Does Digital Ocean have a Docker image (or a Dockerfile to create one) that is exactly the same as the one in the Ubuntu 18.04 droplet?

Hi, I would like to “emulate” a Digital Ocean Ubuntu droplet in my Mac (iOS) locally. Does Digital Ocean have an image (or a Dockerfile to create one) that is exactly the same as the one in the droplet? That’s my question, if you need more details about it, there you have:

• Why I’m asking it? I would like to emulate on my Mac what is going on in the server (droplet). For ex, I would like to make mySQL to restart if the server reboots. I can’t reboot the droplet, so I want to test if my code works on my local version. (Actually, can I reboot the droplet to test if mySQL restarts?)
• What have I tried so far? I tried to create an Ubuntu image via Dockerfile (“FROM Ubuntu”), but when I install mysql-server on this image via Dockerfile (“sudo apt install -y mysql-server”) and I open the bash of this image (“exec”), mysql can’t be started (“fail” and “ERROR 2002 (HY000): Can’t connect to local MySQL server through socket ‘/var/run/mysqld/mysqld.sock’ (2)”). If I go inside the bash of the container, uninstall mysql and install manually, then I can run it. But to emulate what I want, I need that the image has mysql running automatically.

I know that Amazon has something similar (https://aws.amazon.com/amazon-linux-ami/), so I guess that maybe DO have its own too. Thank you.
