kubectl scale
Set a new size for a Deployment, ReplicaSet, Replication Controller, or Job
Synopsis
Set a new size for a Deployment, ReplicaSet, Replication Controller, or Job.
Scale also allows users to specify one or more preconditions for the scale action. If –current-replicas or –resource-version is specified, it is validated before the scale is attempted, and it is guaranteed that the precondition holds true when the scale is sent to the server.
kubectl scale [--resource-version=version] [--current-replicas=count] --replicas=COUNT (-f FILENAME | TYPE NAME)
Examples
# Scale a replicaset named 'foo' to 3.
kubectl scale --replicas=3 rs/foo
# Scale a resource identified by type and name specified in "foo.yaml" to 3.
kubectl scale --replicas=3 -f foo.yaml
# If the deployment named mysql's current size is 2, scale mysql to 3.
kubectl scale --current-replicas=2 --replicas=3 deployment/mysql
# Scale multiple replication controllers.
kubectl scale --replicas=5 rc/foo rc/bar rc/baz
# Scale job named 'cron' to 3.
kubectl scale --replicas=3 job/cron
Options
--current-replicas int Precondition for current size. Requires that the current size of the resource match this value in order to scale. (default -1)
-f, --filename value Filename, directory, or URL to a file identifying the resource to set a new size (default [])
--include-extended-apis If true, include definitions of new APIs via calls to the API server. [default true] (default true)
-o, --output string Output mode. Use "-o name" for shorter output (resource/name).
--record 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 Process the directory used in -f, --filename recursively. Useful when you want to manage related manifests organized within the same directory.
--replicas int The new desired number of replicas. Required. (default -1)
--resource-version string Precondition for resource version. Requires that the current resource version match this value in order to scale.
--timeout duration The length of time to wait before giving up on a scale operation, zero means don't wait. Any other values should contain a corresponding time unit (e.g. 1s, 2m, 3h). (default 0s)
