[K8S] kubectl을 이용하여 정보 출력할 때 다양한 조건으로 정렬(소트)하기

Pod 이름으로 정렬

kubectl get pods --sort-by=.metadata.name

예)

$ kubectl get pods --sort-by=.metadata.name --all-namespaces

NAMESPACE     NAME                                      READY   STATUS      RESTARTS   AGE

kube-system   helm-install-traefik-4jcxl                0/1     Completed   1          51m

kube-system   helm-install-traefik-crd-5qhs7            0/1     Completed   0          51m

kube-system   local-path-provisioner-7b7dc8d6f5-zz2wd   1/1     Running     0          51m

kube-system   metrics-server-668d979685-psbjq           1/1     Running     0          51m

kube-system   svclb-traefik-qlrmv                       2/2     Running     0          51m

kube-system   traefik-7cd4fcff68-l92c4                  1/1     Running     0          51m

만들어진 timestamp로 정렬

kubectl get pods --sort-by=.metadata.creationTimestamp

예)

$ kubectl get pods --sort-by=.metadata.creationTimestamp --all-namespaces

NAMESPACE     NAME                                      READY   STATUS      RESTARTS   AGE

kube-system   helm-install-traefik-4jcxl                0/1     Completed   1          52m

kube-system   metrics-server-668d979685-psbjq           1/1     Running     0          52m

kube-system   svclb-traefik-qlrmv                       2/2     Running     0          52m

kube-system   traefik-7cd4fcff68-l92c4                  1/1     Running     0          52m

CPU 사용률 가장 높은 순으로 Pod 이름 출력

kubectl top pod --all-namespaces --sort-by=cpu

쿠버네티스 이벤트를 시간 순으로 출력

kubectl get events -A --sort-by=.metadata.creationTimestamp
