![Define the Image for ASP.NET
Add a „Dockerfile“ to the project next to the project.json:
FROM microsoft/aspnet:latest
COPY . /app
WORKDIR /app
RUN ["dnu", "restore"]
EXPOSE 5001
ENTRYPOINT ["dnx", "kestrel"]](https://image.slidesharecdn.com/asp-150930163052-lva1-app6892/85/ASP-NET-5-auf-Raspberry-PI-docker-39-320.jpg)

ASP.NET 5 auf Raspberry PI & docker
1. The document discusses running ASP.NET 5 applications on a Raspberry Pi 2 and using Docker. 2. It provides steps for installing .NET Core, ASP.NET 5, and other prerequisites on the Raspberry Pi, and includes examples of building and running a simple ASP.NET app. 3. It also covers using Docker to build an image for an ASP.NET app, including defining a Dockerfile and building/running the image to host the app in a container.

- 19. Possible IDEs • Workingon the PI • vi Startup.cs • Nano Startup.cs • Working on Windows • Visual Studio • Visual Studio Code
- 20. Using Git • Transferfiles with Git • Git is easy to use • Git is integrated in Raspian • Git is integrated in Visual Studio 2015
- 21. Setup a Gitworkspace on Windows $ git init $ git add –all $ git commit -m „initial commit“ Push initially: $ git add origin https://github.org/juergengutsch/... $ git push -u origin master Push the latest changes: $ git push
- 22. Setup a Gitworkspace on the PI Setup a the IDE on the PI $ mkdir ~/projects/dnc15 & cd ~/projects/dnc15 Initial clone $ git clone https://github.org/juergengutsch/... Get the latest changes $ git pull
- 23. Setup the firstASP.NET 5 App for Kestrel • Add Dependencies: • "Microsoft.AspNet.Hosting": "1.0.0-beta7" • "Microsoft.AspNet.Server.Kestrel": "1.0.0-beta7” • Add Command: • "kestrel": "Microsoft.AspNet.Hosting --server crosoft.AspNet.Server.Kestrel -- server.urls http://localhost:5001"
- 24. Start the sampleweb Prepare the Start $ cd ~/projects/dnc15/Sensors/src/Sensors $ dnvm install latest $ dnu restore Starting the web server $ dnx kestrel
- 25. About the GPIOs Generalpurpose input/output • GPIO numbering vs. physical/pin numbering • 2 x output 5V • 2 x output 3.3V • 8 x ground • 26 x GPIO • (2x ID EEPROM)
- 26.
- 27. Working with theGPIOs • Calling the Raspian native API to connect the GPIOs • Using existing C# libraries to access the pins: • Raspberry.System • https://github.com/raspberry-sharp/raspberry-sharp • Raspberry.IO.GeneralPurpose • https://github.com/raspberry-sharp/raspberry-sharp-io • RPI.GPIO • https://github.com/fatihboy/RPI.GPIO
- 28. Good to know:Be carefully • Read carefully the GPIO specification • Wrong connected pins can kill the sensor or the PI • Read carefully the sensor specification • Be carefully with external power
- 29. Raspberry.System Getting common informationabout the PI:
- 30. Raspberry.IO.GeneralPurpose • Includes driversto access the GPIO Pins • Includes Pin connections • Includes conversions between pin numberings • ConnectorPin: Pin using physical pin numbers • ProcessorPin: Pin using GPIO pin numbering • Includes methods to work with the pins
- 31.
- 32. Good to know:Cheat with node.js • node.js is pretty cool on the PI • It‘s easy to write • It runs fast • many GPIO examples written in Javascript • node.js is a pretty awesome tool to tryout things, you want to implement with C#
- 33.
- 34. Docker • Lightweight Virtualization •Based on Linux Hosts (Windows is coming soon) • Use of VirtualBox to run the Linux Host on Windows • Machine = the Host • Image = Configuration • Container = a running image
- 35. Docker on Windows •Installing boot2docker (deprecated) or Docker Toolbox • Preparing a bash to work with Docker • Setup the environment variables (HOME and PATH) • Configure the bash using git-bash
- 36. Docker Machines List allavailable machines: $ docker-machine ls Create a new machine $ docker-mashine create testmachine Get the IP address or the config of the machine $ docker-mashine ip testmachine $ docker-machine config testmachine Start a machine $ docker-machine start testmachine
- 37. Docker Images List allavailable images $ docker images Get an image from the Docker Hub $ docker pull hello-world Starts and run an image (pulls the image if needed) $ docker run hello-world
- 38. Prepare ASP.NET fordocker • Create a new ASP.NET Project • Add the web server Kestrel to the commands: NuGet Packages: "Microsoft.AspNet.Hosting": "1.0.0-beta7", "Microsoft.AspNet.Server.Kestrel": "1.0.0-beta7“ Command: "kestrel": "Microsoft.AspNet.Hosting --server Microsoft.AspNet.Server.Kestrel --server.urls http://localhost:5001"
- 39. Define the Imagefor ASP.NET Add a „Dockerfile“ to the project next to the project.json: FROM microsoft/aspnet:latest COPY . /app WORKDIR /app RUN ["dnu", "restore"] EXPOSE 5001 ENTRYPOINT ["dnx", "kestrel"]
- 40. Build and runthe Image • Move to the project folder using the bash • Building the image: $ docker build -t guj/aspnet5 . • Check whether the image is registerd: $ Docker images • Running the image: $ docker run -i -t -p 5001:5001 guj/aspnet5
- 41. Calling the ASP.NETWeb • Call http://<machines ip>:5001/
- 42. Passing environment variables •Pass any argument as environment variable with docker run: $ docker run VARNAME1=OneValue VARNAME2=AnotherValue • Running the web in production mode: $ docker run -i -t -p 5001:5001 guj/aspnet5 ASPNET_ENV=Production • Running the web in staging mode: $ docker run -i -t -p 5001:5001 guj/aspnet5 ASPNET_ENV=Staging • Running the web in development mode: $ docker run -i -t -p 5001:5001 guj/aspnet5 ASPNET_ENV=Development
- 43. Why using Docker? •Fast and lightweight virtualisation • Composing infrastructure for microservice applications • Fast created on the dev machines • Easily distributed images to other devs • Fast and easy deployed to production machines
