Gemfile, install dependencies and build an image. - 03It goes liveYour app gets a container, free SSL and a live https://….dockhosting.cloud URL.

Shared Ruby hosting tends to freeze the Ruby version and bundler path at signup. DockHosting reads your Gemfile.lock, installs with Bundler and runs your app under a production-tuned Puma.
| Feature | DockHosting | Ruby shared hosting |
|---|---|---|
| First deploy | bundle install, run migrations, zero-downtime switch | Upload code to a frozen Ruby/bundler setup |
| Runtime & dependencies | Auto-detected and matched to your lockfile | Whatever version the host pinned at signup |
| HTTPS | Automatic Let's Encrypt on your subdomain and custom domains | Manual certificate setup and renewal (or a paid add-on) |
| Process supervision | Automatic restarts and zero-downtime releases | You babysit it, or hope the panel restarts it |
| Managed database | 1 included on Free, unlimited on Pro/Team | Host it yourself, or pay for a separate add-on |
| Idle / always-on | Sleep + instant wake (Free) or always-on (Pro/Team) | You pay for an idle server 24/7 |
| Pricing | Flat $0 / $4 / $9 / $19 per month, no metering | Server cost + setup fees + your time |
The bottom lineRails and Sinatra both get a reproducible gem set, automatic migrations and a managed database on the Free plan - shared Ruby hosts rarely offer any of it.
Everything you need to know before you deploy your first Ruby app.
Yes - db:migrate runs automatically on deploy, before traffic is switched to the new release.
