# Deploying the control plane Two apps — [`apps/api`](../apps/api) and [`apps/auth`](../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`](dns.md). ## Locally Three ways, in increasing order of how much they resemble a deployment. ```sh cp .env.example .env # once; compose has no credentials of its own 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: ```sh bun run db:migrate # against DATABASE_URL ``` ## Cloudflare Workers Configuration is [`apps/auth/wrangler.jsonc`](../apps/auth/wrangler.jsonc) and [`apps/api/wrangler.jsonc`](../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 ```sh 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: ```sh 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 ``` The API has no secrets of its own to put here: every caller it accepts proves who it is — a session token from the issuer, a personal access token, or a registered host's own credentials — so there is nothing shared to leak. 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 ```sh 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 ```sh 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 `.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 | — | | `PORT` | default `1337` | default `3000` | [`docker-compose.yml`](../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, and neither marks the cookies it sets `Secure`, because both expect to sit behind something that does terminate TLS. So put a reverse proxy in front of them and keep the origin unreachable except through it — `docker-compose.yml` publishes their ports on loopback only for exactly this reason, and changing that to `0.0.0.0` is a way to reach the issuer *around* the proxy with codes and tokens in clear text.
