I am new to docker, and would like to learn to use it. So, I am working though the tutorials. The first one is on a page titled “What is a container?” See What is a container? | Docker Docs
The issue I am having is that step #2 results in a message: “Image not supported”. When I hover over the message a pop-up displays: “Docker is running windows containers.” Here are the steps:
Open Docker Desktop and select the search.
Specify docker/welcome-to-docker in the search and then select Run.
Results: “Image not supported”. When I hover over the message a pop-up displays: “Docker is running windows containers.”
Expected Results: The container runs.
That documentation is a little misleading. A container is an isolated process. That’s true, but it is not necessarily running in Docker Desktop which runs a virtual machine for Linux containers. If it says “image not supported” and “Docker is running windows containers” that means you haven’t switched to Linux containers and you could only run Windows containers as the most important thing about containers is that they can’t run different operating systems like vitual machines. If you run Windows without a Linux VM (switching to linux containers) than you can only run Windows in containers. I can’t create a screenshot, I’m not on Windows, but click on the Docker icon in the notification area and then “Switch to Linux containers” or something like that.
