CloudRun local beta code dev - metadata server cannot be reached

[mauermbq]

Hi,

according to https://cloud.google.com/sdk/gcloud/reference/beta/code/dev

it's possible to build and run service on local machine.

To access Google Cloud Platform services with the current user's credentials following the documentation I invoke the following commands:

gcloud auth application-default login
gcloud beta code dev --dockerfile=Dockerfile --application-default-credential

However this lead to an error which says that meta data server cannot be reached:

google.auth.exceptions.DefaultCredentialsError: Neither metadata server or valid service account credentials are found.

The service works well on the cloud with same user (CloudRun by IAP).

Hi @mauermbq,

Welcome to Google Cloud Community!

Based on your error, you need to download a service account JSON keyfile and point it using an environment variable. Your code should look like this:

$ export GOOGLE_APPLICATION_CREDENTIALS="/path/to/keyfile.json"

You may want to check these documentation on authentication for additional information.

Hi robertcarlos, thank you. I'm referring to ADC: https://cloud.google.com/docs/authentication/provide-credentials-adc

AND to https://cloud.google.com/sdk/gcloud/reference/beta/code/dev

According to this 

gcloud auth application-default login

generates credentials for client libraries in: `$HOME/.config/gcloud/application_default_credentials.json`

and

gcloud beta code dev --dockerfile=<path_to_dockerfile> --application-default-credential

obtains the application default credentials. So following the other docs no need for an addition env variable.
