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()
