Mastering Azure with Cloud Shell

Mastering Azure with Cloud Shell

There are multiple ways to interact and manage resources in Microsoft Azure. You can use the Azure Portal or command line tools like the Azure PowerShell module or the Azure CLI, which you can install on your local machine. However, to set up a cloud management workstation for administrators and developers can be quite a lot of work. Especially if you have multiple computers, keeping consistency between these machines can be challenging. Another challenge is keeping the environment secure and all the tools up to date. The Cloud Shell addresses this any many more things.

Cloud Shell is not brand new, Microsoft announced Cloud Shell at Build 2017. This blog post is about how you can master Azure with Cloud Shell and give you an overview of the possibilities of Cloud Shell.

 

What is Cloud Shell

Cloud Shell Azure Portal

Cloud Shell offers a browser-accessible, pre-configured shell experience for managing Azure resources without the overhead of installing, versioning, and maintaining a machine yourself. Azure Cloud Shell is assigned per unique user account and automatically authenticated with each session. This makes it a private and secure environment.

You get a modern web-based command line experience which can be accessed from several endpoints like the Azure Portal, shell.azure.com and the Azure mobile app, Visual Studio Code or directly in the Azure docs.

In the backend, Azure uses containers and automatically attaches an Azure File Share to the container. You can store the data on it, so your data is persistent. This persists your data across different Cloud Shell sessions.

Cloud Shell Bash and PowerShell

You can choose your preferred shell experience. Cloud Shell supports Bash and PowerShell and included your favorite third-party tools and standard tools and languages. If something like a module is missing, you can add it.



VSCode in Azure Cloud Shell

You can now run a Visual Studio Code based editor in Azure Cloud Shell

Azure Cloud Shell, a browser-accessible shell for managing Azure resources, just got even more powerful. Today Microsoft added a new Visual Studio Code editor to Azure Cloud Shell. Okay, it is not the real Visual Studio Code, it is an editor based on the Visual Studio Code open-source project Monaco. Monaco is the same web-standards based editor that powers Visual Studio Code, and the editor is now integrated directly into Cloud Shell.

Now you not only have editors like vim, emacs or nano, you also able to run code, directly with in the Azure Cloud Shell. This is pretty handy when it comes to quickly edit some files like scripts or ARM templates.

This is not the first time the Azure Cloud Shell team and the Visual Studio Code team collaborated: Azure Cloud Shell in Visual Studio Code



My Favorite Visual Studio Code Themes

While I am doing presentations, I often do demos, and since a lot of my demos are PowerShell based, I use a lot of Visual Studio Code. With that I often get the question which is the Visual Studio Code Theme I use. Even I change my Visual Studio Code Themes pretty often, I have a couple of favorites I want to share.

Azure Contrast (rainglow)

VS Code Theme Azure Contrast rainglow

Rainglow has a huge amount for different themes, my favorite one is their Azure, Azure Contrast theme.

Cobalt2

Visual Studio Code Theme Cobalt2

My current favorite Visual Studio Code Theme is Cobalt2. Cobalt2 is a dark but colorful theme for Visual Studio. I like it because it is a dark theme, but it not uses the classic dark grey background, instead I like the mix of dark blue and yellow.

Atom One Dark

Visual Studio Code Theme Atom One Dark

Atom One Dark is another Dark theme I started to like very much. I like the popping colors on the dark background.

Ayu Mirage – Visual Studio Code Theme

Visual Studio Code Theme Ayu Mirage

The Ayu Themes for Visual Studio are simple, bright and elegant themes. I prefer the Ayu Mirage theme which as I said looks very elegant. The Ayu themes also have other options like the Ayu light which is also one of my favorites.

Dracula

Visual Studio Code Theme Dracula

Dracula is one of the famous Visual Studio Code themes, which is also available on other platforms. When I am not using the Cobalt2 theme, I most often switch to Dracula.

Ayu Light

Visual Studio Code Theme Ayu Light

I mentioned the Ayu Themes before, and this is the light version of it. I am mostly using dark themes, but when I switch to a light theme, I mostly use Ayu Light.

PowerShell ISE

Visual Studio Code Theme PowerShell ISE

If you are coming form PowerShell scripting, you are already familiar with the PowerShell ISE. The PowerShell ISE theme bring you back in to the old school world and even gives you the PowerShell blue background terminal.

There are a lot of other great Visual Studio Code Themes out there. What is your favorite? Let me know in the comments!

SVN Basic

subversionA colleague made a pretty cool blog post about svn basic on his blog. Subverion is a software versioning and a revision control system. At work all our program code and scripts, every little piece of code is going in your Subversion repository. This allows you to get back to earlier revisions of the code or simply share and work on code with other employees. Even your documentation is going into the Subversion repository.

On his blog post (German) he shows the basics of subversion, doing a checkout of e repository, adding files, changing files, removing files and more.

Here is a basic list of svn commands, if you need more information you should check the Subversion Homepage or try the Blog post from tspycher.com

svn checkout  http://svn.colab.company.com # SVN checkout
svn commit -m "My Message and Changes" # SVN committing changes and new files
svn add /files/*.* # Adding Files to the SVN Repository after this you have to commit that
svn update # Update your local copy

A lot of IDE’s (Integrated Development Environment) like Visual Studio or Xcode have SVN integrated.



Simple C++ lottery program @KTSI

Here is a simple C++ lottery program done for the KTSI.

#include <iostream>
#include <cstdlib>
 
using namespace std;
 
int main (int argc, char * const argv[]) {
 
	int numberCount;
	int maxNumbers;
 
	cout << "Lottery Game" << endl << "=================================" << endl;
	cout << "How many Lottery Numbers = ";
	cin >> numberCount;
	cout << "from 1 to ? ";
	cin >> maxNumbers;
	cout << "You have chosen " << numberCount << " Lottery Numbers from 1 to " << maxNumbers << endl;
 
	int lotteryNumbers[numberCount];
	int i, j;
	bool newNumber;
 
	srand(0);
	for(i=0; i<numberCount; i++) // get numbers
	{
		do  
		{   // Check Random
			lotteryNumbers[i] = rand() % maxNumbers + 1;
			newNumber = true;
			for (j=0; j<i; j++)
			{  
				if (lotteryNumbers[j]==lotteryNumbers[i])
				{ // Check for existing numbers
					newNumber = false;
				}
			}
		} while (!newNumber);
	}
	for (i=0; i<numberCount; i++)
	{
		cout << lotteryNumbers[i] << " ";
	}
	cout << endl;
}


Powershell

Powershell: Count your Code lines

After Coding some lines in a lot of different files you wanna know how much lines you have coded. There are two (I am sure there are even more) ways to do that. The first one is to get the content of the files (Get-Content) and count the lines in there.

The other way and the fasterway is with Select-String:

(Get-ChildItem -Include *.ps1 -Recurse | Select-String -pattern .).Count
