Environment Variables

Objective

This guide explains how to use Environment Variables on Ruk-Com Cloud PaaS, with ordered procedures and practical verification points.

Before you begin

• Sign in with an account permitted to manage the relevant environment.
• Confirm the target environment, region and resources before saving changes.
• Create a backup or rollback plan before changing a production system.

Environment variables are used to store the values of frequently used parameters that software programs use to run. Using such placeholders makes your application more convenient and flexible.

The most common use of variables is to quickly modify a specific value that is used multiple times in your application code. If you wantCreate variables in the environment yourself.You can follow the instructions from the attached link.

Another case for variables is to config the application through a set of pre-defined values (enable/disable features, change behavior, etc.). Ruk-Com Cloud PaaS supplements most of the verified software stacks with a number of default variables that developers can use to help host the application.
