Configure Terraform

The set of files used to describe infrastructure in Terraform is known as a Terraform configuration. To read about the syntax of the configuration files, see this documentation.

F5 recommends the following:

  • Only using JSON when the configuration is generated by a machine.

  • Using a standalone machine or VM where Terraform is installed for configuration.

  • If using Terraform Cloud, set up a proper RBAC to protect the F5 BIG-IP credentials.

The following example presents the entire configuration with descriptions for each section. Save the example contents in a file named,


Verify that there are no other *.tf files in your directory, since Terraform loads all of them.

Sample Terraform resource

The following sample demonstrates creating a policy on the F5 BIG-IP system:

provider "bigip" {
    address = "x.x.x.x"
    username = "xxxx"
    password = "xxxx"

resource "bigip_ltm_policy" "test-policy" {
    name = "/Common/test-policy"
    strategy = "first-match"
    requires = ["http"]
    controls = ["forwarding"]
    rule {
        name = "rule6"
        action {
            tm_name = "20"
            forward = true
            pool = "/Common/mypool"
    depends_on = [bigip_ltm_pool.mypool]

resource "bigip_ltm_pool" "mypool" {
    name = "/Common/mypool"
    monitors = ["/Common/http"]
    allow_nat = "yes"
    allow_snat = "yes"
    load_balancing_mode = "round-robin"

The provider block is used to configure the named provider, in this case “bigip”. A provider is responsible for creating and managing resources. Multiple provider blocks can exist, if a Terraform configuration is composed of multiple providers, which is a common situation.

The resource block defines a resource that exists within the infrastructure. The resource block has two strings before opening the block:

  • Resource type

  • Resource name

In this example, the resource type is bigip_ltm_policy and the name is test-policy. The prefix of the type, maps to the provider. In this case bigip_ltm_policy automatically tells Terraform that it is managed by the bigip provider.

Argument reference

The following table provides parameter descriptions for the bigip_ltm_policy resource:






Describes the name of the policy.



This value specifies the match strategy.



Descriptive text that identifies the LTM policy.



This value specifies the protocol.



Currently, the resource automatically publishes the policy. Previously, this value determined whether to publish the policy, otherwise deploy it in Drafts mode.



This value specifies the controls.



Use this policy to apply rules.



If Rule is used, then you need to provide the tm_name. It can be any value.



This action sets forwarding.



This action will direct the stream to this pool.



This action is set to true by default. You must explicitly set to false for actions with which it conflicts.

SSL key certificate

Provides details about bigip_ssl_key_cert resource and imports SSL certificate and key on BIG-IP LTM. Import the certificate and the key from files on the local disk, in PEM format.

resource "bigip_ssl_key_cert" "testkeycert" {
  partition   = "Common"
  key_name    = "ssl-test-key"
  key_content = file("key.pem")
  cert_name    = "ssl-test-cert"
  cert_content = file("certificate.pem")

Parameter reference

The following table provides argument and attribute descriptions for the bigip_ssl_key_cert resource:






Argument string type naming the SSL key that you want imported onto the BIG-IP.



Argument with the content of the SSL key on local disk. The path of SSL key is provided to the Terraform file function.



Argument string type, name the SSL certificate you want imported onto the BIG-IP.



Argument with the content of the certificate on local disk. The path of SSL certificate is provided to the Terraform file function.



Argument string type identifying the partition on to the SSL certificate and the key you want imported.



Argument string type identifying the passphrase on the SSL key.



Argument string specifying the type of monitoring used.



Argument string specifying the issuer certificate.



Argument string specifying the online certificate status protocol (OCSP) responder coming from the issuer.



Attribute exported identifier of the resource.



Attribute exported full path of the SSL key on the BIG-IP.



Attribute exported full path of the SSL certificate on the BIG-IP.


The first command to run for a new configuration, or after checking out an existing configuration from version control, is terraform init, which initializes local settings and data used by subsequent commands.

Terraform uses a plugin-based architecture to support available infrastructure and service providers. As of Terraform version 0.10.0, each “Provider” is its own encapsulated binary distributed separately from Terraform itself. The terraform init command will automatically download and install any Provider binary for the providers in use within the configuration, which in this case is just the BIG-IP provider:

$ terraform init

 Initializing the backend...

 Initializing provider plugins...

 Terraform has been successfully initialized!

You can begin working with Terraform. To see changes that are required for your infrastructure, run the command terraform plan. All Terraform commands will now execute.

If you ever set or change resources or the backend configuration for Terraform, rerun this command to reinitialize your working directory. If you forget, other commands will detect it and remind you to do so (if necessary).

Applying changes

The commands shown in this guide apply to Terraform 0.11 and later. To see the execution plan before applying it, you must run the terraform plan command in versions earlier than Terraform 0.11. Use terraform version to confirm your running version.

  1. In the same directory as the file you created, run terraform apply.

    The following output shows the execution plan and describes which actions Terraform will take in order to change real infrastructure to match the configuration. The output format is similar to the diff format generated by tools such as Git. The output has a + next to bigip_ltm_policy.test-policy, meaning that Terraform will create this resource. Beneath that, the output displays the attributes to be set. When the value displayed is (known after apply), it means that you will not know the value until the resource is created.

    $ terraform apply
    An execution plan has been generated and is shown below.
    Resource actions are indicated with the following symbols:
    + create
    Terraform will perform the following actions:
      # bigip_ltm_policy.test-policy will be created
      + resource "bigip_ltm_policy" "test-policy" {
          + controls = [

    Plan: 2 to add, 0 to change, 0 to destroy.
    Do you want to perform these actions?
      Terraform will perform the actions described above.
      Only 'yes' will be accepted to approve.
      Enter a value: yes
    bigip_ltm_pool.mypool: Creating...
    bigip_ltm_pool.mypool: Creation complete after 0s [id=/Common/mypool]
    bigip_ltm_policy.test-policy: Creating...
    bigip_ltm_policy.test-policy: Creation complete after 0s [id=test-policy]
    Apply complete! Resources: 2 added, 0 changed, 0 destroyed.
  2. OPTIONAL: At this stage, if terraform apply failed with an error, it is likely a syntax error in the configuration. Fix any errors.

  3. If the plan was created successfully, Terraform will now pause and wait for approval before proceeding. If anything in the plan seems incorrect or dangerous, it is safe to exit at this step with no changes made to your infrastructure. If the plan looks acceptable, at the confirmation prompt to proceed, type yes.

  4. Verify the new policy created by Terraform in BIG-IP.

    Terraform also writes data into the terraform.tfstate file. This state file is important; it keeps track of the IDs of created resources so that Terraform knows what it is managing. You must save this file and distribute it to anyone running Terraform. F5 recommends that you setup remote state when working with Terraform. Doing so shares the state automatically; however, this is NOT required for simple situations like in this Configuration Guide.

  5. Inspect the current state using, terraform show:

    $ terraform show
    # bigip_ltm_policy.test-policy:
    resource "bigip_ltm_policy" "test-policy" {
        controls = [

Generating a BIG-IP Provider binary

Do the following to build a Terraform BIG-IP provider binary:


To build locally

  1. git clone

  2. cd terraform-provider-bigip

  3. export GOFLAGS=-mod=vendor

  4. go build

  5. Move the binary to the current working directory where Terraform config files are located.
