NAME
kubectl set resources - Update resource requests/limits on objects with pod templates

SYNOPSIS
kubectl set resources [OPTIONS]

DESCRIPTION
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..

OPTIONS
--all=false
    Select all resources, in the namespace of the specified resource types

--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.

-c, --containers="*"
    The names of containers in the selected pod templates to change, all containers are selected by default - may use wildcards

--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.

--field-manager="kubectl-set"
    Name of the manager used to track field ownership.

-f, --filename=[]
    Filename, directory, or URL to files identifying the resource to get from a server.

-k, --kustomize=""
    Process the kustomization directory. This flag can't be used together with -f or -R.

--limits=""
    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=false
    If true, set resources will NOT contact api-server but run locally.

-o, --output=""
    Output format. One of: (json, yaml, kyaml, name, go-template, go-template-file, template, templatefile, jsonpath, jsonpath-as-json, jsonpath-file).

--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.

-R, --recursive=false
    Process the directory used in -f, --filename recursively. Useful when you want to manage related manifests organized within the same directory.

--requests=""
    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=""
    Selector (label query) to filter on, supports '=', '==', '!=', 'in', 'notin'.(e.g. -l key1=value1,key2=value2,key3 in (value3)). Matching objects must satisfy all of the specified label constraints.

--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].

OPTIONS INHERITED FROM PARENT COMMANDS
--as=""
    Username to impersonate for the operation. 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. This will make your HTTPS connections 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 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
      # 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
