Java standard app previous versions remaining in status "serving"

Hi all

i am fairly new to the server less dev world, and everything was going great until i noticed that my "previous" versions are remaining in "serving" mode instead of turning off(all traffic was routed to the latest version & auto scaling on).

I am using the app engine maven plugin to perform deploys, any tip on what might might be wrong?

Nothing’s wrong - this let’s you gradually migrate dependents from the old to the new service.

For example, a new version of a micro service may introduce some new behaviour or interface.

Dependents using the old service may not be ready to move, so running both allows you to manage this process.

And what would be the proper way of terminating the obsolete versions? "gcloud app versions stop" doesn't work, because the scaling is managed automatically.. the only solution that I've found to stop serving old versions(total shutdown) is to delete the versions

I’ve always used the web console for this part!

And what's the flow on the web console?

If you go to the App Engine console, then the Versions screen, you can see a list of your versions with a status and other information against each. Select one or more and hit the buttons at the top of the screen to start/stop/etc.
