** Target ** ・ I've heard that more and more web-based development companies are using Docker: frowning: ・ I'm interested but don't know what to do: disappointed_relieved:

A file that automatically generates a Docker image.
Go to Docker Hub and install Docker. https://hub.docker.com/editions/community/docker-ce-desktop-mac ↓ CREATE ACCOUNT ↓ Install with ** Get Docker ** ↓ Check if it was installed correctly
$docker version Version: 19.03.13
Installation is complete when version is displayed.
Specify the "hello-world" image published by Docker officially and start the container.
$ docker run hello-world
I think the following display was displayed. It just says ** Hello from Docker! ** on the console, so if it does, it's working fine.
Unable to find image 'hello-world:latest' locally latest: Pulling from library/hello-world
Hello from Docker!
** Image list display command **
$ docker images
