oms 0.5.0

A micro-framework for the OMS, and code written in Python 3.6+.

oms.py

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

Note: this is pre-release software, and is subject to improvement. Contributions are welcome! This framework is being developed for other languages, as well. If you'd like to help, let us know!

Intended / Example Usage

$ cat service.py

import oms
from uuid import uuid4

service = oms.Microservice(name='uuid')

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

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

register takes some optional arguments: name and path. You can also call service.add(f=new), instead.

Next, run the command $ oms-generate oms.yml files will automatically be generated, for your application:

$ oms-generate service:service
…
'oms.yml' written to disk!

$ cat oms.yml
actions:
  new:
    help: Generates a UUID, with a given prefix.
    arguments:
      prefix:
        in: query
        required: true
        type: string
    http:
      method: get
      path: /new
      port: 8080
    output:
      type: string
lifecycle:
  startup:
    command:
    - python3
    - /app/service.py
oms: 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: '/new'
2019-05-09 14:45:39,344 - micro - DEBUG - Dockerfile './Dockerfile' already exists!
2019-05-09 14:45:39,345 - micro - DEBUG - Microservice Manifest './oms.yml' already exists!
2019-05-09 14:45:39,346 - micro - INFO - Serving on: '*:8080'

This will spawn a Flask application (using the production-ready waitress web server), preconfigured to serve the masses!

Or, use the oms CLI:

$ oms run new -a prefix='user-'
…

Installation

$ pip install

P.S. Do provide feedback, if you desire! :)
