Vault csi provider in gcp

I'm trying to run Vault CSI provider but I'm getting the following error in my app pod:

MountVolume.SetUp failed for volume "secrets-store-inline" : rpc error: code = Unknown desc = failed to mount secrets store objects for pod vault/my-service-9b78df688-8xnql, err: rpc error: code = Unknown desc = error making mount request: failed to login: Error making API request. Namespace: vault URL: POST https://vault.craft-code.com/v1/auth/gcp/login Code: 400. Errors: * unable to get public key for signed JWT: unable to get public key "xxxxx" for JWT subject "system:serviceaccount:vault:service-web-app": googleapi: Error 400: Request contains an invalid argument.

According to the doc, before login to vault google cloud should issue jwt credential to be able to login in vault. I'm ussing terraform but I don't know how to do that. Could something explain it?

Once the service account and key have been created, the private key can be used to generate the JWT token needed to login to Vault.

To configure a Google Cloud service account to issue a JWT token before it can be used to login to Vault, you need to complete the following steps:

  • Create a service account in the Google Cloud platform.
  • Download the JSON key file associated with the service account.
  • Configure the Vault server to use the GCP auth backend and provide the JSON key file for the service account.
  • Configure the Google Cloud IAM roles for the service account in order to grant it access to the Vault server.
  • Get the JWT token from the service account and use it to authenticate with Vault.
