מחיקה).

    אפשרות למחיקת מכונה וירטואלית.

  4. עמודה חדשה מופיעה עם סמל ההגנה מפני מחיקה. אם ההגנה מפני מחיקה מופעלת במכונה וירטואלית, הסמל מופיע לצד שם המכונה.

gcloud

הפעלה או השבתה של הגנה מפני מחיקה במופעים קיימים

אפשר להפעיל או להשבית את ההגנה מפני מחיקה של מופע קיים, בלי קשר לסטטוס הנוכחי של המופע. במילים אחרות, לא צריך להפסיק את המופע כדי להפעיל או להשבית את ההגנה מפני מחיקה.

המסוף

  1. נכנסים לדף VM instances.

מריצים את הפקודה update באמצעות ה-CLI של gcloud עם הדגל --deletion-protection או --no-deletion-protection:

gcloud compute instances update [INSTANCE_NAME] \
