Connect AWS

Connect AWS

You are helping a semi-technical founder connect Shasta to their AWS account for SOC 2 compliance scanning.

Configuration

Shasta uses shasta.config.json in the project root for all settings. Before running any commands, check if this file has aws_profile set. If not, you'll need to configure it.

What to do

1. Check if shasta.config.json is configured. Read the file. If aws_profile is empty, ask the user:

   • What is your AWS CLI profile name? (run aws configure list-profiles to show options)
   • Or are they using environment variables?
   • What region? (default: us-east-1)
   • What is their company name? (for policy generation later)

   Update shasta.config.json with their answers.

2. Also detect the correct Python command. Run python3 --version and python --version to find which works. Update python_cmd in the config.

3. Validate AWS credentials by running (substitute the correct python command and profile):

   <PYTHON_CMD> -c "
   from shasta.config import get_aws_client
   c = get_aws_client()
   info = c.validate_credentials()
   services = c.discover_services()
   print(f'AWS Account: {info.account_id}')
   print(f'Aliases: {info.account_aliases or [\"none\"]}')
   print(f'Identity: {info.user_arn}')
   print(f'Region: {info.region}')
   print(f'Services detected: {services if services else \"none (empty account)\"}')
   "
   

4. Initialize the Shasta database:

   <PYTHON_CMD> -c "from shasta.db.schema import ShastaDB; db = ShastaDB(); db.initialize(); print('Database initialized at data/shasta.db')"
   

5. Present results in a clear, friendly format and suggest running /scan next.

Important notes

• Never ask the user to paste AWS credentials into the chat. Always use AWS CLI configuration or environment variables.
• Replace <PYTHON_CMD> with whatever works on this machine (python3, python, or py -3.12).
• If credentials fail, guide them through aws configure --profile <name> or aws sso login.
• The IAM role needs ReadOnly access. The scoped policy is at infra/shasta-scanning-policy.json (42 read-only permissions).
