Important: RKE add-on install is only supported up to Rancher v2.0.8
Please use the Rancher helm chart to install HA Rancher. For details, see the HA Install - Installation Outline.
If you are currently using the RKE add-on install method, see Migrating from an HA RKE Add-on Install for details on how to move to using the helm chart.
If you operate Rancher behind a proxy and you want to access services through the proxy (such as retrieving catalogs), you must provide Rancher information about your proxy. As Rancher is written in Go, it uses the common proxy environment variables as shown below.
NO_PROXY contains the network addresses, network address ranges and domains that should be excluded from using the proxy.
|HTTP_PROXY||Proxy address to use when initiating HTTP connection(s)|
|HTTPS_PROXY||Proxy address to use when initiating HTTPS connection(s)|
|NO_PROXY||Network address(es), network address range(s) and domains to exclude from using the proxy when initiating connection(s)|
Note NO_PROXY must be in uppercase to use network range (CIDR) notation.
