Create Dockerignore

.dockerignore Generator

Generates optimized .dockerignore files for PHP projects, reducing build context size and improving build performance.

Generated Files

.dockerignore             # Optimized exclusion rules

Generation Instructions

1. Detect project type: Check for symfony.lock (Symfony), artisan (Laravel), or generic PHP
2. Analyze existing files: Read .gitignore, check CI/CD config, identify test/doc directories
3. Generate .dockerignore: Universal exclusions + framework-specific + proper ! negations

Build Context Impact

Validation Rules

1. Never exclude: composer.json, composer.lock, source code (src/, app/, config/, public/), migrations
2. Always exclude: .git, vendor/, tests, IDE files, local env files with secrets
3. Framework awareness: Symfony: exclude var/, keep config/, public/, templates/; Laravel: exclude storage/, keep config/, public/, resources/

Usage

Provide:

• Framework (Symfony/Laravel/generic PHP)
• Monorepo structure (yes/no)
• Custom exclusions (optional)

The generator will:

1. Create .dockerignore with universal exclusions
2. Add framework-specific exclusions
3. Add proper negation rules for required files
4. Optimize for minimal build context
