Add alpha to deploy command when http2 option is true

[simoneb]

Is there a way to execute the beta version of the gcloud application when clicking the cloud run button?

[jamesward]

Once you are in Cloud Shell's CLI?

[simoneb]

From the cloud run button. It seems that clicking the button always executes the command in the shell with the "stable" version of the gcloud command. I'm asking if there's a way to make it execute gcloud beta instead.

[jamesward]

Under the covers Cloud Run Button actually doesn't call gcloud it calls the APIs directly. If you are adding a button to something and want to call gcloud beta you can from custom scripts: https://github.com/GoogleCloudPlatform/cloud-run-button#customizing-deployment-parameters

If you want to add something to Cloud Run Button to do a beta thing, then we'd have to just translate what you want to do to an API call.

I can't see a way to provide custom parameters to cloud, can you provide an example?

[jamesward]

Like you want to tweak the gcloud run deploy command that Cloud Run Button "runs"? If so, yeah there isn't a way to do that without explicitly adding support for what you need to Cloud Run Button. We recently added the new --use-http2 flag and if you want to see what was needed, see: https://github.com/GoogleCloudPlatform/cloud-run-button/pull/203/files

What flag are you looking for?

[simoneb]

As far as I understand, http2 is only supported by gcloud beta. If you try to run an app with http2 using plain gcloud you'll get this in the cloud shell:

Error: error attempting to read the app.json from the cloned repository: failed to parse app.json file: failed to parse app.json: json: unknown field "http2"

I'm trying the button for: https://github.com/GoogleCloudPlatform/kotlin-samples/tree/master/run/grpc-hello-world-bidi-streaming

(It did work but maybe our latest change was rolled back.)

[simoneb]

I was trying this, which seems to be similar, and I got that error https://github.com/GoogleCloudPlatform/golang-samples/tree/master/run/h2c

[jamesward]

Oh! The app.json option is in the wrong place there. Sending a PR to that repo. One sec.

[jamesward]

It needs to be nested in an options block. Try my fork: https://github.com/jamesward/golang-samples/tree/patch-1/run/h2c

[jamesward]

But you are right that running the presented deploy command does indeed fail and we should fix that.

[ ! ] FYI, running the following command:
        gcloud run deploy h2c\
          --project=jw-demo\
          --platform=managed\
          --region=us-central1\
          --image=gcr.io/jw-demo/h2c\
          --allow-unauthenticated\
          --use-http2

gcloud run deploy h2c\
           --project=jw-demo\
           --platform=managed\
           --region=us-central1\
           --image=gcr.io/jw-demo/h2c\
           --allow-unauthenticated\
           --use-http2

ERROR: (gcloud.beta.run.deploy) The `--use-http2` flag is only supported in the alpha release track on the fully m
anaged version of Cloud Run. Use `gcloud alpha` to set `--use-http2` on Cloud Run (fully managed). Alternatively, 
specify `--platform gke` or run `gcloud config set run/platform gke`.

Trying again with gcloud alpha run deploy ... works. So we should adapt the commands we show to account for this.

This is what I was trying to say since my first post.

[jamesward]

Makes sense now. Thanks for reporting!
