DNS¶
DNS is currently hosted by Red Hat IT, on Red Hat hosted servers. While being less than ideal from a openess point of view, we currently do not have the required ressources to replace that, and due to the criticity of DNS, this is not a priority to be changed.
To modify it, someone with access to the internal dns-maps server need to send the commit.
The current list of persons with access are:
i. Michael Scherer
ii. Nigel Babu
If needed, RH IT can also do a modification and/or grant access.
Naming conventions¶
In order to be able to use specific domain name matching with ansible, the following naming convention is used.
For ip hosted in Rackspace cloud, we use *.rax.gluster.org
.
For ip in the Community cage, we use *.rht.gluster.org
.
If the ip is internal and on the VLAN 401 (Common, also called Internal), the domain
should be *.int.rht.gluster.org
.
If the ip is on the VLAN 400 (Management, also called Admin), the domain should be
*.adm.rht.gluster.org
.
Historical servers may use *.rack.gluster.org
and *.cloud.gluster.org
, but newer servers
no longer use this. We try to keep the *.gluster.org
naming for externally visible name.
Ideally, they should only be used for CNAME on real server name. This is done to permit potential
migration or change without impacting external users.
