Programming Arduino with Visual Studio Code

Microsoft Visual Studio Code is a cross-platform, Node.js-based IDE (Integrated Development Environment). It’s been maturing into a really amazing development tool. It’s not really the tool itself as it’s all the amazing plugins or extensions that are being developed for it that are enable some really amazing functionality and development scenarios. One of these awesome extensions is the “Arduino for Visual Studio Code” extension. This extension adds the ability to program Arduino and Arduino-compatible devices using Visual Studio Code as an alternative to the Arduino IDE. Read More

Azure CLI 1.0 vs 2.0 Compared, Installation and Usage

The Azure CLI is the cross-platform, command-line tool for managing resources in Microsoft Azure. Microsoft recently released the Azure CLI 2.0 and the commands start with “az” instead of “azure” like Azure CLI 1.0. This article runs through the main differences between Azure CLI 1.0 and Azure CLI 2.0 to help you understand how to use each one.

Installation and Platform

When the Azure CLI 1.0 was first released it was call the X-Plat CLI, and offered a new cross-platform command-line tool to use for Azure automation tasks. It offered an alternative to the Azure PowerShell cmdlets that gave a command-line tool for use on macOS and Linux, in addition to Windows. In the early days it was built on top of the Azure Service Management API’s, and has since been migrated over to support the newer Azure Resource Management API’s.

The new Azure CLI 2.0 was built with Azure Resource Management (ARM) from the start. It was also built with the lessons learned from 1.0 in mind to make 2.0 a better cross-platform, command-line tool. The development platform and language used to build the Azure CLI 2.0 was changed, and the commands essentially changed a bit in the process. It’s really not an “in-place” migration, and requires you to understand a little more than to just install the new version.

The Azure CLI 1.0 was written with Node.js to achieve cross-platform capabilities, and the new Azure CLI 2.0 is written in Python to offer better cross-platform capabilities. Both are Open Source and available on Github.

Azure CLI 2.0 is written in Python, Azure CLI was written in JavaScript. Both are Open Source!

Here’s the platform differences between the 2 version of the Azure CLI along with links where you can find the Open Source repository for each:

Azure CLI 1.0

Azure CLI 2.0

Azure CLI Installation

Since the Azure CLI is cross-platform it can be installed on Windows, macOS, and Linux. This is true for both the Azure CLI 1.0 and Azure CLI 2.0. Since the Azure CLI 1.0 is written with Node.js, it will require Node.js to be installed on your machine. While the Azure CLI 2.0 is written in Python, and requires Python.

Azure CLI 1.0 Installation

Here’s commands to install Azure CLI 1.0 at the command-line using Node.js:

sudo npm install -g azure-cli

Use a Docker Container to run the Azure CLI 1.0:

docker run -it microsoft/azure-cli

You can also use an installer with Windows and macOS to install the Azure CLI 1.0 more easily as well. You can find the installers for the Azure CLI 1.0 on the Github repository.

Azure CLI 2.0 Installation

Here’s commands to install Azure CLI 2.0 on different platforms. Keep in mind that it does require Python.

Windows Command-Line

You can download the .MSI installer for Azure CLI 2.0 to install the Windows command-line support for Azure CLI.

Bash on Windows 10

The Ubuntu Bash on Windows 10 can be used to run the Azure CLI 2.0 while utilizing it’s full support for Bash and on a Windows 10 machine at the same time.

  1. First step, if you don’t have Bash on Windows installed (Ubuntu Bash on Windows 10, or the newer (coming soon) support for SUSE and Fedora on Windows 10 too!) then install it!
  2. Using Bash, modify your sources list:
    echo "deb [arch=amd64] https://packages.microsoft.com/repos/azure-cli/ wheezy main" | \
    sudo tee /etc/apt/sources.list.d/azure-cli.list
    

Run the following sudo commands to install the Azure CLI 2.0:

sudo apt-key adv --keyserver packages.microsoft.com --recv-keys 417A0893
sudo apt-get install apt-transport-https
sudo apt-get update && sudo apt-get install azure-cli

macOS and Linux
Here’s the installation command to install the Azure CLI 2.0 on macOS as well as Linux using Curl:


curl -L https://aka.ms/InstallAzureCli | bash

Additionally, you may need to restart your command-lim in order for some changes to take affect. You can do this with the following command:


exec -l $SHELL

Docker Container

You can also run the Azure CLI 2.0 in a Docker Container fairly easily. Here’s the “docker run” command to do this:


docker run azuresdk/azure-cli-python:<version>

apt-get on Linux

You can also use the following commands to install Azure CLI 2.0 on Linux using apt-get.

On 32-bit systems:


echo "deb https://packages.microsoft.com/repos/azure-cli/ wheezy main" | \
sudo tee /etc/apt/sources.list.d/azure-cli.list

On 64-bit systems:


echo "deb [arch=amd64] https://packages.microsoft.com/repos/azure-cli/ wheezy main" | \
sudo tee /etc/apt/sources.list.d/azure-cli.list

After you run the above 32-bit or 64-bit specific command, then you’ll need to run the following sudo commands as well:


sudo apt-key adv --keyserver packages.microsoft.com --recv-keys 417A0893
sudo apt-get install apt-transport-https
sudo apt-get update && sudo apt-get install azure-cli

There is some further documentation for installing the Azure CLI 2.0 available in the Azure Documentation site.

Getting Started with Azure CLI Commands

Both the Azure CLI 1.0 and 2.0 have very similar commands. However, the command start differently. With the Azure CLI 1.0 commands start with “azure” and with the Azure CLI 2.0 command start with “az”.

Before you can go about running Azure CLI commands, you need to first login to your Azure Subscription. Here are commands to do this in both Azure CLI versions:


# Azure CLI 1.0

azure login

#Azure CLI 2.0

az login

To get a full list of the available commands and full help information you can run the following command:


# Azure CLI 1.0

azure

# Azure CLI 2.0

az

Also, you can find the version of Azure CLI you have installed by using the following command:


# Azure CLI 1.0

azure --version

# Azure CLI 2.0

az --version

Azure CLI Command Examples

Here’s some example commands using both the Azure CLI 1.0 and Azure CLI 2.0. You can see that they aren’t really all that different outside of the trigger command of either “azure” or “az”.

Create New Azure Resource Group


# Azure CLI 1.0

azure group create --name MyGroup1 --location eastus

# Azure CLI 2.0

az group create --name MyGroup1 --location eastus

Create Azure App Service Plan


# Azure CLI 1.0

azure appserviceplan create --name MyPlan --resource-group MyGroup1 --location eastus --sku F1

# Azure CLI 2.0

az appservice plan create --name MyPlan --resource-group MyGroup1 --location eastus --sku F1

List All Azure Virtual Machines


# Azure CLI 1.0

OSS Spotlight: Swagger

There have been a few approaches to make sharing and consuming Web Services easier over the years. Many developers have worked with WSDL and SOAP services, as they were extremely popular in the early 2000’s and the beginnings of the .NET Framework. However, everything has moved on to being REST based and using JSON these days. This is a huge difference, and web service discoverability and sharing has needed to change in big ways as well. Swagger.io is a project that helps make RESTful APIs more easily sharable, discoverable, and self-documenting. Plus, Swagger is cross-platform and supports every popular programming language/framework.

Swagger is a powerful open source framework backed by a large ecosystem of tools that helps you design, build, document, and consume your RESTful APIs.

Tutorial: Create Minecraft Server in Azure on an Ubuntu VM

Setting up a Minecraft server generally takes a bit of work from installing the Operating System, installing Java, to setting up the Minecraft Server to run itself. This is all in addition to putting some kind of hardware together to run it, and if you do it at home it’s only available to players on your local Wifi / network. When you create a Minecraft Server in the cloud, such as Microsoft Azure, the entire setup is completely automated and the resulting Minecraft Server is available across the Internet to any players you want to invite to your server. Additionally, the cost of running the server is likely much lower than you might expect. In this article, we’ll run through the steps necessary to setup a Minecraft Server to run in Microsoft Azure. We’ll also discuss the cost implications of running a Minecraft Server in the cloud, along with some tips and tricks for keeping the cost as low as possible.

Whether you want to create a Minecraft Server just for yourself, your friends, or your own kids, this article will get you through the setup process and give you the knowledge you’ll need to host your very own Minecraft Server! Read More
