Re: [Openstack] external dhcp server instead of dnsmasq

[Ritesh Nanda]

Thanks Mark,
I tried it and it works, would like to appreciate the idea behind it. As i
am using vlan manager in nova-network , i would like to create a new domain
for each tenant created in keystone.That tenant would be having a seprate
network.
I can understand the process , i would even try that , but can you give me
more brief idea , how to do that.

Re: [Openstack] external dhcp server instead of dnsmasq

[Mark Lehrer]

Or is there any way in openstack i can implement dynamic dns in openstack.


If you want your VM's to automatically get a DNS entry, I have a MyDNS
add-on that can do it.  MyDNS is a DNS server that uses a database
instead of zone files.

You just have to pick a domain or subdomain, and then make a union
between the standard MyDNS RR table and the Openstack instances table.  I made
a .deb of it that includes MyDNS and documentation on how to create the union,
you can grab it at:

http://knm.org/mydns-mysql_1.2.8.31_amd64.deb

I was planning to update it for Grizzly and I also wanted to maybe try PowerDNS,
but I have been using this system since May and it works pretty well.  Let me 
know
if you have any questions.

Re: [Openstack] external dhcp server instead of dnsmasq

[Vishvananda Ishaya]

nova dhcp and dns architecture won't change. But I'm sure an alternate dhcp 
implementation could be done as a quantum l3 plugin. So that combined with 
moniker would likely be the path forward.

 Hello ,
 
 Is it possible to use external dhcp server , instead of dnsmasq .
 I am using openstack essex, with vlan manager as network,  I have a need 
 where i need to implement dynamic dns, 
 so using dhcp3 as dhcp-server and bind9 as dns is possible.
 
 Or is there any way in openstack i can implement dynamic dns in openstack.
 
 One more problem which i am facing , dnsmasq has a option to assign static 
 ip to a particular hostname using dhcp-host
 parameter in dnsmasq config file.
 
 i tried it doing by defining  the config file of dnsmasq in nova.conf
 
 --dnsmasq_config_file=/etc/nova/dnsmasq.conf
 
 then in dnsmasq config file 
 
 i gave options for a particular subnet.
  
 
 dhcp-range=Tenant-operator,10.0.50.3,10.0.50.254,255.255.255.0,24h
 dhcp-option=Tenant-operator,6,10.0.50.7
 domain=operator.com,10.0.50.0/24,local
 dhcp-host=importantmachine,10.0.50.120
 
 these all options are working except dhcp-host.
 
 Can anybody help me with this.

Re: [Openstack] external dhcp server instead of dnsmasq

[Ritesh Nanda]

Thanks again vish

Do we have any roadmap to include a functinality for using ISC-dhcp and
bind dns as default in openstack. As with the release of Bind 10 a lot of
functionality would be getting change from how bind9 worked. Now ISC-dhcp
would be saving lease files in database and lot more.
Even moinmoin project running to provide DNSaas in openstack  that supports
bind 9 at present would there be any future change in nova dhcp and dns
architecture to the currently it has.

Re: [Openstack] external dhcp server instead of dnsmasq

[Vishvananda Ishaya]

It is unfortunately regenerated every time an instance is launched, but if you 
want to test editing it is referenced in the commmandline for dnsmasq. for 
example on devstack:

--dhcp-hostsfile=/opt/stack/data/nova/br100.conf

No particular reason except that is what libvirt uses by default and it is easy

This is something I always forget to ask: I'm curious about the historical

Re: [Openstack] external dhcp server instead of dnsmasq

[Ritesh Nanda]

Thanks vish,

 Can you tell me the location of the external host file we provide to
dnsmasq , so that i can try putting the directive there.

Re: [Openstack] external dhcp server instead of dnsmasq

[Vishvananda Ishaya]

You cannot have an external dhcp server with openstack. Openstack needs a way 
to know the ip address assigned to a vm to do its listing properly. If you 
don't care about the api returning valid ips there is a possibility of using 
FlatNetworking (not FlatDHCP) to make nova stick the network into a bridge and 
not do any dhcp at all. You could then have an external server serving up dhcp 
ips. I suspect you will probably have to disable security groups completely 
using NoopFirewallDriver driver to get this to work.

As to the reason dhcp-host is not working, I suspect is because we give dnsmasq 
an external hosts file so you probably would need the host directive there.

[Openstack] external dhcp server instead of dnsmasq

[Ritesh Nanda]

Hello ,

Is it possible to use external dhcp server , instead of dnsmasq .
I am using openstack essex, with vlan manager as network,  I have a need
where i need to implement dynamic dns,
so using dhcp3 as dhcp-server and bind9 as dns is possible.

Or is there any way in openstack i can implement dynamic dns in openstack.

One more problem which i am facing , dnsmasq has a option to assign static
ip to a particular hostname using dhcp-host
parameter in dnsmasq config file.

i tried it doing by defining  the config file of dnsmasq in nova.conf

--dnsmasq_config_file=/etc/nova/dnsmasq.conf

then in dnsmasq config file

i gave options for a particular subnet.


dhcp-range=Tenant-operator,10.0.50.3,10.0.50.254,255.255.255.0,24h
dhcp-option=Tenant-operator,6,10.0.50.7
domain=operator.com,10.0.50.0/24,local
dhcp-host=importantmachine,10.0.50.120

these all options are working except dhcp-host.

Can anybody help me with this.
