Agreed, but a little debugging shows that Google Client Library is trying to 
connect to the actual cloud endpoint of the project: supplying the credentials 
through `gcloud auth application-default login` or `gcloud iam service-accounts 
keys create` results in the test code connecting to the production datastore…

According to 
https://cloud.google.com/docs/authentication/production#finding_credentials_automatically,
 if no credentials are provided the hosting environment should automatically 
provide connection hints for the local resources: I’d expect Java 8 Local 
Development Server to automatically connect  Google Client Library to the local 
Datastore Emulator, replicating the application behaviour when deployed in 
cloud, but that’s apparently not the case.

I’m currently working around the issue by testing locally using both the Local 
Development Server and the standalone Datastore Emulator as:

gcloud beta emulators datastore start \
   —project=project-id \
   --host-port=localhost:8081 \
   --data-dir=target/war

DATASTORE_EMULATOR_HOST=localhost:8081 java_dev_appserver.sh \
   --port=8080 \
  target/war

However, the process is quite cumbersome and difficult to automate: what I’m 
looking for is a way to automatically connect Google Client Library to the 
Datastore Emulator managed by the Java 8 Local Development Server when 
launching the app with something like 
https://github.com/GoogleCloudPlatform/app-maven-plugin, e.g. `mvn 
appengine:run`.

Re: [google-appengine] Re: dev_appserver now compatible with Cloud Datastore Emulator.

[Cosmin Poieană]

Yes, it works! Because the emulator starts, sets the required env vars, 
requirements are installed and finally the app is served, but with stripped 
env vars, then additional ones are taken from app.yaml or manually provided 
by the dev_appserver.py (as above). Don't forget to mention its port also 
with "--datastore_emulator_port 8088" for example.

Actually, "cloud.google.com/go/datastore" should also work. However, at
this moment, you *have to* pass the DATASTORE_EMULATOR_HOST with the
'--env_var' flag to dev_appserver:
 --env_var DATASTORE_EMULATOR_HOST=localhost:8088

Please try this flag, hopefully it should work :)

Dev_appserver currently prunes shell env vars from local golang runtime
process. The '--env_var' flag allows you to pass environment variable to
the local go runtime process.

Re: [google-appengine] Re: dev_appserver now compatible with Cloud Datastore Emulator.

['Kai Wang' via Google App Engine]

Hi Giuliano,

Note that, for app engine standard runtime go, the recommended datastore
library
is
"google.golang.org/appengine/datastore".  I've verified on my side this
library works with dev_appserver + datastore emulator.

As for "cloud.google.com/go/datastore". I am not every sure how to make it
work in App Engine standard app.  I do have verified this cloud library can
speak to the datastore emulator when it is *outside of *App Engine
dev_appserver. Unfortunately I've not been able to make this library work
inside an app engine golang app. Could you kindly attach some  code
snippet, such that run a simple GAE go app with the cloud datastore library?

Detected environment variable DATASTORE_EMULATOR_HOST=localhost:,

FYI, are you sure the emulator ran on localhost: ?

Thank you so much for trying this feature.

I am all ears to follow up :)

[google-appengine] Re: dev_appserver now compatible with Cloud Datastore Emulator.

[Giuliano Ribeiro]

When I setup the local env, see the log:
WARNING  2018-06-01 13:21:25,741 api_server.py:581] Detected environment 
variable DATASTORE_EMULATOR_HOST=localhost:, dev_appserver will speak 
to the Cloud Datastore emulator running on this address. The datastore_path 
/var/folders/n4/vq69gqrn3470jyqdp1sxp2wwgn/T/appengine.None.gribeiro/datastore.db
 
will be neglected.
If you want datastore to store on 
/var/folders/n4/vq69gqrn3470jyqdp1sxp2wwgn/T/appengine.None.gribeiro/datastore.db,
 
remove DATASTORE_EMULATOR_HOST from environment variables and restart 
dev_appserver

And my app still writing/reading from the cloud.

[google-appengine] Re: dev_appserver now compatible with Cloud Datastore Emulator.

['Kai Wang' via Google App Engine]

According to the documentation 
,
 
you need to have the env var "DATASTORE_EMUALTOR_HOST" set. 

Also, FYI, this "cloud.google.com/go/datastore" (officially, it is called 
Google Cloud Client Library), should be able to connect to the datatore 
emulator, no matter the code runs inside or outside of the dev_appserver.

Please check the env var and lmk if they work :)

 You can opt-in to this feature by running:

 By using the --support_datastore_emulator flag, dev_appserver will use 
 Cloud Datastore Emulator for local datastore emulation. You can read more

 The development server and Cloud Datastore Emulator support the

[Giuliano Ribeiro]

Hi Kai Wang, I'm using "cloud.google.com/go/datastore"
As I read in the documentation this datastore package support the emulator, 
I was thinking it should be easy to use. But even enabling the emulator in 
the dev_appserver, my app is reading and writing directly in the cloud, 
ignoring the emulator. 

Thanks,

Hi Glullano,

What go libraries are you using? Is it google.golang.org/appengine/datastore
 (link

Did it store locally before?

You can email  k...@google.com for further details :)

*dev_appserver.py* is a command to start the local development server for
