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' # this is optional; defaults to :manual so won't touch your setting # unless you specify one of the valid options. snat_pool :automap 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.
Managing virtual server client and server ssl profiles
The f5_vip
resource exposes a pair or properties which allow you to add client and server SSL profiles to a virtual server.
f5_vip 'myvip' do address 'vipaddress' port 'vipport' protocol 'protocol' # TCP default pool 'mypool' client_ssl_profile 'client.cert' server_ssl_profile 'server.cert' end
These two properties are optional and only take effect if they are specified.
They will converge to ensure that profile is applied to the given vip, but there is currently no option to remove an SSL profile.
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
