Update the number of container instances that run in a container group (corresponding IBM Containers command: `cf ic group update <option> <group>`). Note: You can run only one update at a time. The desired number is the number of container instances that you require. It must be within the current limits of Max and Min. To increase the number of desired container instances above the Max value, you must first execute an update on the Max value. Once this update is completed, you can increase the desired number of container instances.
