  D ocker Images start from a base image. The base image should include the platform dependencies required by your application, for example, having the JVM or CLR installed. This base image is defined as an instruction in the Dockerfile. Docker Images are built based on the contents of a Dockerfile. The Dockerfile is a list of instructions describing how to deploy your application. In this example, our base image is the Alpine version of Nginx. This provides the configured web server on the Linux Alpine distribution. I assume that you already know the basics of Docker, and have it installed on your computer. If you haven’t any idea about containerization, then you can refer to this blog-  Installation  and  Getting started with docker . Step 1 - Create Dockerfile Create your  Dockerfile  for building your image by copying the contents below into the editor. FROM nginx:alpine COPY . /usr/share/nginx/html The first line defines our base image. The second line copies the content of the c

Docker is hotter than hot because it makes it possible to get far more apps running on the same old servers and it also makes it very easy to package and ship programs.  Here's a 10k feet overview of what you need to know about Docker. A Docker container can be seen as a computer inside your computer . The cool thing about this virtual computer is that you can send it to your friends; And when they start this computer and run your code they will get exactly the same results as you did. In short, you should use Docker because it allows you to  wrangle dependencies  starting from the operating system up to details such as R and Latex package versions it makes sure that your analyses are  reproducible . There are a couple of other points what Docker helps with: Portability: Since a Docker container can easily be sent to another machine, you can set up everything on your own computer and then run the analyses on e.g. a more powerful machine. Sharability: You can send the Docker contai

Let's discuss about AWS Cloudfront Service. AWS Cloudfront service allows you to live you're static website code on the internet. So that, you don't have to go through traditional website hosting and domain purchase in order to just test you're code functionality and it's UI. If you have a website, application, or another web resource, you probably have static content. Static content includes files like images, videos, or music, or even scripts like .css or js. In the pre-cloud era, you would put those files on a standard server, and then serve them on the internet to all of your viewers, across the globe, from one specific geo location. But with cloud services, there’s a solution that provides faster delivery and better scalability. Here is the flow of what we are going to achieve : Website Code for this Tutorial, you can find on my Github below is direct link, you can either fork or download the source code and use it for demo.

Hi Guys, Sometimes it is important for a network admins to assign an IP address to multiple devices by doing manual calculations if he is working for a small organization who are not able to afford big commercial tools to automatically assign the IP address. This post will share with you a nice python script which helps you to calculate IP ranges available for given subnet mask and it will generate new IP for an admin to assign to a device. Here is the screenshot of the output for reference so than you can determine whether this output will any role in the work routine. Perquisites : You must have python installed. Python 3.7 or above.  You can also run this Python code in any other python supported IDE. Here is the DFD (Data-Flow diagram) of our application : Program Code:         ############# Application #1 - Part #1 ############# import random import sys def subnet_calc():     try:         print ("\n")               #Checking IP addr
