Apart from the dependency stuff, what you need to migrate when you use docker-compose is just a text file and the volumes that hold the data. No full VMs that contain entire systems because all that stuff is just recreated automatically in seconds on the new machine.
Comment on Should I move to Docker?

Ok, that does save a lot of overhead and space. Does it impact performance compared to a vm?

If anything, containers are less resource intensive than VMs.

Thank you. Guess i really need to take some time to get into it. Just never saw a real reason.

If you update your OS, it could happen that a changed dependency breaks your app. This wouldn’t happen with docker, as every dependency is shipped with the application in the container.

Ah okay. So it’s like an escape from dependancy-hell… Thanks.
