✨ KUBERNETES(1)(kubernetes) ✨

okay bestie, welcome to the kubectl cordon page from the kubernetes manual 💖 this is section 1 of the kubernetes manuals, and yes it's giving "I read manpages for fun" energy. no shame. 🎀

Eric Paris wrote the original back in Jan 2015, and we're gonna get through the whole thing together. grab a boba. 🧋

🌸 NAME 🌸

kubectl cordon — mark node as unschedulable

literally that's it. that's the whole job. 💅

---

🦋 SYNOPSIS 🦋

kubectl cordon [OPTIONS]

---

✨ DESCRIPTION ✨

Mark node as unschedulable.

fr fr that's the description. short, sweet, no notes. 👑

---

💅 OPTIONS 💅

• --dry-run="none" — Must be "none", "server", or "client". If it's the client strategy, it only prints the object that would have been sent, without actually sending it. If it's the server strategy, it submits a server-side request without persisting the resource. (yes, the default is "none", so nothing dry happens unless you ask)
• -l, --selector="" — Selector (label query) to filter on, and it supports '=', '==', '!=', 'in', 'notin'. (e.g. -l key1=value1,key2=value2,key3 in (value3)). Every matching object has to satisfy all of the specified label constraints — no picking and choosing, bestie. 🙈

---

🌈 OPTIONS INHERITED FROM PARENT COMMANDS 🌈

these come from the parent command, so they're not cordon's own, but they ride along and they all matter. do not skip. 💖

• --as="" — Username to impersonate for the operation. The user could be a regular user or a service account in a namespace.
• --as-group=[] — Group to impersonate for the operation. This flag can be repeated to specify multiple groups.
• --as-uid="" — UID to impersonate for the operation.
• --as-user-extra=[] — User extras to impersonate for the operation. This flag can be repeated to specify multiple values for the same key.
• --cache-dir="/home/username/.kube/cache" — Default cache directory
• --certificate-authority="" — Path to a cert file for the certificate authority
• --client-certificate="" — Path to a client certificate file for TLS
• --client-key="" — Path to a client key file for TLS
• --cluster="" — The name of the kubeconfig cluster to use
• --context="" — The name of the kubeconfig context to use
• --disable-compression=false — If true, opt-out of response compression for all requests to the server
• --insecure-skip-tls-verify=false — If true, the server's certificate will not be checked for validity.

🚨 bestie listen. This will make your HTTPS connections insecure. That's not a vibe, that's a warning. insecure. 😭

• --kubeconfig="" — Path to the kubeconfig file to use for CLI requests.
• --kuberc="" — Path to the kuberc file to use for preferences. This can be disabled by exporting the KUBECTL_KUBERC=false feature gate or turning off the feature KUBERC=off.
• --match-server-version=false — Require server version to match client version
• -n, --namespace="" — If present, the namespace scope for this CLI request
• --password="" — Password for basic authentication to the API server
• --profile="none" — Name of profile to capture. One of (none|cpu|heap|goroutine|threadcreate|block|mutex|trace)
• --profile-output="profile.pprof" — Name of the file to write the profile to
• --proxy-url="" — Proxy URL to use for requests to the API server
• --request-timeout="0" — The length of time to wait before giving up on a single server request. Non-zero values should contain a corresponding time unit (e.g. 1s, 2m, 3h). A value of zero means don't timeout requests.
• -s, --server="" — The address and port of the Kubernetes API server
• --tls-server-name="" — Server name to use for server certificate validation. If it is not provided, the hostname used to contact the server is used
• --token="" — Bearer token for authentication to the API server
• --user="" — The name of the kubeconfig user to use
• --username="" — Username for basic authentication to the API server
• --version=false — --version, --version=raw prints version information and quits; --version=vX.Y.Z... sets the reported version
• --warnings-as-errors=false — Treat warnings received from the server as errors and exit with a non-zero exit code

🎀 EXAMPLE 🎀
