kubectl set resources

kubectl set resources

update resource requests/limits on objects with pod templates

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): replicationcontroller, deployment, daemonset, job, replicaset.

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
  -c, --containers string       The names of containers in the selected pod templates to change, all containers are selected by default - may use wildcards (default "*")
      --dry-run                 If true, only print the object that would be sent, without sending it.
  -f, --filename stringSlice    Filename, directory, or URL to files identifying the resource to get from a server.
      --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.
      --no-headers              When using the default or custom-column output format, don't print headers.
  -o, --output string           Output format. One of: json|yaml|wide|name|custom-columns=...|custom-columns-file=...|go-template=...|go-template-file=...|jsonpath=...|jsonpath-file=... See custom columns [http://kubernetes.io/docs/user-guide/kubectl-overview/#custom-columns], golang template [http://golang.org/pkg/text/template/#pkg-overview] and jsonpath template [http://kubernetes.io/docs/user-guide/jsonpath].
      --output-version string   Output the formatted object with the given group version (for ex: 'extensions/v1beta1').
      --record                  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               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
  -a, --show-all                When printing, show all resources (default hide terminated pods.)
      --show-labels             When printing, show all labels as the last column (default hide labels column)
      --sort-by string          If non-empty, sort list types using this field specification.  The field specification is expressed as a JSONPath expression (e.g. '{.metadata.name}'). The field in the API resource specified by this JSONPath expression must be an integer or a string.
      --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].
