Application Configuration Group

Since the V5.3 version, Rainbond has added the configuration group function.A configuration group is a set of environment variables that can take effect in some service components under the same application at the same time.Configuration groups are ideal when you need to configure uniform environment variables for many service components.

The configuration items will take effect in the component running environment as environment variables, and support dynamic parsing using${KEY}mode in the component’s environment variables and configuration files.If the same KEY appears, the environment variable of the component has a higher priority.

• Effective component：Select the effective service component of the current configuration group, and automatically read all service components under the current application for the user to choose

It is worth noting that, whether it is a new configuration group or an existing configuration group, the corresponding service components must be updated according to the prompts before it can take effect.The impact of the update operation may be service interruption, and the time of configuration group change needs to be decided by the user
