Host günlüklerini görüntülemek

"oc get nodes" komutu hostların listesini döndürecektir.

# oc get nodes
NAME                                  STATUS   ROLES                  AGE    VERSION

Daha sonra hostların günlüklerini görüntülemek için "oc adm node-logs" komutu kullanılabilir. Ana hostlarıdaki mevcut günlüklerin listesini almak için önce bu komutu kullanmalısınız.

oc adm node-logs --role master --path=/

Örneğin, tüm ana hostlardan gelen tüm kubelet günlüklerini görüntülemek için.

oc adm node-logs --role master --unit kubelet

Bu üsteki sorgu genellikle stdout'un tüm bir günlüğünü uzun bir şekilde döndürecektir, bu nedenle her zaman ekrana gelen çıktıyı sınırladırmak için --tail eklemek isteyeceksiniz.

oc adm node-logs --role master --unit kubelet --tail=50

Sonuda birde grep ekleyip istediğiniz kelimeyi eklerseniz log araştırmada sizlere faydası olacaktır.

oc adm node-logs --role worker --unit kubelet --tail 50 --grep 'certificate has expired'
