✨ KUBERNETES(1)(kubernetes) — the kubeadm edition ✨

okay bestie, sit down, hydrate, and let's talk about kubeadm upgrade apply phase kubelet-config 💅 this is one of those little hidden gems that lives under kubeadm upgrade apply phase, and it's giving very specific, very useful energy 🫶

---

🎀 NAME 🎀

kubeadm upgrade apply phase kubelet-config — lowkey just here to Upgrade the kubelet configuration for this node ✨

---

🌸 SYNOPSIS 🌸

kubeadm upgrade apply phase kubelet-config [OPTIONS]

---

🦋 DESCRIPTION 🦋

So what does it actually do, you ask? It upgrades the kubelet configuration for this node — and the way it gets that config is by downloading it from the kubelet-config ConfigMap that's chilling in your cluster ☁️ no cap, that's the whole vibe. Pull the config from the cluster, apply it to the node, move on with your day 💖

---

💅 OPTIONS 💅

• --config="" — path to a kubeadm configuration file. it's empty by default, so nothing's set unless you say so 🙈
• --dry-run=false — do not change any state, just print out what actions would be performed 👀 perfect for when you want the tea without the consequences. defaults to false.
• --kubeconfig="/etc/kubernetes/admin.conf" — the kubeconfig file to use when talking to the cluster 💬 if you don't set this flag, a set of standard locations gets searched for an existing kubeconfig file. so it'll go looking for one like a bestie looking for you in a crowd 🫶
• --patches="" — path to a directory that contains files named "target[suffix][+patchtype].extension" 🧚 for example, "kube-apiserver0+merge.yaml" or just "etcd.json". here's the breakdown, because this one has lore:
  • "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 these match the patch formats supported by kubectl. the default "patchtype" is "strategic" ✨
  • "extension" must be either "json" or "yaml" — no third option, periodt 📝
  • "suffix" is an optional string that can be used to determine which patches are applied first, alpha-numerically 🔤

---

🌈 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. it's giving commitment.
• --version=false — --version, --version=raw prints version information and quits; --version=vX.Y.Z... sets the reported version 🔢 so you can either ask the version or tell it what to be. main character energy fr fr.
