[chef] Re: Using the ifconfig resource with DHCP?

[AJ Christensen < >]

I would be extremely surprised to learn that the ifconfig core resource/provider still functions at all. Please file a bug :-)

cheers,

I'm trying to use the ifconfig resource to set up an interface to use DHCP (this is on CentOS 6, chef client 12.4.1).

However, I can't figure out how to actually accomplish what I need.

Here is the resource I am using:

ifconfig "eth1" do
  device "eth1"
  onboot "yes"
  bootproto "dhcp"
end

Which expands to:

    ifconfig("eth1") do
      action [:add]
      retries 0
      retry_delay 2
      default_guard_interpreter :default
      target "eth1"
      device "eth1"
      onboot "yes"
      bootproto "dhcp"
      declared_type :ifconfig
      cookbook_name "main"
      recipe_name "default"
    end

I have two problems with it. First, this generates a configuration file named "ifcfg-" instead of "ifcfg-eth1" and second, it copies the resource name into the IP address - which obviously makes no sense for a DHCP interface. Unfortunately, the examples in the documentation are less than helpful, because they all use the IP address as the resource name.

In fact, the documentation actually is self-contradictory when it comes to DHCP. There is an example "Specify a boot protocol" that claims that this is what I'd need - and later the identical code in another example claims to generate a different configuration in the sample "Update a static IP address with a boot protocol"

How do I correctly use the ifconfig resource?

Here is the configuration file it generates:

# cat /etc/sysconfig/network-scripts/ifcfg-


>BOOTPROTO=dhcp
IPADDR=eth1
