In this case, Approach 2 is put forward to automate the image build process. The idea behind Approach 2 is to write the process of Approach 1 into a Dockerfile and then run the docker build -t test/image:tag. command to automatically build an image from the Dockerfile. In the ...
There’s more to containers (Docker, Vagrant, Rocket) than (re)deployability. They also isolate applications in a discrete Linux namespace, protecting the underlying server (and any other containers) from the nginx process, which is what you want if someone else happens to take it over. Howe...
