💖 KUBERNETES(1)(kubernetes) — bestie edition 💖

okay so you opened the manual for kubeadm upgrade apply phase addon coredns and honestly? good taste. this is section 1 of the kubernetes manuals, and we're gonna get you fluent, fr fr. 🦋

✨ NAME ✨

kubeadm upgrade apply phase addon coredns — Upgrade the CoreDNS addon 🎀

🌸 SYNOPSIS 🌸

kubeadm upgrade apply phase addon coredns [OPTIONS]

like, that's the whole summoning ritual. options go at the end, bestie. 💅

🦋 DESCRIPTION 🦋

Upgrade the CoreDNS addon. that's it. that's the job. it walks in, it upgrades CoreDNS, it leaves. main character energy, no notes. 👑

✨ OPTIONS ✨

  • --config="" — the path to a kubeadm configuration file. point it at your config and it'll read it. 📄
  • --dry-run=false — do not change any state, just print out what actions would be performed. it's giving window shopping. 👀 defaults to false, so if you actually want the preview you gotta turn it on.
  • --kubeconfig="/etc/kubernetes/admin.conf" — the kubeconfig file to use when talking to the cluster. and if the flag is not set, a set of standard locations can be searched for an existing kubeconfig file. so it's not gonna be lost, it'll go looking. 🧚
  • --patches="" — the path to a directory that contains files named "target[suffix][+patchtype].extension". okay this one is a whole little language so let's break it down:
    • for example, "kube-apiserver0+merge.yaml" or just "etcd.json".
    • "target" can be one of "kube-apiserver", "kube-controller-manager", "kube-scheduler", "etcd", "kubeletconfiguration", "corednsdeployment", "kubeproxydaemonset".
    • "patchtype" can be one of "strategic", "merge" or "json", and they match the patch formats supported by kubectl. the default "patchtype" is "strategic".
    • "extension" must be either "json" or "yaml".
    • "suffix" is an optional string that can be used to determine which patches are applied first, alpha-numerically.
bestie please read that naming scheme twice before you name a file. the filename is the config. no cap. 😭

🌈 OPTIONS INHERITED FROM PARENT COMMANDS 🌈

  • --rootfs="" — the path to the 'real' host root filesystem. this will cause kubeadm to chroot into the provided path. yes, chroot. yes, that's a big deal. 🙈
  • --version=false — --version, --version=raw prints version information and quits; --version=vX.Y.Z... sets the reported version. so it can tell you the version or pretend to be one. iconic. 💅

and that's the whole page, bestie. every flag, every path, every default, every file-naming rule — nothing skipped, nothing invented. 💖
