Docker-compose is awesome: it’s brings automation levels high, driving apps close to be 12 factor. But some times it’s being too smart (for me particularly). This time a couple of words on dynamic network creation.
Backing up and restoring data in rails projects is trivial enough. But when using docker and docker-compose things may become a bit cumbersome.
When you manage one or two packages, it’s a good idea
to spin up a virtual machine as build environment just
for that. Using some tricks it can be made possible to
build them automatically.
Here I want to show fully automated approach using headless build host inside a Docker container.
