A. Prepare System Charts

The System Charts repository contains all the catalog items required for features such as moniotring, logging, alerting and global DNS. To be able to use these features in an air gap install, you will need to mirror the system-charts repository to a location in your network that Rancher can reach and configure Rancher to use that repository.

B. Configure System Charts

Rancher needs to be configured to use the Git mirror of the system-charts repository.

  1. Log into Rancher.
