## kubectl rolling-update
|
|
|
|
Perform a rolling update of the given ReplicationController
|
|
|
|
### Synopsis
|
|
|
|
|
|
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.

|
|
|
|
```
|
|
kubectl rolling-update OLD_CONTROLLER_NAME ([NEW_CONTROLLER_NAME] --image=NEW_CONTAINER_IMAGE | -f NEW_CONTROLLER_SPEC)
|
|
```
|
|
|
|
### Examples
|
|
|
|
```
|
|
# 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
|
|
```
|
|
|
|
### Options
|
|
|
|
```
|
|
--container string 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 string The key to use to differentiate between two different controllers, default 'deployment'. Only relevant when --image is specified, ignored otherwise (default "deployment")
|
|
--dry-run If true, only print the object that would be sent, without sending it.
|
|
-f, --filename stringSlice Filename or URL to file to use to create the new replication controller.
|
|
--image string 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 string Explicit policy for when to pull container images. Required when --image is same as existing image, ignored otherwise.
|
|
--no-headers When using the default or custom-column output format, don't print headers.
|
|
-o, --output string 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 string Output the formatted object with the given group version (for ex: 'extensions/v1beta1').
|
|
--poll-interval duration Time delay between polling for replication controller status after the update. Valid time units are "ns", "us" (or "µs"), "ms", "s", "m", "h". (default 3s)
|
|
--rollback 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 string If non-empty, load/store cached API schemas in this directory, default is '$HOME/.kube/schema' (default "~/.kube/schema")
|
|
-a, --show-all When printing, show all resources (default hide terminated pods.)
|
|
--show-labels When printing, show all labels as the last column (default hide labels column)
|
|
--sort-by string 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 string 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].
|
|
--timeout duration 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". (default 5m0s)
|
|
--update-period duration Time to wait between updating pods. Valid time units are "ns", "us" (or "µs"), "ms", "s", "m", "h". (default 1m0s)
|
|
--validate If true, use a schema to validate the input before sending it (default true)
|
|
```
