Deploy and Host Docker Registry on Railway
Docker Registry is an open-source service from Docker that lets you host and manage your own container images privately. Instead of relying on Docker Hub or external registries, you can store, version, and distribute images directly from your own infrastructure.
About Hosting Docker Registry
Hosting a Docker Registry gives you full control over your image storage, access, and performance. It involves running a registry:2 container image, configuring filesystem or cloud-backed storage (like Railway volumes or S3), and exposing it securely via TCP or HTTPS. Using Railway, you can easily deploy the registry with persistent storage, define environment variables, and access it through a custom domain or TCP proxy for Docker CLI operations.
Common Use Cases
- Hosting private container images for internal projects
- Caching frequently used public images for faster CI/CD pipelines
- Serving images for multi-environment deployments or air-gapped setups
Dependencies for Docker Registry Hosting
- Docker (for building/pushing images)
