Supermarket Belongs to the Community

Supermarket belongs to the community. While Chef has the responsibility to keep it running and be stewards of its functionality, what it does and how it works is driven by the community. The chef/supermarket repository will continue to be where development of the Supermarket application takes place. Come be part of shaping the direction of Supermarket by opening issues and pull requests or by joining us on the Chef Mailing List.

f5-cookbook

A set of resources for managing F5 load balancers. Currently a WIP, but it will create VIPs and pools, and add nodes to pools

Requirements

Platforms

  • RHEL/Fedora and derivatives
  • Debian/Ubuntu and derivatives

Chef

  • Chef 12.7+

Cookbooks

  • none

Attributes

  • node['f5']['gem_version'] - Sets the version of the gem that will be installed via the resource
  • node['f5']['enabled_status'] - Can take one of three values:

|enabled_status value|meaning|
|----------------------|-------|
| :manual | the default, the f5_pool resource does not touch the node's enabled status on load balancer, allowing it to be managed manually on the load balancer |
| :disabled | if a node does not exist or does exist but is enabled, the load balancer will be asked to disable the node |
| :enabled | if a node does not exist or does exist but is disabled, the load balancer will be asked to enable the node |

Usage

Your node will also need access to the credentials for the load balancer either in the attributes or a data bag:

If you're using a data bag, call it f5 and the default item is called default.

$ knife data bag show f5 default
Unencrypted data bag detected, ignoring any provided secret options.
host:     lb1.example.com
id:       default
password: TopSecret
username: chef-api

Or, if no data bag is found, attributes are used

default[:f5][:credentials][:default] = {
  host: "lb1.example.com",
  username: "chef-api",
  password: "TopSecret"
}

Resources

In an application's recipe:

# Creates the pool if missing and adds this node to the pool
# (currently using node.ipaddress and node.fqdn for the node)
f5_pool 'mypool' do
  host 'value'
  port 'value'
  lb_method 'method' # LB_METHOD_ROUND_ROBIN default
end

# Creates the VIP if missing
f5_vip 'myvip' do
  address 'vipaddress'
  port 'vipport'
  protocol 'protocol' # TCP default
  pool 'mypool'
end

See the documentation for LocalLB::LBMethod and protocol.

Manging node enabled status through node attributes

The f5_pool resource exposes an enabled_status property which allows you to explicitly take control of a node's enabled/disabled status within a pool via chef recipes and attributes.

f5_pool 'mypool' do
  host 'value'
  port 'value'
  enabled_status :disabled
end

Though more commonly this is delegated to an attribute, which is the default behavior when this property is not specified explicitly:

f5_pool 'mypool' do
  host 'value'
  port 'value'
end

is equivalent to

f5_pool 'mypool' do
  host 'value'
  port 'value'
  enabled_status node['f5']['enabled_status']
end

and node['f5']['enabled_status'] defaults to :manual so it won't touch the enabled status of your node in the pool unless you explicitly ask it to.

Testing

Run bundle exec rake test to run the chefspec tests.

bundle exec rake guard starts a guard listener which watches files and auto-runs rspec to provide faster feedback

bundle exec rake lint will run rubocop
