How is Docker different from a virtual machine?

Question

I keep rereading the Docker documentation to try to understand the difference between Docker and a full VM. How does it manage to provide a full filesystem, isolated network

Answer 1

In my opinion it depends, it can be seen from the needs of your application, why decide to deploy to Docker because Docker breaks the application into small parts according to its function, this becomes effective because when one application / function is an error it has no effect on other applications , in contrast to using full vm, it will be slower and more complex in configuration, but in some ways safer than docker
