Deploying the control plane

Two apps — apps/api and apps/auth — and two ways to run each of them. There is one handler per app and it is the same handler both ways: a function from a request to a response, holding no opinion about what is calling it.

Cloudflare Workers, via wrangler	what production and sandbox are today
A container, via the Dockerfile in each app	what a self-hoster runs, and where this is going

Settings arrive as bindings in the first case and as environment variables in the second, and @nestri/core's Env resolves the two into one shape — so HYPERDRIVE and DATABASE_URL are two spellings of the database, and an AUTH service binding and AUTH_INTERNAL_URL are two spellings of the route to the issuer. Nothing in either app branches on which it got.

Hostnames, and why they are shaped the way they are: dns.md.

Locally

Three ways, in increasing order of how much they resemble a deployment.

docker compose up postgres    # the database, for either of the next two
bun dev                       # both apps under the Workers runtime
bun run dev:server            # both apps as plain processes
docker compose up --build     # both apps as containers, plus the database

bun dev runs two wrangler dev sessions, on ports 1337 and 3000. They find each other through wrangler's local registry, so the API reaches the issuer over the same service binding it uses in production rather than over the network — which is the point of running it this way. Neither needs a Cloudflare account: the Hyperdrive binding falls back to localConnectionString, which is the compose database.

Settings that exist only locally live in apps/auth/.dev.vars rather than in vars. wrangler dev reads that file and wrangler deploy cannot upload it, which is the guarantee wanted for the one setting in it — the one that prints sign-in codes to the log.

docker compose here is Docker's plugin or podman-compose; both read the file unchanged.

Migrations are never run for you, in any of the three:

bun run db:migrate            # against DATABASE_URL

Cloudflare Workers

Configuration is apps/auth/wrangler.jsonc and apps/api/wrangler.jsonc. Each has two named environments, sandbox and production, plus an unnamed default that is the local one.

Wrangler's named environments do not inherit bindings from the top level — vars, services and hyperdrive are repeated in each on purpose, and a setting added to one environment and not the other is a silent hole rather than an error.

One-time setup

bunx wrangler login

# Once per database. Prints an id; paste it into both wrangler.jsonc files,
# replacing the placeholder for that environment.
bunx wrangler hyperdrive create nestri-production --connection-string "postgres://…"
bunx wrangler hyperdrive create nestri-sandbox    --connection-string "postgres://…"

Hyperdrive is a connection pool in front of Postgres, and it is there because each Worker isolate would otherwise open a connection of its own — which Postgres answers, at some point in a busy hour, with "sorry, too many clients already". A container has one pool per process and needs none of this.

Secrets

Set per app and per environment, and held by Cloudflare rather than by this repository:

cd apps/auth
bunx wrangler secret put EMAIL_SEND_URL --env production
bunx wrangler secret put EMAIL_API_KEY  --env production
bunx wrangler secret put EMAIL_FROM     --env production

cd ../api
bunx wrangler secret put STEAM_API_KEY       --env production
bunx wrangler secret put ADMIN_SHARED_SECRET --env production

The issuer refuses to send a sign-in code with its mail settings half configured or absent, rather than falling back to printing codes to the log — so a deployment that forgets these fails at the first sign-in attempt with a message naming what is missing, instead of quietly logging usable codes.

Deploying

bun run deploy:sandbox
bun run deploy:production

Both deploy the issuer first and the API second, because the API's AUTH binding names a script that has to exist. The custom domains in the config are what create the DNS records — there is no separate step, and no separate tool holding the other half of that fact.

Containers

docker build -f apps/api/Dockerfile  -t nestri-api  .
docker build -f apps/auth/Dockerfile -t nestri-auth .

The context is the repository root in both cases: the lockfile and the two shared packages are there, and a context rooted at the app directory could not reach them. Both use the repository-wide .dockerignore; only the guest rootfs build has one of its own, as build/Dockerfile.dockerignore — a <Dockerfile>.dockerignore replaces the repository-wide file rather than adding to it, which is worth knowing before writing a third.

Both images are stateless and hold no configuration. What they need:

	auth	api
DATABASE_URL	required	required
AUTH_ISSUER_URL	—	required, the issuer's public URL
AUTH_INTERNAL_URL	—	only if that URL is unroutable from here
EMAIL_SEND_URL EMAIL_API_KEY EMAIL_FROM	all three, or none	—
EMAIL_DEV_LOG	true prints codes instead of sending	—
STEAM_API_KEY	—	to link a Steam account
ADMIN_SHARED_SECRET	—	operator access
PORT	default 1337	default 3000

docker-compose.yml at the root wires all of it together with a Postgres, and is the smallest complete answer to "how do I run this myself".

Neither image terminates TLS or serves a certificate. Put a reverse proxy in front of them, point the hostnames at it, and keep the origin unreachable except through it.
