Package and push files to a remote repository

What is it?

A tool to assemble a code artifact from your codebase, remove unnecessary files, and push it into a separate Git repository.

Why?

In hosting environments like Acquia, there are restrictions on the languages or frameworks available for building applications—for instance, the inability to run composer install due to a read-only filesystem. Consequently, a website source code has to be developed in a separate (source) repository, then assembled into a code artifact either locally or via CI, and then transferred to the hosting provider's version control system (destination repository).

This tool facilitates such processes seamlessly: it uses a .gitignore.deployment file to determine which files should be transferred to the destination repository, ensuring only necessary files are included and leaving out those specified by the ignore file.

Furthermore, since the destination repository requires a commit to incorporate changes from the artifact (like CSS, JS, etc.), the tool offers two options for this commit: force-push or branch, accommodating different workflow preferences.

See example of deployed artifact in Artifact branches.

Modes

force-push mode (default)

Push the packaged artifact to the same branch in the destination repository, carrying over the history from the source repository while overwriting the existing history in the destination repository.

Use case

Forwarding all changes from the source repository to the destination repository as-is for every branch: for example, a commit in the source repository branch feature/123 would create a commit in the destination repository branch feature/123. The next commit to the source repository branch feature/123 would update the destination repository branch feature/123 with the changes, but would overwrite the last "deployment" commit.

branch mode

Push packaged artifact to the new branch on each deployment, preserving history from the source repository, but requiring to trigger a deployment of newly created branch after each deployment.

Use case

Creating a new branch in the destination repository for every tag created in the source repository: for example, a tag 1.2.3 in the source repository would create a branch deployment/1.2.3 in the destination repository. The addition of the new tags would create new unique branches in the destination repository.

Installation

composer require --dev drevops/git-artifact

or download the latest release from the GitHub releases page.

Usage

./git-artifact git@github.com:yourorg/your-repo-destination.git

This will create an artifact from current directory and will send it to the specified remote repository into the same branch as a current one.

Run in CI

See examples:

• GitHub Actions
• CircleCI

Call from CI configuration or deployment script:

export DEPLOY_BRANCH=<YOUR_CI_PROVIDER_BRANCH_VARIABLE>
./git-artifact git@github.com:yourorg/your-repo-destination.git \
  --branch="${DEPLOY_BRANCH}" \
  --push

See extended and fully-configured example in the Scaffold project.

Options

Modifying artifact content

--gitignore option allows to specify the path to the artifact's .gitignore file that replaces existing .gitignore (if any) during the build. Any files no longer ignored by the replaced artifact's .gitignore are added into the deployment commit. If there are no no-longer-excluded files, the deployment commit is still created, to make sure that the deployment timestamp is captured.

Token support

Tokens are pre-defined strings surrounded by [ and ] and may contain optional formatter (for flexibility). For example, [timestamp:Y-m-d] is replaced with the current timestamp in format Y-m-d (token formatter), which is PHP date() expected format.

Both --branch and --message option values support token replacement.

Available tokens:

• [timestamp:FORMAT] - current time with a PHP date()-compatible FORMAT.
• [branch] - current branch in the source repository.
• [tags:DELIMITER] - tags from the latest commit in the source repository separated by a DELIMITER.
