ElasticSearch failed to set up in k8s with calico vpp #674

Closed guoshuxu closed 10 months ago

Environment

Calico/VPP version: v3.26.0
Kubernetes version: v1.28.3
Deployment type: bare-metal
Network configuration: Calico VPP w/VXLAN enabled

Issue description ElasticSearch fails: Check the log:

It seems that in elasticsearch pod, it can not resolve the public address. Is this caused by VPP route table? Compared with Calico CNI(w/o VPP), there is no such issue.

Is it a kind cluster by any chance?

guoshuxu commented 10 months ago

It is a k8s cluster on bare-metal created by Kubespray.

onong commented 10 months ago

We have not tested any with kubespray.

Does DNS resolution fail from the other pods too? That is, launch a pod in the cluster and check if DNS works?

guoshuxu commented 10 months ago

Found the dns problem and close it. Thanks @onong.
