What is Docker?

Docker is a tool for creating, deploying and running applications in containers. Containers are a virtualization technique where applications are isolated from each other and from the underlying operating system. In this way, you can easily move and run applications on different platforms. Docker has become very popular in recent years and there are many benefits to using it. Docker's abstraction of the operating system makes it easy to create and deploy applications. There is no need to worry about compatibility issues and the applications run the same way regardless of the platform. However, there are downsides to Docker. The container's isolation makes it difficult to debug applications and there is some overhead in running applications in containers. Compared to other virtualization technologies such as VMware and VirtualBox, Docker is much easier to use. There is no need to install any software on the underlying platform and there is a very large ecosystem of tools and services to facilitate the use of Docker.Läs mer
