Service lifecycle: POST /services/:id/clone duplicates config, volumes, domains, access gates, builder settings, and variables (secret ciphertext copied verbatim); POST /services/:id/move re-parents to another owned project. Both enforce ownership, reject name conflicts, and audit. Registries: CRUD at /registries — host-matched pull credentials for prebuilt-image deploys, encrypted at rest via secrets pkg, never returned (has_password flag). Empty password on update keeps the stored credential; host normalized (scheme/case/trailing slash). Credentials thread through BuildConfig → BuildRequest → pull auth config, used only for the pull. Surfaces: CLI services clone|move + registries group, 7 MCP tools, OpenAPI paths/schemas, frontend Lifecycle card (clone/move/delete) and Settings registries section, llms.txt + CLI.md.

Railpack Integration
This directory contains the build system for Containr, with Railpack as the primary build method.
Build Types
Railpack (Primary)
- Detection: Automatically detects supported frameworks (Node.js, Python, Go, Rust, Java, Ruby, PHP, Static)
- API: Uses https://api.railpack.app/v1/ for Dockerfile generation
- Fallback: Falls back to Nixpacks if Railpack cannot build the project
Nixpacks (Secondary)
- Detection: Used as fallback when Railpack detection fails
- Local: Runs locally without external API calls
Dockerfile
- Detection: Checks for existing Dockerfile in repository
- Priority: Highest priority if Dockerfile exists
Prebuilt
- Usage: For pre-built container images
- Configuration: Specified in service configuration
Supported Frameworks
Railpack supports the following frameworks:
- Node.js - package.json detection
- Python - requirements.txt detection
- Go - go.mod detection
- Rust - Cargo.toml detection
- Java - pom.xml or build.gradle detection
- Ruby - Gemfile detection
- PHP - composer.json detection
- Static - Static site detection
Usage
// Create build manager
buildManager := build.NewBuildManager("/tmp/builds", dockerClient)
// Build a project
response, err := buildManager.Build(ctx, &types.BuildRequest{
SourcePath: "/path/to/project",
ImageName: "my-app",
ImageTag: "latest",
})
API Endpoints

- Build Plan: POST https://api.railpack.app/v1/plan
Configuration
Railpack can be configured with:
- Custom build commands
- Custom start commands
- Environment variables
- Build root directory
