During our Connect(); 2017 event this year we presented beautiful app demos using Xamarin.
We are happy to announce the release of SmartHotel360. This release intends to share a simplified version of SmartHotel360 reference sample apps used at Connect(); 2017 Keynotes. If you missed it, you can watch Scott Guthrie’s Keynote: Journey to the Intelligent Cloud in Channel 9.
For this reference app scenario, we built several consumer and line-of-business apps and an Azure backend. You can find all SmartHotel360 repos in the following locations:
Note: This document is about SmartHotel360 Azure Backend Services and Architecture
Welcome to the SmartHotel360 Backend repository. Here you'll find everything you need to run the backend services locally and/or deploy them in a Azure environment.
SmartHotel360 uses a microservice oriented architecture implemented using Docker containers. There are various services developed in different technologies: .NET Core 2, Java, and Node.js. These services use different data stores like PostgreSQL and SQL Server.
In production all these microservices run in a Kubernetes cluster, powered by Azure Container Service (ACS or AKS).
All of the back-end systems run inside of Docker containers. To build locally and see how things work the only requirement is that you install Docker.
During the installation phase you will notice errors if you haven't set your Docker configuration to use 4 GB of memory. Changing this is simple within the Docker configuration dialog. Just set the memory higher and restart Docker.
Clone this repository using your favorite Git client or by using the command:
git clone https://github.com/Microsoft/SmartHotel360-Azure-backend.git
Go to /src folder and type:
docker-compose build
After some minutes you'll have all Docker images created on your computer. Following images will be created (type docker images to see all images you have in your system):
smarthotels/suggestionssmarthotels/notificationssmarthotels/reviewssmarthotels/hotelssmarthotels/taskssmarthotels/discountssmarthotels/profilessmarthotels/configuration
All microservices can be run locally using Docker Compose. Starting all of the microservice images is a simple 3-step process.
PostgreSQL and SQL Server databases are stored in Docker containers. These containers should be started first so the databases are on-line when the application logic containers start up. Start the data stores first by typing:
docker-compose up sql-data reviews-data tasks-data
Wait for those containers to be initialized; you'll know they're ready once the console output stops appearing for longer than a minute. The screen shot below demonstrates the data store containiners' setup being complete and with them in a ready state.
Once the data stores are running, the microservices can be started. Open a new terminal window and execute a second call to docker-compose, this time with no images specified.
Note: It is important that you open a new terminal window and leave the first one running. Killing the terminal process with a
Ctrl-Cwill stop all of the data containers.
docker-compose up
This will start all the remaining containers. Once the containers are online the terminal should stop updating for a few seconds. The terminal screen shot below demonstrates what the terminal should look like once all the microservice containers are running.
Once the containers are started using the docker-compose up commands, their running state can be verified by executing this command:
docker ps
The terminal window will show all of the containers running. Take note of the ports that have been set for each of the microservice containers.
Each of these ports redirects to port 80 within the container image. Most of these microservices expose an Open API Specification (formerly known as Swagger) endpoint that describes the back-end REST APIs. To verify the APIs are up and running, use any of the ports in this list to browse the API description page for each of the microservices.
Note: not all of these URLs will result with a Swagger-UI test page, but they all should resolve once the microservices are all running.
