# Credentials

1. Create a service account for your GCP project as described [here](https://cloud.google.com/iam/docs/creating-managing-service-accounts#iam-service-accounts-create-console) with the following roles (these roles could be more restrictive if required):
   1. `Editor` role.
   2. `Kubernetes Engine Admin` role.
   3. `Container Registry Service Agent` role.
   4. `Storage Admin` role.
   5. `Storage Object Admin` role.
2. Generate a service account key for your service account as described [here](https://cloud.google.com/iam/docs/creating-managing-service-account-keys) and export it as a JSON file.
3. Export the `GOOGLE_APPLICATION_CREDENTIALS` variable and point it to the downloaded service account key from the previous step. For example: `export GOOGLE_APPLICATION_CREDENTIALS=/home/ubuntu/.config/gcloud/sample-269400-9a41792a969b.json`

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.cortexlabs.com/0.30/clusters/gcp/credentials.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
