Docker Compose Isn't Enough
Docker Compose creates problems as you scale a single server to many applications. We should learn from it and build something better.
Summary Docker-compose is a tool for working with Docker containers. It solves very real problems with deploying complex applications. By itself it is not enough to make self-hosting applications simple enough for the mass-market. What we need is something like docker-compose, but at a higher level of abstraction that has a concept of SQL databases, local caches, durable storage, service discovery, and resource management.
What does docker do? I’m actually going to assume that you’re already familiar with containerization as popularized by Docker.
