Service discovery with Docker, Consul and Registrator

Tra­di­tion­ally com­put­ers were named and not eas­ily re­placed in the event it broke down. Server soft­ware was lis­ten­ing on a hard-coded port, and to link pieces to­gether these ma­chine names and ser­vice ports were hard-coded into other soft­ware's con­fig­ura­tion files. Now in the era of cloud com­put­ing and ser­vice ori­ented ar­chi­tec­ture this is no longer an ad­equate so­lu­tion, thus elas­tic scal­ing and ser­vice dis­cov­ery are be­com­ing the norm. One easy so­lu­tion is to com­bine the pow­ers of Docker, Con­sul and Reg­is­tra­tor.
