# Deploying Sure on Hostim.dev [Hostim.dev](https://hostim.dev) is a managed container-hosting platform that runs Sure with a managed PostgreSQL database, managed Redis, persistent storage, and automatic HTTPS — no server to provision or maintain. ## One-click template Sure is available as a one-click template. It provisions the Rails web server, the Sidekiq background worker, PostgreSQL, and Redis for you, and generates `SECRET_KEY_BASE` automatically. 1. Open the [Sure template](https://console.hostim.dev/dashboard?preview=1&modal=1&template=sure). 2. Choose a resource plan. 3. Click **Deploy**. 4. Open the generated domain and create your first account. A full walkthrough is in the [Hostim.dev Sure guide](https://hostim.dev/docs/templates/sure). ## Manual setup To configure the app yourself, create an app from the `ghcr.io/we-promise/sure:stable` image and set the following environment variables: | Variable | Value | | --- | --- | | `SECRET_KEY_BASE` | a long random hex string (keep it stable across restarts) | | `DB_HOST` / `DB_PORT` | your PostgreSQL host and port | | `POSTGRES_DB` / `POSTGRES_USER` / `POSTGRES_PASSWORD` | database credentials | | `REDIS_URL` | `redis://:/1` | | `SELF_HOSTED` | `true` | Run the web server and a Sidekiq worker from the same image, both sharing the same `SECRET_KEY_BASE`. Run `bin/rails db:prepare` before the web server starts so migrations are applied — for example with a start command like `sh -c "./bin/rails db:prepare && (bundle exec sidekiq &) && exec ./bin/rails server -b 0.0.0.0"`. Mount a persistent volume at `/rails/storage`. Sure stores uploaded files (such as imported statements) there via Active Storage's local disk service by default; without a persistent volume they are lost when the container is replaced, while the database still references them.
