The command stern ${pod_query} --since ${15m} is used to tail and display logs from Kubernetes pods that match a certain query, with logs starting from the last 15 minutes.

Here's what each part of the command does:

• stern: This is the name of the command-line tool being used. Stern is a tool developed for tailing multiple Kubernetes pods and containers at once, making it easier to track logs.
• ${pod_query}: This is a placeholder that represents the query used to filter which pods' logs should be displayed. The actual value of the variable will depend on the specific use case. For example, it could be the name of a single pod ('app-1') or a label selector ('app=myapp').
• --since ${15m}: This flag specifies a time duration to limit the logs displayed. In this case, it is set to the last 15 minutes (15m). The command will only show logs from the pods that have been generated within the past 15 minutes. Logs that are older than 15 minutes will not be displayed.

By running this command, you'll be able to monitor and view logs from Kubernetes pods that match a certain query, with logs starting from the last 15 minutes.
