Kubernetes configmaps

A ConfigMap is an API object used to store non-confidential data in key-value pairs inside kubernetes.
GO Feature Flag can read directly in a configmap in your namespace.

The Kubernetes Retriever will access flags in a Kubernetes ConfigMap via the Kubernetes Go Client.

Add your config file as configmap

kubectl create configmap goff --from-file=examples/retriever_configmap/flags.yaml

Configuration Example

import (
    restclient "k8s.io/client-go/rest"
)

config, _ := restclient.InClusterConfig()
err = ffclient.Init(ffclient.Config{
    PollingInterval: 3 * time.Second,
    Retriever: &k8sretriever.Retriever{
        Path: "file-example.yaml",
        Namespace:      "default"
        ConfigMapName: "my-configmap"
        Key:    "somekey.yml"
        ClientConfig: &config
    },
})
defer ffclient.Close()
