DNS for instances
Hi all, I am having a bit of an issue with DNS for instances. We are wanting to update our DNS servers that all instances use. I have tested this by using google's nameservers for now and set both of our subnets to use "8.8.8.8 & 8.8.4.4", I have also changed the "dhcp_agent.ini" on our Neutron nodes to have: dnsmasq_dns_servers = 8.8.8.8, 8.8.4.4 I have restarted the dhcp agents on both nodes, however whenever a new instance is launched, it is still using the old DNS server setup. Is there anything else I need to do or anything I have missed to make sure instances use the updated DNS servers? Many thanks, Grant -- Grant Morley Cloud Lead Absolute DevOps Ltd Units H, J & K, Gateway 1000, Whittle Way, Stevenage, Herts, SG1 2FP www.absolutedevops.io <http://www.absolutedevops.io/> grant@absolutedevops.io <mailto:grant@absolutedevops.io> 0845 874 0580
Hi All, No worries I have managed to fix this - I missed one of our subnets which was causing the issue. Many thanks, On 19/03/2019 13:49, Grant Morley wrote:
