Usually, when the developer has built a module and everything works as expected at the developer end. When same code is sent it to QA it fails. Docker tries to bridge these gaps and comes handy while shipping the codes between many environments. Docker allows us to create the containers for software applications.
Virtual Machines vs Docker.
Docker uses the single Operating System and virtualizes apps only in it whereas Virtual Machines(VM) virtualize their guest Operating System on the top of the Host's Operating System. Below screenshot helps to understand the difference in a better way:
Solomon Hykes and his team have developed Docker and in this short video, he explains Why we built Docker. For quick introduction go through introduction-to-docker.
There are many video tutorials to learn Docker but below video tutorials are helpful to master in the Docker.
But before going through the below Docker video tutorials, you need have knowledge of Windows/Linux commands, having prior experience in any programming language such Python, Java, Node JS, Ruby, PHP etc,. and knowledge about networking is an added advantage for you.
Also, you can go through the Docker tutorials and Docker - Egghead. If you think that any best video tutorials are missing in the above list, please let us know by commenting, so that it is helpful for Docker aspirants.
What is Docker?
Docker is a container technology that helps to create, distribute and run container images on any server. Docker helps to create a standardized format sandbox so that sandbox can be used in any environment. In simple words, Dockers makes sure that our code works in all environments. |
