10 Worker Queue

Αυτό το lab παρουσιάζει μια μικρή αρχιτεκτονική Queue με Redis, Producer Job, Worker Deployment, PDB, HPA και NetworkPolicies.

Έλεγχος

bash
kubectl apply --dry-run=client -f manifests/
01 / 04

Εκτέλεση

bash
kubectl apply -f manifests/
kubectl rollout status deployment/redis -n queue-lab
kubectl rollout status deployment/queue-worker -n queue-lab
kubectl wait --for=condition=complete job/queue-producer -n queue-lab --timeout=120s
kubectl logs -n queue-lab job/queue-producer
kubectl logs -n queue-lab deployment/queue-worker --tail=20

Αυξήστε τα Worker replicas και προσθέστε ξανά εργασίες στην Queue:

bash
kubectl scale deployment queue-worker -n queue-lab --replicas=4
kubectl create job queue-producer-again --from=job/queue-producer -n queue-lab
kubectl logs -n queue-lab deployment/queue-worker --tail=50
02 / 04

Σημεία μάθησης

  • Ο Producer και οι Workers λειτουργούν ανεξάρτητα.
  • Το Redis χρησιμοποιείται εδώ μόνο ως απλή Queue και δεν αποτελεί production HA βάση δεδομένων.
  • Μπορείτε να αυξήσετε οριζόντια τα Worker replicas.
  • Το HPA απαιτεί Metrics Server.
  • Οι NetworkPolicies επιτρέπουν πρόσβαση στο Redis μόνο από τον Producer και τους Workers.
