Your company runs a containerized microservices application on Google Kubernetes Engine (GKE) with a regional cluster. The application consists of a frontend service, a backend API service, and a background worker service that processes messages from Cloud Pub/Sub. The worker service uses a Deployment with 3 replicas. Recently, the team noticed that the worker service is frequently failing with 'ContainerCreating' errors. The error message in the pod events is: 'Failed to pull image "gcr.io/my-project/my-worker:latest": rpc error: code = DeadlineExceeded desc = context deadline exceeded'. The image is stored in Container Registry in the same project. The cluster nodes are n1-standard-2 VMs with 10 GB of disk space.

A company runs multiple microservices on Cloud Run. Each service uses a Serverless VPC Access connector to connect to a shared Cloud Memorystore for Redis instance (standard tier) in a VPC network. The Redis instance is configured with a firewall rule that allows TCP connections on port 6379 from the VPC connector's subnet (10.8.0.0/28). After a recent code update, the order-service fails to connect to Redis, while the user-service continues to work. The error logs in order-service show 'connection refused'.
