📄 Description

Summary

This PR introduces comprehensive configuration file support using TOML format, allowing users to configure Ollama settings through config.toml files instead of relying solely on environment variables. This addresses the long-standing need for easier configuration management, particularly for network binding and other server settings.

Problem Statement

Currently, Ollama requires users to manage configuration through environment variables, which presents several challenges:

  • Cross-platform complexity: Different methods required for Windows, macOS, and Linux
  • Network access setup: Complex process to bind to 0.0.0.0:11434 for network access
  • Configuration persistence: No standardized way to version control or share configurations
  • User experience: Steep learning curve for new users setting up network access

Solution

📁 New Configuration File System

Implements TOML-based configuration with the following features:

  • OS-appropriate file locations:

    • Linux: ~/.config/ollama/config.toml, ~/.ollama/config.toml, /etc/ollama/config.toml
    • macOS: ~/Library/Application Support/ollama/config.toml, ~/.config/ollama/config.toml, ~/.ollama/config.toml
    • Windows: %APPDATA%\ollama\config.toml, %USERPROFILE%\.ollama\config.toml

  • Hierarchical precedence: Environment variables > Config file > Defaults

  • Complete backward compatibility: All existing environment variable usage unchanged

🔧 New CLI Commands

  • ollama config show - Display current configuration and sources
  • ollama config init - Create example configuration file with documentation

📝 Configuration Structure

[server]
host = "0.0.0.0:11434"  # Network binding (was OLLAMA_HOST)
origins = ["http://localhost:3000"]  # CORS origins (was OLLAMA_ORIGINS)

[models]
path = "~/.ollama/models"  # Model storage path (was OLLAMA_MODELS)
keep_alive = "5m"          # Memory retention (was OLLAMA_KEEP_ALIVE)
max_loaded_models = 3      # Max concurrent models (was OLLAMA_MAX_LOADED_MODELS)
max_queue = 512           # Request queue size (was OLLAMA_MAX_QUEUE)

[performance]
num_parallel = 4          # Parallel requests (was OLLAMA_NUM_PARALLEL)
gpu_overhead = 0          # GPU memory overhead (was OLLAMA_GPU_OVERHEAD)
flash_attention = false   # Flash attention (was OLLAMA_FLASH_ATTENTION)
kv_cache_type = "f16"    # Cache type (was OLLAMA_KV_CACHE_TYPE)

[logging]
debug = false            # Debug logging (was OLLAMA_DEBUG)

Implementation Details

Files Added/Modified

New Files:

  • envconfig/file_config.go - Core configuration file handling
  • cmd/config.go - CLI commands for configuration management

Modified Files:

  • envconfig/config.go - Updated Var() function to check config files
  • cmd/cmd.go - Added config commands to CLI (if modified)
  • README.md - Added comprehensive configuration documentation

Key Technical Features

  1. Thread-safe configuration loading using sync.Once
  2. Graceful error handling - invalid TOML logs warning, falls back to env vars
  3. Cross-platform path resolution using OS-appropriate standards
  4. Zero performance impact when no config file exists
  5. Comprehensive test coverage including edge cases

Configuration Precedence

The system follows a clear hierarchy:

  1. Environment variables (highest priority - existing behavior)
  2. Configuration file (new capability)
  3. Default values (existing behavior)

This ensures 100% backward compatibility while providing new functionality.

Usage Examples

Before (Environment Variables Only)

# Windows
set OLLAMA_HOST=0.0.0.0:11434
ollama serve

# Linux/macOS
export OLLAMA_HOST=0.0.0.0:11434
ollama serve

After (Configuration File)

# Initialize config file
ollama config init

# Edit ~/.ollama/config.toml:
# [server]
# host = "0.0.0.0:11434"

# Just run - works everywhere
ollama serve

# View current configuration
ollama config show

Benefits

For End Users

  • ✅ Simplified network setup - Edit one line in config file vs platform-specific env var setup
  • ✅ Cross-platform consistency - Same config file works on Windows, macOS, Linux
  • ✅ Version control friendly - Config files can be committed to dotfiles repos
  • ✅ Self-documenting - Generated config includes comments explaining each option

For System Administrators

  • ✅ Standardized deployment - Consistent config management across environments
  • ✅ Environment separation - Easy dev/staging/production config management
  • ✅ Documentation - Clear mapping between env vars and config options

For Developers

  • ✅ Better integration - Easier to build tooling around standardized config files
  • ✅ Testing - Simplified configuration for test scenarios
  • ✅ Distribution - Can ship example configs with applications

Testing

Test Coverage

  • ✅ Configuration file loading from all OS-specific paths
  • ✅ Precedence validation (env vars override config file)
  • ✅ TOML parsing with valid and invalid files
  • ✅ CLI commands (config show, config init)
  • ✅ Cross-platform path resolution
  • ✅ Thread safety and performance

Manual Testing

  • ✅ Network binding works with config file
  • ✅ Environment variables still override config settings
  • ✅ Existing users see no behavior changes
  • ✅ Config file creation and editing workflow

Migration Strategy

Immediate (This PR)

  • ✅ Configuration file support is optional - existing setups work unchanged
  • ✅ Environment variables take precedence over config files
  • ✅ No breaking changes to existing functionality

Future Considerations

  • Documentation updates can gradually showcase config file examples
  • Future features can include config file validation
  • Potential GUI tools could generate/edit config files

Documentation Updates

README.md Changes

  • Added comprehensive "Configuration" section with examples
  • Documented network access setup using config files
  • Included cross-platform config file locations
  • Maintained all existing environment variable documentation

CLI Help

  • New ollama config subcommands with detailed help text
  • Examples showing both env var and config file approaches

Backward Compatibility

Guaranteed Compatibility

  • ✅ All existing environment variable usage continues working
  • ✅ No changes to default behavior when no config file exists
  • ✅ No performance impact for users not using config files
  • ✅ All existing scripts and automation continue working

Migration Path

Users can gradually adopt config files:

  1. Continue using environment variables (no changes needed)
  2. Run ollama config init to create example config
  3. Gradually move settings from env vars to config file
  4. Remove environment variables when ready (optional)

Example Config File Output

Running ollama config init creates:

# Ollama Configuration File
# This is an example configuration file. Uncomment and modify values as needed.

[server]
# Network binding address (default: "127.0.0.1:11434")
host = "127.0.0.1:11434"
# Allowed CORS origins (comma-separated)
origins = ["http://localhost:3000"]

[models]
# Custom models directory path
path = "/path/to/models"
# How long to keep models loaded in memory (default: "5m")
keep_alive = "5m"
# Maximum number of models to keep loaded (default: 0 = unlimited)
max_loaded_models = 3
# Maximum number of queued requests (default: 512)
max_queue = 512

[performance]
# Number of parallel model requests (default: 0 = auto)
num_parallel = 4
# GPU memory overhead in bytes (default: 0)
gpu_overhead = 0
# Enable flash attention (default: false)
flash_attention = false
# KV cache type: "f16" or "q4_0" (default: "f16")
kv_cache_type = "f16"

[logging]
# Enable debug logging (default: false)
debug = false

Success Metrics

This PR successfully addresses the original network binding issue:

Before: Complex network setup

# Windows users need to:
# 1. Open System Properties
# 2. Go to Environment Variables
# 3. Add OLLAMA_HOST=0.0.0.0:11434
# 4. Restart Ollama

After: Simple one-time setup

ollama config init
# Edit config.toml: host = "0.0.0.0:11434"
# Restart Ollama - works on all platforms

Related Issues

Addresses:

  • Network binding configuration complexity
  • Cross-platform configuration management
  • User onboarding friction
  • Configuration persistence and sharing

Dependencies

  • Added: github.com/BurntSushi/toml for TOML parsing
  • Added: golang.org/x/exp/slog for structured logging (already in use)

This implementation provides a foundation for improved Ollama configuration management while maintaining 100% backward compatibility and significantly improving the user experience for network configuration.
