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 (, so I guess that maybe DO have its own too. Thank you.

Hey friend,

Great question! We don’t have one, but our images are basically just this:

That said, I’d like to focus more on the reasons for doing it, as I think there may be a better path.

Making MySQL start on boot should be just something like this:

systemctl enable mysql

That enables the service to start on boot. No need to test it, as it will work unless another circumstance exists that needs your manual intervention, such as a corrupted database. There’s really no good way to automate that specific scenario that doesn’t put you at greater risk.
