# K8S Global Objects



This utility creates "global" objects accross all Kubernetes Namespaces



Supports the following objects types: **ConfigMap** and **Secret** for now



> This utility will get build in a container

> The container will run inside k8s

> it needs rolebinded service account and roles (take a look at deploy folder in this repo)



#### Usage



Just add an Annotation with key **MakeGlobal** and value of *true* to add or *false* to remove, to a supported object



Example:

```

apiVersion: v1

kind: ConfigMap

metadata:

  name: someconfigmap

  namespace: default

  annotations:

    MakeGlobal: "true" # or "false"

```



#### Running Options

```console

Usage of k8s-global-objects:

  -debug

        Debug

  -kubeconfig string

        KUBECONFIG location (default "/Users/latchmihay/.kube/config")

  -runinterval duration

        interval to kick off sync (default 1m0s)

  -runonce

        Run App once

```



#### Running in kubernetes

Look at **deploy** folder



#### Run Time Log
