+enabling build

+- `docker-compose.yml` must expose your database, in my example it's `mongo` exposed on `27018`
+- `docker-compose.yml` must include `network: host` in the payload `build:` section so it can access the db
+- `Dockerfile` overrides the `.env` database with the host-relative connection string: `ENV DATABASE_URI="mongodb://127.0.0.1:27018/payload"`
+
+still problematic
+
+- `nextcache` is not right, i get errors about `permission denied, mkdir '/app/.next/cache/fetch-cache`. 
+  - next bulid happens as root but runtime we're not root. should probably just chown it in build and not volume mount
+  - if mounting, should be `.next/cache` and writable by 1001:1001
