Overview

A Terraform provider for F5 BigIP. Resources are currently available for LTM.

F5 Requirements

This provider uses the iControlREST API. Make sure that is installed and enabled on your F5 before proceeding.

Installation

• Download the latest release for your platform.
• Rename the executable to terraform-provider-bigip
• Copy somewhere on your path, or update .terraformrc in your home directory like so:

     log local0. "test"
   }
EOF
}

Reference

name - (Required) Name of the iRule

irule - (Required) Body of the iRule

bigip_ltm_virtual_address

Configures a Virtual Address. NOTE: create/delete are not implemented since the virtual addresses should be created/deleted automatically with the corresponding virtual server.

Example

resource "bigip_ltm_virtual_address" "vs_va" {

    name = "/Common/${bigip_ltm_virtual_server.vs.destination}"
    advertize_route = true

icmp_echo - (Optional, Default=true) Enable/Disable ICMP response to the virtual address

traffic_group - (Optional, Default=/Common/traffic-group-1) Specify the partition and traffic group

bigip_ltm_policy

Configure local traffic policies. This is a fairly low level resource that does little to make actually using policies any simpler. A solid understanding of how policies and their associated rules, actions and conditions are managed through iControlREST is recommended.

Example

resource "bigip_ltm_policy" "policy" {
  name = "/Common/my_policy"
  strategy = "/Common/first-match"
  requires = ["http"]
  controls = ["forwarding"]
  rule {
    name = "/Common/rule1"

    condition {
      httpUri = true
      startsWith = true
      values = ["/foo"]
    }

    condition {
      httpMethod = true
      values = ["GET"]
    }

    action {
      forward = true
      pool = "/Common/my_pool"
    }
  }
}

Reference

name - (Required) Name of the policy

strategy - (Required) Strategy selection when more than one rule matches.

requires - (Required) Defines the types of conditions that you can use when configuring a rule.

controls - (Required) Defines the types of actions that you can use when configuring a rule.

rule - defines a single rule to add to the policy. Multiple rules can be defined for a single policy.

Rules

Actions and Conditions support all fields available via the iControlREST API. You can see all of the available fields in the iControlREST API documentation. Each field in the actions and conditions objects is available. Pro tip: Create your policy via the GUI first then use the REST API to figure out how to configure the terraform resource.

name (Required) - Name of the rule

action - Defines a single action. Multiple actions can exist per rule.

condition - Defines a single condition. Multiple conditions can exist per rule.

Building

Create the distributable packages like so:

make get-deps && make bin && make dist

See these pages for more information:

• https://www.terraform.io/docs/internals/internal-plugins.html
• https://github.com/hashicorp/terraform#developing-terraform

Testing

Running the acceptance test suite requires an F5 to test against. Set BIGIP_HOST, BIGIP_USER and BIGIP_PASSWORD to a device to run the tests against. By default tests will use the Common partition for creating objects. You can change the partition by setting BIGIP_TEST_PARTITION.

BIGIP_HOST=f5.mycompany.com BIGIP_USER=foo BIGIP_PASSWORD=secret make testacc
