onvif-rest-api-go

The REST API (with notes) of ONVIF protocol, with some architecture concessions for simple integration with Nightbot

Under the hood ONVIF protocol is, I think I may say, a SOAP API.

Go definitions is generated by gowsdl tool.

How to run

1. Clone and build image

docker build -t onvif-rest-api-go:latest .

2. Configure docker-compose

Make changes in docker-compose.yml file according to your needs

3. Run docker-compose

docker-compose up -d

Implemented operations

Main focus is to provide transparent transition from SOAP to REST. So not many validations implemented.
