How can I get events messages from a pod, like this command using client-go Kubernetes API:
kubectl describe pod spark-t2f59 -n spark
Events:
Type Reason Age From Message
---- ------ ---- ---- -------
Warning FailedScheduling 104s default-scheduler 0/19 nodes are available: 15 Insufficient cpu, 19 Insufficient memory.
Warning FailedScheduling 104s default-scheduler 0/19 nodes are available: 15 Insufficient cpu, 19 Insufficient memory.
Warning FailedScheduling 45s default-scheduler 0/20 nodes are available: 16 Insufficient cpu, 20 Insufficient memory.
Warning FailedScheduling 34s default-scheduler 0/20 nodes are available: 16 Insufficient cpu, 20 Insufficient memory.
Normal NotTriggerScaleUp 97s cluster-autoscaler pod didn't trigger scale-up (it wouldn't fit if a new node is added): 1 Insufficient memory, 1 max node group size reachedIs there a way to get the same output of events but using client-go instead of kubectl??
Since you know the namespace and the pod name, you can do:
package main
import (
"context"
"fmt"
metav1 "k8s.io/apimachinery/pkg/apis/meta/v1"
"k8s.io/client-go/kubernetes"
"k8s.io/client-go/rest"
)
func main() {
config, _ := rest.InClusterConfig()
clientset, _ := kubernetes.NewForConfig(config)
events, _ := clientset.CoreV1().Events("spark").List(context.TODO(),metav1.ListOptions{FieldSelector: "involvedObject.name=spark-t2f59", TypeMeta: metav1.TypeMeta{Kind: "Pod"}})
for _, item := range events.Items {
fmt.Println(item)
}
}
