NESCO Inc Interview Questions and Answers
Q1. How to make call from one namespace t another in AKS environment
To make a call from one namespace to another in AKS environment, use the fully qualified domain name (FQDN) of the service.
Use the FQDN of the service to make a call from one namespace to another in AKS environment
The FQDN should include the namespace and service name, for example: myservice.mynamespace.svc.cluster.local
Ensure that the service is exposed within the cluster and has a stable IP address
Use the appropriate network policies to allow traffic between namespaces if n...read more
Q2. How to divide AKS pods based on the load
AKS pods can be divided based on load using horizontal pod autoscaling (HPA) and cluster autoscaler.
Use HPA to automatically scale the number of replicas of a deployment based on CPU or memory usage.
Use cluster autoscaler to add or remove nodes from the AKS cluster based on the demand.
Use resource requests and limits to ensure that pods are scheduled on nodes with sufficient resources.
Consider using node selectors or affinity rules to ensure that pods are scheduled on nodes w...read more
Q3. How you handle container orchestration ?
I handle container orchestration using tools like Kubernetes and Docker Swarm.
Utilize Kubernetes for managing containerized applications
Use Docker Swarm for orchestrating containers across multiple hosts
Implement service discovery and load balancing for efficient orchestration
Q4. Explain the Kubernetes Architecture ?
Kubernetes Architecture is a container orchestration platform that manages the deployment, scaling, and operation of application containers.
Kubernetes follows a master-slave architecture with a master node and multiple worker nodes.
The master node controls the cluster and schedules workloads, while the worker nodes run the actual containers.
Key components of Kubernetes architecture include Pods, Nodes, Services, and Controllers.
Pods are the smallest deployable units in Kubern...read more
Q5. expalin kubernetes architecture
Kubernetes architecture is a container orchestration platform that manages containerized applications across a cluster of nodes.
Kubernetes follows a master-slave architecture with a master node and multiple worker nodes.
Master node components include API server, scheduler, controller manager, and etcd.
Worker node components include kubelet, kube-proxy, and container runtime (e.g. Docker).
Nodes communicate with each other through the API server.
Kubernetes uses labels and selec...read more
Q6. Architecture of k8s
Kubernetes (k8s) is an open-source container orchestration platform for automating deployment, scaling, and management of containerized applications.
Kubernetes follows a master-slave architecture with a master node and multiple worker nodes.
Master node components include API server, scheduler, controller manager, and etcd.
Worker node components include kubelet, kube-proxy, and container runtime (e.g. Docker).
Pods are the smallest deployable units in Kubernetes, consisting of ...read more
