Wow thank you! I understand now about the COPY part in the docker file. I had to go back up and re-read your explanation. Makes sense now.
I'm certainly interested in trying these things out - but at the moment I think it will introduce a great many other things that I need to learn and I think I will wait for a bit. But your post certainly helped clear some things up in my head about what docker containers are all about.
So please correct me if I'm wrong, but I'm curious about the following:
locally you have a container set up for development. You have this docker file and etc.
locally anyone on your team can then easily set up the same environment because they can use the same docker file
server side you also have the same docker file but that container is constantly running to serve a website or whatever
I assume that you would also use version control for all of this, including the docker file. I also assume that the container running on the server has some kind of way to update files from version control when a commit is done on a certain branch. (I know that hooks exist for this sort of thing with GitHub but I don't have experience with this yet.)
If you have the time, I'd be interested to read more about this sort of stuff in another dev.to post. Diagrams are helpful for sure! There's a lot of moving parts for all of this technology and it's a challenge to see how things fit together.
Yes using dockerfile, you can build and share your image. There is a version control for docker images, hub.docker.com/, here you can store and share your images.
I did not understand your last question, could you please elaborate?

Hey Dan,
Yes using dockerfile, you can build and share your image. There is a version control for docker images, hub.docker.com/, here you can store and share your images.
