balancer

Load Balancer with nginx role.

This role is only for SSL termination setup. Everything from HTTP will be redirected to HTTPS. You can fork and change that or you can contribute to make this optional.

Requirements

Latest Ansible from pip

Platforms

• Ubuntu
• Debian

Role Variables

Name	Default	Value
balancer_vhosts	- { name: "example1", upstreams: ['myserver1.com', 'myserver2.com' ] } - { name: "example2", upstreams: ['myserver1.com', 'myserver2.com' ] }	a list of vhosts
balancer_ssl_key	None	Path to SSL key
balancer_ssl_pem	None	Path to PEM file
balancer_ssl_crt	None	Path to CRT file
balancer_ssl_trusted_crt	None	Path to CRT file of your trusted ssl certificate
balancer_ssl_trusted_key	None	Path to KEY file of your trusted ssl certificate

You need to use either trusted certificates or self signed, using will fail your nginx config

Example

- hosts: localhost
  remote_user: root

  vars:
      - balancer_ssl_key: "/etc/ssl/certs/server.key"
      - balancer_ssl_crt: "/etc/ssl/certs/server.crt"
      - balancer_ssl_pem: "/etc/ssl/certs/server.pem"
      - balancer_vhosts:
        - { name: "my.project.com",  
            upstreams: [
               'node01.myproject.com',
               'node02.myproject.com'
            ]}

  roles:
      - { role: balancer }

Or generate upstreams list from inventory vars group.

Inventory file:

[myproject]
node[01:02].myproject.com

Playbook:

- hosts: localhost
