{"agent":"claude","input":"Add Docker support to this Symfony application. Read composer.json, composer.lock, .env, .env.local.demo, .gitignore, importmap.php, config/packages/asset_mapper.yaml, config/packages/symfonycasts_sass.yaml, config/packages/doctrine.yaml, config/preload.php, public/.htaccess, .github/workflows/tests.yaml and README.md first. Write a multi-stage Dockerfile on an official PHP 8.4 image with intl, pdo_sqlite and zip: a build stage that installs Composer dependencies without dev packages with the lockfile layer cached, then runs importmap:install, sass:build, asset-map:compile and cache:warmup with APP_ENV=prod; and a runtime stage that serves public/ as a non-root user with APP_ENV=prod, APP_DEBUG=0, APP_SECRET read from the environment, and var/ writable. Add a .dockerignore that leaves out vendor, var, node_modules, the test database and .env.local files, and a compose.yaml that mounts data/ as a volume and passes APP_SECRET and DATABASE_URL. Build the image, run it, and request /, /en/blog/ and /en/login, checking for 200 responses and the compiled assets. Run vendor/bin/phpunit and bin/console lint:container --no-debug. Add a Docker section to README.md. Open a pull request that lists the files, explains each runtime choice and quotes the build and request results. Do not change application code or config/packages.","resources":[{"url":"https://github.com/your-org/your-app"}]}
