Hello,
I’m new to all this and looking for some general advice on what’s the best way of transfering my existing DigitalOcean image (droplet) into a docker image.
Thankfully, i’m still at the beginning of my project and I haven’t done the code yet, only the configuration/security of the Ubuntu OS along with SSL certificates are done.
My main concerns are:
- Do I have to recreate the docker image/configuration, or can I just take the image from DigitalOcean?
- If no1 is not possible, how do I reload my SSL certificates using Let’s Encrypt/certbot? I’ve already backed up the “/etc/letsencrypt” folder, do I just need to upload that (after what is done)?
I can’t seem to find any tutorials for the above two questions. Any help would be greatly appreciated.
Thank you.

Hello friend!
Happy to help as best I can. Docker might not be the right solution for you, given the question. Docker is at it’s best when you separate out each part and create a dockerfile for each container that allows you to spin up new instances of that environment at any time. For example, in a web stack I might have a separate container for each item:
- MySQL
- Web server
- Interpreter (PHP, for example)
You would definitely need to build with Docker in mind rather than build outside and then move into Docker, as it would involve re-tracing a lot of your steps.
For your #2 question there, I assume by reloading the LE cert you mean renewing. Let me know if that is an incorrect assumption. Otherwise, this part of the tutorial will help with that: https://www.digitalocean.com/community/tutorials/how-to-secure-nginx-with-let-s-encrypt-on-ubuntu-18-04#step-5-—-verifying-certbot-auto-renewal
