RPM (Repo Manager)

Language-agnostic build orchestration and local environment runtime for monorepos.

Command Model

RPM has a clear split between build/test/run orchestration and environment runtime orchestration:

• rpm build builds filesystem-output targets only.
• rpm env create, rpm env render and rpm env up handle local environment workflows.
• Target suffixes are ordinary target name text; environment membership comes from explicit blueprint target refs.
• Environment containers are runtime dependencies declared once in repo.yml and referenced by name from bundles.

Installation

wget -qO- https://raw.githubusercontent.com/vcnkl/rpm/main/install.sh | sh

Configuration

Global (repo.yml)

project:
  name: 'my-project'          # Required; used for generated runtime resource names
shell: '/usr/bin/env bash'    # Default shell for commands
env:
  vars:                       # Global environment variables
    PROJECT: 'my-project'
  deps:                       # Docker runtime dependencies available to bundles
    - name: postgres
      image: postgres:16
      env:
        POSTGRES_PASSWORD: example
      ports:
        - "5432"                  # Publishes an ephemeral host port; injects POSTGRES_PORT
      volumes:                # Container data paths only; Docker volume names are generated
        - /var/lib/postgresql/data
      readiness-cmd: |
        timeout 90s bash -c "until docker exec ${DOCKER_CONTAINER_NAME} pg_isready; do sleep 5; done"
    - name: redis
      image: redis:7
logger:
  datetime:
    format: '2006-01-02T15:04:05Z07:00' # Go time layout for rpm log timestamps
init:                         # External dependencies to check/install
  - label: node
    check_cmd: 'node --version'
    install_cmd: 'nvm install 20'
ignore:
  - 'path/to/ignored/bundle/*'

Bundles (rpm.yml)

name: my-service              # Bundle name (used in target IDs)
env:                          # Environment-related bundle configuration
  variables:                  # Bundle-level environment variables
    SERVICE_PORT: '8080'
targets:
  - name: build               # Target name → ID becomes "my-service:build"
    deps:                     # Dependencies (other targets)
      - common:codegen
    in:                       # Input files/globs for cache key
      - '**/*.go'
      - 'go.mod'
    out:                      # Output files to check for cache validity
      - '.build/my-service'
    env:                      # Target-level environment variables
      CGO_ENABLED: '1'
    cmd: 'go build -o .build/my-service .'
    config:
      working_dir: 'local'    # 'local' (bundle dir), 'repo_root', or relative path
      index: 1                # Optional before-target ordering hint for rpm env up
      dotenv:
        enabled: true         # Load .env from bundle directory
      reload: true            # Environment runtime reloads on file changes
      ignore:                 # Environment runtime ignore patterns
        - 'tmp'
        - '*.log'

Bundle environment dependency requirements are declared under env.deps as names that must exist in top-level repo.yml env.deps. They are only used by rpm env up; they are not build outputs and do not participate in build cache validation.

name: api
env:
  deps:
    - postgres
    - redis
targets:
  - name: echo-123
    cmd: go run .

Usage

Build

rpm build [targets...]              # Build specific targets
rpm build                           # Build all *_build targets
rpm build --force core              # Force rebuild (ignore cache)
rpm build --dry-run core            # Show what would be built
rpm build -j 4 core                 # Limit parallel jobs

Test

rpm test [targets...]               # Run specific test targets
rpm test                            # Run all *_test targets

Run target

rpm run <target>                    # Run any target by exact ID
rpm run core:migrate                # Example: run migration target

Init

rpm init                            # Initialize .rpm directory, run `init` scripts and validate config

Show dependency graph

rpm graph [target]                  # Show dependency graph

Env

rpm env create [blueprint] --target bundle:target
rpm env create [blueprint] --target bundle:target --before bundle:target
rpm env edit <blueprint> --add-target bundle:target --add-before bundle:target
rpm env validate <blueprint>
rpm env render <blueprint> [--out path]
rpm env up <blueprint> [--non-interactive] [--no-reload] [--no-deps]
rpm env down <blueprint>  # or enter `q` to quit interactive session
rpm env prune <blueprint>

Blueprint files:

• .rpm/envs/<name>/config.yml.
• .rpm/envs/<name>/runtime.gen.star.

version: 1
name: local-stack
live_reload:
  enabled: true
  debounce: 100ms
before:
  - go-app:migrate
targets:
  - ref: go-app:echo-123
    reload: true
    env:
      APP_PORT: "8080"
  - ref: ts-app:web
    reload: true
dependencies:
  enabled: true
  include:
    - postgres
    - redis
  exclude: []
variables:
  LOG_LEVEL: debug

Global Flags

• --debug, -d: Enable debug logging
• --config, -c: Path to repo.yml (default: auto-detect via git root)
• --jobs, -j: Max parallel jobs (default: NumCPU)

Environment Variables

Composed in order (later overrides earlier):

1. System environment
2. repo.yml env
3. REPO_ROOT (auto-set)
4. BUNDLE_ROOT (auto-set)
5. Bundle env
6. Target env
7. Blueprint variables
8. Blueprint target env
9. .env file (if config.dotenv.enabled)

Caching

• Input hash: SHA256 of all files matching in patterns
• Generated state is stored under ignored .rpm/cache/, including build cache, DAG cache and generated Starlark.
• Cache hit requires: same input hash + all out files exist
• Dependency rebuild propagates to dependents

Environment Runtime

• Target commands use the resolved working directory from config.working_dir.
• Target environments compose values in this order: host env, repo env, REPO_ROOT, BUNDLE_ROOT, bundle env, target env, blueprint variables, blueprint target env and configured dotenv files.
• Stack before target refs use the same target command, working directory, environment and dotenv behavior as normal targets.
• Watch roots default to the bundle root or the target in patterns, and ignore entries come from target config.
• --no-reload disables watchers at runtime without mutating the committed blueprint.
• --no-deps skips dependency containers while still running targets.
• Runtime dependencies use Docker CLI orchestration: network creation, volume creation, detached containers, container removal and network removal.
• Runtime planning is intentionally modular: blueprint loading, normalized environment spec, Starlark generation, Starlark evaluation, runtime interfaces and the centralized environments/tui bridge are separate packages so future commands can compose them without changing blueprint semantics.
