Importing/adding a yum .repo file using Ansible

I'm trying to install MariaDB (or any software) from a custom repository using Ansible but I am not sure how to import the .repo file using the yum/yum_repository modules.

Ansible

Here is my playbook:

-
    hosts: all
    become: true
    remote_user: root
    tasks:
        -
            name: set system timezone
            timezone:
                name: America/Toronto
        -
            name: add custom repository
            yum_repository:
                name: centos_o
                description: custom repositories
                baseurl: http://example.net/mirror/centos_o.repo
        -
            name: ensure mariadb is installed
            yum:
                name: mariadb-server-5.5.*
                state: installed

I've tried all include, metalink, baseurl, and mirrorlist with no luck. Also I am missing the GPG key step, but I can't even get the repo added properly.

The centos_o.repo file looks like this:

# JENKINS
[jenkins]
name=CentOS-$releasever - JENKINS
baseurl=http://example.net/mirror/jenkins/
enabled=0
gpgcheck=1

# MariaDB 5.5
[mariadb]
name=CentOS-$releasever - MariaDB
baseurl=http://example.net/mirror/mariadb/yum/5.5/centos$releasever-amd64/
enabled=0
gpgcheck=1

# MariaDB 10.0
[mariadb]
name=CentOS-$releasever - MariaDB
baseurl=http://example.net/mirror/mariadb/yum/10.0/centos$releasever-amd64/
enabled=0
gpgcheck=1

Shell

This is the shell script version that I am trying to convert to Ansible:

yum clean all
yum-config-manager --add-repo=http://example.net/mirror/centos_o.repo
yum-config-manager --enable mariadb
rpm --import http://example.net/mirror/mariadb/RPM-GPG-KEY-MariaDB

If it makes any difference, I am running this with Vagrant's Ansible local provisioner on a CentOS box.

Use the shell command with the creates flag. That will skip the step if the repo file exists. You'll need to make sure you know what the repo file is called.

- name: Add CentOS_o repository
  shell: yum-config-manager --add-repo=http://example.net/mirror/centos_o.repo
  args:
    creates: /etc/yum.repos.d/centos_o.repo 

If you need to add any architecture to the url use something like

- name: Add CentOS_7_speciality repository
  shell: yum-config-manager --add-repo=http://example.net/{{ ansible_distribution | lower }}/{{ ansible_distribution_major_version }}/{{ ansible_architecture }}/
centos_o.repo
  args:
    creates: /etc/yum.repos.d/centos_o.repo 

Ansible will replace the variables with

{{ ansible_distribution | lower }} == centos
{{ ansible_distribution_major_version }} == 7
{{ ansible_architecture }} == x86_64
