⚙️ AWS Configuration

SSO Session Configuration

~/.aws/config:

[sso-session my-company]
sso_start_url = https://my-company.awsapps.com/start
sso_region = us-east-1
sso_registration_scopes = sso:account:access

[profile production-admin]
sso_session = my-company
sso_account_id = 111111111111
sso_role_name = AdministratorAccess
region = us-east-1
output = json

[profile staging-developer]
sso_session = my-company
sso_account_id = 222222222222
sso_role_name = DeveloperAccess
region = us-west-2
output = json

Assume Role Configuration

[profile base]
region = us-east-1

[profile cross-account-admin]
source_profile = base
role_arn = arn:aws:iam::333333333333:role/AdminRole
region = us-east-1

Legacy SSO (without sso-session)

[profile legacy-sso]
sso_start_url = https://my-company.awsapps.com/start

🐛 Troubleshooting

AWS CLI Not Found - E_NO_AWS: AWS CLI v2 not detected

Solution: Install AWS CLI v2 following the official guide

Verify installation:

aws --version  # Should show "aws-cli/2.x.x ..."

No Profiles Available - E_NO_PROFILES: No profiles detected

Solution: Configure at least one profile:

# For SSO
aws configure sso-session

# For legacy SSO
aws configure sso

# For static credentials
aws configure

SSO Login Fails - E_LOGIN_FAIL: SSO login failed

Possible causes:

• Network connectivity issues
• Invalid SSO start URL
• MFA/2FA not completed
• Browser not opening (check firewall/permissions)

Solution:

# Try manual login first
aws sso login --profile your-profile-name

# Check browser permissions
# Ensure port 8080-8090 range is available for OAuth callback

Identity Check Fails - E_STS_FAIL: Unable to fetch identity

Possible causes:

• Credentials expired (SSO token or assume-role session)
• Invalid profile configuration
• Network/VPC issues
• Missing IAM permissions

Solution:

# Force re-authentication
# Press 'l' in awsui to trigger SSO login

# Verify profile configuration
cat ~/.aws/config

# Test manually
aws sts get-caller-identity --profile your-profile-name

Amazon Q Not Available - Amazon Q CLI not available

Solution: Install Amazon Q Developer CLI:

# macOS
brew install amazon-q

# Other platforms: follow official guide
# https://docs.aws.amazon.com/amazonq/latest/qdeveloper-ug/command-line-installing.html

Verify installation:

q --version

🔒 Security

awsui follows AWS security best practices:

• ✅ Credential Handling: Only uses AWS CLI's credential system - no credential storage or caching
• ✅ Temporary Credentials: Leverages AWS STS and SSO for short-lived tokens
• ✅ Read-Only Config: Only reads ~/.aws/config and ~/.aws/credentials - never writes
• ✅ Log Safety: Sensitive data (tokens, secrets) automatically masked in logs
• ✅ Environment Isolation: Supports AWS_CONFIG_FILE and AWS_SHARED_CREDENTIALS_FILE for custom config locations
• ✅ No Network Calls: All AWS operations delegated to official AWS CLI
• ✅ Subprocess Safety: Secure subprocess execution with proper escaping

🎯 Performance

Target metrics:

• Startup time: ≤ 300ms (cold start)
• Search response: ≤ 50ms (keystroke to UI update)
• Profile switch: ≤ 5s (including SSO login if needed)
