CumulusLinux

An Ansible role to manage Cumulus Linux through NCLU module.

Requirements

Cumulus Linux version 3.2+ only, previous releases do not support NCLU.

Role Variables

Variable	Description	Type	Default
`cl_license`	CumulusLinux license	String	`''`
`cl_hostname`	Hostname of the device	String	`cumulus`
`cl_time_zone`	Timezone	String	`Etc/UTC`
`cl_time_ntp_servers`	NTP servers list, possibility to add iburst option	Array	`[]`
`cl_time_ntp_source`	NTP source interface	String	`eth0`
`cl_locales`	Enable locale from locale-gen	Array	`[]`
`cl_dns_nameserver`	DNS nameserver from two subarray ipv4 and ipv6	Hash	`{}`
`cl_commands`	Ansible nclu atomic commands using recursive lookup, permit del/add actions, played first	Hash	`{}`
`cl_snmp`	snmp-server settings from `net add snmp-server` using recursive lookup	Hash	`{}`
`cl_syslog`	syslog setings from two subarray of hash ipv4 and ipv6, each entry need an ip + a port and optionaly a proto(udp/tcp)	Hash	`{}`
`cl_interface`	interface settings from `net add interface` using recursive lookup	Hash	`{}`
`cl_bond`	bond settings from `net add bond` using recursive lookup	Hash	`{}`
`cl_vlan`	vlan settings from `net add vlan` using recursive lookup	Hash	`{}`

Dependencies

None

Custom Lookup

Recursive

To manage Cumulus Linux interface configuration with Ansible, I coded a lookup plugin to be able to construct the variables from a hash and it will recursivly read the nested hash to transform the hash into a list of strings.

Every depth into the variables will be added to the nclu command like that:

var:

cl_interface:
  swp1:
    ip:
      address: 192.168.1.1/24
    link:
      speed: 100
  swp2:
    bridge:
      trunk:
        vlans:
          - 1-5
          - 10,12

results:

swp1 ip address 192.168.1.1/24
swp2 bridge trunk vlans 1-5
swp2 bridge trunk vlans 10,12

This way I find the structure of the variables more readable for complex settings.
