6 oc scale - Change the number of pods in a deployment
7
11 oc scale [OPTIONS]
12
16 Set a new size for a deployment or replication controller
17 Scale also allows users to specify one or more preconditions for the
20 scale action. If --current-replicas or --resource-version is specified,
21 it is validated before the scale is attempted, and it is guaranteed
22 that the precondition holds true when the scale is sent to the server.
23 Note that scaling a deployment configuration with no deployments will
26 update the desired replicas in the configuration template.
27 Supported resources: ["deployment" "replicaset" "replicationcontroller"
30 "statefulset" "deploymentconfig"]
31
35 --all=false
36 Select all resources in the namespace of the specified resource
37 types
38 --allow-missing-template-keys=true
41 If true, ignore any errors in templates when a field or map key is
42 missing in the template. Only applies to golang and jsonpath output
43 formats.
44 --current-replicas=-1
47 Precondition for current size. Requires that the current size of
48 the resource match this value in order to scale.
49 -f, --filename=[]
52 Filename, directory, or URL to files identifying the resource to
53 set a new size
54 -o, --output=""
57 Output format. One of: json|yaml|name|template|go-template|go-tem‐
58 plate-file|templatefile|jsonpath-file|jsonpath.
59 --record=false
62 Record current kubectl command in the resource annotation. If set
63 to false, do not record the command. If set to true, record the com‐
64 mand. If not set, default to updating the existing annotation value
65 only if one already exists.
66 -R, --recursive=false
69 Process the directory used in -f, --filename recursively. Useful
70 when you want to manage related manifests organized within the same
71 directory.
72 --replicas=0
