Description

Installs:

• apache using the apache cookbook
• keepalived using the keepalived cookbook

Configures:

• a floating IP for the reverse proxy service
• an apache reverse proxy for each openstack service

Requirements

Chef 0.10.0 or higher required (for Chef environment use). This cookbook assumes that it's being used in a deployment based on the rcbops cookbooks.

Platforms

• Ubuntu >= 12.04

Cookbooks

The following cookbooks are dependencies:

• keepalived
• osops-utils
• apache2

Recipes

default

• Iterates through the list of services provided in the attributes/environment
• Uses node['openstack-proxy']['vips'] to add floating IP's using keepalived
• Uses node['openstack-proxy']['services'] to search for the appropriate back-ends and create the reverse proxies for each of them

attributes

Using the example:

    "openstack-proxy": {
      "use_ssl": true,
      "vips": {
        "192.168.4.114": {
          "vrid": 13,
          "network": "public",
          "public_name": "api.example.com"
        }
      },
      "services": {
        "192.168.4.114": {
          "keystone-service-api": {
            "role": "keystone-api",
            "namespace": "keystone",
            "service": "service-api"
          },
          "keystone-admin-api": {
            "role": "keystone-api",
            "namespace": "keystone",
            "service": "admin-api"
          },
          "nova-api": {
            "role": "nova-api-os-compute",
            "namespace": "nova",
            "service": "api"
          }
        }
      }
    }

• use_ssl is a global setting to make all reverse proxies listen via ssl
• the virtual ip of 192.168.4.114 with keepalived using a virtual router id of 13 on the osops_network 'public' and all reverse proxies on that address have the servername directive of 'api.example.com'. The virtual router ID must be a value between 1 and 255 and must be unique!
• three services are setup for reverse proxy: the keystone service api, keystone admin api and nova api. The role, namespace and service values must come from the openstack-ha cookbook attributes.
