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

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
