## 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
|
|
|
|
```
|
|
|
|
