Hi, today we will learn how to build a Nginx reverse proxy/Load Balancing server using Weave and Docker. Weave can create a virtual network to connect the Docker containers to each other, supporting deployment across hosts and automatic discovery. It allows us to focus more on the development of the application rather than the infrastructure. Weave provides a great environment, as if all of its containers b

Using virtual machine can solve some problems, make good one VM image and throw it on hypervisor, but it's too heavy. Using containers (Container) can be a good solution, especially when Docker uses layered mirroring to make container mirroring easier to publish and migrate.Docker is not a simple container software anymore, but an ecosystem.
