9 kubectl set resources - Update resource requests/limits on objects with
10 pod templates
11
15 kubectl set resources [OPTIONS]
16
20 Specify compute resource requirements (CPU, memory) for any resource
21 that defines a pod template. If a pod is successfully scheduled, it is
22 guaranteed the amount of resource requested, but may burst up to its
23 specified limits.
24 For each compute resource, if a limit is specified and a request is
27 omitted, the request will default to the limit.
28 Possible resources include (case insensitive): Use "kubectl api-re‐
31 sources" for a complete list of supported resources..
32
36 --all=false Select all resources, in the namespace of the speci‐
37 fied resource types
38 --allow-missing-template-keys=true If true, ignore any errors in
41 templates when a field or map key is missing in the template. Only ap‐
42 plies to golang and jsonpath output formats.
43 -c, --containers="*" The names of containers in the selected pod
46 templates to change, all containers are selected by default - may use
47 wildcards
48 --dry-run="none" Must be "none", "server", or "client". If client
51 strategy, only print the object that would be sent, without sending it.
52 If server strategy, submit server-side request without persisting the
53 resource.
54 --field-manager="kubectl-set" Name of the manager used to track
57 field ownership.
58 -f, --filename=[] Filename, directory, or URL to files identifying
61 the resource to get from a server.
62 -k, --kustomize="" Process the kustomization directory. This flag
65 can't be used together with -f or -R.
66 --limits="" The resource requirement requests for this container.
69 For example, 'cpu=100m,memory=256Mi'. Note that server side components
70 may assign requests depending on the server configuration, such as
71 limit ranges.
72 --local=false If true, set resources will NOT contact api-server
75 but run locally.
76 -o, --output="" Output format. One of: (json, yaml, name, go-tem‐
79 plate, go-template-file, template, templatefile, jsonpath, jsonpath-as-
80 json, jsonpath-file).
81 --record=false Record current kubectl command in the resource an‐
84 notation. If set to false, do not record the command. If set to true,
85 record the command. If not set, default to updating the existing anno‐
86 tation value only if one already exists.
87 -R, --recursive=false Process the directory used in -f, --filename
90 recursively. Useful when you want to manage related manifests organized
91 within the same directory.
92 --requests="" The resource requirement requests for this con‐
95 tainer. For example, 'cpu=100m,memory=256Mi'. Note that server side
96 components may assign requests depending on the server configuration,
97 such as limit ranges.
98 -l, --selector="" Selector (label query) to filter on, supports
101 '=', '==', and '!='.(e.g. -l key1=value1,key2=value2). Matching objects
102 must satisfy all of the specified label constraints.
103 --show-managed-fields=false If true, keep the managedFields when
106 printing objects in JSON or YAML format.
107 --template="" Template string or path to template file to use when
110 -o=go-template, -o=go-template-file. The template format is golang tem‐
111 plates [http://golang.org/pkg/text/template/#pkg-overview].
112
116 --as="" Username to impersonate for the operation. User could be a
117 regular user or a service account in a namespace.
118 --as-group=[] Group to impersonate for the operation, this flag
121 can be repeated to specify multiple groups.
122 --as-uid="" UID to impersonate for the operation.
125 --azure-container-registry-config="" Path to the file containing
128 Azure container registry configuration information.
129 --cache-dir="/builddir/.kube/cache" Default cache directory
132 --certificate-authority="" Path to a cert file for the certificate
135 authority
136 --client-certificate="" Path to a client certificate file for TLS
139 --client-key="" Path to a client key file for TLS
142 --cluster="" The name of the kubeconfig cluster to use
145 --context="" The name of the kubeconfig context to use
148 --disable-compression=false If true, opt-out of response compres‐
151 sion for all requests to the server
152 --insecure-skip-tls-verify=false If true, the server's certificate
155 will not be checked for validity. This will make your HTTPS connections
156 insecure
157 --kubeconfig="" Path to the kubeconfig file to use for CLI re‐
160 quests.
161 --match-server-version=false Require server version to match
164 client version
165 -n, --namespace="" If present, the namespace scope for this CLI
168 request
169 --password="" Password for basic authentication to the API server
172 --profile="none" Name of profile to capture. One of
175 (none|cpu|heap|goroutine|threadcreate|block|mutex)
176 --profile-output="profile.pprof" Name of the file to write the
179 profile to
180 --request-timeout="0" The length of time to wait before giving up
183 on a single server request. Non-zero values should contain a corre‐
184 sponding time unit (e.g. 1s, 2m, 3h). A value of zero means don't time‐
185 out requests.
186 -s, --server="" The address and port of the Kubernetes API server
189 --tls-server-name="" Server name to use for server certificate
192 validation. If it is not provided, the hostname used to contact the

194 --token="" Bearer token for authentication to the API server
197 --user="" The name of the kubeconfig user to use
200 --username="" Username for basic authentication to the API server
