Ansible Role: CoreDNS

Description

Deploy CoreDNS using ansible.

Requirements

Ansible >= 2.7 (It might work on previous versions, but we cannot guarantee it)

Role Variables

All variables which can be overridden are stored in defaults/main.yml file as well as in table below.

Name	Default Value	Description
`coredns_version`	1.6.7	CoreDNS package version
`coredns_binary_local_dir`	""	Allows to use local packages instead of ones distributed on github. As parameter it takes a directory where `coredns` binary is stored on host on which ansible is ran. This overrides `coredns_version` parameter
`coredns_dns_port`	53	Port on which CoreDNS will listen for DNS requests
`coredns_config_file`		This should contain path to file with coredns configuration Corefile

Example

Playbook

Use it in a playbook as follows:

- hosts: all
  roles:
    - cloudalchemy.coredns

Zone files

The role will search in coredns/zones in the Ansible templates paths for files to deploy. These can be used with the file plugin.

Local Testing

The preferred way of locally testing the role is to use Docker and molecule (v2.x). You will have to install Docker on your system. See "Get started" for a Docker package suitable to for your system. We are using tox to simplify process of testing on multiple ansible versions. To install tox execute:

pip3 install tox

To run tests on all ansible versions (WARNING: this can take some time)

tox

To run a custom molecule command on custom environment with only default test scenario:

tox -e py35-ansible28 -- molecule test -s default

For more information about molecule go to their docs.

If you would like to run tests on remote docker host just specify DOCKER_HOST variable before running tox tests.

Travis CI

Combining molecule and travis CI allows us to test how new PRs will behave when used with multiple ansible versions and multiple operating systems. This also allows use to create test scenarios for different role configurations. As a result we have a quite large test matrix which will take more time than local testing, so please be patient.
