Docker is a tool that makes creating, deploying, and running applications easier with the use of containers. Now, what are containers? These can be described as something that makes it possible for developers to spruce up an application with all the parts needed for it. These could include libraries, for instance, along with other dependencies. Docker assembles all these and presents them as one package. The container gives the developer the assurance that the application will run on just about any Linux machine, no matter to what extent any of its customized settings in a particular machine could be at variance from those on the machine on which the code is written and tested.

Who is Docker for:

Docker is aimed to benefit both developers and system administrators. This makes it a part of many DevOps (developers + operations) toolchains. The main benefit that Docker carries for developers is that they can concentrate on their core job of writing the code without having to bog themselves down with which system it will run on.

How Docker is useful in the IT industry:

The most vital use of the Docker Enterprise container platform is that it offers value to a business by drastically bringing down its cost on infrastructure and maintenance. It can also do the same when it comes to migrating current. Best of all, all these can be done immediately upon installation. In this way, it saves time, as well. The following infographic illustrates how Docker brings down costs and increases productivity in an enterprise:

Ever Wondered Why We Use Containers In DevOps?

At some point we've all said the words, "But it works on my machine." It usually happens during testing or when you're trying to get a new project set up. Sometimes it happens when you pull down changes from an updated branch.

Docker manifest - A peek into image's manifest.json files

The docker manifest command does not work independently to perform any action. In order to work with the docker manifest or manifest list, we use sub-commands along with it. This manifest sub-command can enable us to interact with the image manifests. Furthermore, it also gives information about the OS and the architecture, that a particular image was built for. The image manifest provides a configuration and a set of layers for a container image. This is an experimenta

Docker Explained: Docker Architecture | Docker Registries

Following the second video about Docker basics, in this video, I explain Docker architecture and explain the different building blocks of the docker engine; docker client, API, Docker Daemon. I also explain what a docker registry is and I finish the video with a demo explaining and illustrating how to use Docker hub.
