Service account

Alternatively, you can give Portworx access to the GCP API server via an account file and environment variables. First, you will need to create a service account in GCP and download the account file.

To access the GCP API server, Portworx needs a service account with the following roles

Owner and Compute Admin Roles
These Roles provides Portworx access to the Google Cloud Storage APIs to provision persistent disks. Make sure the service account created below has these roles.
Cloud KMS predefined roles
Following predefined roles provide Portworx access to the Google Cloud KMS APIs to manage secrets.
```
roles/cloudkms.cryptoKeyEncrypterDecrypter
roles/cloudkms.publicKeyViewer
```

Follow these steps to create a service account and download its corresponding account file:

Create a service account in the "Service Account" section that has the above permissions.
Go to IAM & admin -> Service Accounts -> (Instance Service Account) -> Select "Create Key" and download the .json file.
