Just look at a few days, use LNMP environment for example, to see if my understanding is correct, please everybody to give some guidance to think from the Angle of practical use, to establish the concept of a practice, specific as follows:
1. The first installation docker, step-by-step, no longer tired above;
2. Login docker ID;
3. The image began to push all need package: PHP/MYSQL/NGINX, etc., as needed;
4. Start the various images package to the container;
5. Configuration parameters setting, such as site path, etc.;

OK, complete the Docker LNMP environment set up,
But I have a question, dockerfile in this process is a dispensable?
Simply put this a few necessary mirror into the container to run together, go together?
