|
### Synopsis
|
||

|
|

||
|
|
Create and run a particular image, possibly replicated.
|
||
|
|
Creates a replication controller to manage the created container(s).
|
||
|
|
|
||
|
|
```
|
||
|
|
kubectl run NAME --image=image [--port=port] [--replicas=replicas] [--dry-run=bool] [--overrides=inline-json]
|
||
|
|
```

### Examples

// Starts a replicated instance of nginx.
|
||
|
|
$ kubectl run nginx --image=nginx --replicas=5
|

|
|
|

||
|
|
$ kubectl run nginx --image=nginx --dry-run

||
|
|
|
||
|
|
// Start a single instance of nginx, but overload the spec of the replication controller with a partial set of values parsed from JSON.
