NAME

6       oc scale - Change the number of pods in a deployment
7

SYNOPSIS

11       oc scale [OPTIONS]
12
13
14

DESCRIPTION

16       Set a new size for a deployment or replication controller
17
18
19       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
24
25       Note that scaling a deployment configuration with no  deployments  will
26       update the desired replicas in the configuration template.
27
28
29       Supported resources: ["deployment" "replicaset" "replicationcontroller"
30       "statefulset" "deploymentconfig"]
31

33

OPTIONS

35       --all=false
36           Select all resources in the namespace  of  the  specified  resource
37       types
38
39
40       --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
45
46       --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
50
51       -f, --filename=[]
52           Filename, directory, or URL to files identifying  the  resource  to
53       set a new size
54
55
56       -o, --output=""
57           Output  format. One of: json|yaml|name|template|go-template|go-tem‐
58       plate-file|templatefile|jsonpath|jsonpath-file.
59
60
61       --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
67
68       -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 di‐
71       rectory.
72
73
74       --replicas=0
75           The new desired number of replicas. Required.
76
77
78       --resource-version=""
79           Precondition  for  resource  version. Requires that the current re‐
80       source version match this value in order to scale.
81
82
83       -l, --selector=""
84           Selector (label query)  to  filter  on,  supports  '=',  '==',  and
85       '!='.(e.g. -l key1=value1,key2=value2)
86
87
88       --template=""
89           Template  string  or  path  to template file to use when -o=go-tem‐
90       plate, -o=go-template-file. The template format is golang  templates  [
91http://golang.org/pkg/text/template/#pkg-overview⟩].
92
93
94       --timeout=0
95           The  length  of time to wait before giving up on a scale operation,
96       zero means don't wait. Any other values should contain a  corresponding
97       time unit (e.g. 1s, 2m, 3h).
