Andrew Connell's Blog (Andrew Connell) - This nice post is the second of a series of three. It explains how to do every step but also why the author decided to do that.
Highlights from Git 2.23 ( Taylor Blau) - This was the first time I notice an update of git... It is very intriguing to see such a powerful tool evolving and see some experimental feature. It's a long post, but totally worth it.
Docker from the beginning — part III (Chris Noring) - Third of this docker series. I like how it is not only a happy path but the learning path with the fails and victories.
Extreme Ownership: How U.S. Navy SEALs Lead and Win (Jocko Willink, Leif Babin) - Very interesting book. Yes, it contains a lot of battle details, and first I was not sure, but then things "fall" all in place when you understand what the story was "demonstrating." It also contains more business focus examples. Everything is very clear, well explained in plain English.
For a project I just started, I need to create Azure resources from code. In fact, I want to create an Azure Container Instance. I already know how to create a container from Logic Apps and Azure CLI/PowerShell, but I was looking to create it inside an Azure Function. After a quick research online, I found the Azure Management Libraries for .NET (aka Fluent API) a project available on Github that do just that (and so much more)!
In this post, I will share with you how this library work and the result of my test.
The Goal
For this demo, I will create a .Net Core console application that creates an Azure Containter Instance (ACI). After it should be easy to take this code and migrate to an Azure Function or anywhere else.
The Console Application
Let's create a simple console application with the following command: dotnet new console -o AzFluentDemo cd AzFluentDemo dotnet add package microsoft.azure.management.fluent The last command will use the nuget package available online an add it to our solution. Now we need a service principal so our application could access the Azure subscription. A since way to create one is the use Azure CLI az ad sp create-for-rbac --sdk-auth > my.azureauth This will create an Active Directory (AD) Service Principal (SP) and write the content into the file my.azureauth. Perfect, now open the solution, for this kind of project, I like to use Visual Studio Code so code . will do the work for me. Replace the content of the Program.cs file by the following code.
using System;
using Microsoft.Azure.Management.Fluent;
using Microsoft.Azure.Management.ResourceManager.Fluent;
using Microsoft.Azure.Management.ResourceManager.Fluent.Core;
namespace AzFluentDemo
{
class Program
{
static void Main(string[] args)
{
string authFilePath = "/home/frank/Dev/AzFluentDemo/my.azureauth";
string resourceGroupName = "cloud5mins";
string containerGroupName = "frank-containers";
string containerImage = "microsoft/aci-helloworld";
// Set Context
IAzure azure = Azure.Authenticate(authFilePath).WithDefaultSubscription();
ISubscription sub;
sub = azure.GetCurrentSubscription();
Console.WriteLine($"Authenticated with subscription '{sub.DisplayName}' (ID: {sub.SubscriptionId})");
// Create ResoureGroup
azure.ResourceGroups.Define(resourceGroupName)
.WithRegion(Region.USEast)
.Create();
// Create Container instance
IResourceGroup resGroup = azure.ResourceGroups.GetByName(resourceGroupName);
Region azureRegion = resGroup.Region;
// Create the container group
var containerGroup = azure.ContainerGroups.Define(containerGroupName)
.WithRegion(azureRegion)
.WithExistingResourceGroup(resourceGroupName)
.WithLinux()
.WithPublicImageRegistryOnly()
.WithoutVolume()
.DefineContainerInstance(containerGroupName + "-1")
.WithImage(containerImage)
.WithExternalTcpPort(80)
.WithCpuCoreCount(1.0)
.WithMemorySizeInGB(1)
.Attach()
.WithDnsPrefix(containerGroupName)
.Create();
Console.WriteLine($"Soon Available at http://{containerGroup.Fqdn}");
}
}
}
In the first row, I declare a few constants. The path of the service principal created earlier, resource group name, the container group name, and the image I will use. For this demo aci-helloworld. Then we get access with the Azure.Authenticate. Once we got access, it's y easy and the intellisense is fantastic! I don't think I need to explain the rest of the code as it already self-explanatory.
Got an Error?
While running you main in contour an error message complaining about the namespace not being registered or something like that ( I'm sorry I did not note the error message). You only need to register it with the command:
az provider register --namespace Microsoft.ContainerInstance
It will take a few minutes. To see if it's done you can execute this command:
az provider show -n Microsoft.ContainerInstance --query "registrationState"
Wrap it up
And voila! If you do a dotnet run after a minute or two, you will have a new web application running inside a container available from http://frank=containers.eastus.azurecontainer.io. It's now very easy to take that code and bring it to an Azure Function or in any .Net Core Application that runs anywhere (Linux, Windows, Mac Os, web, containers, etc.)!

Today, I was running around with my laptop trying to find someone to show him what I did. My problem was that since I'm working from home, I found no one except my dog... Toby, did you see what I just did! He was looking at me and didn't really care about that I was doing some C# in Atom, a regular text editor. So, here I am now, sharing my discovery with you.
The "What"
While reading some article on the Internet, I fall on a video talking about OmniSharp.
A family of Open Source projects, each with one goal - To enable great .NET development in YOUR editor of choice.
SO I decide to give it a try in one of my favorite text editors this time called Atom.
Less than two minutes after, I was running across my house....
The "How"
What I like about Atom that it is so easy to install and to customize. The easiest way to install it is via Chocolatey.
Chocolatey NuGet is a Machine Package Manager, somewhat like apt-get, but built with Windows in mind.
Assuming that you don't have Chocolatey installed, let's start by that. Open a command prompt (cmd.exe) as Administrator, and execute this command:
In a new command prompt again with the administrator permission, let's Install the text editor Atom:
cinst Atom
and Git:
cinst Git
Now to install the OmniSharp in Atom you have two options. You could do it through the Settings or using a console. For this post, I will use the second option. Let's open a new command prompt, always as Administrator.
The reason why I use a new prompt every time is to be sure that environment variable gets refreshed.
using System;
namespace ConsoleAppDemo
{
class Program
{
static void Main(string[] args)
{
var myBook = new Book{Title="Get Started with OmniSharp"};
Console.WriteLine(String.Format("Here is my review of: {0}", myBook.Title));
}
}
public class Book
{
private string _review;
public string Title{get;set;}
public string Review{
get{
if(String.IsNullOrEmpty(_review))
{
_review = "This book is nice";
}
return _review;
}
set{
_review = value;
}
}
}
}
Nothing special until you start the OmniSharp server with Ctrl-Alt-o.
Boom!
As you can see now the intelisense, completion, code navigation and so more! If you click on the little green flame on the bottom left you see details about notification and error message.
The end
OmniSharp is a frontend compiler, not a complete compiler so it doesn't generate CLI code. But It's already a lot. Today, you can use OmniSharp with Sublime Text 3, Atom, Emacs, Brackets, Vim and with command line only. So whether on your old laptop or your new PC, whether you run Linux, Mac or Windows let's do some C#!
