I don't have much experience with Docker so not sure if this is even possible, but I'm trying to export my Docker containers as a single image.
I've created a web server using various images from the official repos (nginx, php7, postgresql). I have a docker-compose.yml file to start each container and link them.
There are volumes for the web hosting root directory and the postgresql data directories.
I now need to export this whole lot, including the volumes so that our technicians out in the field can easily install our web server on client networks. We generally do not have access to the internet on those PCs which is why I can't simply give them the compose and Dockerfiles.
Apologies if I'm not being clear but this is still pretty new to me.
