Actual exam question for Linux Foundation's CKAD exam
Question #: 33
Topic #: 2
[All CKAD Questions]

Refer to Exhibit.

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 Ifccncf/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

which should output logs to /tmp/log/input.log in plain text format, with example values:

* 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 achieve 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

Why not just use a single container? This seems complicated.

Wait, does Fluentd really need a ConfigMap? Seems like extra work.

Looks like we need to set up a shared volume for the logs.

Okay, let me think this through. I need to make sure the two containers are communicating correctly through the shared volume. The tricky part will be getting the Fluentd sidecar to transform the logs properly.

This is a good test of my Kubernetes knowledge. I'm confident I can get the deployment created, but the logging part might take me a bit of time to figure out.

No problem, I've done similar tasks before. I'll start by creating the deployment with the two containers and the shared volume, then focus on getting the logging setup right.

Hmm, I'm a bit confused about the Fluentd configuration. I'll need to review the provided ConfigMap to understand how to set that up properly.

Okay, I've got this! The customer is looking for community-built Salesforce.org solutions, so the obvious choices are the Power of Us Hub Group options - CumulusCI (CCI) and Open Source Commons & Community Sprints. Those seem like the most relevant resources to point the customer towards.
