Bootstrap Token

[rmb938]

Hey, I just read part of your blog post "Letter to Santa Kube" and saw your complaint about the kubeadm bootstrap token.

You can easily list all kubeadm tokens by running kubeadm token list.

Or even better you can generate the token ahead of time before initializing by using kubeadm token generate then passing that to init via kubeadm init --token ${token_here}

Hi! Thanks a lot for the feedback. Unfortunately, kubeadm token list gives a formatted output; so to retrieve the token I have to add a bit of processing (e.g. with grep or awk or similar commands). It's not a big deal but I don't like to parse "human-readable" output, because it might change from one version to another. That's why I like the docker swarm join-token -q command: it will output the token, just the token, without anything else.

However, you're totally right, kubeadm token generate looks like it's waaaay simpler than my current hack :-)

Thank you for the suggestion, I'll implement it!
