KUBERNETES(1)(kubernetes)

💅 KUBERNETES(1)(kubernetes) 💅

okay bestie, welcome to the kubernetes manual page — yes, the whole thing, and yes I read all of it so you don't have to. fun fact: this page was originally written by Eric Paris back in Jan 2015, and it's still serving looks in the kubernetes man page family. let's get into it ✨

---

✨ NAME ✨

kubectl set selector — literally just: put a selector on a resource. that's the whole vibe. 🎀

---

✨ SYNOPSIS ✨

kubectl set selector [OPTIONS]

---

🦋 DESCRIPTION 🦋

Set the selector on a resource. heads up though: the new selector will overwrite the old selector if the resource already had one before you ran set selector. no takebacks, it's giving overwrite energy. 💀

A selector must begin with a letter or number, and may contain letters, numbers, hyphens, dots, and underscores, up to 63 characters. periodt.

If --resource-version is specified, then updates will use this resource version — otherwise the existing resource-version will be used. iykyk.

Note: currently selectors can only be set on Service objects. so like. only Services. that's the rule, bestie. 🙈

---

💖 OPTIONS 💖

• --all=false — select all resources in the namespace of the specified resource types. all of them. the whole group chat.
• --allow-missing-template-keys=true — if true, ignore any errors in templates when a field or map key is missing in the template. Only applies to golang and jsonpath output formats. very "don't worry about it" of it.
• --dry-run="none" — must be "none", "server", or "client". If client strategy, only print the object that would be sent, without sending it. If server strategy, submit server-side request without persisting the resource. it's a rehearsal, not the real show ✨
• --field-manager="kubectl-set" — name of the manager used to track field ownership. that's who owns this field, and it's kubectl-set.
• -f, --filename=[] — identifying the resource. point at the thing, bestie.
• --local=false — if true, annotation will NOT contact api-server but run locally. no network, just vibes, offline mode 💅
• -o, --output="" — output format. One of: (json, yaml, kyaml, name, go-template, go-template-file, template, templatefile, jsonpath, jsonpath-as-json, jsonpath-file). pick your aesthetic.
• --record=false — record current kubectl command in the resource annotation. If set to false, do not record the command. If set to true, record the command. If not set, default to updating the existing annotation value only if one already exists. it's the receipts, lowkey.
• -R, --recursive=true — process the directory used in -f, --filename recursively. Useful when you want to manage related manifests organized within the same directory. go deep, girl 🌀
• --resource-version="" — if non-empty, the selectors update will only succeed if this is the current resource-version for the object. Only valid when specifying a single resource. optimistic concurrency but make it fashion.
• --show-managed-fields=false — if true, keep the managedFields when printing objects in JSON or YAML format.
• --template="" — template string or path to template file to use when -o=go-template, -o=go-template-file. The template format is golang templates [http://golang.org/pkg/text/template/#pkg-overview]. go forth and template, icon.

🌈 OPTIONS INHERITED FROM PARENT COMMANDS 🌈

these are the family options, they come from the parent command and they're all so valid:

• --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.
• --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. This will make your HTTPS connections insecure. like, genuinely. don't be sloppy with this one bestie 😭
• --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. no mismatched fits allowed.
• -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. zero = infinite patience, we love a calm queen 🧘
• -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. no warnings tolerated, we're strict now 💅

🎀 EXAMPLE 🎀

look at this pipeline, it's so clean it ate:

# Set the labels and selector before creating a deployment/service pair
kubectl create service clusterip my-svc --clusterip="None" -o yaml --dry-run=client | kubectl set selector --local -f - 'environment=qa' -o yaml | kubectl create -f -
kubectl create deployment my-dep --image=nginx -o yaml --dry-run=client | kubectl label --local -f - environment=qa -o yaml | kubectl create -f -

📜 HISTORY 📜

January 2015, originally compiled by Eric Paris (eparis at redhat dot com) based on the kubernetes source material, but hopefully they have been automatically generated since! slay, automation. 🦋

okay that's the whole page, you're officially educated bestie 💖 from the Manuals / User section of the KUBERNETES(1)(kubernetes) family — original dated Jan 2015, still iconic. now go set a selector (on a Service, obviously). mwah 🫶✨
