How does C ++ know that a container class has a push_back function?

Question

When I look at std::back_insert_iterator http://en.cppreference.com/w/cpp/iterator/back_insert_iterator

It says that the container's push_back method will be called. How do I know if a container has a push_back method? Is a class that extends any virtual class required, and where is it defined?
