Getting Started

Make sure you have installed and configured docker in your environment. After that, you can run the below commands from the /src/ directory and get started with the eShopOnContainers immediately.

docker-compose build
docker-compose up

You should be able to browse different components of the application by using the below URLs :

Web Status : http://host.docker.internal:5107/
Web MVC :  http://host.docker.internal:5100/
Web SPA :  http://host.docker.internal:5104/

Note: If you are running this application in macOS then use docker.for.mac.localhost as DNS name in .env file and the above URLs instead of host.docker.internal.

Below are the other avenues to setup eShopOnContainers.

Basic scenario

The basic scenario can be run locally using docker-compose, and also deployed to a local Kubernetes cluster. Refer to these Wiki pages to Get Started:

• Visual Studio (F5 experience)
• Docker compose on windows
• Docker compose on macOS
• Local Kubernetes

Advanced scenario

The Advanced scenario can be run only in a Kubernetes cluster. Currently this scenario is the same as a basic scenario with the following differences:

• Deploy to AKS with a Service Mesh for resiliency

In the future more features will be implemented in the advanced scenario.

IMPORTANT NOTES!

You can use either the latest version of Visual Studio or simply Docker CLI and .NET CLI for Windows, Mac and Linux.

Note for Pull Requests (PRs): We accept pull request from the community. When doing it, please do it onto the DEV branch which is the consolidated work-in-progress branch. Do not request it onto master branch.

Updated for .NET Core 3.1 (LTS)

eShopOnContainers is updated to .NET Core 3.1 “wave” of technologies. Not just compilation but also new recommended code in EF Core, ASP.NET Core, and other new related versions with several significant changes.

See more details in the Release notes wiki page.

PLEASE Read our branch guide to know about our branching policy

DISCLAIMER

IMPORTANT: The current state of this sample application is BETA, because we are constantly evolving towards newly released technologies. Therefore, many areas could be improved and change significantly while refactoring the current code and implementing new features. Feedback with improvements and pull requests from the community will be highly appreciated and accepted.

Architecture overview

This reference application is cross-platform at the server and client side, thanks to .NET Core services capable of running on Linux or Windows containers depending on your Docker host, and to Xamarin for mobile apps running on Android, iOS or Windows/UWP plus any browser for the client web apps. The architecture proposes a microservice oriented architecture implementation with multiple autonomous microservices (each one owning its own data/db) and implementing different approaches within each microservice (simple CRUD vs. DDD/CQRS patterns) using Http as the communication protocol between the client apps and the microservices and supports asynchronous communication for data updates propagation across multiple services based on Integration Events and an Event Bus (a light message broker, to choose between RabbitMQ or Azure Service Bus, underneath) plus other features defined at the roadmap.

Related documentation and guidance

You can find the related reference Guide/eBook focusing on architecting and developing containerized and microservice based .NET Applications (download link available below) which explains in detail how to develop this kind of architectural style (microservices, Docker containers, Domain-Driven Design for certain microservices) plus other simpler architectural styles, like monolithic apps that can also live as Docker containers.

There are also additional eBooks focusing on Containers/Docker lifecycle (DevOps, CI/CD, etc.) with Microsoft Tools, already published plus an additional eBook focusing on Enterprise Apps Patterns with Xamarin.Forms. You can download them and start reviewing these Guides/eBooks here:
