List of hosts that will be reached directly, bypassing the proxy. Specify wild card domain use the following form .<DOMAIN> and | as delimiter, for example: localhost|.my.host.com|123.42.12.32 Only use when configuring a proxy is required. Operator respects OpenShift cluster wide proxy configuration and no additional configuration is required, but defining nonProxyHosts in a custom resource leads to merging non proxy hosts lists from the cluster proxy configuration and ones defined in the custom resources.
