Kubernetes Time Check Pod - Task failed error

Hey,

I have successfully completed this task.
However, it argues my mount path is incorrect, despite it is exactly configured as the instructions.

Here is the configuration of the pod:

Please post YAML in

code blocks

as all the formatting is broken when you paste as plain text and we cannot validate it.

type ``` on a line by itself, paste the YAML, and type that again below the YAML to code block it.

I just did that lab and it works for me. Remember that each time you retry the lab, it may state different values for namespace, pod name, config map name, value of TIME_FREQ, mount path for the log-volume, so you cannot save the manifest you created for a previous attempt and paste it back in next time without carefully editing it first.
