Stouts.openvpn

Ansible role that installs an openvpn server

• Install and setup OpenVPN server
• Setup authentication

Requirements

Previous versions of the role supported generating certificates and keys for the OpenVPN server to use. Since version 3.0.0, such support has been removed and the users of the role are expected to use some other way of generating certificates/keys (eg using another Ansible role). See the example playbook for an example.

An EasyRSA role that was created specifically to compliment this role can be found here.

Supported platforms

• Ubuntu 14.04
• Ubuntu 16.04
• Ubuntu 18.04
• Debian 8
• Debian 9
• Centos 7

Variables

See defaults/main.yml for a full list of variables together with documentation on how to use them to configure this role.

Elastic Beats monitoring

Heartbeat monitor

The role comes bundled with a meta/monitors.yml template that can be used by Heartbeat to check if the OpenVPN server is up and running. The template can be configured via variables (they should be self-explanatory). To use it, you can use some Ansible tasks to upload it to your Heartbeat instance. For example:

- name: Add earth-kibana host
  add_host:
    name: heartbeat_instance
    hostname: "{{ heartbeat.hostname }}"
    ansible_host: "{{ heartbeat.ansible_host }}"
    ansible_password: "{{ heartbeat.ansible_password }}"
    ansible_user: "{{ heartbeat.ansible_user }}"

- name: Upload role monitors
  template:
    src: "{{ item.1 + '/' + item.0 }}/meta/monitors.yml"
    dest: "/etc/heartbeat/monitors.d/{{ inventory_hostname }}.{{ item.0.split('.')[-1] }}.yml"
  when: (item.1 + '/' + item.0 + '/meta/monitors.yml') is file
  loop: "{{ roles | product(lookup('config', 'DEFAULT_ROLES_PATH')) | list }}"
  delegate_to: heartbeat_instance

Filebeat input

The role also includes a filebeat input file that can be uploaded to a filebeat server. The input reads the OpenVPN log and reads the lines that correspond to successful connections. The role includes an Elasticsearch ingest pipeline that can be imported to Elasticsearch to parse and break the log lines into fields. The files can be found under the meta/ folder.

Example playbook
