Metadata

Project-specific behavior lives under .dagger in the caller's Rush repository. This module treats those files as the public extension contract.

Exact field validation is defined by JSON schemas under ../schemas.

For editor integration in external projects, prefer exact versioned schema URLs. For example:

# yaml-language-server: $schema=https://bootstraplaboratory.github.io/rush-delivery/schemas/v0.6.1/deploy-target.schema.json

The root https://bootstraplaboratory.github.io/rush-delivery/schemas/ URLs track the current release. Exact paths such as /schemas/v0.6.1/... are the stable contract for projects pinned to that Rush Delivery version.

Package Release

Package release metadata lives in .dagger/release/npm.yaml. It is separate from deploy target metadata because npm package releases are registry side effects, not deploy mesh targets.

Repositories that only use release-packages do not need deploy metadata such as .dagger/deploy/services-mesh.yaml. Rush cache metadata is only required when a Rush cache provider such as github is enabled.

The first supported release strategy uses Rush change files. Rush remains the source of truth for package selection, version changes, changelogs, and publishable package rules.

# yaml-language-server: $schema=https://bootstraplaboratory.github.io/rush-delivery/schemas/v0.6.1/npm-release.schema.json

kind: npm

versioning:
  strategy: rush-change-files
  target_branch: main

auth:
  kind: token
  token_env: NPM_TOKEN

publish:
  registry: https://registry.npmjs.org/
  tag: latest
  access: public
  provenance: true

For token auth, keep the npm token in the release env file and reference it from common/config/rush/.npmrc-publish, for example:

//registry.npmjs.org/:_authToken=${NPM_TOKEN}

Pull-request validation runs Rush change-file verification when npm release metadata is present. Live releasePackages runs the standard Rush lifecycle, lets Rush apply the change files, publishes packages, and pushes the generated version commit back to versioning.target_branch.

Schema: ../schemas/npm-release.schema.json

Deploy Services Mesh

.dagger/deploy/services-mesh.yaml defines deploy target ordering:

• services.<target>.deploy_after lists targets that must finish first.
• Targets with no dependency can run in the same deploy wave.
• Service names must match deploy target metadata names.

Schema: ../schemas/deploy-services-mesh.schema.json

Deploy Targets

Deploy targets live in .dagger/deploy/targets.

Each target declares:

• name: target name. It should match the metadata filename and Rush package.
• deploy_script: repository-relative script executed by the target runtime.
• runtime.image: base image for the executor container.
• runtime.install: toolchain preparation commands.
• runtime.pass_env: allowed 1:1 host-to-container environment variables.
• runtime.map_env: allowed renamed environment variables, written as TARGET_ENV: SOURCE_ENV.
• runtime.env: static container environment values.
• runtime.dry_run_defaults: safe defaults used during dry-runs.
• runtime.required_host_env: host environment keys required for live runs.
• runtime.file_mounts: files mounted into the runtime container from the deploy runtime files bundle, or from host env paths for compatibility.
• runtime.workspace: directories and files mounted under /workspace.

If runtime.workspace.mode is full, the whole prepared repository is mounted. If mode is omitted, only listed dirs and files are mounted.

Runtime file mounts use a source path relative to the runtimeFiles bundle. target is optional and defaults to /runtime-files/<source>.

runtime:
  env:
    GOOGLE_APPLICATION_CREDENTIALS: /runtime-files/gcp-credentials.json
  file_mounts:
    - source: gcp-credentials.json

The source path must stay inside the runtime files bundle: no absolute paths and no .. segments. Live deploys that reference source mounts require the runtimeFiles Dagger input. Dry-runs report the intended mount and do not require the file.

Compatibility mounts can still read a host path from an allowlisted environment variable and mount it at an explicit target:

runtime:
  required_host_env:
    - GOOGLE_GHA_CREDS_PATH
  file_mounts:
    - source_var: GOOGLE_GHA_CREDS_PATH
      target: /tmp/gcp-credentials.json

For renamed deploy env with runtime.map_env, runtime.dry_run_defaults are keyed by the source variable name.

runtime.pass_env, runtime.map_env, and static runtime.env share one output environment namespace and have no precedence order. If they resolve the same output name with different values, Rush Delivery fails instead of silently overriding one value with another.

Schema: ../schemas/deploy-target.schema.json

Package Targets

Package targets live in .dagger/package/targets.

Package targets can also declare build-time environment for the generic Rush verify, lint, test, and build stage:

• build.pass_env: allowed 1:1 variables from the deploy env file.
• build.map_env: allowed renamed variables, written as TARGET_ENV: SOURCE_ENV.
• build.dry_run_defaults: safe values used when workflow dry-run mode is enabled and a source variable is not present.

build:
  pass_env:
    - WEBAPP_URL
  map_env:
    VITE_GRAPHQL_HTTP: WEBAPP_VITE_GRAPHQL_HTTP
  dry_run_defaults:
    WEBAPP_URL: https://webapp.example.test
    WEBAPP_VITE_GRAPHQL_HTTP: https://api.example.test/graphql

Rush Delivery merges build env from all selected package targets into the shared Rush build container. If two selected targets resolve the same target environment variable to different values, the build fails with a metadata error. For map_env, dry_run_defaults are keyed by the source variable name.

build.pass_env and build.map_env also have no precedence order. Both add explicit build environment variables. If they resolve the same output name with different values, Rush Delivery fails instead of silently overriding one value with another.

Supported artifact types:

• directory: an already-built repository directory.
• rush_deploy_archive: a Rush deploy output packaged for a deploy target.

Schema: ../schemas/package-target.schema.json

Validation Targets

Validation targets live in .dagger/validate/targets.

They declare optional backing services and ordered validation steps. This keeps target-specific smoke checks in metadata while the runner stays generic.

Schema: ../schemas/validation-target.schema.json

Toolchain Images

Toolchain image provider metadata lives in .dagger/toolchain-images/providers.yaml.

It declares optional registry providers for reusable framework toolchain images. Provider off needs no metadata. Provider github uses GHCR with environment keys for repository, username, and token.

Schema: ../schemas/toolchain-image-providers.schema.json

Rush Cache

Rush cache metadata lives in .dagger/rush-cache/providers.yaml.

The cache section defines:

• version: user-controlled cache snapshot tag. Bump it when you intentionally want to start a fresh Rush install cache namespace.
• paths: repository-relative Rush install cache paths restored into the Dagger-owned source.

The providers section declares optional storage adapters.

Schema: ../schemas/rush-cache-providers.schema.json
