Negotiator

Negotiates between an RHMAP core and a OpenShift master. It understands both. It uses the OpenShift client and Kubernetes client to directly interact with the Kubernetes API and OpenShift API. For example when a new cloud app from RHMAP needs to be deployed or a new environment needs to be created, a request will be sent to negotiator with the details required such as a giturl, an auth token, env vars etc. Negotiator will take care of turning this into the required OpenShift Objects and sending them on to OpenShift / Kubernetes directly.

Try it out locally.

ensure go 1.7 or greater installed
clone this repo into $GOPATH/src/github.com/feedhenry/negotiator
cd $GOPATH/src/github.com/feedhenry/negotiator/cmd/negotiator
go build (will be slow the first time but faster afterwards as we have to vendor kubernetes and oscp)
./negotiator

In a separate terminal run the following

oc new-project se
curl http://localhost:3000/deploy/se/cloudapp -H Content-type:application/json -d '{"repo": {"loc": "https://github.com/feedhenry/testing-cloud-app.git","ref": "master"}, "target":{"host":"AN OPENSHIFT MASTER","token":"AN OPENSHIFT TOKEN"}, "serviceName": "cloudapp4","replicas": 1,  "projectGuid":"test","envVars":[{"name":"test","value":"test"}]}'

curl http://localhost:3000/deploy/se/cache -H Content-type:application/json -d '{"serviceName": "cache","replicas": 1,  "projectGuid":"test", "target":{"host":"AN OPENSHIFT MASTER","token":"AN OPENSHIFT TOKEN"}}'

Using the cli


cd $GOPATH/src/github.com/feedhenry/negotiator/cmd/services 
go install . 
services deploy -h
