  1. To get started with ABP.IO microservices for your stack, use the official Microservice Startup Template. Download it with the ABP CLI:

  abp new Acme.BookStore -t microservice -u angular --database-provider postgresql
  

  This template includes .NET 8, Angular, PostgreSQL, Redis, and Docker support.

  2. The template provides sample Dockerfiles and a docker-compose.yml for all services (API Gateway, IdentityServer, microservices, Angular UI, PostgreSQL, Redis). After generating the solution, check the /docker folder and root docker-compose.yml. You can run all services with:

  docker compose up --build
  

  Make sure your docker-compose.yml exposes ports for API Gateway, IdentityServer, and Angular UI (e.g., 44300, 44301, 4200).

  3. Environment variables and connection strings are managed in docker-compose.override.yml and each service’s Dockerfile. For PostgreSQL and Redis, use service names as hostnames (e.g., Host=postgres; for PostgreSQL, Configuration=redis:6379 for Redis). ABP microservice templates use environment variables like ConnectionStrings__Default and Redis__Configuration for configuration. Example:

  environment:
    - ConnectionStrings__Default=Host=postgres;Port=5432;Database=abp;User Id=postgres;Password=yourpassword
    - Redis__Configuration=redis:6379
  

  All containers are on the same Docker network, so use service names (not localhost) for inter-service communication.

  4. Best practices:
     • Use the provided template and Docker Compose files as a base.
     • Always use Docker service names for connection strings.
     • Expose only necessary ports to your host.
     • For WSL2, access services via localhost:<exposed-port>.
     • Use .env files for secrets and environment-specific overrides.
     • For development, you can mount code as volumes for hot reload.

  If you have issues accessing services on localhost, ensure ports are published in docker-compose.yml and not blocked by firewalls. For WSL2, Docker’s networking is compatible with localhost access.
