What is the best way to push from github to production server?

Question

git

I read here how people use github in their website development and decided to implement this approach in their work. Everything is clear and beautiful, but a small question arose, which everyone technically bypasses in their manuals.
How development is being done is more or less clear to me. As a result, we got the finished product and want to deploy it to the production server. The question arises - is this done simply by the git clone command? And as a result, a .git folder is formed on production?
Or is it somehow transferred to production in some other way?
Sorry for the noobness.

Answer 1

no, no git clone (although this can be seen as a primitive form of deployment). We assemble the build (roughly speaking, an archive with everything you need, all third-party dependencies, etc. to unpack and run) and deploy it. Rolling migrations, clearing caches, etc.

It is fashionable now to arrange Continuous_Integration. There are free services wercker.com , https://travis-ci.org/. Such a service will catch the github_hook after the commit, test it in the specified environment, and if the tests pass, it will deploy the stage to production with the possibility of rollback. In such a pipeline, you can develop on a tablet or mobile phone.
