Wind River Linux

Wind River Linux is an embedded systems OS from Wind, an Intel Company. You can get more details on this from their product page.

Beaker provides support for 2 of Cisco’s Wind River Linux platforms. Those platform codenames are cisco_nexus for Cisco NX-OS based systems and cisco_ios_xr for Cisco IOS XR based systems.

Beaker currently can install puppet on Cisco Nexus and Cisco IOS XR.

Host Requirements

WRLinux hosts validate their setup once created, and will fail if not setup correctly. There are two conditions that are validated specifically on WRLinux hosts. These conditions are listed below.

A. All Cisco Nexus hosts will need a :vrf value, which determines their virtual routing framework for networking purposes. For our purposes, we tend to use the value management, so there is always a hosts file line that looks like this in our configuration:

HOSTS:
:
…
vrf: management

B. All Cisco hosts will also require a user to be set on the hosts. This is because they don’t allow ssh'ing as the root user, which is one of the main assumptions that Beaker operates under in the usual case. In order to specify a user to ssh with, add this block to a host:

HOSTS:
:
…
ssh:
user:

Hypervisors

WRLinux has only been developed and tested as a vmpooler host.

This doesn’t mean that it can’t be used in another hypervisor, but that Beaker doesn’t specifically deal with the details of that hypervisor in creating WRLinux hosts, if there is anything specific to WRLinux that will need to be done in provisioning steps.

Installation Methods

Open Source

In order to install a puppet-agent against a WRLinux host, you’ll have to use the install_puppet_agent_on method.

It reaches out to the WRLinux-specific host code for any information that it needs. You can check out these methods if you need more information about this.
