Docker- What it is?
Docker is a container technology, an open source technology which is used to develop, run and ship applications. The major motto to design Docker is for faster delivery of applications than the traditional technology. Using Docker, you can easily keep your applications separated from the infrastructure. Dockers even allow treating of infrastructure similar to managed application format. Dockers are helpful in fast shipping of scripts, fast testing and deployment and also minimize the cycle between running and writing of code.
Docker achieves this by mingling virtualization of lightweight container technology with tooling and workflows. This is helpful in deployment and management of all your applications easily. The key nature of Docker is that it allows a convenient way of running any of your applications safely and secured within a separate container. These application isolation and security features of Docker help in running many containers at the same time in your host computer. The Docker is of light-weight nature and runs without extra load as that of hypervisors and thus you can extract more from the hardware using Docker technology.
The basics of container virtualization are platform and tooling that are useful in many ways as follows:
Moving the applications along with their components into Docker container For future testing and development, it helps in shipping and distribution It is helpful in product deployment in the application area such as Cloud or local
data centres.
Docker Usages
Quick Delivery of Applications
Docker is best to help you in product development lifecycle. Docker technology paves way for software developers to manufacture local containers containing services and applications. This can again be integrated into deployment and integration workflows.
Example: Imagine that the software developers write their programs in local systems and share them using development stack through Docker among their friends. When ready, the developers may push their coding along with stack they developed into the testing environment. They then execute the code performing various tests needed. From testing platform, the Docker images are then pushed into the production and finally the code deployment.
