description: My automation project
version: 1.0.0

# Variables
vars:
  DATABASE_URL: postgresql://localhost/myapp
  API_ENDPOINT: https://api.example.com
  DEBUG: false

# Execution targets
targets:
  # Default settings inherited by all targets
  defaults:
    ssh:
      port: 22
      keepAlive: true
      keepAliveInterval: 30000
    docker:
      workdir: /app
      tty: true
    kubernetes:
      namespace: default

  # SSH hosts

Custom Parameters​

Beyond managed configuration sections, you can add custom parameters:

# Custom application configuration
myapp:
  database:
    pool_size: 10
    timeout: 30000
  cache:
    enabled: true
    ttl: 3600
    
# Custom deployment settings
deployment:
  environments:
    - staging
    - production
  rollback_limit: 5

Managing Custom Parameters​

# List custom parameters
xec config custom list

# Set custom parameter
xec config custom set myapp.database.pool_size 20

# Get custom parameter  
xec config custom get myapp.cache.ttl

# Delete custom parameter
xec config custom delete deployment.rollback_limit

# Export custom parameters
xec config custom export custom-config.yaml

Configuration Doctor​

The doctor command performs health checks and improvements:

xec config doctor

Doctor operations:

  • Ensures basic project information (name, description)
  • Adds default configurations for all target types
  • Creates standard command defaults
  • Validates configuration structure
  • Reports recommendations

With --defaults flag:

  • Writes all possible default values to configuration
  • Shows complete configuration schema
  • Useful for understanding all available options

Sample doctor output:

🏥 Running configuration doctor...

Doctor made the following improvements:
  ✅ Set project name
  ✅ Added SSH defaults
  ✅ Added Docker defaults  
  ✅ Added Kubernetes defaults
  ✅ Added exec command defaults
  ✅ Added logs command defaults

✅ Configuration is healthy! No changes needed.

Configuration Validation​

The validate command checks configuration integrity:

xec config validate

Validation checks:

  • Syntax: YAML parsing and structure
  • Required fields: Essential configuration elements
  • References: Variable and secret references
  • Target configuration: Connection parameters
  • Task definitions: Step and parameter validation
  • Type constraints: Data type validation

Sample validation output:

Validating configuration...

Configuration has errors:
  ❌ SSH host 'production': missing 'host' field
  ❌ Task 'deploy', step 2: must have either 'command', 'script', or 'task'

Configuration warnings:
  ⚠️  SSH host 'production': no authentication method specified
  ⚠️  Variable 'OLD_API_URL': unused variable
  
✅ Configuration is valid

File Operations​

Configuration File Location​

Configuration is stored in .xec/config.yaml in the project root:

my-project/
├── .xec/
│   ├── config.yaml      # Main configuration file
│   ├── scripts/         # Custom scripts
│   └── commands/        # Custom commands
└── ...

Configuration Format​

Xec uses YAML for human-readable configuration:

# Comments are preserved
name: my-project  # Project name

# Hierarchical structure
targets:
  hosts:
    production:
      host: prod.example.com
      port: 22

Backup and Recovery​

# Manual backup
cp .xec/config.yaml .xec/config.yaml.backup

# Export configuration
xec config list --json > config-backup.json

# Restore from backup
cp .xec/config.yaml.backup .xec/config.yaml

Integration with Other Commands​

Scripts and Tasks​

Configuration values are available in scripts:

// Access configuration in scripts
const config = xec.config;
console.log(`Project: ${config.name}`);
console.log(`Database: ${config.vars.DATABASE_URL}`);

// Access resolved variables
const dbUrl = await vars.get('DATABASE_URL');
const apiKey = await secrets.get('API_KEY');

Command Execution​

Configuration affects command behavior:

# SSH command uses host configuration
xec on production "ls -la"

# Docker command uses container configuration  
xec in app "npm install"

# Logs command uses configured defaults
xec logs app  # Uses defaults.logs.tail setting

Profile Support​

Configuration can vary by profile:

# Set configuration for specific profile
xec config set vars.API_URL "https://staging-api.example.com" -p staging

# View configuration with profile
xec config view -p production

# Validate profile-specific configuration
xec config validate -p staging

Security Considerations​

Secret Management​

  • Never store secrets in configuration
  • Use secret references: ${secret:KEY_NAME}
  • Manage secrets separately: Use xec secrets command
# Good: Secret reference
vars:
  DATABASE_PASSWORD: "${secret:DB_PASSWORD}"
  
# Bad: Plain text secret
vars:
  DATABASE_PASSWORD: "secret123"

Permission Management​

# Secure configuration directory
chmod 700 .xec/
chmod 600 .xec/config.yaml

Access Control​

  • Configuration files should not be world-readable
  • Use .gitignore to exclude sensitive configurations
  • Consider separate configuration for different environments

Troubleshooting​

Common Issues​

"Configuration file not found":

# Initialize new configuration
xec config doctor

"Invalid YAML syntax":

# Validate and fix syntax
xec config validate

# View problematic lines
cat -n .xec/config.yaml

"Target connection failed":

# Test target connectivity
xec config targets test production

# Validate target configuration
xec config validate

Debug Mode​

# Enable debug logging
export XEC_DEBUG=config
xec config list
  • secrets - Manage secrets referenced in configuration
  • inspect - Analyze and validate configuration
  • run - Execute tasks defined in configuration
  • new - Create new configuration elements

Exit Codes​

  • 0 - Success
  • 1 - General error
  • 2 - Invalid arguments
  • 3 - Configuration not found
  • 4 - Validation failed
  • 5 - Permission error
