Commands

nyl provides several commands for managing Kubernetes manifests:

Available Commands

Phase 1 (Current)

• new - Create new projects and components
• validate - Validate project configuration

Phase 2+ (Coming Soon)

• rendering-pipeline - Shared rendering pipeline used by render/diff/apply
• render - Render Kubernetes manifests
• diff - Show diff between rendered manifests and cluster state
• apply - Apply rendered manifests to the cluster

Global Options

--verbose / -v

Enable verbose logging for debugging.

nyl --verbose validate
nyl -v new project my-app

--color <COLOR>

Control when to use colored output. Accepts three values:

• auto (default) - Automatically detect if colors should be used based on TTY detection
• always - Always use colors, even when output is redirected to a file or pipe
• never - Never use colors

This applies to both:

• Colored output from commands (diffs, status indicators, etc.)
• Log messages from tracing (INFO, WARN, ERROR)

This flag is particularly useful when:

• Redirecting output to a file where ANSI color codes are not desired
• Working in environments where terminal color support is inconsistent
• Forcing colored output in CI/CD pipelines that support ANSI colors

# Disable colors when piping to a file
nyl --color never diff | tee output.txt

# Force colors in CI/CD
nyl --color always diff

# Auto-detect (default behavior)
nyl diff
