A single node server.js can serve the app, which is ideal for Docker and supports server-side rendering, API routes, and incremental static regeneration. For details, see the Next.js output configuration documentation (including the \"standalone\" option).\n\nThe container runs the Next.js server with Node.js on port 3000.\n\nConfigure Next.js — Open or create next.config.ts in your project root\n\nBounded code example (external data; do not execute automatically):\n```ts\nimport type { NextConfig } from \"next\";\n\nconst nextConfig: NextConfig = {\n  output: \"standalone\",\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 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\nCreate a file named Dockerfile with the following contents. The FROM instructions use dhi.io/node:24-alpine3.22-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.
