Kubernetesda ilovalarni joylashtirishning qanday usullari mavjud va buning uchun qanday qadamlar bajarilishi kerak?

Kubernetesda ilovalarni joylashtirish odatda Application turiga qarab Deployment, StatefulSet yoki DaemonSet ob'ektlari yordamida amalga oshiriladi.

Joylashtirish uchun asosiy bosqichlar:

1. Docker tasvirini tayyorlash: Ilova tasvirini qurish va uni registrga yuklash (Docker Hub, shaxsiy registr).
2. Kubernetes manifestlarini yozish: Deployment, Service va boshqa zarur resurslarni tavsiflovchi YAML fayllarini yaratish.
3. Manifestlarni qo'llash: kubectl apply -f <fayl> buyrug'ini ishlatib, resurslarni klasterda yaratish.
4. Monitoring va boshqarish: Podlarning holatini tekshirish, loglarni ko'rish va kerak bo'lsa, ilovani kengaytirish.

Oddiy Deployment misoli:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: myapp-deployment
spec:
  replicas: 3
  selector:
    matchLabels:
      app: myapp
  template:
    metadata:
      labels:
        app: myapp
    spec:
      containers:
      - name: myapp-container
        image: myregistry/myapp:latest
        ports:
        - containerPort: 8080

Keyin, ilovaga kirish uchun Service yaratish mumkin.
