Job terraform-module-one-resource-set-reviewed-plan · revised 11 October 2026
Write one Terraform module for a defined resource set, with the plan reviewed
One defined set of cloud resources is written as a reusable Terraform module with named inputs and outputs, and a plan against a test account is reviewed line by line before you apply anything.
You might be seeing
- The same resources were clicked together in a console more than once, with small differences
- Nobody can recreate the staging environment from a description
- A resource was changed by hand and nobody knows what it looked like before
No passwords, keys, card details or admin invites needed to start.
What usually happened
Resources made by hand cannot be reviewed, repeated or compared. Writing them as Terraform helps only if the module has sensible inputs and outputs, does not wrap a single resource without adding anything, keeps secrets out of version control, and is judged by reading the plan, because the plan is what will happen. Terraform state can hold sensitive values in plain text, and a saved plan file can too.
Who it’s for: A founder or small engineering team that creates the same few cloud resources by hand in a console, or copies configuration between environments, and wants them described in code.
Usually starts when: A second environment is needed, a console change broke something nobody can reproduce, or a new engineer asks how the infrastructure was built.
The result: One defined resource set, up to eight resource types in one provider, is written as a Terraform module with documented inputs and outputs. We run a plan against a test account or a clean state and review it with you line by line; it shows exactly the intended creates and no unexpected change or destroy. You receive the module, the plan review notes and the apply and destroy steps, and you run the apply and the destroy yourself.
Check whether this job fits
Four checks that decide whether this fixed job fits. Your answers stay on this page unless you choose to email them.
Checks you can run yourself
Check your Terraform version
Run on the machine that would apply the changes. It only prints versions.
terraform versionLook for: The Terraform version and the providers already in use. Send these; they decide which language features we can rely on.
What you get
- The module and the example configuration, with version constraints for Terraform and the provider
- The plan output with reviewer notes explaining each create, change and destroy
- A list of values that would appear in state or plan files, and the apply, destroy and revert steps
Included
- One resource set in one provider, up to eight resource types, such as a network, a server and a database, or a bucket with its access policy
- A module with input variables, outputs and a README, and one example root configuration that calls it
- Remote state with locking recommended for your backend, and a note on what sensitive values the state would hold
- A plan run by us against a test account or clean state with a plan-only credential, a written plan review, and the apply and destroy steps that you run yourself, with your written approval before each
Not included
- Importing existing production resources into state, or adopting a live environment: that is a larger, separate piece of work
- Running apply or destroy in any account, or holding your production credentials
- Multiple providers, multiple regions or a module registry
- CI pipelines that run Terraform
- Security, cost or compliance review of the cloud account
How we know it’s done
Agreed with you before work starts. Each check produces evidence you keep.
The module passes Terraform's validation and formatting checks, and the example configuration initialises with the pinned provider version.
Evidence: The output of the validate and format checks and the initialisation log.
terraform fmt -check && terraform validateA plan against the test account shows only the creates listed in the resource inventory, and no unexpected change, replace or destroy.
Evidence: The plan output with a table matching each planned create to an item in the inventory.
Every input and output has a description, every input without a safe default is required, and no input default or output contains a secret.
Evidence: The reviewer's variable and output checklist.
After you have applied in the test account, a second plan run by us shows no changes, and the destroy plan you ran before the destroy listed only the resources the module created.
Evidence: The post-apply plan result (exit code 0 with the detailed exit code option), your written approvals, the destroy plan listing and the destroy result you send.
terraform plan -detailed-exitcodeThe handover lists every value that would appear in state and plan files and where the state is stored.
Evidence: The sensitive-values list and the backend description.
Sign-off. You sign off after reading the plan with the reviewer, running the apply in the test account yourself, seeing our post-apply plan with no changes, and accepting the apply and destroy steps. Payment follows sign-off.
If it fails. If the plan shows changes that cannot be explained or removed within the scope, you do not pay for this fixed scope and you keep the module and the plan notes. If the resource set needs an import of live resources, we stop and quote that separately.
When it fits, and when we stop
It fits when
- You can describe the resource set, or point to the console screens or an existing diagram
- You provide a test account, a sandbox project or an agreed clean state in which a plan can be produced, and a credential that you create, that is limited to what a plan needs and cannot create or destroy resources
- The provider has a maintained Terraform provider and the resource types are supported
- A person on your side reviews the plan, approves each apply and destroy in writing, and runs them in the test account with your own credentials
We stop and tell you if
- The task is mainly to bring existing production resources under Terraform without recreating them
- The plan would need real production credentials or real customer data
- The resources include things that a plan cannot safely describe, such as manually created state with no way to see its settings
- The provider or a required resource type is not supported by a maintained provider
What could go wrong
Nothing changes in your accounts until you apply. After an apply in a test account, the destroy steps you run remove what the module created, after you have read a destroy plan that lists only those resources. For production, the steps require the plan to be re-run and re-reviewed immediately before the apply, because state, provider versions or inputs can change between review and apply; the handover records the plan we reviewed so the effect of a later apply can be compared with it.
Scroll the table sideways to read it all.
| Risk | How we handle it |
|---|---|
| A plan that looks like a small change replaces or destroys a resource that holds data. | Review every replacement in the plan, mark data-bearing resources so a plan that would destroy them fails, and record that this protection disappears if the resource block is removed. |
| State or a saved plan file exposes a password or token. | Recommend a remote backend with encryption and access control, treat plan files as sensitive, and list the values the state would hold. A sensitive marking hides values in output but does not keep them out of state. |
| The plan used a narrow test setup that hides a difference in production. | State what was and was not represented in the test account, and list the inputs production will change. |
| An apply or destroy in the test account removes or changes something it should not. | You run both yourself after reading the exact plan, with a destroy plan that lists only the resources the module created, and the credential we use cannot create or destroy. |
An independent reviewer reads the plan output for unintended destroys, replacements and public exposure, and checks the module for secrets in variables, outputs and defaults.
How we deliver
We arrange the work and independent review, then show you the result against the agreed checks. You keep authority over your systems.
- Agree the resource set, the provider, the inputs that vary, the test account and who approves in writing
- Write the module with typed variables, outputs, version constraints and a README
- Run a plan in the test account with the plan-only credential and read every line of it, recording each create, change and destroy
- Independent review of the plan, of anything sensitive in state or plan files, and of prevent-destroy and lifecycle settings
- Hand over the module, the plan review notes and the apply and destroy steps
- You approve the exact plan in writing and run the apply in the test account; we re-run the plan, which should show no changes
- After a plan that shows only the test resources, you approve the destroy in writing and run it; for production, the steps say to re-run and re-review the plan immediately before any apply and name who may approve it
This is a one-off job, not emergency cover or a subscription. We confirm eligibility, the total price, a start window and a delivery date before you accept. Work starts only after agreed inputs, secure access, any licences and necessary permissions are in place. Hosting, platform and supplier charges are excluded unless the written quote includes them. No charge or booking is created by an enquiry.
Need to keep it working?
To have the configuration checked for drift every month, ask about the monthly Terraform drift review. This job writes and reviews the module once.
Ongoing work is separately scoped and quoted: no monitoring, response-time guarantee or automatic subscription is included in this job.

Other ways to get this done
- HashiCorp documents module design, including avoiding a module that only wraps one resource, which a team can use to structure its own code. developer.hashicorp.com
- If you only need one resource, writing it directly without a module is simpler and HashiCorp recommends it.
Questions
Will you apply it to my production account?
No. We run only a plan, in a test account, and review it with you. You run the apply and the destroy in the test account yourself, and any production apply with your own credentials.
Can you bring my existing infrastructure under Terraform?
Not in this fixed scope. That means importing live resources and reaching a plan with no changes, which is quoted separately.
Do you need my cloud credentials?
Only a least-privilege credential for a test account, created by you and revoked afterwards, that can run a plan but cannot create or destroy. Never production credentials.
Why review the plan line by line?
The plan is what will happen to your resources. A module that is easy to read can still plan a replacement of something that holds data.
Send an enquiry
Send us
- The provider and a list of the resource types with their purposes
- What should differ between environments, which become the module's inputs
- Whether you already use Terraform and which backend holds the state
- Do not send cloud credentials, access keys or state files in the first enquiry
Later, once you agree
- A test account or sandbox, and a plan-only credential for it that you create and revoke
- Any naming, tagging and region rules
- The reviewer on your side who will read the plan, approve in writing and run the apply and destroy in the test account
- A company-controlled secure handoff agreed before access: no live passwords, keys, private code or customer records by ordinary email.
You own the cloud accounts, the credentials and the state. We write the module and run terraform plan only, in a test account, with a credential that you create and revoke, that can read what a plan needs and cannot create or destroy resources. You run apply and destroy in the test account yourself, with your own credentials and only after your written approval of the exact plan, and send us the output. We never run apply or destroy in any account and never hold production credentials. A plan takes a state lock by default, so the credential also needs access to the state of the test account. We treat any saved plan file as sensitive.
