A clear and concise description of what happend.

When creating a cluster with multiple nodes, it will panic probabilistically. In my environment, there are 3 master nodes and 3 worker nodes. It is found that kk panics when creating the cluster.

It seems that when there are many nodes, JoinNodesModulejoin will be executed concurrently, in which GenerateKubeadmConfig calls util.GetArgs, resulting in concurrent reading and writing of the map v1beta2.ApiServerArgs.

Relevant log output

Generate kubeadm config
fatal error: concurrent map writes
