Which commands can you use to access logs from Init containers and check the status values for an Init container when debugging Init containers that have failed repeatedly?
Understand the Problem
The question is asking which commands can be utilized to access logs and check status values for Init containers that have failed, specifically in a Kubernetes context. It seeks to identify the correct commands for debugging these containers.
Answer
Use 'kubectl logs' to access logs and 'kubectl describe pod' to check status.
You can use 'kubectl logs <pod_name> -c <init_container_name>' to access logs from Init containers. To check the status, use 'kubectl describe pod <pod_name>' to view details under Init Containers.
Answer for screen readers
You can use 'kubectl logs <pod_name> -c <init_container_name>' to access logs from Init containers. To check the status, use 'kubectl describe pod <pod_name>' to view details under Init Containers.
More Information
When debugging Init containers, it is critical to access their logs and status. 'kubectl logs' allows you to fetch logs, while 'kubectl describe pod' provides a comprehensive view of the pod, including Init container status.
Tips
A common mistake is not specifying the correct container name with the '-c' option when using 'kubectl logs', which might result in accessing logs for the wrong container or no logs at all.
