NEO Blockchain Quick Start Guide for .NET Developers

NEO Blockchain C# Developers Center of Excellence

The neo-csharpcoe project is an "umbrella" project for several initiatives related to providing tools and libraries (code), frameworks, how-to documentation, and best practices for enterprise application development using .NET/C#, C#.NEO and the NEO Blockchain software platform.

The neo-csharpcoe is an independent, free, open source project that is 100% community-supported by people like yourself through your contributions of time, energy, passion, promotion, and donations.

Activity 6 - Download, install, and test Docker platform

Purpose

The purpose of this activity is to download, install, and test the Docker container platform to in turn support the running of a local NEO private network (NEO privatenet).

Goals, Non-Goals and Assumptions

  • Ensure you have a working and properly configured set of NEO developer tools for creating and building smart contracts in Visual Studio with the C# programming language

Principles

  • Provide reliable documentation: timely, accurate, visual, and complete
  • Save as much of a person's time as possible
  • Use open source software whenever possible

Drivers

  • Need in the NEO .NET developer community to have concise and easy-to-follow documentation to enable people to get up to speed developing NEO smart contracts in as short a time as possible

Download and install the Docker platform

  1. Download the Docker for Windows (Stable version) installer from the Docker for Windows download site (https://docs.docker.com/docker-for-windows/install/)

    Docker for Windows download site: Stable version

    Figure 6.1. Docker for Windows download site: Stable version

  2. In your Downloads folder, double click on the Docker for Windows Installer.exe executable.

  3. The installation will start.

  5. After you login in to your computer, Docker will start. If the Docker notification doesn't appear, you can double-clock the Docker for Windows icon on the desktop.

    NOTE: The Docker "whale" icon that is display on the right-side of the Windows Taskbar.

Test the Docker platform

  1. In Windows Task Manager, you should see the Docker processes running

    Windows Task Manager: Docker Processes

    Figure 6.5. Windows Task Manager: Docker Processes

  2. In the Hyper-V Manager, you should see the MobyLinuxVM is installed and running.

    Hyper-V Manager: MobyLinuxVM Virtual Machine is Running

    Figure 6.6. Hyper-V Manager: MobyLinuxVM Virtual Machine is Running

  3. NOTE: If you are not running a valid version of Windows 10 or do not have the Hyper-V service installed properly, Docker may display a message similar to this one. Consult the Docker for Windows web site for more assistance.

    Potential Docker for Windows Issues

  4. Test Docker itself by starting Windows Powershell. From the Windows start menu, type "powershell". Select the Windows Powershell app from the list.

    Docker Basic Testing

    Figure 6.8. Docker Basic Testing

  5. In the Powershell console, enter docker run hello-world (and press Enter).

    Docker Run Hello-World

    Figure 6.9. Docker Run Hello-World

  6. The installation and testing of the Docker container platform is complete.

The tasks for this activity are complete. Proceed to Activity 7 - Download, install and test NEO privatenet Docker container.
