OPENSHIFT KUBE SET(1)

NAME

openshift kube set resources - update resource requests/limits on objects with pod templates

SYNOPSIS

openshift kube set resources [OPTIONS]

DESCRIPTION

Specify compute resource requirements (cpu, memory) for any resource that defines a pod template. If a pod is successfully scheduled, it is guaranteed the amount of resource requested, but may burst up to its specified limits.

for each compute resource, if a limit is specified and a request is omitted, the request will default to the limit.

Possible resources include (case insensitive): replicationcontroller, deployment, daemonset, job, replicaset.

OPTIONS

--all=false
    select all resources in the namespace of the specified resource types

--allow-missing-template-keys=true
    If true, ignore any errors in templates when a field or map key is missing in the template. Only applies to golang and jsonpath output formats.

-c, --containers="*"
    The names of containers in the selected pod templates to change, all containers are selected by default - may use wildcards

--dry-run=false
    If true, only print the object that would be sent, without sending it.

-f, --filename=[]
    Filename, directory, or URL to files identifying the resource to get from a server.

--limits=""
    The resource requirement requests for this container. For example, 'cpu=100m,memory=256Mi'. Note that server side components may assign requests depending on the server configuration, such as limit ranges.

--local=false
    If true, set resources will NOT contact api-server but run locally.

--no-headers=false
    When using the default or custom-column output format, don't print headers.

-o, --output=""
    Output format. One of: json|yaml|wide|name|custom-columns=...|custom-columns-file=...|go-template=...|go-template-file=...|jsonpath=...|jsonpath-file=... See custom columns [ ⟨http://kubernetes.io/docs/user-guide/kubectl-overview/#custom-columns⟩], golang template [ ⟨http://golang.org/pkg/text/template/#pkg-overview⟩] and jsonpath template [ ⟨http://kubernetes.io/docs/user-guide/jsonpath⟩].

--output-version=""
    Output the formatted object with the given group version (for ex: 'extensions/v1beta1').

--record=false
    Record current kubectl command in the resource annotation. If set to false, do not record the command. If set to true, record the command. If not set, default to updating the existing annotation value only if one already exists.

-R, --recursive=false
    Process the directory used in -f, --filename recursively. Useful when you want to manage related manifests organized within the same directory.

--requests=""
    The resource requirement requests for this container. For example, 'cpu=100m,memory=256Mi'. Note that server side components may assign requests depending on the server configuration, such as limit ranges.

-l, --selector=""
    Selector (label query) to filter on

-a, --show-all=false
    When printing, show all resources (default hide terminated pods.)

--show-labels=false
    When printing, show all labels as the last column (default hide labels column)

--sort-by=""
    If non-empty, sort list types using this field specification. The field specification is expressed as a JSONPath expression (e.g. '{.metadata.name}'). The field in the API resource specified by this JSONPath expression must be an integer or a string.

--template=""
    Template string or path to template file to use when -o=go-template, -o=go-template-file. The template format is golang templates [ ⟨http://golang.org/pkg/text/template/#pkg-overview⟩].
