Hello. Mun: grinning: I decided to use Docker for the next project, so I tried to touch it a little. I wrote it as a memorandum for myself, but I hope this article will be useful for those who touch Docker for the first time! Feel free to comment if you have any mistakes about the content of the article or any advice you should do: sunny:
Let's visit for the first time!
Please refer to the following article. p>

Type the following command into the terminal, get the image of nginx from Docker hub, and start the container.
docker run --name some-nginx -d -p 8080:80 nginx
If the port of a process that has already started is covered and you get angry, either drop the process that has already started or start the container on a different port.
If the startup is successful, RUNNING will be displayed as shown below.

Access the following URL from your browser.
If the screen below appears, the container has been started successfully!
