Content-change pass following the extraction from the app monorepo (this repo
now stands alone, sourced via git filter-repo to preserve history):
- terraform/variables.tf, secrets.tf, modules/thermograph-host: remove every
app-secret Terraform variable (postgres_password, auth_secret, VAPID keys,
registry_token, Discord/SMTP creds, ...) and the random_password/random_id
generators. The SOPS+age vault (deploy/secrets/*.yaml) is now the sole
source of app secrets, rendered at deploy time by deploy/render-secrets.sh;
Terraform renders only a non-secret /etc/thermograph-topology.env (sizing,
routing) via the renamed thermograph-topology.env.tftpl template.
- hosts gains a required app_image_tag field: the host's own checkout is now
this infra repo, not the app repo, so there is no "current commit" to
derive an image tag from — every host pins one explicitly. repo_url now
points at this repo (private; typically needs an embedded read token).
- deploy.sh: IMAGE_TAG is now required from the environment instead of
derived via `git rev-parse HEAD` of the (now infra-repo) checkout, which
would have silently resolved to the wrong or a nonexistent tag.
- New terraform/modules/gcp-host: creates a GCE VM + minimal VPC/firewall
only, then feeds its IP into the same thermograph-host module every
SSH-managed host already uses — one provisioning path regardless of how a
host came to exist. var.gcp_hosts defaults to {}, so no google_* resource
is planned and the provider is never invoked without it (verified: plan
and validate succeed with no GCP credentials configured).
- terraform/README.md, ACCESS.md (renamed from INFRA.md), README.md: updated
for the new secrets model, the GCP scaffold, and this repo's own identity.
Verified: terraform fmt/validate/init clean; plan succeeds against realistic
dummy hosts (prod+beta shape) and against a populated gcp_hosts entry (plans
6 resources with no live credentials, confirming the composition wires
correctly end to end).
