我正在尝试使用 kubeadm 在 Azure 中创建一个 HA Kubernetes 集群如此处所述 https://kubernetes.io/docs/setup/independent/high-availability/
我只使用 1 个主节点时一切正常，但是当更改为 3 个主节点时，kube-dns 不断因 apiserver 问题而崩溃
运行时可以看到kubectl get nodes 3 个主节点已准备就绪

但是 dns 和仪表板 pods 不断崩溃

最佳答案
我终于明白了这一点。我没有将相同的服务帐户签名 key 复制到每个主节点( sa.key 、 sa.pub )。
这些 key 记录在此处:https://github.com/kubernetes/kubeadm/blob/master/docs/design/design_v1.7.mda private key for signing ServiceAccount Tokens (sa.key) along with its public key (sa.pub)
我错过的步骤记录在这里:https://kubernetes.io/docs/setup/independent/high-availability/Copy the contents of /etc/kubernetes/pki/ca.crt, /etc/kubernetes/pki/ca.key, /etc/kubernetes/pki/sa.key and /etc/kubernetes/pki/sa.pub and create these files manually on master1 and master2
