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
Flags
