Question 95

What is a capability of node-level logging in Kubernetes?

Using the Kubernetes JSON logging driver enables log persistence

Output that is written to stdin is retrieved by using kubectl

Output that is written to stderr is not logged or retrievable by using kubectl

Using the local logging driver of Docker enables log persistence

Correct Answer: D

Using the local logging driver of Docker enables log persistence. Containers managed by Kubernetes leverage Docker for working with containers, including logging strategies. By using Docker's local logging driver, logs can be persisted on the node, which means they can survive container restarts and are available for analysis. This aligns with Kubernetes' node-level logging capabilities where logs are collected from nodes.

Discussion

pdobrinskiyOption: A

Kubernetes Node-Level Logging • Kubernetes Logging Architecture: Kubernetes relies on logging agents (often deployed as DaemonSets) to capture logs from nodes and containers. • JSON Logging Driver: Using a structured logging driver like JSON can help in standardizing log formats and facilitating easier log management and querying. Could be: A

psyborgOption: B

The question asks which of the choices is a capability of Kubernetes. B is a true statement and is related to Kubernetes. I think A and C are false, and D sounds like a capability of Docker.
