6 kubectl set resources - Update resource requests/limits on objects with
7 pod templates
8
12 kubectl set resources [OPTIONS]
13
17 Specify compute resource requirements (cpu, memory) for any resource
18 that defines a pod template. If a pod is successfully scheduled, it is
19 guaranteed the amount of resource requested, but may burst up to its
20 specified limits.
21 for each compute resource, if a limit is specified and a request is
24 omitted, the request will default to the limit.
25 Possible resources include (case insensitive): Use "kubectl
28 api-resources" for a complete list of supported resources..
29
33 --all=false
34 Select all resources, including uninitialized ones, in the names‐
35 pace of the specified resource types
36 --allow-missing-template-keys=true
39 If true, ignore any errors in templates when a field or map key is
40 missing in the template. Only applies to golang and jsonpath output
41 formats.
42 -c, --containers="*"
45 The names of containers in the selected pod templates to change,
46 all containers are selected by default - may use wildcards
47 --dry-run=false
50 If true, only print the object that would be sent, without sending
51 it.
52 -f, --filename=[]
55 Filename, directory, or URL to files identifying the resource to
56 get from a server.
57 --include-uninitialized=false
60 If true, the kubectl command applies to uninitialized objects. If
61 explicitly set to false, this flag overrides other flags that make the
62 kubectl commands apply to uninitialized objects, e.g., "--all". Objects
63 with empty metadata.initializers are regarded as initialized.
64 -k, --kustomize=""
67 Process the kustomization directory. This flag can't be used
68 together with -f or -R.
69 --limits=""
72 The resource requirement requests for this container. For example,
73 'cpu=100m,memory=256Mi'. Note that server side components may assign
74 requests depending on the server configuration, such as limit ranges.
75 --local=false
78 If true, set resources will NOT contact api-server but run locally.
79 -o, --output=""
82 Output format. One of: json|yaml|name|go-template|go-tem‐
83 plate-file|template|templatefile|jsonpath|jsonpath-file.
84 --record=false
87 Record current kubectl command in the resource annotation. If set
88 to false, do not record the command. If set to true, record the com‐
89 mand. If not set, default to updating the existing annotation value
90 only if one already exists.
91 -R, --recursive=false
94 Process the directory used in -f, --filename recursively. Useful
95 when you want to manage related manifests organized within the same
96 directory.
97 --requests=""
100 The resource requirement requests for this container. For example,
101 'cpu=100m,memory=256Mi'. Note that server side components may assign
102 requests depending on the server configuration, such as limit ranges.
103 -l, --selector=""
106 Selector (label query) to filter on, not including uninitialized
107 ones,supports '=', '==', and '!='.(e.g. -l key1=value1,key2=value2)
