In this example, you will use a sample application that has a split frontend and backend. This app stack has the following configuration\n\nAll requests to /api to go to the API service All other requests to localhost go to the frontend client Since the app uses MySQL, db.localhost should provide phpMyAdmin to make it easy to access the database during development\n\nArchitecture diagram showing Traefik routing requests to other containers based on the path of the request\n\nThe application can be accessed on GitHub at dockersamples/easy-http-routing-with-traefik.\n\nIn the compose.yaml file, Traefik is using the following configuration\n\nBounded code example (external data; do not execute automatically):\n```yaml\n   services:\n     proxy:\n       image: dhi.io/traefik:3.6.2\n       command: --providers.docker\n       ports:\n         - 80:80\n       volumes:\n         - /var/run/docker.sock:/var/run/docker.sock\n```\n\nBounded code example (external data; do not execute automatically):\n```yaml\n   services:\n     proxy:\n       image: traefik:v3.6.2\n       command: --providers.docker\n       ports:\n         - 80:80\n       volumes:\n         - /var/run/docker.sock:/var/run/docker.sock\n```\n\nNote that this is essentially the same configuration as used earlier, but now in a Compose syntax.\n\nThe client service has the following configuration, which will start the container and provide it with the labels to receive requests at localhost.\n\nDocker Hardened Images (DHI) for Nginx are available on Nginx DHI image.\n\nIf you haven't authenticated yet, first run\n\nBounded code example (external data; do not execute automatically):\n```bash\n   $ docker login dhi.io\n```\n\nYou can use it as your base image as shown following\n\nBounded code example (external data; do not execute automatically):\n```yaml\n   services:\n     # …\n     client:\n       image: dhi.io/nginx:1.29.3-alpine3.21\n       volumes:\n         - \"./client:/usr/share/nginx/html\"\n       labels:\n         traefik.http.routers.client.rule: \"Host(`localhost`)\"\n```\n\nBounded code example (external data; do not execute automatically):\n```yaml\n   services:\n     # …\n     client:\n       image: nginx:1.29.3-alpine3.22\n       volumes:\n         - \"./client:/usr/share/nginx/html\"\n       labels:\n         traefik.http.routers.client.rule: \"Host(`localhost`)\"\n``` …\n\nAttribution: Adapted from Docker Documentation under Apache-2.0.
