How to influence DNS hostnames when using the static IP config

Open bassplay3r opened this issue 9 months ago • 0 comments

We are moving from DHCP to static vars.yaml but we want to use our site's DNS and not the DNS on the helper


# cat ocp4-helpernode/vars.yaml
---
ansible_default_ipv4:
  alias: "enp1s0"
  broadcast: "10.192.131.255"
  gateway: "10.192.128.1"
  interface: "enp1s0"
  macaddress: "52:54:00:95:09:92"
  mtu: 1500
  netmask: "255.255.240.0"
  network: "10.192.131.0"
  prefix: "24"
  type: "ether"
disk: vda
ssh_gen_key: false
staticips: true
helper:
  name: "helper"
  ipaddr: "10.192.131.60"
dns:
  domain: "foo.bar.com"
  clusterid: "hjkzitv"
  forwarder1: "10.193.0.250"
  forwarder2: "10.192.0.250"
bootstrap:
  name: "bootstrap"
  ipaddr: "10.192.131.77"
masters:
  - name: "master0"
    ipaddr: "10.192.131.78"
  - name: "master1"
    ipaddr: "10.192.131.79"
  - name: "master2"
    ipaddr: "10.192.131.80"

workers:
  - name: "worker0"
    ipaddr: "10.192.131.81"
  - name: "worker1"
    ipaddr: "10.192.131.82"

When I resolve the nodes I get this

# cat /etc/resolv.conf
search hjkzitv.foo.bar.com
nameserver 127.0.0.1

# host master0
master0.hjkzitv.foo.bar.com has address 10.192.131.78

My nodes are already in our site's DNS as -vm1.foo.bar.com how do I get ocp4-helpernode to create the node names like that instead of master0..foo.bar.com?

is always random since we build the clusters every time we run in the CI
