KUBERNETES(1)(kubernetes)

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

okay so real talk, this is from the kubernetes manual, section 1. Eric Paris wrote the OG version back in Jan 2015 and honestly? iconic of him. let's get into it 🫶

✨ NAME ✨

kubeadm certs renew scheduler.conf — renews the certificate that's embedded in the kubeconfig file so the scheduler manager can use it 💅

---

🌸 SYNOPSIS 🌸

kubeadm certs renew scheduler.conf [OPTIONS]

---

🦋 DESCRIPTION 🦋

So basically, this command renews the certificate embedded in the kubeconfig file for the scheduler manager to use. that's the whole vibe. 🎀

Renewals run unconditionally, no cap — doesn't matter if your certificate's expiration date is tomorrow or in 2099, it just goes. And extra attributes like SANs? They're based on the existing file/certificates, so you do not need to resupply them. not me saving you a whole step bestie 😌

Renewal by default tries to use the certificate authority in the local PKI managed by kubeadm. as an alternative, you can use the K8s certificate API for certificate renewal, or — last option on the menu — generate a CSR request. options, options, options ✨

⚠️ After renewal, to make your changes actually effective, you gotta restart the control-plane components, and eventually re-distribute the renewed certificate if that file is used somewhere else. the renewal is giving "done" but the cluster is giving "not yet" 💀

---

💖 OPTIONS 💖

• --cert-dir="/etc/kubernetes/pki" — the path where you save the certificates 🗂️
• --config="" — path to a kubeadm configuration file.
• --kubeconfig="/etc/kubernetes/admin.conf" — the kubeconfig file to use when talking to the cluster. If the flag isn't set, a set of standard locations can be searched for an existing kubeconfig file. it'll go looking, fr fr 🔍

---

👑 OPTIONS INHERITED FROM PARENT COMMANDS 👑

• --rootfs="" — the path to the 'real' host root filesystem. This will cause kubeadm to chroot into the provided path. fancy, honestly 🧚
• --version=false — --version, --version=raw prints version information and quits; --version=vX.Y.Z... sets the reported version. tell me what version you are, periodt ⭐
