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
35 namespace 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="none"
50 Must be "none", "server", or "client". If client strategy, only
51 print the object that would be sent, without sending it. If server
52 strategy, submit server-side request without persisting the resource.
53 -f, --filename=[]

57 get from a server.
58 -k, --kustomize=""
61 Process the kustomization directory. This flag can't be used
62 together with -f or -R.
63 --limits=""
66 The resource requirement requests for this container. For example,
67 'cpu=100m,memory=256Mi'. Note that server side components may assign
68 requests depending on the server configuration, such as limit ranges.
69 --local=false
72 If true, set resources will NOT contact api-server but run locally.
73 -o, --output=""
76 Output format. One of:
77 json|yaml|name|go-template|go-template-file|template|templatefile|jsonpath|jsonpath-file.
78 --record=false
81 Record current kubectl command in the resource annotation. If set
82 to false, do not record the command. If set to true, record the
83 command. If not set, default to updating the existing annotation value
84 only if one already exists.
85 -R, --recursive=false
88 Process the directory used in -f, --filename recursively. Useful
89 when you want to manage related manifests organized within the same
90 directory.
91 --requests=""
94 The resource requirement requests for this container. For example,
95 'cpu=100m,memory=256Mi'. Note that server side components may assign
96 requests depending on the server configuration, such as limit ranges.
