Ansible Role - openvpn

Installation and Configuring of OpenVPN

Available on Ansible Galaxy: isaackehle.openvpn

Variables

The template for the OpenVPN configuration uses the global inventory list. Each inventory file must include the following in order for the host to be included:

description:
openvpn:
  subnet: aaa.bbb.ccc.ddd
  netmask: lll.mmm.nnn.ooo
  destination: "client" # or 'server'

Note: I found that even though the ansible documentation says that groups.all and groups.ungrouped will give you all of the servers, unless I added my connected systems to a group, the servers were not listed in either group.

Host Definitions typically contain the following:

# Inventory Group that will be included in dns list Inventory entry must also have an ip_address variable
[dns_servers]
server1.domain.com
server2.domain.com

# Name of Ansible Inventory Group of servers that are configured as OpenVPN portals (default = 'portals')
vpn_server_group_name: "portals"

cert_config:
  country: US # Country
  locality: Miami # Locality
  state: FL # State
  organization: My Company # Organization
  ou: My Group # Organizational Unit
  email: [email protected] # Email
  cn: CN # Common name, usually fqdn
  dc: DC # Domain Component, if any

Tags/Flags

I use a system of flags and tags that allow the calling playbook to specify which roles are run. As an example:

ansible-playbook playbooks/openvpn.yml --limit portals -e "{'flags': ['server_config']}" -t server_config

Examples

- hosts: all
    vars:
        target_servers: []
    roles:
      - { name: isaackehle.openvpn }

ansible-playbook playbooks/openvpn.yml -e "{'flags': ['server_init']}" -t server_init
ansible-playbook playbooks/openvpn.yml -e "{'flags': ['server_config']}" -t server_config
