I'm trying to deploy an app engine application, but no matter which code I'm trying to deploy, even if it's taken from their samples at:

https://github.com/GoogleCloudPlatform/golang-samples

I get the same error:

Step #1: error building image: getting stage builder for stage 0: MANIFEST_UNKNOWN: "Manifest with digest 'sha256:249859465bcde1cb15128ff0d9eb2bb54de67f72a834a7576e6649cfe0a27698' has media type 'application/vnd.docker.distribution.manifest.list.v2+json', but client accepts 'application/vnd.docker.distribution.manifest.v2+json'."

I'm not good at devops, so no idea howto work this around

I encountered the same issue when deploying on AppEngine Flexible today. I don't think it's something you can do. I opened an issue on github hopefully the google cloud team will fix it fast.

For info, the issue the OP has is that when running gcloud app deploy app.yaml he expects the app do be deployed.

Cloud Build tries to fetch an image that has a media type it does not understand.

Got: application/vnd.docker.distribution.manifest.list.v2+json Expected: application/vnd.docker.distribution.manifest.v2+json

I've encountered the same issue recently. After some digging, it turns out that the issue was reported on the GCP Issue Tracker already: https://issuetracker.google.com/issues/171756486

As a workaround update the app.yaml file to contain runtime: go1.13.

Update:

Deploying with runtime: go1.13 only works for the first run. It will still fail when attempting to re-deploy.

Update 2:

The Google team has rolled back the issue on their side. (source)

To make it work you will need to downgrade your gcloud to version 315.0.0:

gcloud components update --version 315.0.0

After that, the deployment will proceed as usual.

Google responded to this bug ticket saying to downgrade to gcloud 315.0.0 which i just tested and it worked.

gcloud components update --version 315.0.0

I faced the same problem and figure it up by adding

service: default

in my app.yaml
