Again, I know nothing about your projects. There are plenty of youtube videos and tutorials about Docker Desktop that show the benefit of Docker Desktop like using extensions to add more funcionality or run Kubernetes single-node cluster easily, search for Docker images, start containers, check the logs, execute commands in containers or backup volumes but it won’t help if you have no idea what to look for.
You will still need to use powershell or command line if you want to build a Docker image or start a compose project, but on Windows Docker Desktop is the easiest way to instal Docker to run Linux containers. You could install Docker CE in a virtual machine, but then you couldn’t use Docker Desktop extensions or start run Kubernetes with just a couple of clicks.
I prefer to use Docker CE on Linux, but I use Docker Desktop on my MacBook, although not for the GUI.
Since I don’t use Docker Desktop on Windows frequently, I can’t share the best video tutorial, but here is one:
This is about an older version, but the basics are the same. You can also hear about extenions from this video:
If you want to know why you should or should not use Docker Desktop, you will need to share more information about the project.
Was that one person? Can you ask that person what they meant by that?
