Vivarium Build Utils contains shared build utilities for Simulation Science projects.

Supported Python versions: 3.10, 3.11, 3.12, 3.13

You can install vivarium-build-utils from PyPI with pip:

pip install vivarium-build-utils

or build it from source by cloning the monorepo and installing this package:

git clone https://github.com/ihmeuw/vivarium-suite.git
cd vivarium-suite/libs/build-utils
conda create -n ENVIRONMENT_NAME
pip install -e .

Overview

This repository provides:

  • `vars/`: Jenkins shared library functions for continuous integration pipelines

  • `resources/`: Shared Makefiles and build scripts for consistent build processes

Note: for help with the Make targets available to any environment with this repository installed, run make help in the terminal.

Monorepo support

vivarium-build-utils supports both standalone repos and monorepos where many packages live under libs/<pkg>/. Standalone repos keep working with no changes; the sections below describe what’s needed for a monorepo.

Top-level Jenkinsfile (provisioner)

The monorepo’s root Jenkinsfile calls monorepo() to provision a Multibranch Pipeline for each per-package Jenkinsfile. Run this on the default branch only:

@Library('vivarium_build_utils') _

monorepo(
    jenkinsfiles: [
        'libs/core/Jenkinsfile',
        'libs/public-health/Jenkinsfile',
    ],
    // Jenkins credential ID for the GitHub App. Required, no default; vbu
    // stays org-agnostic so the literal UUID lives next to the org context.
    githubCredentialsId: 'fad62062-b1f4-447b-997f-005d6b1ea41e',
    folderPrefix: 'Public',  // optional, defaults to "Public"
)

The provisioned pipelines land under <folderPrefix>/<repo>/libs/<pkg>/.

Per-package Jenkinsfile

Each libs/<pkg>/Jenkinsfile calls reusable_pipeline() the same way a standalone repo would, with one new argument:

@Library('vivarium_build_utils') _

reusable_pipeline(
    test_types: ['unit', 'integration'],
    deployable: true,
    env_reqs: 'ci_jenkins',  // pyproject.toml extra to install
)

env_reqs selects which [project.optional-dependencies] extra make install pulls in. Omit it (or leave empty) on standalone repos to keep base.mk’s default of dev.

Deployable callers (deployable: true) can also pass github_credentials_id: '<jenkins-credential-id>' to override the git credential used at deploy time for pushing the release tag. When omitted, the deploy stage falls back to the credential configured on the Multibranch Pipeline’s branch source, which is the right default for most repos.

Tag prefix

The TAG_PREFIX environment variable controls both make tag-version and make validate-tag. It must be set consistently in both targets, or validate-tag will silently look at the wrong set of tags.

  • Standalone repos: leave unset. Tags are v<X.Y.Z>.

  • Monorepo libs: set TAG_PREFIX=vivarium-<lib>- (e.g. vivarium-core-). Tags become vivarium-<lib>-v<X.Y.Z>.

Release workflows that invoke make validate-tag or make tag-version should export TAG_PREFIX before running them.

Fetching from internal Artifactory

IHME_PYPI defaults to the internal Artifactory URL and is woven into EXTRA_INDEX_FLAGS for make install. Override it to empty (make install IHME_PYPI=) in environments that can’t reach IHME’s network (e.g. GitHub Actions runners). make deploy-package-artifactory requires a non-empty IHME_PYPI and is Jenkins/internal-only.

Cross-library PRs

A single PR can modify several interdependent monorepo libraries, including bumping one and consuming the new version of another even though the upstream’s dependency on it still resolves against PyPI (where the new version isn’t released yet). make install CHANGED_LIBS="<lib1> <lib2> ..." opts a build into in-tree resolution where any CHANGED_LIBS (libraries whose source changed in the PR) that are also (1) reachable from the package being built and (2) whose pending CHANGELOG.rst version satisfies the dependents’ pins are installed editably from local source (at the pending version) with a single uv invocation. Unchanged dependencies still resolve from PyPI.

CHANGED_LIBS is a no-op when empty, so single-package installs are unaffected.

The GitHub Actions CI and release workflows wire this automatically.
