Nextgen Gateway FAQs

How do I add proxy settings to Node?

Step-1: Add the proxy settings to /etc/environments.

HTTP_PROXY=
HTTPS_PROXY=
NO_PROXY=localhost,127.0.0.1,10.42.0.1/8,10.43.0.1/8,<NODE_IPs>

Step-2: Login again with the same user for the proxy settings to function properly. Step-3: Now, install the k3s.
Step-4: The proxy settings listed above will also be added to /etc/systemd/system/k3s.service.env

How do I change proxy settings at the node level after installing k3s?

Step-1: Edit the proxy settings in /etc/systemd/system/k3s.service.env
Step-2: Now, use the following command to restart the k3s service:

systemctl restart k3s

Note

The above configurations are only for node level proxy settings such as pulling helm charts etc. and will not be reflected in containers.

How can I enable “squid-proxy” after registering the NextGen gateway?

Follow the below steps to enable squid-proxy.

Retrieve the existing chart version by running the following command:
```
helm list -n <namespace>
```
Replace <namespace> with your gateways namespace. If you don’t have a custom namespace, use default.

Example Output
In this output, the chart version is located under the CHART section. For example, if it says nextgen-gw-18.0.5, the version is 18.0.5.

To enable Squid Proxy, use the following command, replacing <Chart_version> with the version you retrieved and <namespace> with your gateway namespace:

helm upgrade nextgen-gw oci://us-docker.pkg.dev/opsramp-registry/gateway-cluster-charts/nextgen-gw --version <Chart_version> --set squidproxy=enable --reuse-values -n <namespace>
