yarn add kubernetes-configmap-updater
```
* Using npm
```
npm install kubernetes-configmap-updater
```
### Usage
```js
const configUpdater = require('kubernetes-configmap-updater');
configUpdater({
updateUrl: 'https://127.0.0.1:6443/api/v1/namespaces/default/configmaps/example',
frequency: 1000 * 60 * 3,
overwriteExisting: true,
exclude: ['NODE_ENV', 'CUSTOM1','CUSTOM2'],
auth: {
username: 'username',
password: 'password',
token: 'token' // provide token or username/password
}
});
```
* **updateUrl**: Kubernetes configmap api endpoint url
* **frequency**: (Optional) Update interval in ms. Default: `300000`

* **exclude**: (Optional) Exclude keys from being updated. Default: []
