How to mapping default services to other services ?

[Kanti Vekariya]

I want to replace default service to the first service how to do?

[David (Google Cloud Support)]

Services are listed from top to bottom based on how recently they were deployed, meaning that recently deployed services appear at the top and older services appear at the bottom.

In java using std env you need to change the service (module) name to "default" in appengine-web.xml, ex:

<appengine-web-app xmlns="http://appengine.google.com/ns/1.0">
    <application>your app</application>
    <module>default</module>
    

And of course change the name to another name on your current default module.

Should be simiular in other languages as well, for 2:nd gen or flex env I don't know, probably you need

to change something in a yaml file or whatever popular these days.
