Runtime configuration and scaling

What you’ll learn

How to scale your application in CodeNOW in order to make it more efficient or more performant.

Prerequisites

• Created application and Application components
• You are ready to deploy your application.

Parameters

Summary

CodeNOW lets you set the following parameters:

• Number of running instances: number of pods to be run, the default value is 1
• CPU request: number of computing units that are guaranteed to be allocated
• CPU limit: upper boundary of computing units to be allocated
• Memory request: amount of memory that is guaranteed to be allocated
• Memory limit: upper boundary of memory to be allocated

CPU Units

In Kubernetes, CPU requirements are measured using the cpu unit or its fractions, where 1 cpu = 1 vCPU/Core (for cloud providers) = 1 hyperthread (for bare-metal processors). For more information, see Kubernetes documentation.

CodeNOW lets you can specify the CPU requirements using the following units:

Unit	Description	Size [cpu]
cpu	cpu/core	1
m	millicpu/millicore	1/1000

Memory Units

Memory is measured using bytes or multiples of bytes.

CodeNOW lets you specify the memory requirements using the following units:

Unit	Description	Size [bytes]
B	Byte	1
K	Kilobyte	10^3
M	Megabyte	10^6
G	Gigabyte	10^9
T	Terabyte	10^12
P	Petabyte	10^15
E	Exabyte	10^18
KiB	Kibibyte	2^10
MiB	Mebibyte	2^20
GiB	Gibibyte	2^30
TiB	Tebibyte	2^40
PiB	Pebibyte	2^50
EiB	Exbibyte	2^60

Set runtime configuration for component

1. Go to the Runtime Configuration section in the detail of your application component.
2. Select the branch for which you want to set the runtime configuration and click on Edit.
   • default values and your changes will affect the Branch configuration
3. Set the desired values for the parameters and click on Confirm.
