При запуске cert-manager я получаю следующее сообщение
TLS handshake error from 10.42.152.128:38676: EOF

Интересно, что нет стручка с этим IP
$ kubectl get pod -o wide --all-namespaces | grep 128

Аналогичная ошибка на cert-manager pod

У меня есть два ClusterIssuer
kubectl get ClusterIssuer --namespace cert-manager
NAME READY AGE
letsencrypt-prd True 42d
letsencrypt-stg True 42d
Но сертификата пока нет:
kubectl get certificate --all-namespaces
No resources found
Когда я пытаюсь запросить сертификат, я получаю ту же ошибку
kubectl apply -f mycert.yml
Error from server (InternalError): error when creating "cert-wyssmann-dev.yml": Internal error occurred: failed calling webhook "webhook.cert-manager.io": Post https://cert-manager-webhook.cert-manager.svc:443/mutate?timeout=30s: net/http: TLS handshake timeout
Я не уверен, как именно я могу добраться до сути проблемы. Я запустил sonobouy, чтобы посмотреть, поможет ли это мне, однако тест не прошел на 2 из 3 моих узлов.
