CKAD Question #16: Real Exam Question with Answer & Explanation

Question

Given a container that writes a log file in format A and a container that converts log files from format A to format B, create a deployment that runs both containers such that the log files from the first container are converted by the second container, emitting logs in format B. Task: • Create a deployment named deployment-xyz in the default namespace, that: • Includes a primary lfccncf/busybox:1 container, named logger-dev • Includes a sidecar lfccncf/fluentd:v0.12 container, named adapter-zen • Mounts a shared volume /tmp/log on both containers, which does not persist when the pod is deleted • Instructs the logger-dev container to run the command ``` while true; do echo "i luv cncf" >> /tmp/log/input.log; sleep 10; done ``` which should output logs to /tmp/log/input.log in plain text format, with example values: ``` i luv cncf i luv cncf i luv cncf ``` • The adapter-zen sidecar container should read /tmp/log/input.log and output the data to /tmp/log/output.* in Fluentd JSON format. Note that no knowledge of Fluentd is required to complete this task: all you will need to create this is to create the ConfigMap from the spec file provided at /opt/KDMC00102/fluentd-configma p.yaml , and mount that ConfigMap to /fluentd/etc in the adapter-zen sidecar container
