# OpenShift DNS Setup

This playbook uses the role [**ansible-role-bind**](https://github.com/bertvv/ansible-role-bind) 

from Bert Van Vreckem to configure a minimal DNS server with a wildcard address 

on the preferred zone.

Its purpose is to provide a reliable resolution mechanism during OpenShift lab 

installations.

### Cloning:

This repository has submodules, hence recursive cloning is necessary:

```

$ git clone --recursive https://github.com/giannisalinetti/openshift-dns-setup.git

```

### Usage:

```

ansible-playbook playbook.yml

```

### Configure additional hosts:

To configure hosts in the zone edit the **vars/main.yaml** file:

```

bind_zone_master_server_ip: "{{ ansible_default_ipv4.address }}" 

bind_recursion: true

bind_zone_minimum_ttl: "2D"

bind_zone_ttl: "2W"

bind_zone_time_to_refresh: "2D"

bind_zone_time_to_retry: "2H"

bind_zone_time_to_expire: "2W"

bind_zone_domains:

  - name: 'extlab.io'

    name_servers:

      - "{{ ansible_hostname }}"

    hosts:

      # The ns master entry

      - name: "{{ ansible_hostname }}"

        ip: 

          - "{{ ansible_default_ipv4.address }}"

      # The wildcard address entry

      - name: "{{ wildcard_name }}"

        ip: 

          - "{{ wildcard_ipv4 }}"

      # Extra entries

      - name: host1

        ip:

          - 192.168.122.20

      - name: host2

        ip:

          - 192.168.122.21

      - name: host3

        ip:

          - 192.168.122.22

    networks:

      - "{{ network }}"

bind_forwarders:

  - "{{ upstream_dns }}"

bind_allow_query:

  - any

bind_listen_ipv4:

  - any

```

For the sake of readability the most common parameters like wildcard address/nmae,

forwareders, etc are defined in the main playbook file and recalled as internal

variables in the vars file.

```

    dns_zone: "extlab.io"

    wildcard_name: '*.apps'

    wildcard_ipv4: 192.168.122.220

    network: 192.168.122

    upstream_dns:

      - 192.168.122.1

```
