--insecure-skip-tls-verify doesn't work with kubefed join

[mmeliani]

I'm trying to add a clusters to federation using kubefed join :
this is the federation kube config file :

apiVersion: v1
clusters:
- cluster:
    certificate-authority-data: REDACTED
    server: https://k8s-apiserver.cluster.local:8443
  name: kubernetes
- cluster:
    certificate-authority-data: REDACTED
    server: https://172.16.1.4:32471
  name: federation
- cluster:
    insecure-skip-tls-verify: true
    server: https://139.54.130.49:32046
  name: kubernetes-s1
contexts:
- context:
    cluster: kubernetes
    namespace: default
    user: kubectl
  name: default-context
- context:
    cluster: federation
    user: federation
  name: federation
- context:
    cluster: kubernetes
    namespace: kube-system
    user: kubectl
  name: kube-system-context
- context:
    cluster: kubernetes-s1
    namespace: default
    user: kubernetes-admins1
  name: kubernetes-admin-s1
current-context: federation
kind: Config
preferences: {}
users:
- name: federation
  user:
    client-certificate-data: REDACTED
    client-key-data: REDACTED
    token: e7506989-42eb-11e8-bf70-fa163eb593a3
- name: federation-basic-auth
  user:
    password: e7506937-42eb-11e8-bf70-fa163eb593a3
    username: admin
- name: kubectl
  user:
    client-certificate-data: REDACTED
    client-key-data: REDACTED
- name: kubernetes-admins1
  user:
    token: eyJhbGciOiJSUz............

i run this command : kubefed join site-1 --host-cluster-context=default-context --cluster-context=kubernetes-admin-s1 --insecure-skip-tls-verify=true, the cluster is created but with offline status , is not reacheable ;
I'm using token bearer to reach the api server of the target cluster;
where am I going wrong ?
