How it works
- 01Run dock deployRun
dock deployin your project folder, or connect a GitHub repository. - 02We build itWe detect Ruby on Rails from
config/application.rb, install dependencies and build an image. - 03It goes liveYour app gets a container, free SSL and a live https://….dockhosting.cloud URL.
$ dock deploy→ Detecting framework… Ruby on Rails→ Found config/application.rb→ bundle install && rails assets:precompile→ Building image→ Provisioning container + SSL✓ Live at https://my-app.dockhosting.cloud

Compare
Real Rails hosting moved to managed platforms for a reason: gems, migrations, assets and background jobs are a lot of moving parts. DockHosting runs Rails under a tuned Puma, precompiles assets on deploy and runs db:migrate before the traffic switch.
| Feature | DockHosting | shared Ruby on Rails hosting |
|---|---|---|
| First deploy | bundle install → precompile assets → migrate → switch | Upload to a shell account with a fixed gem environment |
| 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 lineReproducible Gemfile.lock installs, automatic migrations and a managed database put Rails deploys on the same good footing as any other stack here.
Everything you need to know before you deploy your first Ruby on Rails app.
Yes - db:migrate runs automatically on deploy, before traffic is switched to the new release.
