  To host multiple ABP applications (Web Public, Blazor Admin, API, AuthServer) on a single Azure App Service using Web App for Containers with Docker Compose, and expose them under different paths on the same domain, you need to use a reverse proxy container (such as Nginx or Traefik) as the entry point. This proxy will route requests to the correct internal service based on the URL path.

  Step-by-Step Solution

  1. Prepare Docker Images for Each App

     • Build/publish Docker images for each ABP application: Web Public, Blazor Admin, API, and AuthServer.
     • Push these images to a container registry (e.g., Azure Container Registry or Docker Hub).

  2. Create a Reverse Proxy Configuration

     • Use Nginx (or Traefik) as a reverse proxy to route traffic based on the URL path.
     • Example Nginx configuration (nginx.conf):

  server {
           listen 80;
           server_name www.example.com;
  
           location / {
               proxy_pass http://webpublic:80;
           }
           location /admin/ {
               proxy_pass http://blazoradmin:80/;
               rewrite ^/admin(/.*)$ $1 break;
           }
           location /api/ {
               proxy_pass http://api:80/;
               rewrite ^/api(/.*)$ $1 break;
           }
           location /auth/ {
               proxy_pass http://authserver:80/;
               rewrite ^/auth(/.*)$ $1 break;
           }
       }
  

  • This configuration assumes your internal Docker services are named webpublic, blazoradmin, api, and authserver.

  3. Create a docker-compose.yml File
     • Example:

  version: '3.8'
       services:
         nginx:
           image: nginx:latest
           ports:
             - "80:80"
           volumes:
             - ./nginx.conf:/etc/nginx/conf.d/default.conf:ro
           depends_on:
             - webpublic
             - blazoradmin
             - api
             - authserver
  
         webpublic:
           image: <your-registry>/webpublic:latest
           environment:
             # Set environment variables as needed
           # ...
  
         blazoradmin:
           image: <your-registry>/blazoradmin:latest
           environment:
             # ...
           # ...
  
         api:
           image: <your-registry>/api:latest
           environment:
             # ...
           # ...
  
         authserver:
           image: <your-registry>/authserver:latest
           environment:
             # ...
           # ...
  

  4. Deploy to Azure App Service for Containers

     • Zip your docker-compose.yml and nginx.conf and deploy to your Azure App Service configured for multi-container (Docker Compose) deployment.
     • Ensure your App Service is set to use Linux and supports Docker Compose.

  5. HTTPS Configuration

     • Azure App Service provides a built-in SSL certificate for your domain. All traffic will go through the Nginx container, which will receive HTTPS traffic from Azure's front end and forward it to your internal services over HTTP.

  6. ABP Application Configuration

     • Set the App:SelfUrl and other relevant URLs in each app to match the public paths (e.g., https://www.example.com/admin for Blazor Admin).
     • Update CORS and redirect URIs to match the new paths.

  Notes

  • All endpoints will share the same domain and SSL certificate.
  • Path-based routing is handled by the reverse proxy.
  • You do not need multiple App Services or subdomains.

  Example Reference

  • Official ABP Docker Compose deployment guide:
    • https://abp.io/docs/latest/solution-templates/layered-web-application/deployment/deployment-docker-compose

  This approach is fully supported and aligns with ABP and Azure best practices for containerized multi-app hosting.

  Hi

  I have followed the ABP documentation for Docker Compose deployment: https://abp.io/docs/latest/solution-templates/layered-web-application/deployment/deployment-docker-compose?UI=Blazor&DB=EF&Tiered=Yes I have successfully deployed a single application to an Azure App Service for Containers. I want to deploy multiple applications in a single Azure App Service using Docker Compose. Could you please guide me on how to host multiple applications in a single azure App Service using docker compose?
