I building my cluster with nodes from different datacenters. Actually, the cluster has lived in one dc for some time with 5 node (1 server + 4 agents). Now I'm adding new node in different dc.
Using this tutorial as an example https://docs.k3s.io/networking/distributed-multicloud#embedded-k3s-multicloud-solution
For server:
For agent:
The problem is non of the agent's pod can resolve any hostname. I'm using official dns resolution guide https://kubernetes.io/docs/tasks/administer-cluster/dns-debugging-resolution/ and
nslookup
is failing both for internal and external requests.Internal:
External:
External with cloudflare's dns:
What could be the problem of this DNS issue? How could I resolve it?
P.S. I'm using k3s version
v1.30.4+k3s1
(latest at the time of writing) both for server and agents.Beta Was this translation helpful? Give feedback.
