Free Docker hosting
Free Docker hosting on HostKB — bring a Dockerfile, connect Git, and deploy any containerized app.
Free Docker hosting
Free Docker hosting and deploy from Git on HostKB — builds, HTTPS, and logs included.
- Free application hosting so you can deploy Docker without renting a VPS first
- Deploy from a Git repo that includes a Dockerfile, or use a public pre-built image
- One platform for Node, Python, .NET, Java, PHP, and more — as long as it is containerized
- Git-based deployments with builds, HTTPS, custom domains, and real-time logs
- Optional auto-deploy on push for continuous deployment
How to deploy Docker on HostKB
Free deployment from Git: connect repo → build → deploy → HTTPS URL.
- Create a free HostKB account and open a project.
- Create an application with source type Git Repository (deploy from GitHub guide).
- Add a Dockerfile (or use Railpack when available) so the platform can build your Docker app.
- Set environment variables, then click Build and Deploy.
- Open your app URL and attach a custom domain when you go live.
Docker Dockerfile tip
Keep the Dockerfile at the repo root (or set the Dockerfile path / root directory in app settings). EXPOSE the HTTP port your process listens on.
Why use HostKB for Docker
- One place to host and deploy — free to start, grow when you need
- Works for APIs, web apps, and containerized services — not only static sites
- Scale later with app sizes without changing your Git workflow
