The dotnet-bot sample demonstrates "hello world" type usage of .NET Core. It displays dotnet-bot, the open source mascot for .NET Core projects. This sample is very similar to the Docker whalesay sample.

You will exercise the following topics in this sample.

• Building and running a .NET Core application.
• Creating a Docker image for a .NET Core application.
• Running a .NET Core application in container.

Follow these steps to try out this sample. The instructions are intended to be Operating System agnostic, unless called out.

Preparing your Environment

1. Install the .NET Core SDK for your operating system.
2. Git clone this repository or otherwise copy this sample to your machine: git clone https://github.com/dotnet/core/
3. Navigate to the sample on your machine at the command prompt or terminal.

Run the application

4. Restore dependencies: dotnet restore
5. Run application: dotnet run
6. Alternatively, you can build and directly run your application with the following two commands:
   • dotnet build
   • dotnet bin/Debug/netcoreapp1.0/dotnetbot.dll
7. You can also try passing input to the sample to get the dotnet-bot to say something: dotnet run dotnet-bot is a great teacher

Dockerize the application

The Docker instructions are OS agnostic, however, the Dockerfile used relies on a Linux image.

8. Install the Docker tools for your operating system.
9. Build a Docker container, as specified by the Dockerfile: docker build -t dotnetbot .
10. Run the application in the container: docker run dotnetbot Hello .NET Core from Docker
