Air Gapped Environment

This section describes how to use Harvester in an air gapped environment. Some use cases could be where Harvester will be installed offline, behind a firewall, or behind a proxy.

The Harvester ISO image contains all the packages to make it work in an air gapped environment.

Working Behind an HTTP Proxy

In some environments, the connection to external services, from the servers or VMs, requires an HTTP(S) proxy.

Configure an HTTP Proxy During Installation

You can configure the HTTP(S) proxy during the ISO installation as shown in picture below:

iso-proxy

Configure an HTTP Proxy in Harvester Settings

You can configure the HTTP(S) proxy in the settings page of the Harvester dashboard:

  1. Go to the settings page of the Harvester UI.
  2. Find the http-proxy setting, click ⋮ > Edit setting
  3. Enter the value(s) for http-proxy, https-proxy and no-proxy.

proxy-setting

Note

Harvester appends necessary addresses to user configured no-proxy to ensure the internal traffic works. i.e., localhost,127.0.0.1,0.0.0.0,10.0.0.0/8,cattle-system.svc,.svc,.cluster.local
