+# Plan: Implement ACME Challenge LB Rules for Bestnet
+
+We will add OpenStack Load Balancer resources to `nomadclient.tf` to handle ACME challenges, creating a dedicated pool and L7 rules to redirect `.well-known/acme-challenge/` traffic. A new variable will be introduced to handle the port difference between environments (8081 default, 8080 for prod-bestnet).
+
+## Proposed Changes
+
+### 1. Modify `nomadclient.tf`
+- Add `variable "nomadclient_acme_port"` with a default value of `8081`.
+- Add the following resources (adapted from the ticket snippet):
+  - `openstack_lb_pool_v2.nomadclient_challenge_acme`
+  - `openstack_lb_member_v2.nomadclient_challenge_acme` (using `var.nomadclient_acme_port`)
+  - `openstack_lb_monitor_v2.acme_healthmonitor`
+  - `openstack_lb_l7policy_v2.acme_challenge_policy`
+  - `openstack_lb_l7rule_v2.acme_challenge_rule`
+
+### 2. Modify `environments/prod-bestnet.tfvars`
+- Add `nomadclient_acme_port = 8080` to override the default for the production environment, aligning with the ticket's note.
+
+## Rationale
+- The ticket explicitly provides the Terraform configuration needed to support the new Vault-based Let's Encrypt integration.
+- The comment "in prod_bestnet protocol_port = 8080" indicates a deviation from the snippet's 8081 for the production environment. Using a variable allows us to apply the standard configuration while respecting the environment-specific requirement.
+- Existing `nomadclient` resources in `nomadclient.tf` confirm the resource names match the snippet (e.g., `openstack_compute_instance_v2.nomadclient`).
+
+## Verification
+- Verify that `nomadclient.tf` successfully validates.
+- Ensure `prod-bestnet.tfvars` correctly overrides the port.

+# Plan: Create Terragrunt Example Configurations
+
+We will add and organize Terragrunt example configurations to illustrate how to consume the existing Terraform modules in a consistent, reusable way. Examples will live under a dedicated `examples/` hierarchy, with clear documentation of required inputs, outputs, and common usage patterns.
+
+## Proposed Changes
+
+### 1. Add base Terragrunt example structure
+- Create an `examples/` directory (if it does not already exist).
+- Under `examples/`, add one or more subdirectories (for example, `examples/simple-environment/`, `examples/production-like/`) to hold self-contained Terragrunt configurations.
+- In each example directory, add a `terragrunt.hcl` that:
+  - References the appropriate Terraform module using `terraform { source = ... }`.
+  - Defines `inputs` for all required module variables, using simple, realistic example values.
+  - Optionally demonstrates use of Terragrunt features such as `include`, `locals`, and `dependency` where helpful but without adding unnecessary complexity.
+
+### 2. Document how to use the examples
+- Add a short `README.md` in the `examples/` directory that:
+  - Lists the available example configurations and their purpose.
+  - Shows how to run an example end-to-end with `terragrunt init` and `terragrunt apply`.
+  - Notes any assumptions (e.g., required environment variables, backend configuration, or credentials) needed to run the examples.
+
+### 3. Keep examples read-only and non-destructive by default
+- Ensure example configurations are safe to run in a typical developer environment:
+  - Use minimal, low-cost resources where possible.
+  - Clearly mark any examples that may create billable or irreversible infrastructure.
+  - Where appropriate, configure examples so they can be destroyed cleanly with `terragrunt destroy`.
+
+## Rationale
+- The purpose of this work is to provide Terragrunt example configurations, so the plan must focus on adding and documenting those examples rather than unrelated infrastructure changes.
+- Centralizing examples under `examples/` makes it easier for users to discover, run, and learn from them without impacting production configurations.
+- Well-documented examples reduce onboarding time and help ensure modules are used consistently across environments.
+
+## Verification
+- From each example directory, run `terragrunt init` to verify the configuration initializes successfully.
+- Run `terragrunt plan` to confirm that the examples reference the correct Terraform modules and that all required inputs are provided.
+- Optionally run `terragrunt apply` in a non-production account or environment to confirm the examples work as documented and can be destroyed cleanly with `terragrunt destroy`.
