I use cloud66 for my sideproject https://backmail.io . All the components are dockerized, and deployed/managed through cloud66 stack. For a smaller projects/teams, cloud66 provide an easier way to get everything working with single click ssl , easy scaling , and provide both vertical and horizontal scaling either using cloud vm's or your custom dedi machines. It also supports CI pipeline, to build docker images, though i use my own jenkins setup to build docker images.
