IBM Secure Landing Zone module

The landing zone module can be used to create a fully customizable VPC environment within a single region. The five following patterns are starting templates that can be used to get started quickly with Landing Zone. These patterns are located in the patterns directory.

Each of these patterns (except VSI QuickStart) creates the following infrastructure:

• A resource group for cloud services and for each VPC.
• Cloud Object Storage instances for flow logs and Activity Tracker
• Encryption keys in either a Key Protect or Hyper Protect Crypto Services instance
• A management and workload VPC connected by a transit gateway
• A flow log collector for each VPC
• All necessary networking rules to allow communication
• Virtual Private Endpoint (VPE) for Cloud Object Storage in each VPC
• A VPN gateway in the management VPC

Each pattern creates the following infrastructure on the VPC:

• The VPC pattern deploys a simple IBM Cloud VPC infrastructure without any compute resources like VSIs or Red Hat OpenShift clusters
• The QuickStart VSI pattern deploys edge VPC with one VSI and a jump server VSI in the management VPC
• The virtual server (VSI) pattern deploys identical virtual servers across the VSI subnet tier in each VPC
• The Red Hat OpenShift Kubernetes (ROKS) pattern deploys identical clusters across the VSI subnet tier in each VPC
• The mixed pattern provisions both of these elements
• Landing zone VPC CRNs can be added to an existing CBR (Context-based restrictions) network zone if the existing CBR zone ID is specified.

For more information about the default configuration, see Default Secure Landing Zone configuration.

terraform-ibm-landing-zone

Complete the following steps before you deploy the Secure Landing Zone module.

Set up an IBM Cloud Account

1. Make sure that you have an IBM Cloud Pay-As-You-Go or Subscription account:

   • If you don't have an IBM Cloud account, create one.
   • If you have a Trial or Lite account, upgrade your account.

Configure your IBM Cloud account for Secure Landing Zone

1. Log in to IBM Cloud with the IBMid you used to set up the account. This IBMid user is the account owner and has full IAM access.
2. Complete the company profile and contact information for the account. This profile is required to stay in compliance with IBM Cloud Financial Service profile.
3. Enable the Financial Services Validated option for your account.
4. Enable virtual routing and forwarding (VRF) and service endpoints by creating a support case. Follow the instructions in enabling VRF and service endpoints](https://cloud.ibm.com/docs/account?topic=account-vrf-service-endpoint&interface=ui#vrf).

Set up account access (Cloud IAM)

1. Create an IBM Cloud API key. The user who owns this key must have the Administrator role.

2. Require users in your account to use multifactor authentication (MFA).

3. Set up access groups. User access to IBM Cloud resources is controlled by using the access policies that are assigned to access groups. For IBM Cloud Financial Services validation, all IAM users must not be assigned direct access to any IBM Cloud resources.

   Select All Identity and Access enabled services when you assign access to the group.

(Optional) Set up IBM Cloud Hyper Protect Crypto Services

For Key Management services, you can use IBM Cloud Hyper Protect Crypto Services. Create an instance before you create the Secure Landing Zone.

1. Create the service instance:

   1. (Optional) Create a resource group for your instance.
   2. On the Hyper Protect Crypto Services (https://cloud.ibm.com/catalog/services/hyper-protect-crypto-services) details page, select a plan.
   3. Complete the required details that are required and click Create.

2. Initialize Hyper Protect Crypto Services:

   To initialize the provisioned Hyper Protect Crypto Service instance, follow the steps in Getting started with IBM Cloud Hyper Protect Crypto Services.

   For proof-of-technology environments, use the auto-init flag. For more information, see Initializing service instances using recovery crypto units.

Customize your environment

You can customize your environment with Secure Landing Zone in two ways: by using Terraform input variables or by using the override.json file.

Customizing by using Terraform input variables

In the first method, you set a couple of required input variables of your respective pattern, and then provision the environment.

You can find the list of input variables in the variables.tf file of the pattern directory:

• VPC pattern input variables
• VSI pattern input variables
• OCP pattern input variables
• Mixed pattern input variables

Terraform supports multiple ways to set input variables. For more information, see Input Variables in the Terraform language documentation.

For example, you can add more VPCs by adding the name of the new VPC to the vpcs variable in the variables.tf file in your patterns directory.

vpcs  = ["management", "workload", "<ADDITIONAL VPC>"]

You can get more specific after you use this method. Running the Terraform outputs a JSON-based file that you can use in override.json.

Customizing by using the override.json file

The second route is to use the override.json to create a fully customized environment based on the starting template. By default, each pattern's override.json is set to contain the default environment configuration. You can use the override.json in the respective pattern directory by setting the template input override variable to true. Each value in override.json corresponds directly to a variable value from this root module, which each pattern uses to create your environment.

Supported variables

Through the override.json, you can pass any variable or supported optional variable attributes from this root module, which each pattern uses to provision infrastructure. For a complete list of supported variables and attributes, see the variables.tf file.

ℹ️ Tip: You can use the landing zone configuration tool to create the JSON.

Overriding variables

After every execution of terraform apply, a JSON-encoded definition is output. This definition of your environment is based on the defaults for the Landing Zone and any variables that are changed in the override.json file. You can then use the output in the override.json file.

You can redirect the contents between the output lines by running the following commands:

config = <<EOT
EOT

After you replace the contents of the override.json file with your configuration, you can edit the resources within. Make use that you set the template override variable to true as an input variable. For example, within the variables.tf file.

Locally run configurations do not require a Terraform apply command to generate the override.json. To view your current configuration, run the terraform refresh command.

Overriding only some variables

The override.json file does not need to contain all elements. For example,

{
  "enable_transit_gateway": false
}

(Optional) F5 BIG-IP

The F5 BIG-IP Virtual Edition supports setting up a client-to-site full tunnel VPN to connect to your management or edge VPC or a web application firewall (WAF). With this configuration, you can connect to your workload VPC over the public internet.

Through Secure Landing Zone, you can optionally provision the F5 BIG-IP so that you can set up the implemented solution of a client-to-site VPN or web application firewall (WAF). For more information, see Provisioning a F5 BIG-IP host by using Secure Landing Zone.

(Optional) Bastion host by using Teleport

With Teleport, you can configure a virtual server instance in a VPC as a bastion host. Some of Teleport features include single sign-on to access the SSH server, auditing, and recording of your interactive sessions. For more information about Teleport, see the Teleport documentation.

Secure Landing Zone can set up a bastion host that uses Teleport. For more information, see Provisioning a bastion host by using Teleport with Secure Landing Zone.

Details about the Secure Landing Zone module

VPC

This template supports creating any number of VPCs in a single region. The VPC network and components are created by the Secure Landing Zone VPC module. The VPC components are described in the main.tf file.

vpcs variable

The list of VPCs from the vpcs variable is converted to a map, which supports adding and deleting resources without the need for an update. The VPC network includes the following aspects:

• VPC
• Subnets
• Network ACLs
• Public gateways
• VPN gateway and gateway connections

The following example shows the vpc variable type.

Flow logs

You can add flow log collectors to a VPC by adding the flow_logs_bucket_name parameter to the vpc object. You declare each bucket in the cos variable that manages Cloud Object Storage. For more information about provisioning Cloud Object Storage with this template, see the Cloud Object Storage section.

Transit gateway

You can create a transit gateway that connects any number of VPCs in the same network by setting the enable_transit_gateway variable to true. A connection is created for each VPC that you specify in the transit_gateway_connections variable. You configure the transit gateway resource in the transit_gateway.tf file.

Security groups

You can provision multiple security groups within any of the provisioned VPCs. You configure security group components in the security_groups.tf file.

security_group variable

The security_group variable supports creating security groups dynamically. The list of groups is converted to a map to ensure that changes, updates, and deletions don't affect other resources.

The following example shows the security_group variable type.

  list(
    object({
      name     = string # Name for each security group
      vpc_name = string # The group will be created. Only VPCs from `var.vpc` can be used

          source    = string # Source CIDR to allow

          ##############################################################################
          # Optionally, security groups can allow ONE of the following blocks
          # additional rules will have to be created for different types of traffic

          tcp = optional(
            object({
              port_max = number
              port_min = number
            })
          )
          udp = optional(
            object({
              port_max = number
              port_min = number
            })
          )
          icmp = optional(
            object({
              type = number
              code = number

Virtual servers

This module uses the Cloud Schematics VSI Module to support multiple VSI workloads. The VSI submodule covers the following resources:

• Virtual server instances
• Block storage for those instances
• VPC load balancers for those instances

Virtual server components can be found in virtual_servers.tf

VPC SSH keys

You can use this template to create or return multiple VPC SSH keys by using the ssh_keys variable. For more information about how to locate an SSH key or create one, see SSH keys in the IBM Cloud docs.

ssh_keys variable

Users can add a name and optionally a public key. If public_key is not provided, the SSH key is retrieved by using a data block

  type = list(
    object({
      name           = string
      public_key     = optional(string)
      resource_group = optional(string) # Must be in var.resource_groups
    })
  )

vsi variable

ℹ️ Tip: After the infrastructure is created, changes to the vsi variable won't change the VSI image. The restriction is in place so that you don't inadvertently create an outage or lose data.

The following example shows the vsi virtual server variable type.

list(
    object({
      name            = string                  # Name to be used for each VSI created

(Optional) Bastion host

You can provision a bastion host that uses Teleport. App ID is used to authenticate users to Teleport. Teleport session recordings are stored in a Cloud Object Storage bucket. You configure the bastion host components in the bastion_host.tf file.

App ID variable

To use the bastion host, either create an App ID instance or use an existing one. If the use_data variable is set to true, an existing App ID instance is used. Set the variable to false create an App ID instance.

object(
  {
    name                = optional(string)         # Name of existing or to be created APP ID instance
    resource_group      = optional(string)         # The resource group of the existing or to be created APP ID instance
    use_data            = optional(bool)           # Bool specifying to use existing or to be created APP ID instance
    keys                = optional(list(string))   # List of App ID resource keys
    use_appid           = bool                     # Bool specifying to connect App ID to bastion host or not
  }
)

Teleport config data variable

The teleport_config block creates a single template for all teleport instances. By using a single template, the values remain hidden.

object(
  {
    teleport_license   = optional(string) # The PEM license file
    https_cert         = optional(string) # The https certificate used by bastion host for teleport

Cluster and worker pool

You can create as many iks or openshift clusters and worker pools on VPC. For ROKS clusters, make sure to enable public gateways to allow your cluster to correctly provision ingress application load balancers.

❗ Important: You can't update Red Hat OpenShift cluster nodes by using this module. The Terraform logic ignores updates to prevent possible destructive changes.

The following example shows the cluster variable type.

Virtual private endpoints

Virtual private endpoints can be created for any number of services. Virtual private endpoint components are defined in the vpe.tf file.

IBM Cloud services

You can configure the following IBM Cloud services from this module.

Cloud Object Storage

This module can provision a Cloud Object Storage instance or retrieve an existing one, and then create any number of buckets within the instance.

You define Cloud Object Storage components in the cos.tf file.

VPC placement groups

You can create multiple VPC placement groups in the vpc_placement_groups.tf file. For more information about VPC placement groups, see About placement groups in the IBM Cloud Docs.

Usage

Template for multiple patterns

You can use the modular design of this module to provision architectures for VSI, clusters, or a combination of both. Include a provider block and a copy of the variables.tf file. By referencing this template as a module, you support users who want to add clusters or a vsi by adding the relevant variable block.

wait_till	To avoid long wait times when you run your Terraform code, you can specify the stage when you want Terraform to mark the cluster resource creation as completed. Depending on what stage you choose, the cluster creation might not be fully completed and continues to run in the background. However, your Terraform code can continue to run without waiting for the cluster to be fully created. Supported args are MasterNodeReady, OneWorkerNodeReady, and IngressReady	string	"IngressReady"	no
