Examples of F5 Distributed Cloud (XC) deployments utilizing Terraform. For more information on the use cases covered by this project, please see the following articles and workflow guides:
| DevCentral Overview Articles | Use Case / Workflow Guides (SaaS Console, Automation) |
|---|---|
| Deploy API Security on Regional Edges with F5 Distributed Cloud | Deploy F5 XC API Security on XC Regional Edges |
| Deploy API Security Anywhere with F5 Distributed Cloud | Deploy F5 XC API Security on XC Regional Edges + AppConnect |
| Deploy API Security Anywhere with F5 Distributed Cloud | Deploy F5 XC API Security on XC Customer Edges |
- F5 Distributed Cloud Account (F5XC)
- AWS Account - Due to the assets being created, free tier will not work.
- The F5 BIG-IP AMI being used from the AWS Marketplace must be subscribed to your account
- Please make sure resources like VPC and Elastic IP's are below the threshold limit in that aws region
- Terraform Cloud Account
- GitHub Account
Example: f5-xc-waf-on-re
Check the Automation section in your workflow guide for more details.
- xc: F5 Distributed Cloud WAAP
- infra: AWS Infrastructure (VPC, IGW, etc.)
- eks: AWS Elastic Kubernetes Service
- arcadia: Arcadia Finance test web application and API
- juiceshop: OWASP Juice Shop test web application
- Cloud Provider: AWS
- IAC: Terraform
- IAC State: Terraform Cloud
- CI/CD: GitHub Actions
- Workspaces: Create a CLI or API workspace for each asset in the workflow chosen. Check the Automation section in your workflow guide for more details
Example:
| Workflow | Assets/Workspaces |
|---|---|
| f5-xc-waf-on-re | infra, xc |
-
Workspace Sharing: Under the settings for each Workspace, set the Remote state sharing to share with each Workspace created.
-
Variable Set: Create a Variable Set with the following values:
Name Type Description AWS_ACCESS_KEY_ID Environment Your AWS Access Key ID AWS_SECRET_ACCESS_KEY Environment Your AWS Secret Access Key AWS_SESSION_TOKEN Environment Your AWS Session Token VOLT_API_P12_FILE Environment Your F5XC API certificate file name. Set this to api.p12 VES_P12_PASSWORD Environment Set this to the password you supplied when creating your F5 XC API certificate ssh_key Terraform Your ssh key for accessing the created BIG-IP and compute assets admin_src_addr Terraform The source address and subnet in CIDR format of your administrative workstation tf_cloud_organization Terraform Your Terraform Cloud Organization name
-
Fork and Clone Repo. Navigate to
Actionstab and enable it. -
Actions Secrets: Create the following GitHub Actions secrets in your forked repo
- P12: The linux base64 encoded F5XC API certificate
- TF_API_TOKEN: Your Terraform Cloud API token
- TF_CLOUD_ORGANIZATION: Your Terraform Cloud Organization name
- TF_CLOUD_WORKSPACE_<Workspace Name>: Create for each workspace in your workflow
- EX: TF_CLOUD_WORKSPACE_BIGIP_BASE would be created with the value
bigip-base
- EX: TF_CLOUD_WORKSPACE_BIGIP_BASE would be created with the value
STEP 1: Check out a branch for the workflow you wish to run using the following naming convention.
DEPLOY
| Workflow | Branch Name |
|---|---|
| f5-xc-waf-on-k8s | deploy-f5-xc-waf-on-k8s |
| f5-xc-waf-on-re | deploy-f5-xc-waf-on-re |
DESTROY
| Workflow | Branch Name |
|---|---|
| f5-xc-waf-on-k8s | destroy-f5-xc-waf-on-k8s |
| f5-xc-waf-on-re | destroy-f5-xc-waf-on-re |
STEP 2: Rename infra/terraform.tfvars.examples to infra/terraform.tfvars and add the following data:
- project_prefix = "Your project identifier name in lower case letters only - this will be applied as a prefix to all assets"
- resource_owner = "Your-name"
- aws_region = "AWS Region" ex. us-east-1
- azs = ["us-east-1a", "us-east1b"] - Change to Correct Availability Zones based on selected Region
- Also update assets boolean value as per your work-flow
Step 3: Rename xc/terraform.tfvars.examples to xc/terraform.tfvars and add the following data:
- api_url = "Your F5XC tenant"
- xc_tenant = "Your tenant id available in F5 XC
AdministrationsectionTenant Overviewmenu" - xc_namespace = "The existing XC namespace where you want to deploy resources"
- app_domain = "the FQDN of your app (cert will be autogenerated)"
- xc_waf_blocking = "Set to true to enable blocking"
STEP 4: Commit and push your build branch to your forked repo
- Build will run and can be monitored in the GitHub Actions tab and TF Cloud console
STEP 5: Once the pipeline completes, verify your assets were deployed or destroyed based on your workflow.
NOTE: The autocert process takes time. It may be 5 to 10 minutes before Let's Encrypt has provided the cert.
