Persistent Systems Devops Engineer Interview Questions and Answers

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

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

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

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

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
