With gcd.sh local (gcd-rpc 1.0.0) errors always #1236

susanlinsfu · 2016-04-15T20:01:55Z

I am using gcloud-node v.0.30.3 and since it doesn't support gRPC I am using gcd-rpc for my local datastore. This is only occurring on windows (gcd.cmd). I run some operation it always returns 'No connection could be made because the target machine actively refused it". The strange thing though is it completes the operation always. The error shows, but if I have some console output it always shows and if I get entities it will display the entities in the console.

Can you share the exact output of the error messages, both on the client and on the emulator output.

On the gcd when I make a request:

I have the same issue, expect i'm using the default gcloud beta emulators datastore start command to start the emulator.

This is the output from the datastore starting:

The admin interface can be accessed without issues, so I'm pretty sure the datastore emulator is fine.

susanlinsfu · 2016-04-16T18:06:07Z

@zlepper I believe the gcloud emulator doesn't support gRPC, hence we can't use the gcloud emulator and must use the gcd tool.

Additionally, we are now using gRPC to give a performance boost to your Datastore calls. As of now, the gcloud SDK does not have a gRPC emulator, meaning if you wish to use a localhost backend instead of the upstream API, you will have to use the gcd.sh tool directly.

https://github.com/GoogleCloudPlatform/gcloud-node/releases/tag/v0.30.0

Please keep in mind there is no admin console with the gcd tool .

zlepper · 2016-04-16T18:50:54Z

@susanlinsfu internally it seems to call the same cmd file as your command do?

And shouldn't the node docs then be updated to reflect the proper way to use gcloud-node with the datastore emulator?

stephenplusplus · 2016-04-16T18:57:26Z

@zlepper as the release notes say, this is a temporary workaround as the Datastore emulator from inside the gcloud SDK does not support gRPC. Do we have docs that say how to use the emulator currently? We could leave a note there about the workaround. I haven't received any time line for when the SDK emulator will support gRPC.

zlepper · 2016-04-16T20:15:32Z

There is a note about how to specify an api endpoint, which is pretty much using the datastore emulator, as far as I know.
The datastore emulator docs themselves https://cloud.google.com/datastore/docs/tools/datastore-emulator do not say anything about how to connect with any service.

And I just (a couple of days ago) started using gcloud, so I missed the release note when I was searching around for this issue originally.

zlepper · 2016-04-16T20:29:44Z

Switching to use the gdc.cmd tool directly, as provided in the link on the release page, this happens:

@zlepper thanks for pointing that out. I have a PR that will do a better job of explaining: #1231

As for the issues with the output, I have to deflect to @pcostell on what these might mean.

pcostell · 2016-04-18T16:27:25Z

Yikes, those are some gnarly stack traces. Can you share your gcloud-node code that you are running so I can try to reproduce it?

sebelga · 2016-04-18T17:47:14Z

Just sharing a few things I realised to make it work (here on OS X):

Check that you don't have anything running on port 8080 (I had Jenkins running without noticing and was blocking all the calls to the gcd)... arg! :)
Had to start the command with Admin privilege (sudo) (although the local folder is in Home directory)
the Api endpoint is "http://localhost:8080" although the gcd console says API endpoint: http://localhost:8080/datastore

@pcostell Datastore setup code: https://gist.github.com/zlepper/59c7b11d60c86bb9cd199c5162b9733d
And the error happens whenever I try to make a query to the datastore.

You need to set the apiPoint inside the datastore() instantiation.
Like this:

var gc = gcloud(options);  // remove apiPoint from your options object
var datastore = gc.datastore({
    apiEndpoint: 'http://localhost:8080'
});

@sebelga if you set the env var, you don't need to use apiEndpoint:

If you are using a library that supports the DATASTORE_EMULATOR_HOST environment variable, run:

  export DATASTORE_EMULATOR_HOST=localhost:8080

@pcostell should I move this issue over to google-cloud-datastore?

zlepper · 2016-04-19T17:39:58Z

@sebelga Settings the apiEndpoint on the datastoreOptions instead did not help.

@stephenplusplus Only settings the env var and not specifying the apiEndpoint at all did not help either. Gives the same error as I mentioned with the stacktrace earlier.

This issue was moved to googleapis/google-cloud-datastore#110

stephenplusplus · 2016-04-19T17:42:57Z

Yeah, I don't know if that will fix the error, but it should be all you need from the standpoint of connecting to the emulator with gcloud-node. I'm going to move this issue over to that other repo, hopefully getting some more eyes on the problem. Of course, if it turns out to be an issue with this library, we will re-investigate from this end.
