Use the following command to save logs for each pod into separate `.log` files

For Powershell (Windows)

kubectl get pods -n <namespace> --no-headers -o custom-columns=":metadata.name" | % { kubectl logs $_ -n {namespace} > "$_.log" }

Example : kubectl get pods -n bold-services --no-headers -o custom-columns=“:metadata.name” | % { kubectl logs $_ -n bold-services > “$_.log” }

For Linux

kubectl get pods -n <namespace> --no-headers -o custom-columns=":metadata.name" | while read pod; do kubectl logs "$pod" -n {namespace} > "$pod.log"; done

Example: kubectl get pods -n bold-services --no-headers -o custom-columns=“:metadata.name” | while read pod; do kubectl logs “$pod” -n bold-services > “$pod.log”; done
