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.
Passing environment variables to the Rancher container can be done using
-e KEY=VALUE or
--env KEY=VALUE. Required values for
NO_PROXY in a Docker Installation are:
The example below is based on a proxy server accessible at
http://192.168.0.1:3128, and excluding usage the proxy when accessing network range
192.168.10.0/24 and every hostname under the domain
docker run -d --restart=unless-stopped \
-p 80:80 -p 443:443 \
-e HTTP_PROXY="http://192.168.10.1:3128" \
-e HTTPS_PROXY="http://192.168.10.1:3128" \
-e NO_PROXY="localhost,127.0.0.1,0.0.0.0,10.0.0.0/8,cattle-system.svc,192.168.10.0/24,.svc,.cluster.local,example.com" \
As of Rancher v2.5, privileged access is required.
