## kubectl autoscale
Auto-scale a replication controller
Auto-scale a deployment or replication controller
### Synopsis
Creates an autoscaler that automatically chooses and sets the number of pods that run in a kubernetes cluster.
Looks up a replication controller by name and creates an autoscaler that uses this replication controller as a reference.
Looks up a deployment or replication controller by name and creates an autoscaler that uses this deployment or replication controller as a reference.
An autoscaler can automatically increase or decrease number of pods deployed within the system as needed.
```
{% raw %}
kubectl autoscale (-f FILENAME | TYPE NAME | TYPE/NAME) [--min=MINPODS] --max=MAXPODS [--cpu-percent=CPU] [flags]
{% endraw %}
```
### Examples
```
{% raw %}
# Auto scale a replication controller "foo", with the number of pods between 2 to 10, target CPU utilization at a default value that server applies:
$ kubectl autoscale rc foo --min=2 --max=10
# Auto scale a deployment "foo", with the number of pods between 2 to 10, target CPU utilization at a default value that server applies:
kubectl autoscale deployment foo --min=2 --max=10
# Auto scale a replication controller "foo", with the number of pods between 1 to 5, target CPU utilization at 80%:
$ kubectl autoscale rc foo --max=5 --cpu-percent=80
{% endraw %}
kubectl autoscale rc foo --max=5 --cpu-percent=80
```
### Options
```
{% raw %}
--cpu-percent=-1: The target average CPU utilization (represented as a percent of requested CPU) over all the pods. If it's not specified or negative, the server will apply a default value.
--dry-run[=false]: If true, only print the object that would be sent, without creating it.
-f, --filename=[]: Filename, directory, or URL to a file identifying the resource to get from a server.
-f, --filename=[]: Filename, directory, or URL to a file identifying the resource to autoscale.
--generator="horizontalpodautoscaler/v1beta1": The name of the API generator to use. Currently there is only 1 generator.
--max=-1: The upper limit for the number of pods that can be set by the autoscaler. Required.
--min=-1: The lower limit for the number of pods that can be set by the autoscaler. If it's not specified or negative, the server will apply a default value.
--name="": The name for the newly created object. If not specified, the name of the input resource will be used.
--no-headers[=false]: When using the default output, don't print headers.
-o, --output="": Output format. One of: json|yaml|wide|name|go-template=...|go-template-file=...|jsonpath=...|jsonpath-file=... See golang template [http://golang.org/pkg/text/template/#pkg-overview] and jsonpath template [http://releases.k8s.io/release-1.1/docs/user-guide/jsonpath.md].
-o, --output="": Output format. One of: json|yaml|wide|name|go-template=...|go-template-file=...|jsonpath=...|jsonpath-file=... See golang template [http://golang.org/pkg/text/template/#pkg-overview] and jsonpath template [http://releases.k8s.io/release-1.2/docs/user-guide/jsonpath.md].
--output-version="": Output the formatted object with the given version (default api-version).
--record[=false]: Record current kubectl command in the resource annotation.
--save-config[=false]: If true, the configuration of current object will be saved in its annotation. This is useful when you want to perform kubectl apply on this object in the future.
-a, --show-all[=false]: When printing, show all resources (default hide terminated pods.)
--sort-by="": If non-empty, sort list types using this field specification. The field specification is expressed as a JSONPath expression (e.g. 'ObjectMeta.Name'). The field in the API resource specified by this JSONPath expression must be an integer or a string.
--show-labels[=false]: When printing, show all labels as the last column (default hide labels column)
--sort-by="": 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="": 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].
{% endraw %}
```
### Options inherited from parent commands
```
{% raw %}

--api-version="": The API version to use when talking to the server
--certificate-authority="": Path to a cert. file for the certificate authority.
--client-certificate="": Path to a client key file for TLS.
--client-certificate="": Path to a client certificate file for TLS.
--client-key="": Path to a client key file for TLS.
