We have been hearing a lot about Dockers and containers; they are said to be the next big things in the world of technology. I decided to explore the enigma that was Docker and I must say it's really impressive.
Introduction
What is Docker?
Whenever we have to install software, we have to take care of a lot of things. There are lots of different versions of software available for different operating systems and their different versions. You have to go through the documentation and choose the correct fit for your needs and then run the executive file. Even after that, you may need to complete some other steps before you are able to use that software. Docker runs containers, which contain the software plus the dependencies that the software requires to run. Just use a docker run command with the name of the image that you want to install, and your software runs in its own container, using its own resources. You do not have to worry which version of the software suits your operating system. I will demonstrate this with an example of a MongoDB installation.
