Set a new size for a deployment, replica set, replication controller, or stateful set.

Scale also allows users to specify one or more preconditions for the scale action.

If –current-replicas or –resource-version is specified, it is validated before the scale is attempted, and it is guaranteed that the precondition holds true when the scale is sent to the server.

Syntax

werf kubectl scale [--resource-version=version] [--current-replicas=count] --replicas=COUNT (-f FILENAME | TYPE NAME) [options]

Examples

  # Scale a replica set named 'foo' to 3
  kubectl scale --replicas=3 rs/foo
  
  # Scale a resource identified by type and name specified in "foo.yaml" to 3
  kubectl scale --replicas=3 -f foo.yaml
  
  # If the deployment named mysql's current size is 2, scale mysql to 3
  kubectl scale --current-replicas=2 --replicas=3 deployment/mysql
  
  # Scale multiple replication controllers
  kubectl scale --replicas=5 rc/foo rc/bar rc/baz
  
  # Scale stateful set named 'web' to 3
  kubectl scale --replicas=3 statefulset/web

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.
      --current-replicas=-1
            Precondition for current size. Requires that the current size of the resource match     
            this value in order to scale. -1 (default) for no condition.
      --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.
  -f, --filename=[]
            Filename, directory, or URL to files identifying the resource to set a new size
  -k, --kustomize=''
            Process the kustomization directory. This flag can`t be used together with -f or -R.
  -o, --output=''
            Output format. One of: json|yaml|name|go-template|go-template-file|template|templatefile
            |jsonpath|jsonpath-as-json|jsonpath-file.
  -R, --recursive=false
            Process the directory used in -f, --filename recursively. Useful when you want to       
            manage related manifests organized within the same directory.
      --replicas=0
            The new desired number of replicas. Required.
      --resource-version=''
            Precondition for resource version. Requires that the current resource version match     
            this value in order to scale.
  -l, --selector=''
            Selector (label query) to filter on, supports `=`, `==`, and `!=`.(e.g. -l              
            key1=value1,key2=value2)
      --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].
      --timeout=0s
            The length of time to wait before giving up on a scale operation, zero means don`t      
            wait. Any other values should contain a corresponding time unit (e.g. 1s, 2m, 3h).

Options inherited from parent commands

            account in a namespace.

            groups.
