Azure Storage Exploration!

Hey There, during my work studying for my Azure Exam/Working on my Hug the Cloud project. I’ve found accessing and understanding my stored data a bit confusing.

Luckily, someone shared this link with me.
Here you can find a number of available azure file/table/queue explorers.

I chose the first explorer ‘Azure Storage Explorer’
It works well, is easy to use, and is totally free.

Once you have it downloaded you’ll be met with this page:

Use add account to create a new storage view.
Use add account to create a new storage view.

Go to your azure portal and find the info about your storage account in the ‘manage access keys’ section. (You can see the manage access keys button at the bottom of this photo):

From Azure Portal select Storage -> 'Name of Storage Account'
From Azure Portal select Storage -> ‘Name of Storage Account’

Use the name and the primary key and put that info in here:
putinhere

This has made it much easier for me to organize my project data, and understand what’s happening inside my storage accounts.

Notice the three different types of storage? (Blob, Queue, and Table)

MEAN Stack on Ubuntu Server Setup

Let’s say you’re at your first hackathon. You have an idea you want to develop quickly and manage and deploy remotely so you’re ready to scale, or aggregate data cross platform. Buzzwords.

I’ve seen it many times in my last 3 months of attending hackathons.

Students want to get started quickly without wasting time worrying about deployment and compatibility across devices this setup will also prepare them to work in a team because it’ll allow deployment from Git. And these principles carry down into innovation initiatives happening at companies around the world one solution is MEAN.

Let’s say you’re new to web development and you’re learning node but don’t want to gunk up you machine with installations and moving files around before you have a grasp of what really matters.

That’s where MEAN in the Cloud comes in.

So what we’re going to do is install the MEAN stack on a cloud server so we can mess with code, learn, restart, and more without worrying about ruining our machine.

This whole process will take place in eight steps:
First: Setup Ubuntu Server
Second: Get into server
Third: Install Mongo
Fourth: Install Node
Fifth: Create first Node app
Sixth: Install NPM
Seventh: Install Express and Angular using NPM
Eighth: Get a tiny server running

First: Setup Ubuntu Server

1. Login to Azure (Create an account if you don’t have one already)
Using azure isn’t required any cloud hosting that provides and Ubuntu distro should work.

2. In the bottom left click “New”

3. Next to Compute Virtual Machine

4. Select Quick Create

5. Give it a name (eg. meanincloud)

6. In IMAGE dropdown select ‘Ubuntu 14.04 LTS’

7. Leave the size at the default – you can always scale later.

8. Provide a password and confirm it

9. Select the region nearest to you.

10. Hold tight, the cloud is provisioning resources and configuring your machine.

11. After status reads running double click on ‘meanincloud’

12. Then select ‘DASHBOARD’

13. Scroll down until you see SSH details on the left.

14. take note of those values it should be something like: ‘youservername.cloudapp.net: 22″
This is your server host name and the SSH port we’ll be using this in the next section to access your remote machine

We now have a Linux VM with the Ubuntu distribution. This is our base on which we’ll build the MEAN stack.

Second: Get into Server

For this part we’ll need an SSH client. Putty is what I’ve always used and works well for this instance. Download page

1. in the box labeled Host Name (or IP address) paste ‘yourservername.cloudapp.net’ and leave the port at 22.

2. You’ll likely receive a PuTTY security alert. That’s cool for now, select Yes.

3. If you’re using azure you’re login will be ‘azureuser’

4. And you’re password will be that same that you provided at ‘7.’ in the previous section.

5. You’re now at the Ubuntu terminal (Like cmd). You’ll start at home, but you can get to root by entering: ‘cd /’ and back to home with ‘cd ~’

6. Now we get MEAN

Third: Install Mongo

The Mongo installation instructions can be found here if you’re curious. But we’ll run through that here.

Note: All lines in bold will be run in the terminal. Copy and right click to paste into your putty shell. Then press enter to run the command.

1. Import the public key used by the package management system:
~$ sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 7F0CEB10

2. Create a list file for MongoDB
~$ echo 'deb http://downloads-distro.mongodb.org/repo/ubuntu-upstart dist 10gen' | sudo tee /etc/apt/sources.list.d/mongodb.list
No result will display.

3. Reload local package database.
~$ sudo apt-get update
You’ll get about 15 seconds of output.

4. Install the MongoDB packages – This will download the latest stable version, but you can be specific if you liked an older version. Read more into it here.
~$ sudo apt-get install -y mongodb-org
You’ll get about 30 seconds of output.

5. Reload local package database
~$ sudo apt-get update

Alright! Mongo is installed, here’s a great tutorial if you want to get a better understanding of how Mongo works.

Fourth: Install Node

Node is the web app framework that you’ll be building you application with. Although its not spelled MNEA or NMEA, this more accurately represents the priority of these tools.

1. Install Node:
~$ sudo apt-get install nodejs

2. Confirm install with ‘Y’
About 20 seconds of output.

3. Node is now installed you run node by entering nodejs this will take you to the Node REPL.

4. Try it out
~$ nodejs

5. In the REPL you can run javascript
> console.log('hello world');

6. ctrl+c twice will exit the repl.

Fifth: Create your first Node app

We now have everything we technically need to start development with Node, the first thing we’ll do is create a hello world app to begin putting the pieces together.

1. First install emacs24 an inline text editor for linux that will allow us to make changes to code inside our terminal.
sudo apt-get install emacs24
a ‘Y’ will be required to finish
And we’ll get about a minute of output.
Now we can edit code right here! No need to worry about messing up your own file system.

2. Make sure we’re updated.
~$ sudo apt-get update

3. make a directory to hold our demo
~$ mkdir mean-practice

4. ‘ls’ will show us our newly created directory

5. Change into that directory
~$ cd mean-practice

6. now we’ll create our first file inside of that directory.
/mean-practice$ emacs package.json
This will open a new emacs view that will allow us to make changes, save ctrl+x+s and close ctrl+x+c.

7. This is our basic manifest file. type this into it.

{
"name" : "mean-practice",
"version": "0.0.1"
}

This is the minimum. As you learn more about node you’ll see what else will go in there.
ctrl+x+s to save and ctrl+x+c to exit.

8. Let’s create our main file, basically our entry point for the application, and where the server will begin operating.
/mean-practice$ emacs server.js

9. put this into that file:
console.log("Hello World with NODE!");
Though possibly over-zealous this is our first node app!
ctrl+x+s to save and ctrl+x+c to close.

10. Type ‘ls’ to see what’s in our mean-practice directory.
Not a ton, but everything we need to start our application.

11. Let’s run our application:
/mean-practice$ nodejs server
Sweet! All we’ll get as output is “Hello World with NODE!” but that’s better than a kick to the face.

12. To stop the server press ctrl+c

Sixth: Install secret N, NPM

Node strengths and rapid growth are due in large par to the awesome npm. A package manager which will allow you to import a whole host of clever tools, apps, widgets, and formatting helpers to make your node development as easy as possible. So let’s install that now.

1. First install NPM.
/mean-practice$ sudo apt-get install npm
You’ll need another ‘Y’
and expect about 45 seconds of output.

2. Update again
/mean-practice$ sudo apt-get update
another 20 seconds of output

Seventh: Now we’ll install Express and Angular using NPM.

Now that NPM is installed we can add our final packages!

1. Install express
/mean-practice$ sudo npm install express --save
express is in the npm system and –save will edit our package.json file to include the express module. Click this link to find out more about express.
Expect about 15 seconds of output.

2. Enter ls to see our new directory ‘node_modules’ where our node modules are being stored.

3. Open package.json to see the changes in our manifest.
/mean-practice$ emacs package.json
You’ll now see under dependencies “express”
Yay! Now express is installed.
ctrl+x+s to save and ctrl+x+c to exit.

4. Now lets install angular.
/mean-practice$ sudo npm install angular
Now the angular module is part of our application! Click on the link above to learn more about Angular.

That’s it! Now you have a MEAN stack ready for development!

Let’s quickly build a simple server, configure an endpoint in azure and become a client with our browser.

Eigth: Get a tiny server running

1. Open our server.js
/mean-practice$ emacs server.js

2. Replace our hello world statement with:


var express = require('express');
var app = express();

var port = 3000;

app.get('/', function(req, res) {
res.send('hello from afar');
});

app.listen(port, function(){
console.log("Listening at port: " + port);
})

4. Now our server.js is actually a server but our virtual machine doesn’t know that. Go back to your azure portal.

5. Select Endpoints at the top between monitor and configure.

6. At the bottom select ‘ADD’

7. Select ‘ADD A STAND-ALONE ENDPOINT’

8. Press the arrow

9. Under the NAME dropdown select HTTP

10. Leave protocol at TCP

11. Leave public port at 80

12. Change the private port to ‘3000’
We’re mapping our endpoints improperly for this demo to keep things simple. As you learn more about web development you’ll want to change your endpoints to accurately reflect what’s happening in your server.

13. Hit the checkmark.

14. Back in your putty shell run the server!
/mean-practice$ nodejs server.js

15. Open a new tab in your browser and navigate to: ‘yourservername.cloudapp.net’

16. CHECK IT OUT! You’ve got a website running node on a virtual machine! Throw your hands in the air! You’re ready to hack and learn.

Here are some learning resources to get you started.
