K8s DNS stack by Kargo
|
||
|
|
======================
|
||
|
|
|
||
|
|
Here is an approximate picture of how DNS things working and
|
||
|
|
being configured by Kargo ansible playbooks:
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
Note that an additional dnsmasq daemon set is installed by Kargo
|
||
|
|
by default. Kubelet will configure DNS base of all pods to use that
|
||
|
|
dnsmasq cluster IP. You can disable it with the ``skip_dnsmasq``
|
||
|
|
var. This may be the case, if you're fine with Linux limit of max 3
|
||
|
|
nameservers in the ``/etc/resolv.conf``. When skipped and bypassed
|
||
|
|
directly to Kubedns's dnsmasq cluster IP, it greatly simplifies things
|
||
|
|
by the price of limited nameservers though.
|
||
|
|
|
||
|
|
Nameservers are configured in the hosts' ``/etc/resolv.conf`` files
|
||
|
|
from the ``nameservers`` (see also ``searchdomains``) vars. While the
|
||
|
|
``upstream_dns_servers`` will define additional DNS servers for the
|
||
|
|
dnsmasq daemon set running on all hosts (unless bypassed with
|
||
|
|
``skip_dnsmasq``).
