Logging with kubectl logs
Access and analyze container logs directly from your Kubernetes cluster using kubectl.
Why Logs Matter in Kubernetes
In Kubernetes, understanding what your applications are doing is key. Logs are like your application's diary, recording events, errors, and status updates.
They are essential for:
- Debugging: Pinpointing issues when something goes wrong.
- Monitoring: Keeping an eye on application health and performance.
- Auditing: Tracking actions and changes over time.
Container Logs Explained
When a containerized application runs, it typically writes output to its standard output (stdout) and standard error (stderr) streams. Kubernetes collects these streams for each container.
These streams are then made available through the Kubernetes API, allowing you to easily access them without having to SSH into nodes or individual containers.
