FAQs on Docker Installation
Q. What is the difference between running a Linux container on a Linux machine and a Linux container on a windows machine?
Ans. It doesn’t matter what the host machine is, the Linux container will behave similarly on every other platform. But the networking and the storage will be different on Windows running a Linux container. The Linux host machine is always preferred over Windows by the Enterprises and Developers since Linux machines are more reliable, developer-friendly, and secure.
Q. What is the difference between the Stable and Edge versions of Docker Desktop?
Ans. The Stable Version provides a general availability release-ready installer for a fully tested and more reliable application. It includes the latest released version of the Docker Engine. The release schedule is synced with Docker Engine releases and patch releases.
The Edge channel provides an installer with new features we are working on but is not necessarily fully tested. It includes the experimental version of the Docker Engine. Bugs, crashes, and issues can occur when using the Edge version, but you get a chance to preview new functionality, experiment, and provide feedback as Docker Desktop evolves.
