### Name

`kf scale` - Change the horizontal or vertical scale of an App without downtime.

### Synopsis

```
kf scale APP_NAME [flags]
```

### Description

Scaling an App will change the number of desired instances and/or the
requested resources for each instance.

Instances are replaced one at a time, always ensuring that the desired
number of instances are healthy. This property is upheld by running one
additional instance of the App and swapping it out for an old instance.

The operation completes once all instances have been replaced.

### Examples

```
# Display current scale settings
kf scale myapp
# Scale to exactly 3 instances
kf scale myapp --instances 3
```
