README

Helps generating artifacts for Drupal by wrapping all code into an artifact, and pushing it to the artifact remote repository.

Installation

composer require metadrop/drupal-artifact-builder

Configuration

Drupal artifact builder allow using a configuration file to create the artifact. Artifacts usually are executed using always the same parameters. So, a configuration file saves time adding those parameters every time the command is run.

Configuration file is placed at root (it can be changed through command line parameters). You cam copy the template to have an starting point:

cp vendor/metadrop/drupal-artifact-builder/.drupal-artifact-builder.yml.dist .drupal-artifact-builder.yml

Configuration properties

commands: Commands to run inside the artifact folder before packaging.

Example:

commands:
    - composer install --no-dev
    - cd web/themes/custom/foo/ && npm install && npm run production

repository: Repository URL (git SSH / git HTTP URL).

Example:
```
repository: git@github.com:example/example-artifact.git
```
include: Extra files or folders to include into the artifact.

Example:
```
include:
  - oauth
  - solr
```
author: It will be the author used in git commits.

Example:
```
author: John Doe <passionate.developer@example.com>
```
branches_map: Key value map to git push source artifact branches to different artifact branches.

Example:
```
branches_map:
  develop:develop-build
```

This example will make push the artifacts coming from develop source branch to the develop-build artifact branch.

Usage

Important: Please note that Drupal Artifact Builder does not download Composer libraries or compile CSS assets. These tasks must be completed prior to running the command.

Builds the artifact and push the changes to git:

drupal-artifact-builder

Generate the artifact:

drupal-artifact-builder create

Push the created artifact to git:

drupal-artifact-builder git

Parameters

branch: Branch to create the artifact from / to. Required.
config: Allow setting the configuration file. Defaults to .drupal-artifact-builder.yml
```
drupal-artifact-builder git  folder/.drupal-artifact-builder.custom.yml
```

repository: Selects the repository where the artifacts will be pushed.

Examples:

For the complete command (create + git):

drupal-artifact-builder --repository git@example.com:example/example.git

For the git command:

drupal-artifact-builder git --repository git@example.com:example/example.git

include: Allow adding more paths to the artifact.

drupal-artifact-builder --repository git@example.com:example/example.git --include=oauth.json,mycustomapp

Artifact folder location

By default the artifact is built inside the system temporary directory (the value of sys_get_temp_dir(), typically /tmp on Linux). This means you do not need to add the artifact folder to .gitignore.

To use a different location, pass the --artifact-folder option:

drupal-artifact-builder --artifact-folder /custom/path/artifact
drupal-artifact-builder --artifact-folder relative/path/artifact

Relative paths are resolved from the Drupal project root. Absolute paths are used as-is.

In sandboxed CI environments where /tmp is not writable, override the base temp directory via the standard TMPDIR environment variable:

TMPDIR=/workspace/tmp drupal-artifact-builder

Running without a source git repository

drupal-artifact-builder create normally relies on the source project being a git working tree. When run in an environment where the codebase is present on disk without a .git directory (for example, when it has been extracted from a tarball or a snapshot in a CI image), the command bootstraps a throwaway git repository in the source root so that the same git archive based pipeline can be used, and removes it after the artifact is generated.

Caveats in this mode:

--branch is mandatory; auto-detection from the current branch is not possible.
hash.txt cannot reference a real commit; it is filled with a synthetic-YYYYMMDD-HHMMSS placeholder.

CI integration

GitHub Actions

A ready-to-use workflow is available at examples_ci/github-actions.yml. Copy it into your Drupal project at .github/workflows/deploy-artifact.yml and follow these steps:

Generate an SSH key pair for the artifact repository:

ssh-keygen -t ed25519 -C "artifact-deploy" -f artifact_deploy_key -N ""

Add the public key (artifact_deploy_key.pub) as a deploy key with write access in the artifact repository settings (Settings > Deploy keys).
Add the private key (artifact_deploy_key) as a repository secret named ARTIFACT_DEPLOY_KEY in the source Drupal repository (Settings > Secrets and variables > Actions).
Adjust the workflow to your needs:
- Update the branches list under on.push to match the branches you want to deploy.
- Change the Docker image tag (php8.3-node20) to match your PHP and Node versions. Available tags are listed in the drupal-artifact-builder-docker repository.
Make sure .drupal-artifact-builder.yml exists in your project root and has the repository key pointing to the artifact repository.

The workflow runs inside the ghcr.io/metadrop/drupal-artifact-builder-docker image, which provides PHP, Composer, Node, and Git out of the box.

Upgrade from 1.x to 2.x

2.0.0 release brings breaking changes and the way to use drupal-artifact-builder changes.

These steps must be followed in order to upgrade to the 2.0.0 version:

Copy and configure .drupal-artifact-builder.yml:

cp vendor/metadrop/drupal-artifact-builder/.drupal-artifact-builder.yml.dist .drupal-artifact-builder.yml

Change --extra-paths parameters to --include

Before:

drupal-artifact-builder --extra-paths solr

Now:

drupal-artifact-builder --include solr

Stop using GIT_BRANCH environment variable, now it is --branch

Before:

GIT_BRANCH=develop drupal-artifact-builder

Now:

drupal-artifact-builder --branch develop

Upgrade from 2.x to 3.x

To be able to bring composer libraries and compile the custom theme, configure commands in .drupal-artifact-builder.yml.

Example:
```yaml
commands:
    - composer install --no-dev
    - cd web/themes/custom/foo/ && npm install && npm run production
```

metadrop / drupal-artifact-builder
