This is caused by KIND Issue #2326.
Recently we enabled the IPVS
proxy routing feature for the Kubernetes Test Network, in part to expose additional options for load balancing a set of gateway peers behind a shared service / DNS alias. Unfortunately this tickled a bug in the way KIND proxies DNS lookups through the Docker network, causing external lookups to fail.
Fix this issue by :
- revert IPVS -> IPTABLES routing when bootstrapping the KIND cluster.
- Update the Fabric Deployment Guide with additional instructions for IPVS Service Routing.
- Document the
route_localnet=1
workaround, for KIND environments validating IPVS:
# Workaround https://github.com/kubernetes-sigs/kind/issues/2326
for node in $(kind get nodes); do
docker exec "$node" sysctl net.ipv4.conf.all.route_localnet=1
done
I've confirmed the above workaround re-enables DNS.
