无法在Argo CD中添加额外的kind集群

本地运行两个Kind集群，分别为dev-cluster和kind，Argo CD部署在dev-cluster上。执行argocd cluster add kind-kind --name stage命令将kind集群添加到Argo CD时，出现连接拒绝错误。

初始命令执行错误信息 #

WARNING: This will create a service account `argocd-manager` on the cluster referenced by context `kind-kind` with full cluster level privileges. Do you want to continue [y/N]? y
INFO[0005] ServiceAccount "argocd-manager" already exists in namespace "kube-system" 
INFO[0005] ClusterRole "argocd-manager-role" updated    
INFO[0005] ClusterRoleBinding "argocd-manager-role-binding" updated 
FATA[0005] rpc error: code = Unknown desc = Get "https://127.0.0.1:45249/version?timeout=32s": dial tcp 127.0.0.1:45249: connect: connection refused

当前kubectl上下文配置 #

执行kubectl config get-contexts输出：

CURRENT   NAME               CLUSTER            AUTHINFO           NAMESPACE
*         kind-dev-cluster   kind-dev-cluster   kind-dev-cluster   
          kind-kind          kind-kind          kind-kind          

已尝试的解决方法及结果 #

• 端口转发方案：
  执行端口转发命令：

kubectl port-forward kube-apiserver-kind-control-plane -n kube-system --context kind-kind 45249:45249

再次执行argocd cluster add命令，问题未解决，仍报连接拒绝。

• 节点IP直连方案：
  先获取kind集群节点的内部IP：

kubectl get nodes -o wide --context kind-kind

输出：

NAME                 STATUS   ROLES           AGE   VERSION   INTERNAL-IP   EXTERNAL-IP   OS-IMAGE             KERNEL-VERSION      CONTAINER-RUNTIME
kind-control-plane   Ready    control-plane   42d   v1.25.0   172.18.0.3    <none>        Ubuntu 22.04.1 LTS   5.15.0-52-generic   containerd://1.6.7

使用节点IP执行添加命令：

argocd cluster add kind-kind --name stage --server 172.18.0.3:45249

错误信息：

WARNING: This will create a service account `argocd-manager` on the cluster referenced by context `kind-kind` with full cluster level privileges. Do you want to continue [y/N]? y
INFO[0001] ServiceAccount "argocd-manager" already exists in namespace "kube-system" 
INFO[0001] ClusterRole "argocd-manager-role" updated

FATA[0001] Failed to establish connection to 172.18.0.3:45249: dial tcp 172.18.0.3:45249: connect: connection refused 

上述两种方法均未解决问题，依然出现连接拒绝错误。
