Quando eu acesso o mesmo domínio nos mesmos kuberetes, os v2.10.1dns do traefik pod são diferentes dos outros, este é o dns do traefik:
/ $ nslookup kubernetes.default
Server: 100.100.2.136
Address: 100.100.2.136:53
** server can't find kubernetes.default: NXDOMAIN
** server can't find kubernetes.default: NXDOMAIN
e este é o outro pod DNS parecido com:
root@y-websocket-service-9654986bc-cf65m:/home/node/app# nslookup kubernetes.default
Server: 10.96.0.10
Address: 10.96.0.10#53
Name: kubernetes.default.svc.cluster.local
Address: 10.96.0.1
esta é a definição do traefik no kubernetes v1.29.x, semelhante a:
