Environment Variables

Nexus OS reads several environment variables for configuration that shouldn't be stored in files.

Core Variables

Variable	Description	Default
`NEXUS_HOME`	Project directory	Current directory
`NEXUS_DB_PATH`	Database file path	`data/nexus.db`
`NEXUS_LOG_LEVEL`	Log verbosity	`info`
`NEXUS_CONFIG`	Config file path	`nexus.config.yaml`

Cloudflare Edge

Variable	Description
`CF_ACCOUNT_ID`	Cloudflare account ID
`CF_API_TOKEN`	Cloudflare API token

AXIS Trust

Variable	Description
`AXIS_API_KEY`	AXIS Trust API key
`AXIS_API_URL`	AXIS API endpoint

Usage

# Set for current session
export NEXUS_LOG_LEVEL=debug
export CF_API_TOKEN=your-token-here

# Or inline with command
NEXUS_LOG_LEVEL=debug naos status

.env File

Nexus OS reads .env files in the project root:

# .env
NEXUS_LOG_LEVEL=debug
CF_ACCOUNT_ID=abc123
CF_API_TOKEN=your-token
AXIS_API_KEY=your-key

Security: Never commit .env files to version control. Add .env to your .gitignore.
