Nebius

Service account

To use Service Account authentication, follow these steps:

1. Create a Service Account using the Nebius web console.

2. Generate PEM Keys:

openssl genrsa -out private.pem 4096
openssl rsa -in private.pem -outform PEM -pubout -out public.pem

3. Generate and Save the Credentials File:

• Save the file as ~/.nebius/credentials.json.

• Ensure the file matches the expected format below:

{
    "subject-credentials": {
        "alg": "RS256",
        "private-key": "PKCS#8 PEM with new lines escaped as \n",
        "kid": "public-key-id",
        "iss": "service-account-id",
        "sub": "service-account-id"
    }
}

Important Notes:

• The NEBIUS_IAM_TOKEN file, if present, will take priority for authentication.
