## kubectl autoscale
|
|
|
|
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 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.
|
|
|
|
```
|
|
kubectl autoscale (-f FILENAME | TYPE NAME | TYPE/NAME) [--min=MINPODS] --max=MAXPODS [--cpu-percent=CPU] [flags]
|
|
```
|
|
|
|
### Examples
|
|
|
|
```
|
|
# 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
|
|
```
|
|
|
|
### Options
|
|
|
|
```
|
|
--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 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/HEAD/docs/user-guide/jsonpath.md].
|
|
--output-version="": Output the formatted object with the given version (default api-version).
|
|
--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.
|
|
--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
|
|
|
|
```
|
|
--alsologtostderr[=false]: log to standard error as well as files
