LaunchDarkly Kubernetes FlagToggle Controller

This is a reference implementation for a kubernetes controller to toggle LaunchDarkly flags via the API.

Requirements

Go 1.12+ installed
Kubebuilder v2.0.0-alpha.4 - The binaries that are part of the release must be under /usr/local/kubebuilder/bin.

Setup

You need a local or remote kubernetes cluster running. For local you can use kind

1. Add the CRD definition to your cluster: kubectly apply -f config/crd/bases/featureflags.launchdarkly.com_flagtoggles.yaml
2. You need to have a LaunchDarkly API Key with write permissions. Once you get the key you can add it as an environment variable in your current environment with the key LD_API_KEY
3. make run will start the controller on your local machine and connect to kubernetes based on your KUBECONFIG environment variable.

sample-crd.yaml is a sample that you can modify to match a field in your environment.
