kubectl set resources

Synopsis

Specify compute resource requirements (CPU, memory) for any resource that defines a pod template. If a pod is successfully scheduled, it is guaranteed the amount of resource requested, but may burst up to its specified limits.

For each compute resource, if a limit is specified and a request is omitted, the request will default to the limit.

Possible resources include (case insensitive): Use "kubectl api-resources" for a complete list of supported resources..

kubectl set resources (-f FILENAME | TYPE NAME)  ([--limits=LIMITS & --requests=REQUESTS]

Examples

  # Set a deployments nginx container cpu limits to "200m" and memory to "512Mi"
  kubectl set resources deployment nginx -c=nginx --limits=cpu=200m,memory=512Mi
  
  # Set the resource request and limits for all containers in nginx
  kubectl set resources deployment nginx --limits=cpu=200m,memory=512Mi --requests=cpu=100m,memory=256Mi
  
  # Remove the resource requests for resources on containers in nginx
  kubectl set resources deployment nginx --limits=cpu=0,memory=0 --requests=cpu=0,memory=0
  
  # Print the result (in yaml format) of updating nginx container limits from a local, without hitting the server
  kubectl set resources -f path/to/file.yaml --limits=cpu=200m,memory=512Mi --local -o yaml

Options

--all
	Select all resources, in the namespace of the specified resource types
--allow-missing-template-keys Default: 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.
-c, --containers string Default: "*"
	The names of containers in the selected pod templates to change, all containers are selected by default - may use wildcards
--dry-run string[="unchanged"] Default: "none"

--field-manager string Default: "kubectl-set"
	Name of the manager used to track field ownership.
-f, --filename strings
	Filename, directory, or URL to files identifying the resource to get from a server.
-h, --help
	help for resources
-k, --kustomize string
	Process the kustomization directory. This flag can't be used together with -f or -R.
--limits string
	The resource requirement requests for this container. For example, 'cpu=100m,memory=256Mi'. Note that server side components may assign requests depending on the server configuration, such as limit ranges.
--local
	If true, set resources will NOT contact api-server but run locally.
-o, --output string
	Output format. One of: (json, yaml, name, go-template, go-template-file, template, templatefile, jsonpath, jsonpath-as-json, jsonpath-file).
-R, --recursive
	Process the directory used in -f, --filename recursively. Useful when you want to manage related manifests organized within the same directory.
--requests string
	The resource requirement requests for this container. For example, 'cpu=100m,memory=256Mi'. Note that server side components may assign requests depending on the server configuration, such as limit ranges.
-l, --selector string
	Selector (label query) to filter on, supports '=', '==', and '!='.(e.g. -l key1=value1,key2=value2). Matching objects must satisfy all of the specified label constraints.
--show-managed-fields
	If true, keep the managedFields when printing objects in JSON or YAML format.
--template string
	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].

--as string

--context string
	The name of the kubeconfig context to use
--default-not-ready-toleration-seconds int Default: 300
	Indicates the tolerationSeconds of the toleration for notReady:NoExecute that is added by default to every pod that does not already have such a toleration.
--default-unreachable-toleration-seconds int Default: 300
	Indicates the tolerationSeconds of the toleration for unreachable:NoExecute that is added by default to every pod that does not already have such a toleration.
--disable-compression
	If true, opt-out of response compression for all requests to the server
--insecure-skip-tls-verify
	If true, the server's certificate will not be checked for validity. This will make your HTTPS connections insecure
--kubeconfig string
	Path to the kubeconfig file to use for CLI requests.
--match-server-version
	Require server version to match client version
-n, --namespace string
	If present, the namespace scope for this CLI request
--password string
	Password for basic authentication to the API server
--profile string Default: "none"

--profile-output string Default: "profile.pprof"
	Name of the file to write the profile to
--request-timeout string Default: "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 string
	The address and port of the Kubernetes API server
--storage-driver-buffer-duration duration Default: 1m0s
