OMG: Micro Framework

A micro-framework for the excellent Open Microservices Guide, for suppportive code written in Python 3.6+.

Note: this is pre-release software, and is subject to improvement. Contributions are welcome!

Intended / Example Usage

$ cat service.py

import micro
from uuid import uuid4

service = micro.Service(name='uuid')

@service.register('/uuid4', method='get')
def gen_uuid4(prefix: str) -> str:
    """Generates a UUID, with a given prefix."""
    return f'{prefix}{uuid4().hex}'

# Alternative Syntax:
# service.add(f=gen_uuid4)

if __name__ == '__main__':
    service.serve()

If not available on disk, the required Dockerfile and microservice.yml files will automatically be generated, for your application:

$ cat microservice.yml
actions:
  uuid4:
    help: Generates a UUID, with a given prefix.
    http:
      method: get
      path: /uuid4
      port: 8080
    output:
      type: string
omg: 1

$ cat Dockerfile
FROM kennethreitz/pipenv
COPY . /app
CMD ["python3", "service.py"]

Now, run your microservice!

$ python service.py
2019-05-09 14:45:39,342 - micro - DEBUG - Initiating 'uuid' service.
2019-05-09 14:45:39,344 - micro - DEBUG - Registering Flask endpoint: '/uuid4'
2019-05-09 14:45:39,344 - micro - DEBUG - Dockerfile './Dockerfile' already exists!
2019-05-09 14:45:39,345 - micro - DEBUG - Microservice Manifest './microservice.yml' already exists!
2019-05-09 14:45:39,346 - micro - INFO - Serving on: '*:8080'

Or, use the omg-cli:

$ omg run uuid4 -a prefix='user-'
…

Installation

$ pip install omg-micro

P.S. This doesn't work yet. :)
