[chef] Re: Re: Re: Re: Re: Re: Re: Re: How do I configure /etc/network/interfaces using chef?

[Booker Bense < >]

I'd double vote this suggestion. There is a huge chicken and egg problem in using a network based CM to manage the network interfaces. 

We've been using such a system ( not chef ) for 10 years and it causes as many problems as it solves. 

If you need to automate the network config, then you need something like Cobbler.

I would suggest that you don't use chef for this.  Instead, put the creation of interfaces into your build process, e.g. kickstart

Hi Maciek,

Definitely agree about the docs.  I have a Trello card open right now to deal with that in the next few weeks.

Barthélemy’s example will probably serve your purposes but in case it doesn’t, please let me know if there are any specific questions I can answer in the mean time.  I do not own the cookbook but I am a contributor to it.

Ohai !

I'm working regularly with this cookbook's author. Don't hesitate to create a github issue asking for some doc if you feel the need to.

Actually I'm using this very simple resource to manage my server's eth0 :

network_interfaces 'eth0' do
  target '10.10.16.203'
  mask '255.255.128.0'
  gateway '10.10.1.253'
end

there is other options you can use, you'd better look at lwrp ressource file to understand how it can work, and what can be changed :

attribute :device, kind_of: String, name_attribute: true

attribute :bridge, kind_of: [TrueClass, FalseClass, Array]

attribute :bridge_stp, kind_of: [TrueClass, FalseClass]

attribute :bond, kind_of: [TrueClass, FalseClass, Array]

attribute :bond_mode, kind_of: String

attribute :vlan_dev, kind_of: String

attribute :onboot, kind_of: [TrueClass, FalseClass], default: true

attribute :bootproto, kind_of: String

attribute :target, kind_of: String

attribute :gateway, kind_of: String

attribute :metric, kind_of: Integer

attribute :mtu, kind_of: Integer

attribute :mask, kind_of: String

attribute :network, kind_of: String

attribute :broadcast, kind_of: String

attribute :pre_up, kind_of: String

attribute :up, kind_of: String

attribute :post_up, kind_of: String

attribute :pre_down, kind_of: String

attribute :down, kind_of: String

attribute :post_down, kind_of: String

attribute :custom, kind_of: Hash

Are there some usage examples? This cookbook's documentation is severely lacking - I'm not proficient with Chef yet, so I'm having a hard time understanding how to use it.

Not sure if this is useful for your particular case but if what you’re trying to do is set up some existing physical NICs (or virtual NICs if you’re in a cloud computing environment) there is a cookbook for that:

I'm going to take an initial whack at this, and say I "think" its going to be something like

node[network][interfaces].each do |nic|

[whatever you want to do here]

Youll probably wanna add a bit of logic just after that first line to help ignore it is the nic is the lo nic.

Other will certainly improve on this.

I'm looking for a way to configure N (N=3) ubuntu nodes with 2 network interfaces each - since I'm a complete newb, what is the proper way to do it?
