6 kubectl autoscale - Auto-scale a Deployment, ReplicaSet, or Replica‐
7 tionController
8
12 kubectl autoscale [OPTIONS]
13
17 Creates an autoscaler that automatically chooses and sets the number of
18 pods that run in a kubernetes cluster.
19 Looks up a Deployment, ReplicaSet, or ReplicationController by name and
22 creates an autoscaler that uses the given resource as a reference. An
23 autoscaler can automatically increase or decrease number of pods
24 deployed within the system as needed.
25
29 --allow-missing-template-keys=true
30 If true, ignore any errors in templates when a field or map key is
31 missing in the template. Only applies to golang and jsonpath output
32 formats.
33 --cpu-percent=-1
36 The target average CPU utilization (represented as a percent of
37 requested CPU) over all the pods. If it's not specified or negative, a
38 default autoscaling policy will be used.
39 --dry-run=false
42 If true, only print the object that would be sent, without sending
43 it.
44 -f, --filename=[]
47 Filename, directory, or URL to files identifying the resource to
48 autoscale.

52 The name of the API generator to use. Currently there is only 1
53 generator.
54 --max=-1
57 The upper limit for the number of pods that can be set by the
58 autoscaler. Required.
59 --min=-1

63 autoscaler. If it's not specified or negative, the server will apply a
64 default value.

80 mand. If not set, default to updating the existing annotation value
81 only if one already exists.
82 -R, --recursive=false
85 Process the directory used in -f, --filename recursively. Useful
86 when you want to manage related manifests organized within the same
87 directory.
88 --save-config=false
91 If true, the configuration of current object will be saved in its
92 annotation. Otherwise, the annotation will be unchanged. This flag is
93 useful when you want to perform kubectl apply on this object in the
94 future.
