OC-ADM-CORDON(1)

💅 oc adm cordon (OpenShift CLI User Manuals, section 1)

okay bestie, welcome to the oc adm cordon page — this is from the OpenShift CLI User Manuals, manual section 1, and it's genuinely such a vibe once you get it. let's go 🎀

---

✨ NAME ✨

oc adm cordon — mark a node as unschedulable 🚫

🦋 SYNOPSIS 🦋

oc adm cordon [OPTIONS]

🌸 DESCRIPTION 🌸

Mark node as unschedulable.

that's it. that's the whole thing. no cap, it's giving "short and iconic" 👑

💖 OPTIONS 💖

• --dry-run="none" — lowkey a vibe check before you commit 🙈. Has to be "none", "server", or "client". With the client strategy, it literally just prints the object that would be sent — nothing actually gets sent. With the server strategy, it submits a server-side request but does not persist the resource. so you see the tea without spilling it.
• -l, --selector="" — the label query filter, aka how you pick which cuties you're talking to 💅. Supports '=', '==', '!=', 'in', 'notin' (e.g. -l key1=value1,key2=value2,key3 in (value3)). Matching objects must satisfy all of the specified label constraints — every single one, no skipping, periodt.

👑 OPTIONS INHERITED FROM PARENT COMMANDS 👑

these are the hand-me-downs from the parent command, and honestly they ate 🍓

• --as="" — username to impersonate for the operation. User could be a regular user or a service account in a namespace. main character energy but borrowed 💀
• --as-group=[] — group to impersonate for the operation. this flag can be repeated to specify multiple groups — stack 'em like bracelets 🫶
• --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="/homeless-shelter/.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. ⚠️ this will make your HTTPS connections insecure — like, actually insecure, not "insecure" in a cute way. be so for real before you flip this one 😭
• --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 KUBECTL_KUBERC=false feature gate or turning off the feature KUBERC=off.
• --match-server-version=false — require server version to match client version. picky king behavior 👑
• -n, --namespace="" — if present, the namespace scope for this CLI request.
• --profile="none" — name of profile to capture. One of (none|cpu|heap|goroutine|threadcreate|block|mutex). collect the whole set, why not 🎀
• --profile-output="profile.pprof" — name of the file to write the profile to.
• --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 — infinite patience, the ultimate soft girl trait 🌸
• -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.
• --warnings-as-errors=false — treat warnings received from the server as errors and exit with a non-zero exit code. no notes taken, only ✨consequences✨

🌈 EXAMPLE 🌈

# Mark node "foo" as unschedulable
