debops.stunnel does not create any tunnels by default, they need to be
defined by the user. A antural place for them is usually a host group in
As an example, let’s create an encrypted tunnel between two hosts, one of which acts as a MySQL server, and other is a client which connects through the tunnel to the server.
This is an example Ansible hosts file, located in
defines two host groups:
[mysql_encrypted_tunnel] dbserver dbclient [debops_mysql] dbserver [debops_stunnel:children] mysql_encrypted_tunnel
inventory/group_vars/mysql_encrypted_tunnel/stunnel.yml you should
define your MySQL tunnel connection:
--- stunnel_services: - name: 'mysql-ssl-tunnel' server_accept: '3307' server_connect: '3306' client_accept: '3306' client_connect: 'dbserver:3307'
debops.stunnel will try and select the correct host as a server/client
automatically, using a number of factors. By default all hosts are treated as
clients; if automatic detection of a server fails, you will be able to override
This configuration sets up only
stunnel4 service, configuration of the
firewall and TCP wrappers can be performed using additional configuration
parameters. See Guides and examples for more details.
This is an example playbook which can be used to configure
stunnel on all
hosts that use it - they should be present in
either directly or indirectly via a child group:
--- - name: Manage stunnel connections hosts: debops_stunnel roles: - role: debops.stunnel tags: stunnel
