calico-dhcp-agent should pass additional config file dhcp_agent.ini

[jcat]

While trying to get MTU settings to openstack clients via DHCP, I found that any changes made to the neutron dnsmasq file where not passed to dnsmasq by calico-dhcp-agent.

Adding the neutron dhcp config file, dhcp_agent.ini, as an additional config file for calico-dhcp-agent, seemed to enable setting in dnsmasq to take effect as expected.

I propose changing the systemd unit from:

ExecStart=/usr/bin/calico-dhcp-agent --config-file /etc/neutron/neutron.conf

..to:

ExecStart=/usr/bin/calico-dhcp-agent --config-file /etc/neutron/neutron.conf --config-file /etc/neutron/dhcp_agent.ini

..or creating some other mechanism, where by extra config files can be optionally specified without changing the unit file.

If you want any further info, please let me know.

Cheers,
Just

The thing is that it still not updating nameservers from subnet details to resolv.conf file

But the resolving work well.
