9 kubectl autoscale - Auto-scale a deployment, replica set, stateful set,
10 or replication controller
11
15 kubectl autoscale [OPTIONS]
16
20 Creates an autoscaler that automatically chooses and sets the number of
21 pods that run in a Kubernetes cluster.
22 Looks up a deployment, replica set, stateful set, or replication con‐
25 troller by name and creates an autoscaler that uses the given resource
26 as a reference. An autoscaler can automatically increase or decrease
27 number of pods deployed within the system as needed.
28
32 --allow-missing-template-keys=true If true, ignore any errors in
33 templates when a field or map key is missing in the template. Only ap‐
34 plies to golang and jsonpath output formats.
35 --cpu-percent=-1 The target average CPU utilization (represented
38 as a percent of requested CPU) over all the pods. If it's not specified
39 or negative, a default autoscaling policy will be used.
40 --dry-run="none" Must be "none", "server", or "client". If client
43 strategy, only print the object that would be sent, without sending it.
44 If server strategy, submit server-side request without persisting the
45 resource.
46 --field-manager="kubectl-autoscale" Name of the manager used to
49 track field ownership.
50 -f, --filename=[] Filename, directory, or URL to files identifying
53 the resource to autoscale.
54 -k, --kustomize="" Process the kustomization directory. This flag
57 can't be used together with -f or -R.
58 --max=-1 The upper limit for the number of pods that can be set by
61 the autoscaler. Required.
62 --min=-1 The lower limit for the number of pods that can be set by
65 the autoscaler. If it's not specified or negative, the server will ap‐
66 ply a default value.
67 --name="" The name for the newly created object. If not specified,
70 the name of the input resource will be used.
71 -o, --output="" Output format. One of: (json, yaml, name, go-tem‐
74 plate, go-template-file, template, templatefile, jsonpath, jsonpath-as-
75 json, jsonpath-file).
76 --record=false Record current kubectl command in the resource an‐
79 notation. If set to false, do not record the command. If set to true,
80 record the command. If not set, default to updating the existing anno‐
81 tation value only if one already exists.
82 -R, --recursive=false Process the directory used in -f, --filename
85 recursively. Useful when you want to manage related manifests organized
86 within the same directory.
87 --save-config=false If true, the configuration of current object
90 will be saved in its annotation. Otherwise, the annotation will be un‐
91 changed. This flag is useful when you want to perform kubectl apply on
92 this object in the future.
93 --show-managed-fields=false If true, keep the managedFields when
96 printing objects in JSON or YAML format.
97 --template="" Template string or path to template file to use when
100 -o=go-template, -o=go-template-file. The template format is golang tem‐
101 plates [http://golang.org/pkg/text/template/#pkg-overview].
102
106 --as="" Username to impersonate for the operation. User could be a

126 --client-certificate="" Path to a client certificate file for TLS
129 --client-key="" Path to a client key file for TLS
132 --cluster="" The name of the kubeconfig cluster to use
135 --context="" The name of the kubeconfig context to use
138 --disable-compression=false If true, opt-out of response compres‐
141 sion for all requests to the server
142 --insecure-skip-tls-verify=false If true, the server's certificate
145 will not be checked for validity. This will make your HTTPS connections
146 insecure
147 --kubeconfig="" Path to the kubeconfig file to use for CLI re‐
150 quests.
151 --match-server-version=false Require server version to match
154 client version
155 -n, --namespace="" If present, the namespace scope for this CLI
158 request
159 --password="" Password for basic authentication to the API server
162 --profile="none" Name of profile to capture. One of
165 (none|cpu|heap|goroutine|threadcreate|block|mutex)
166 --profile-output="profile.pprof" Name of the file to write the
169 profile to
170 --request-timeout="0" The length of time to wait before giving up
173 on a single server request. Non-zero values should contain a corre‐

175 out requests.
176 -s, --server="" The address and port of the Kubernetes API server
179 --tls-server-name="" Server name to use for server certificate

184 --token="" Bearer token for authentication to the API server
187 --user="" The name of the kubeconfig user to use
190 --username="" Username for basic authentication to the API server
193 --version=false Print version information and quit
196 --warnings-as-errors=false Treat warnings received from the server
199 as errors and exit with a non-zero exit code

204 # Auto scale a deployment "foo", with the number of pods between 2 and 10, no target CPU utilization specified so a default autoscaling policy will be used
205 kubectl autoscale deployment foo --min=2 --max=10
206 # Auto scale a replication controller "foo", with the number of pods between 1 and 5, target CPU utilization at 80%
208 kubectl autoscale rc foo --max=5 --cpu-percent=80
