I would like to list pods created within 24 hours. I didn't find any kubectl commands or anything to get those. Could anyone please help me with the kubectl command to get only the pods created in last 24 hours.
Not the most beautiful solution but this should work (or give you an idea if you want to further improve the command)
kubectl get pods -o go-template --template '{{range .items}}{{.metadata.name}} {{.metadata.creationTimestamp}}{{"\n"}}{{end}}' | awk '$2 > "'$(date -d 'yesterday' -Ins --utc | sed 's/+0000/Z/')'" { print $1 }'
List all pods names and filter rows with startTime > of one day.
In order to list all Pods created within the last 24h you can use the below command:
kubectl get pods --sort-by=.metadata.creationTimestamp | awk 'match($5,/^[0-9]h|^[0-9][0-9]h|^[0-9]m|^[0-9][0-9]m|^[0-9]s|^[0-9][0-9]s/) {print $0}'
If you also want to get Pods with errors only than you can use:
kubectl get pods --sort-by=.metadata.creationTimestamp | awk 'match($5,/^[0-9]h|^[0-9][0-9]h|^[0-9]m|^[0-9][0-9]m|^[0-9]s|^[0-9][0-9]s/) {print $0}' | grep -i Error
Or alternatively to only list Pods with the Pending
status:
kubectl get pods --field-selector=status.phase=Pending --sort-by=.metadata.creationTimestamp | awk 'match($5,/^[0-9]h|^[0-9][0-9]h|^[0-9]m|^[0-9][0-9]m|^[0-9]s|^[0-9][0-9]s/) {print $0}'
