# ps-exporter via Proxy Configuration

If your cluster does not have access to the Internet and you are utilizing a proxy server you can connect the exporter via proxy in order to use PerfectScale.

To configure ps-exporter via proxy you'll need to modify the helm chart while [connecting the cluster](https://docs.perfectscale.io/getting-started/how-to-onboard-a-cluster) (step: deploy PerfectScale) with additional settings (lines 6,7,8 and 9 in the following command):

{% code lineNumbers="true" %}

```yaml
helm upgrade --install -n perfectscale --create-namespace perfectscale \
  --set secret.create=true \
  --set secret.clientId="CHNAGE_TO YOUR" \
  --set secret.clientSecret="CHNAGE_TO YOUR" \
  --set settings.clusterName="CHNAGE_TO YOUR" \
  --set settings.httpProxyEnabled=true \
  --set settings.httpProxy="http://proxy.net:8080" \
  --set settings.httpsProxy="http://proxy.net:8080" \
  --set settings.noProxy=".corp\,.svc\,.cluster\,.local\,172.30.0.1\," \
  perfectscale/exporter
```

{% endcode %}

:six:`--set settings.httpProxyEnabled=true` - enables proxy

:seven:`--set settings.httpProxy="http://proxy.net:8080" \` - your proxy URL with the `http` protocol

:eight:`--set settings.httpsProxy="http://proxy.net:8080" \` - your proxy URL with the `https` protocol

:nine:`--set settings.noProxy=".corp\,.svc\,.cluster\,.local\,172.30.0.1\," \` - the TLDs are allowed without proxy

{% hint style="info" %}
To use PerfectScale via a proxy, ensure that your proxy server allows `http` and `https` connections to the following endpoints:

* registry.k8s.io
* api.app.perfectscale.io/
* app.perfectscale.io
* perfectscale-io.github.io
* public.ecr.aws
* customer-data-prod-perfectscale-io.s3.eu-central-1.amazonaws.com
