# Proxy configuration

The Reference Configuration for Rancher on HPE SimpliVity supports deploying Rancher in environments that require the use of a proxy to access the internet. Configuration variables for the playbooks must be specified, while the Ansible controller itself must also be properly configured.

# Proxy configuration variables

Proxy configuration is specified in the proxy dictionary variable and are described in the table below.

Variable	File	Description
`proxy.http`	group_vars/all/vars.yml	Hostname or IP address of the HTTP proxy server and the proxy port number separated by a colon. For example: "http://web-proxy.hpecloud.org:8080". Mandatory if proxy support is required.
`proxy.https`	group_vars/all/vars.yml	Hostname or IP address of the HTTP proxy server and the proxy port number separated by a colon. Typically, this is identical to the `http_proxy` value. Mandatory if proxy support is required.
`proxy.except`	group_vars/all/vars.yml	A comma-separated list of hostnames, IP addresses, or network ranges that should bypass the proxy server. The list should include: localhost, the configured domain name used to deploy the Rancher cluster, the DHCP subnet CIDR, and the vCenter hostname. Mandatory if proxy support is required.

A sample proxy configuration is provided in the file group_vars/all/vars.yml.sample:
