6 oc autoscale - Autoscale a deployment config, deployment, replication
7 controller, or replica set
8
12 oc autoscale [OPTIONS]
13
17 Autoscale a deployment config or replication controller.
18 Looks up a deployment config or replication controller by name and cre‐
21 ates an autoscaler that uses this deployment config or replication con‐
22 troller as a reference. An autoscaler can automatically increase or de‐
23 crease number of pods deployed within the system as needed.
24
28 --allow-missing-template-keys=true
29 If true, ignore any errors in templates when a field or map key is
30 missing in the template. Only applies to golang and jsonpath output
31 formats.
32 --cpu-percent=-1
35 The target average CPU utilization (represented as a percent of re‐
36 quested CPU) over all the pods. If it's not specified or negative, a
37 default autoscaling policy will be used.
38 --dry-run=false
41 If true, only print the object that would be sent, without sending
42 it.
43 -f, --filename=[]
46 Filename, directory, or URL to files identifying the resource to
47 autoscale.

51 The name of the API generator to use. Currently there is only 1
52 generator.
53 --max=-1
56 The upper limit for the number of pods that can be set by the au‐
57 toscaler. Required.
58 --min=-1
61 The lower limit for the number of pods that can be set by the au‐
62 toscaler. If it's not specified or negative, the server will apply a
63 default value.
64 --name=""
67 The name for the newly created object. If not specified, the name
68 of the input resource will be used.
69 -o, --output=""

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