It generates HTML, CSS, and JavaScript into an out directory that can be served by any static host or CDN—no Node.js server at runtime. Use this when you don't need server-side rendering or API routes. For details, see the Next.js output configuration documentation.\n\nConfigure Next.js — Open next.config.ts in your project root and add the following code\n\nBounded code example (external data; do not execute automatically):\n```ts\nimport type { NextConfig } from \"next\";\n\nconst nextConfig: NextConfig = {\n  output: \"export\",\n  trailingSlash: true,\n  images: {\n    unoptimized: true,\n  },\n};\n\nexport default nextConfig;\n```\n\nChoose either a Docker Hardened Image or the Docker Official Image, then create a Dockerfile using the content from the selected tab below.\n\nDocker Hardened Images (DHIs) are available for Node.js and Nginx in the Docker Hardened Images catalog. For more information, see the DHI quickstart guide.\n\nSign in to the DHI registry\n\nBounded code example (external data; do not execute automatically):\n```console\n   $ docker login dhi.io\n```\n\nPull the Node.js DHI (check the catalog for available versions)\n\nBounded code example (external data; do not execute automatically):\n```console\n   $ docker pull dhi.io/node:24-alpine3.22-dev\n```\n\nPull the Nginx DHI (check the catalog for available versions)\n\nBounded code example (external data; do not execute automatically):\n```console\n   $ docker pull dhi.io/nginx:1.28.0-alpine3.21-dev\n```\n\nCreate a file named Dockerfile with the following contents. The FROM instructions use Docker Hardened Images: dhi.io/node:24-alpine3.22-dev and dhi.io/nginx:1.28.0-alpine3.21-dev. Check the Docker Hardened Images catalog for the latest versions and update the image tags as needed for security and compatibility.\n\nBounded code example (external data; do not execute automatically): …\n\nAttribution: Adapted from Docker Documentation under Apache-2.0.
