+.SH NAME
+.PP
+kubectl autoscale \- Auto\-scale a replication controller
+
+
+.SH SYNOPSIS
+.PP
+\fBkubectl autoscale\fP [OPTIONS]
+
+
+.SH DESCRIPTION
+.PP
+Creates an autoscaler that automatically chooses and sets the number of pods that run in a kubernetes cluster.
+
+.PP
+Looks up a replication controller by name and creates an autoscaler that uses this replication controller as a reference.
+An autoscaler can automatically increase or decrease number of pods deployed within the system as needed.
+
+
+.SH OPTIONS
+.PP
+\fB\-\-cpu\-percent\fP=\-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.
+
+.PP
+\fB\-\-dry\-run\fP=false
+    If true, only print the object that would be sent, without creating it.
+
+.PP
+\fB\-f\fP, \fB\-\-filename\fP=[]
+    Filename, directory, or URL to a file identifying the resource to get from a server.
+
+.PP
+\fB\-\-generator\fP="horizontalpodautoscaler/v1beta1"
+    The name of the API generator to use. Currently there is only 1 generator.
+
+.PP
+\fB\-\-max\fP=\-1
+    The upper limit for the number of pods that can be set by the autoscaler. Required.
+
+.PP
+\fB\-\-min\fP=\-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.
+
+.PP
+\fB\-\-name\fP=""
+    The name for the newly created object. If not specified, the name of the input resource will be used.
+
+.PP
+\fB\-\-no\-headers\fP=false
+    When using the default output, don't print headers.
+
+.PP
+\fB\-o\fP, \fB\-\-output\fP=""
+    Output format. One of: json|yaml|wide|name|go\-template=...|go\-template\-file=...|jsonpath=...|jsonpath\-file=... See golang template [
+\[la]http://golang.org/pkg/text/template/#pkg-overview\[ra]] and jsonpath template [
+\[la]http://releases.k8s.io/HEAD/docs/user-guide/jsonpath.md\[ra]].
+
+.PP
+\fB\-\-output\-version\fP=""
+    Output the formatted object with the given version (default api\-version).
+
+.PP
+\fB\-a\fP, \fB\-\-show\-all\fP=false
+    When printing, show all resources (default hide terminated pods.)
+
+.PP
+\fB\-\-sort\-by\fP=""
+    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.
+
+.PP
+\fB\-t\fP, \fB\-\-template\fP=""
+    Template string or path to template file to use when \-o=go\-template, \-o=go\-template\-file. The template format is golang templates [

+.RS
+
+.nf
+# 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 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
