kubectl set resources

Synopsis

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): Use “kubectl api-resources” for a complete list of supported resources..

  1. kubectl set resources (-f FILENAME | TYPE NAME)  ([--limits=LIMITS & --requests=REQUESTS]

Examples

  1.   # Set a deployments nginx container cpu limits to "200m" and memory to "512Mi"
  2.   kubectl set resources deployment nginx -c=nginx --limits=cpu=200m,memory=512Mi
  4.   # Set the resource request and limits for all containers in nginx
  5.   kubectl set resources deployment nginx --limits=cpu=200m,memory=512Mi --requests=cpu=100m,memory=256Mi
  7.   # Remove the resource requests for resources on containers in nginx
  8.   kubectl set resources deployment nginx --limits=cpu=0,memory=0 --requests=cpu=0,memory=0
  10.   # Print the result (in yaml format) of updating nginx container limits from a local, without hitting the server
  11.   kubectl set resources -f path/to/file.yaml --limits=cpu=200m,memory=512Mi --local -o yaml

Options

help for resources

-k, —kustomize string

Process the kustomization directory. This flag can’t be used together with -f or -R.

—limits string

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

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

—requests string

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 string

Selector (label query) to filter on, supports ‘=’, ‘==’, and ‘!=’.(e.g. -l key1=value1,key2=value2). Matching objects must satisfy all of the specified label constraints.

—default-not-ready-toleration-seconds int     Default: 300

—default-unreachable-toleration-seconds int     Default: 300

Indicates the tolerationSeconds of the toleration for unreachable:NoExecute that is added by default to every pod that does not already have such a toleration.

—disable-compression
