Heimdall is a reverse proxy that will take an Open API 3.0.1 definition and spin up a reverse proxy to a backend service using https://golang.org/pkg/net/http/httputil/#ReverseProxy
This POC aims to prove the concept of abstracted authentication and authorization layer from the actual service provider, it acts as a Man in the Middle sniffing the request and the response to control access to a service and also make sure the service provider is compliant with the predefined json interface. (similar to AWS API Gateway)
It sets up a router from the json and proxy passes the requests to a backend server if will also validate the response back from the server against the API schema.
Also has support for $refs in the json schema it will combine all refs to a
single large minified json.
It does the sniffing part right now and logs the request/response which is the main point, there is not a lot of validation going on, but since we have access to the request we can do anything we please when a request comes it and when a response is being sent out.
compose up if you just wanna see it in action
docker-compose -p h up --buildthen go to http://localhost:8844/status in your browser
you should see the logs from heimdall_1 and dummy_service_1 in the terminal where you ran the docker-compose command
the below command will grant you a shell with root access inside of a golang 1.8 container with the volumes mounted
# get a shell
bash cli.sh
# once inside to download the deps
go get -v github.com/drmjo/heimdall
# install the bin
go install -v github.com/drmjo/heimdall
# run
heimdall --help
