Some checks failed
Deploy dev content / Deploy shoc-frontend-new-dev through Terraform (push) Has been cancelled
* ci(cd): convert SPA hosting to handbook HCP and GitHub content CD Give HCP the bucket and CloudFront with an empty origin path. GitHub owns bucket-root sync and invalidation so merge-to-main and a human staging tag can deploy without creating HCP runs. G13 fails PRs that mix terraform/ with deployable application files. * ci: run Frontend checks and Terraform CI on PRs to main and dev Match backend 148 so a PR targeting origin/dev still gets the required checks. Push remains main only. * refactor(terraform): keep live/dev and live/staging as HCP roots Leave the adopted working directories in place so this CD PR does not retarget two live HCP workspaces. Flattening stays a later change. * style: prettier terraform-validate.mjs * fix(terraform): pin githubdeploy assume-role policy in import checker Reject controlled role updates whose trust document is not the rendered GitHub OIDC policy, matching the bucket-policy pin.

# Frontend Terraform (SPA CD)
|
|
|
|
`terraform/live/dev` and `terraform/live/staging` in AWS account `396287094661`.
|
|
HCP Terraform owns the bucket, CloudFront, DNS, and the GitHub deploy role.
|
|
GitHub Actions owns content: `.github/workflows/deploy-web.yaml` syncs `dist/`
|
|
to the bucket root and invalidates `/*`.
|
|
|
|
Creating, formatting, initializing with `-backend=false`, and validating these
|
|
files does not authorize an AWS, HCP Terraform, GitHub, or deployment
|
|
mutation. Live cutover waits for an explicit greenlight.
|
|
|
|
Do not collapse these roots into one `terraform/` tree in this PR. Flattening
|
|
retargets two live HCP working directories and is its own change.
|
|
|
|
## Fixed targets
|
|
|
|
| | dev | staging |
|
|
| ------------- | ------------------------------------ | ---------------------------------------- |
|
|
| Site | `dev.seahaven.com` | `staging.seahaven.com` |
|
|
| Bucket | `seahaven-shoc-frontend-dev` | `seahaven-shoc-frontend-staging` |
|
|
| Distribution | `E2CWLM1AFB964P` | `E2JDVEZ6EGD49J` |
|
|
| Deploy role | `githubdeploy-shoc-frontend-new-dev` | `githubdeploy-shoc-frontend-new-staging` |
|
|
| HCP workspace | `shoc-frontend-new-dev` | `shoc-frontend-new-staging` |
|
|
| Working dir | `terraform/live/dev` | `terraform/live/staging` |
|
|
|
|
There is no prod CloudFront in this round. Do not create
|
|
`shoc-frontend-new-prod`.
|
|
|
|
## Ownership
|
|
|
|
`module.environment_owned` keeps the same addresses as the adopted HCP
|
|
`shoc-frontend-new-dev` state. The SPA origin path is empty. The release
|
|
pointer is forgotten (`removed { destroy = false }`), not destroyed.
|
|
|
|
Deploy parameters live under `/shoc-frontend-new/<env>/deploy/{bucket,distribution-id}`.
|
|
`githubdeploy` may List/Get/Put/Delete the bucket root, CreateInvalidation, and
|
|
GetParameter on those two names. OIDC trust is `environment:<env>` plus
|
|
`job_workflow_ref` for `.github/workflows/deploy-web.yaml` at `refs/heads/main`
|
|
and `refs/tags/v*`.
|
|
|
|
`adoption_complete` is pinned in each live root. It is not a workspace
|
|
variable.
|
|
|
|
## Local checks (no apply)
|
|
|
|
```bash
|
|
terraform fmt -check -recursive terraform
|
|
terraform -chdir=terraform/live/dev init -backend=false -lockfile=readonly
|
|
terraform -chdir=terraform/live/dev validate
|
|
terraform -chdir=terraform/live/staging init -backend=false -lockfile=readonly
|
|
terraform -chdir=terraform/live/staging validate
|
|
python3 scripts/test-terraform-import-plan-check.py
|
|
python3 scripts/test_check_app_terraform_isolation.py
|
|
bash scripts/test-verify-cloudfront-release.sh
|
|
```
|
|
|
|
PRs cannot mix `terraform/` with deployable application files. Workflow, docs,
|
|
and gate-script changes may travel with either side. G13 is
|
|
`python3 scripts/check_app_terraform_isolation.py` against the PR base.
|
|
|
|
`npm run test:terraform` and `npm run verify` wrap the same gates. They never
|
|
create an HCP run or touch AWS.
|
|
|
|
## Cutover (greenlight only)
|
|
|
|
1. Keep HCP working directories `terraform/live/dev` and
|
|
`terraform/live/staging`. Dev VCS branch `main`. Staging tag regex
|
|
`^v[0-9]+\.[0-9]+\.[0-9]+-staging$`.
|
|
2. Auto-apply off. Apply the origin-path move for **dev** before any
|
|
`--delete` root sync.
|
|
3. Create GitHub Environment `dev` (staging already exists). Set
|
|
`DEPLOY_ROLE_ARN` on each.
|
|
4. Enable `deploy-web.yaml`. Then retire `deploy.yml`, `TF_API_TOKEN`, and
|
|
`TERRAFORM_CONTENT_CD_ENABLED`.
