Status of different K8s components

kubectl get nodes | pod | service | replicaset | deployment | all kubectl get pod -o wide More columns with info kubectl get deployment [name] -o yaml current in yaml format (useful for debugging)

Debugging pods

kuberctl logs [pod name] kubectl logs nginx-depl-{pod-name}

kubectl exec -it [pod name] -- bin/bash kuberctl describe pod [pod name] kuberctl describe pod nginx-depl-{pod name}

Configuration file Deployment & Service

Each configuration file has 3 parts

1. metadata
2. specification
3. status (automatic generated)
   • desired state
   • Actual state
     • Both have to match. If not K8s knows something has to be fixed
     • status is updated continues
     • etcd is providing the info for status
