Automated builds for multiple containers

Question

I have a few containers that are expected to run together. Do I need to create a tiny github repository for each (seems wasteful and inconvenient), or can I use the same github repository as a source for an automated build of multiple containers?

Answer 1

If the containers are expected to be run together then use docker compose to build and run them. The Docker file associated with each container can then be kept in a sub directory.

Example

├── docker-compose.yml
├── one
│   └── Dockerfile
└── two
    └── Dockerfile

docker-compose.yml

web1:
  build: one
  ports:
    - 8080
web2:
  build: two
  ports:
    - 8080
