Development

Setting up

Log in gcloud with a Service Account

Instead of using your personal credential to log in, it's recommended to use a Service Account instead.

A new Service Account and proper permissions can be created using the following commands. PROJECT-ID is the (non-numeric) identifier of your GCP project. This assumes that you're already logged in with gcloud.

gcloud iam service-accounts create \
  marketplace-dev-robot \
  --project PROJECT-ID \
  --display-name "GCP Marketplace development robot"

gcloud projects add-iam-policy-binding PROJECT-ID \
  --member serviceAccount:[email protected] \
  --role roles/editor

gcloud projects add-iam-policy-binding PROJECT-ID \
  --member serviceAccount:[email protected] \
  --role roles/container.admin

The created Service Account email will be [email protected]. Note that you can replace marketplace-dev-robot with another name.

Now you can switch gcloud to using the Service Account by creating and downloading a one-time key, and activate it.

gcloud iam service-accounts keys create ~/marketplace-dev-robot-key.json \
  --iam-account [email protected]

gcloud auth activate-service-account \
  --key-file ~/marketplace-dev-robot-key.json

You should keep ~/marketplace-dev-robot-key.json credential key in a safe location. Note that this is the only copy; the generated key cannot be downloaded again.

Log in application default credentials for kubectl

kubectl connecting to GKE requires application default credentials. Log in using the following command:

gcloud auth application-default login

Running the doctor command

At the very least, you need to connect to a GKE cluster. Follow this instruction to ensure you have a properly setup environment.
