kubectl rolling-update — Perform a rolling update of the given ReplicationController.

Synopsis

kubectl rolling-update [Options]

Description

Perform a rolling update of the given ReplicationController.

Replaces the specified replication controller with a new replication controller by updating one pod at a time to use the new PodTemplate. The new-controller.json must specify the same namespace as the existing replication controller and overwrite at least one (common) label in its replicaSelector.

Options

--container=""
Container name which will have its image upgraded. Only relevant when --image is specified, ignored otherwise. Required when using --image on a multi-container pod
--deployment-label-key="deployment"
The key to use to differentiate between two different controllers, default 'deployment'. Only relevant when --image is specified, ignored otherwise
--dry-run=false
If true, only print the object that would be sent, without sending it.
-f, --filename=[]
Filename or URL to file to use to create the new replication controller.
--image=""
Image to use for upgrading the replication controller. Must be distinct from the existing image (either new image or new image tag). Can not be used with --filename/-f
--image-pull-policy=""
Explicit policy for when to pull container images. Required when --image is same as existing image, ignored otherwise.
--include-extended-apis=true
If true, include definitions of new APIs via calls to the API server. [default true]
--no-headers=false
When using the default output, don't print headers.
-o, --output=""
Output format. One of: json|yaml|wide|name|go-template=...|go-template-file=...|jsonpath=...|jsonpath-file=... See golang template [ ⟨http://golang.org/pkg/text/template/#pk…⟩] and jsonpath template [ ⟨http://releases.k8s.io/release-1.3/docs…⟩].
--output-version=""
Output the formatted object with the given group version (for ex: 'extensions/v1beta1').
--poll-interval=3s
Time delay between polling for replication controller status after the update. Valid time units are "ns", "us" (or "µs"), "ms", "s", "m", "h".
--rollback=false
If true, this is a request to abort an existing rollout that is partially rolled out. It effectively reverses current and next and runs a rollout
--schema-cache-dir=" /.kube/schema"
If non-empty, load/store cached API schemas in this directory, default is '$HOME/.kube/schema'
-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/#pk…⟩].
--timeout=5m0s
Max time to wait for a replication controller to update before giving up. Valid time units are "ns", "us" (or "µs"), "ms", "s", "m", "h".
--update-period=1m0s
Time to wait between updating pods. Valid time units are "ns", "us" (or "µs"), "ms", "s", "m", "h".
--validate=true
If true, use a schema to validate the input before sending it

Example

# Update pods of frontend-v1 using new replication controller data in frontend-v2.json.
kubectl rolling-update frontend-v1 -f frontend-v2.json

# Update pods of frontend-v1 using JSON data passed into stdin.
cat frontend-v2.json | kubectl rolling-update frontend-v1 -f -

# Update the pods of frontend-v1 to frontend-v2 by just changing the image, and switching the
# name of the replication controller.
kubectl rolling-update frontend-v1 frontend-v2 --image=image:v2

# Update the pods of frontend by just changing the image, and keeping the old name.
kubectl rolling-update frontend --image=image:v2

# Abort and reverse an existing rollout in progress (from frontend-v1 to frontend-v2).
kubectl rolling-update frontend-v1 frontend-v2 --rollback
