Cilium Cluster Mesh at Azure

Question

I need your help to create multi-cluster networking.

What i have done:

1- kubectl apply -f chaining.yaml

2-

`helm template cilium \
  --namespace cilium \
  --set nodeinit.azure=true \
  --set global.cni.chainingMode=generic-veth \
  --set global.cni.customConf=true \
  --set global.nodeinit.enabled=true \
  --set global.cni.configMap=cni-configuration \
  --set global.tunnel=disabled \
  --set global.etcd.enabled=true \
  --set global.etcd.managed=true \
  > cilium.yaml
kubectl create -f cilium.yaml`

3- kubectl -n kube-system edit cm cilium-config

4- apiVersion: v1 kind: Service metadata: name: cilium-etcd-external namespace: kube-system annotations: service.beta.kubernetes.io/azure-load-balancer-internal: "true" spec: type: LoadBalancer ports: - port: 2379 selector: app: etcd etcd_cluster: cilium-etcd io.cilium/app: etcd-operator

5-

git clone https://github.com/cilium/clustermesh-tools.git cd clustermesh-tools

./extract-etcd-secrets.sh

./generate-secret-yaml.sh > clustermesh.yaml

6-

./generate-name-mapping.sh > ds.patch kubectl -n kube-system patch ds cilium -p "$(cat ds.patch)"

7-

kubectl apply -f clustermesh.yaml

kubectl -n kube-system delete pod -l k8s-app=cilium

Result:

Clusters can not see each other. Dou you have any idea?

Answer 1

To test that clusters do not see each other, are you running "cilium node list" and only seeing nodes form one of the clusters?

Have you followed all steps on the clustermesh troubleshooting guide? https://docs.cilium.io/en/v1.6/gettingstarted/clustermesh/#troubleshooting

If that doesn't help, I would recommend hopping on Cilium Slack (https://cilium.io/slack), chatting with developers/community members, and potentially providing a sysdump (https://docs.cilium.io/en/v1.6/troubleshooting/#automatic-diagnosis).
