πŸ’– KUBERNETES(1)(kubernetes) πŸ’–

okay bestie, welcome to the kubernetes manual, section 1, and literally this whole page is about one little command that does one little thing but it's SO important, trust. (also, fun fact, the original was compiled by Eric Paris back in Jan 2015, we'll get to that at the end, mwah πŸ’…)


✨ NAME ✨

kubeadm config print join-defaults β€” print out the default join configuration, like, the one you can actually use for 'kubeadm join'. it's giving scaffolding, it's giving template, it's giving "here's what your config would look like if you didn't touch anything" πŸŽ€


🌸 SYNOPSIS 🌸

kubeadm config print join-defaults [OPTIONS]

that's it. that's the whole vibe. no positional args, just the command and optionally some flags. slay πŸ¦‹


πŸ’« DESCRIPTION πŸ’«

so what does this actually do?? it prints objects β€” for example, the default join configuration β€” the exact same one that gets used for 'kubeadm join'. so if you've ever been like "wait what does kubeadm actually assume about my node before I hand it a config", this is how you find out. no cap. πŸ‘‘

⚠️ okay but listen, important part: sensitive values like the Bootstrap Token fields get swapped out for placeholder values like "abcdef.0123456789abcdef". why? so the thing still passes validation but does not do the real computation for actually creating a token. so don't go copy-pasting that token expecting it to work, bestie, it's literally fake on purpose πŸ˜­πŸ™ˆ

🫢 OPTIONS INHERITED FROM PARENT COMMANDS 🫢

these aren't even this command's own flags, they're inherited from the parent command, and yes they still totally apply:

  • --kubeconfig="/etc/kubernetes/admin.conf" β€” the kubeconfig file to use when talking to the cluster. if this flag isn't set, a set of standard locations gets searched for an existing kubeconfig file. so like, it'll go looking for you, she's resourceful πŸ’œ
  • --rootfs="" β€” the path to the 'real' host root filesystem. this makes kubeadm chroot into the path you provided. yes, chroot. as in, changing your whole root. iconic but also, be careful where you point this πŸ”₯
  • --version=false β€” version info, but make it fashion: --version or --version=raw prints version information and quits; --version=vX.Y.Z... sets the reported version. so you can peek at the version or literally lie about it, your call ✨

πŸ“œ HISTORY πŸ“œ

January 2015, originally compiled by Eric Paris (eparis at redhat dot com), based on the kubernetes source material β€” but honestly, hopefully they've been automatically generated ever since! the way that's a mood, fr fr 😭🌸


and that's the page!! Manuals, User section, KUBERNETES(1)(kubernetes) β€” that's the source, the section and the title, and the whole thing is dated back to January 2015. go print those join defaults, bestie, you got this πŸŽ€πŸ’…πŸ¦‹πŸ’œ
