Build isolated environments for deploying.ĭocker helps you to simplify and automate every step of the software development process.Multiple containers can reuse these layers. A container is distributed in the form of an image, which consists of multiple layers.A container is lighter than a virtual machine, so that it can be launched way faster.As soon as is launched, a container determines a runtime environment for your application.A container is a package for the software and all required libraries.The container has the following characteristics: To achieve its goal, Docker is using containers. It is the standard de facto for packaging and sharing apps – from desktop to the cloud.
