from a flat structure into a hierarchical, category-based structure to improve maintainability and scalability. + +## Motivation + +With 87/198 APIs implemented (44%) and projection to reach 198 files

category has its own mod.rs + +## Migration Details + +- **Files Moved**: 81 files in builders/, 81 in client/, 78 in response/ +- **Method Used**: `git mv` to preserve history +- **Breaking Changes**: None - all public APIs remain accessible via re-exports +- **Tests**: All 216 unit tests pass ✅ + +## Future APIs + +With this structure, the remaining 111 APIs will be added to existing

Security + +- **Never hardcode credentials** - Use environment variables or secure configuration +- **Use service accounts** for applications instead of user credentials +- **Apply least privilege** - Grant only necessary permissions +- **Rotate credentials** regularly +- **Enable TLS** for production deployments + +### 2. Service Account Design + +- Create separate service accounts for each application +- Set expiration dates for temporary access +- Use descriptive names and descriptions +- Review and audit service account usage regularly + +### 3. Policy Management + +- Start with restrictive policies and expand as needed +- Test policies thoroughly before production deployment +- Document policy purposes and owners +- Use groups for managing permissions at scale + +### 4. Configuration Management + +- Always check if `restart_required` is true after configuration changes +- Test configuration changes in non-production environments first +- Keep backups of configuration before major changes +- Use configuration history APIs to track changes +- Use `help_config_kv` to understand configuration options before modifying +- Restore previous configurations using `restore_config_history_kv` if needed +- Clear old configuration history periodically to save space + +### 5. Monitoring + +- Regularly check server health and storage usage +- Monitor failed authentication attempts +- Track quota usage to prevent storage exhaustion +- Use metrics APIs for integration with monitoring systems + +### 6. Profiling + +- Use profiling sparingly - it impacts server performance +- Profile for short durations (5-10 seconds) to minimize impact +- Save profile data to files for offline analysis +- Use appropriate profiler types for specific issues: + - CPU profiling for performance bottlenecks + - Memory profiling for memory leaks + - Mutex/Block profiling for concurrency issues + - Goroutine dumps for deadlock analysis + +### 7. Log Configuration + +- Enable API logging for audit and debugging purposes +- Set appropriate drive limits to prevent disk exhaustion +- Configure flush intervals based on log volume +- Disable audit logging if not required to save resources +- Use error logging to track server issues + +### 8. Identity Provider Configuration + +- Test IDP configurations thoroughly before deployment +- Use `check_idp_config` to validate LDAP connectivity +- Always check `restart_required` after IDP changes +- Document IDP configurations for operational reference +- Use separate IDP configurations for different environments +- Secure IDP credentials properly (lookup_bind_password, client_secret) +- Test authentication flows after configuration changes + +### 9. KMS & Encryption Management + +- **Key Security**: Never expose encryption keys in logs or error messages +- **Key Rotation**: Implement regular key rotation policies for enhanced security +- **Policy Design**: Use least-privilege policies for KMS identities +- **Monitoring**: Regularly check KMS metrics for anomalies or failed requests +- **Identity Management**: Assign policies to identities rather than embedding permissions +- **Pattern Filtering**: Use pattern filtering when listing keys, policies, or identities to reduce response size +- **Key Status**: Verify key status before critical operations to ensure encryption/decryption capability +- **Audit**: Track all KMS operations for compliance and security auditing +- **Backup**: Document key IDs and policies for disaster recovery planning +- **Testing**: Test KMS operations in non-production environments before deployment + +## Environment Variables + +Common environment variables for configuration: + +```bash +export MINIO_ENDPOINT="http://localhost:9000" +export MINIO_ROOT_USER="minioadmin" +export MINIO_ROOT_PASSWORD="minioadmin" +``` + +## Testing + +When testing against shared MinIO instances: + +- Clean up resources after tests +- Use unique names to avoid conflicts +- Handle transient failures (eventual consistency) +- Avoid disruptive operations (restart, stop) + +## Further Reading + +- [MinIO Admin API Documentation](https://min.io/docs/minio/linux/reference/minio-mc-admin.html) +- [IAM Policy Documentation](https://min.io/docs/minio/linux/administration/identity-access-management/policy-based-access-control.html) +- [Service Account Documentation](https://min.io/docs/minio/linux/administration/identity-access-management/iam-service-accounts.html) +- [MinIO Configuration Reference](https://min.io/docs/minio/linux/reference/minio-server/settings.html) diff --git a/docs/madmin_error_handling_examples.md b/docs/madmin_error_handling_examples.md new file mode 100644 index 00000000..44160819 --- /dev/null +++ b/docs/madmin_error_handling_examples.md @@ -0,0 +1,417 @@ +# MinIO Admin Error Handling Examples + +This guide shows how to use the strongly-typed error variants in the MinIO Rust SDK's Admin API. + +## Overview + +The SDK provides strongly-typed error variants for common MinIO Admin API errors, making it easy to handle specific error cases programmatically using pattern matching. + +## Basic Error Handling + +### Example 1: Handling User Not Found + +```rust +use minio::s3::error::{Error, MadminServerError};
