Deploy two versions of same app at same time

[Mahmmoud Mahdi]

Hello All,

Is possible to deploy two version of same app at same time using gcloud command

Thanks

There shouldn't be any issues with deploying the same code twice or more as it will result in different App Engine versions. It doesn't seem like there is an option to deploy multiple versions of the same services to App Engine though you can deploy different services in one gcloud command[1].

Can you please provide more context regarding the project, service, version, and instance with respect to the deployment?

To automate deployment of multiple versions and testing the speed of process in parallel. Running the deploy of second version fail until the first one finished.

How to deploy version similar to the following commands without facing error:

gcloud app deploy --version v1 --quiet &
gcloud app deploy --version v2 --quiet

Many Thanks

What is the use of deploying two versions at the same time, and not one after the other? An issue description needs the support of a well-motivated use-case to prove its point and convince. A detailed description, preferably in step-by-step format, would be appreciated.
