I use the following command to create cluster token :
kubeadm token create --ttl=0This will show the following output:
W0504 18:31:48.031557 20703 configset.go:348] WARNING: kubeadm cannot validate component configs for API groups kubelet.config.k8s.io kubeproxy.config.k8s.io
Now after using kubeadm token list commnad, I want to copy the token to a file.
How to do so ?
The output of the token list can be formatted with jsonpath:
kubeadm token list -o=jsonpath='{.token}{"\n"}' > tokens.txtBy using this format only the token is printed by the list command.
