Fabric8 toggles service

Overview

The fabric8-toggles-service is the client service to run with the fabric8-toggles server. The server is heavily based on Unleash server, a feature toggle system, that gives you a great overview over all feature toggles across all your applications and services. It comes with official client implementations for Java, Node.js and Go.

fabric8-server defines 4 level of toggle configuration: internal, experimental, beta or released. The activation strategy is per userGroupId.

Using the admin console deployed with fabric8-toggle, you can easily move a feature from experimental to beta. This client makes use of the unleash Go SDK to connect to fabric8-toggles server.

You can see usage of the service in fabric8-ui.

$ make clean build

Run test

To run unit tests:

make build test

Docker build

build image from centos

make image

run your docker image in minishift

make deploy-minishift

Deploy locally:

F8_TOGGLES_URL=http://toggles-fabric8.192.168.64.4.xip.io/api F8_AUTH_URL=https://auth.prod-preview.openshift.io make run

where F8_TOGGLES_URL points to the exposed route on minishift and F8_AUTH_URL target prod-preview.
