Generate Dockerfile for running a service

[php-coder]

Despite Dockerfile is useful by itself, it also needed for running integration tests on CI (#13)

• express (js/ts)
  • https://docs.docker.com/language/nodejs/containerize/
  • https://github.com/nodejs/docker-node
• golang
  • https://docs.docker.com/language/golang/build-images/
  • https://tachingchen.com/blog/building-minimal-docker-image-for-go-applications/
• fastapi
  • https://docs.docker.com/samples/fastapi/
  • https://fastapi.tiangolo.com/deployment/docker/
• https://docs.docker.com/reference/cli/docker/init/
• README: how to run app in Docker
• console output: how to ru app in Docker

Also could be useful: https://github.com/docker/awesome-compose

Later, we can also generate docker-compose.yml file.
