Logging¶

Logging is a way to monitor and troubleshoot the applications running in a Kubernetes cluster. It is important to have a logging strategy in place to monitor the health of the applications and to troubleshoot issues when they arise.

sample-pod.yaml

apiVersion: v1
kind: Pod
metadata:
  name: sample-pod
spec:
  containers:
    - name: web-app
      image: webapp
    - name: db:
      image: webapp-db

Bash

# View the live logs of a pod
kubectl logs -f <pod-name>
kubectl logs -f sample-pod

# View the container logs if there are multiple containers in a pod
kubectl logs -f <pod-name> -c <container-name>
kubectl logs -f sample-pod -c webapp-db
