[已解决] 法兰绒不适用于我更改为编织网的那个。如果您不想在 config.yaml 中提供 pod-network-cidr："10.244.0.0/16"标志
我想使用 kubernetes 进行多主设置，并尝试了很多不同的方法。即使是我采取的最后一种方法也不起作用。问题是dns和法兰绒网络插件不想启动。他们每次都会获得CrashLoopBackOff状态。下面列出了我的做法。
首先在每个节点上使用此命令创建一个外部 etcd 集群(仅更改了地址(
nohup etcd --name kube1 --initial-advertise-peer-urls http://192.168.100.110:2380
--listen-peer-urls http://192.168.100.110:2380
--listen-client-urls http://192.168.100.110:2379,http://127.0.0.1:2379
--advertise-client-urls http://192.168.100.110:2379
--initial-cluster-token etcd-cluster-1
--initial-cluster kube1=http://192.168.100.110:2380,kube2=http://192.168.100.108:2380,kube3=http://192.168.100.104:2380
--initial-cluster-state new &
然后我为 kubeadm init 命令创建了一个 config.yaml 文件。
apiVersion: kubeadm.k8s.io/v1alpha1
kind: MasterConfiguration
api:
advertiseAddress: 192.168.100.110
etcd:
endpoints:
- "http://192.168.100.110:2379"
- "http://192.168.100.108:2379"
- "http://192.168.100.104:2379"
apiServerExtraArgs:
apiserver-count: "3"
apiServerCertSANs:
- "192.168.100.110"
- "192.168.100.108"
- "192.168.100.104"
- "127.0.0.1"
token: "64bhyh.1vjuhruuayzgtykv"
tokenTTL: "0"
Start command： kubeadm init --config/root/config.yaml
所以现在复制其他节点上的/etc/kubernetes/pki 和配置，并以相同的方式启动其他主节点。但它不起作用。
那么初始化多主 kubernetes 集群的正确方法是什么，或者为什么我的法兰绒网络无法启动？

如果您没有任何托管首选项，并且可以 AWS 上创建集群，那么使用 KOPS 可以非常轻松地完成。
https://github.com/kubernetes/kops
通过 KOPS，您可以轻松为主节点配置自动缩放组，并可以指定集群所需的主节点和节点数。
法兰绒不起作用，所以我改用编织网。如果您不想使用 在 config.yaml 中提供 pod-network-cidr："10.244.0.0/16"标志
