Micro Cafe

Sample code to show microservices using NET, in the context of a cafe

Code should be used for inspiration, not duplication.

The code here is currently a work in progress. The admin microservice is functional, but the cashier and barista services are not finished and don't compile. I'm happy to take a pull request :-)

##Slides

If you're interested in the slides related to this code, they're on SlideShare

P.S. I'm hacking around with making a .NET Core, Dockerised version of this sample code as well. Stay tuned (or submit a pull request if you can't wait for it)

microcafe's Issues

Can i access API out side the network if i am using windows service hosting

please let me know can i access api inside or out side the network if i am using windows service hosting as i have hosted service on production server but not able to access it on my machine,please help me asap

Port to .NET Core

(replacing #3)
Now that VS2017 is RTM, it's time to move this to .NET core.

Also, given https://github.com/gautema/cqrslite is a framework based on the same fundamentals that this code uses we'll move across to that and make this code more about the services themselves and less about the plumbing.

Snapshotting with event store

In the domain services, to avoid long rebuilds of model state show how snapshotting can be used.

For the sample we might do snapshotting at every 5 events.

Rebuilding read models

Add mechanism for manually triggering read model rebuilds.

Cleanup cashier and barista services

Get them working to show cross-service comms working properly.

Run in linux docker containers

(Replaces #3)

Get things running in Linux containers. Very similar to #1

How to deploy code if using Micro Service Architecture like Microcafe

Hi,

Please help....

Discovery service

Even though it's not really needed because there's so few services, add a discovery service to show how it works.

Consul.io and Microphone, for example

Improve the UI

Make the UI more dashboard-y so we can show how different read models and domain services can be fronted by an API gateway, and how a single page can be rendered using data from different contexts.

Can I use Owin hosting to IIS instead of Self Hosting or Windows Service

Hi,

I have used owin hosting to IIS, it is taking too long to appendStream(i.e. eventStoreConnection.AppendToStreamAsync) into EventStore.Please help me asap

.NET Core, Linux and Docker

Port code to .NET core, deploy to Linux based containers.
Use dockerised versions of RabbitMq and Redis as well

Problem running powershell scripts, such as

Hi,

Thanks ahead of time for any help. This is not a microcafe issue per se, but I'm new to powershell and receive the errors below when invoking the .ps1 scripts from a PS cmd line.

When running the Build-Microservices.ps1 (after invoking powershell via command line), received the following error message (which is probably due to the powershell setup on my machine):

Topshelf process not really quitting

Hi,

What could be done in order for the command window to close when the Topshelf service is disposed? I'm not able to find any information on that in the Topshelf documentation. Say, the "Admin.Service.exe" is running, I want to stop it, so I go to the window hosting it and press CTRL+C. This shuts down the service, but the executable is still running (e.g. I can see it in Task Manager). How can I avoid that?

Thanks! And great project, it gave me lots of insight on microservices in .Net.

Run services in windows containers (docker)

Instead of running the services as a number of self-hosted console apps, get them running in containers.

For this one, I want to target Windows Containers using nanoserver as the base image, running on Windows 10 (anniversary update required).
