Publish Langfuse to Artifact Hub 🚀

This GitHub Action is designed to publish the Langfuse Helm chart to Artifact Hub. It automates the process of packaging the Langfuse chart, updating the README.md, and pushing the changes to the repository. The action is triggered manually via the workflow_dispatch event.

Workflow Overview 🛠️

The workflow consists of the following steps:

1. Checkout the Repository: The repository is checked out to the local runner.
2. Check for Existing Langfuse Package: The action checks if the langfuse-${{ env.LANGFUSE_VERSION }}.tgz file already exists. If it does, the workflow is stopped to prevent overwriting the existing package.
3. Download Langfuse Tar File: The action downloads the specified version of the Langfuse chart from the GitHub releases.
4. Extract the Tar File: The downloaded .tgz file is extracted, and the directory structure is checked.
5. Replace the README File: The README.md file is replaced with the latest version from the repository.
6. Delete Tar File: The .tgz file is deleted after extracting.
7. Package the Chart: The Helm chart is packaged into a .tgz file.
8. Remove Langfuse Directory: The extracted Langfuse directory is removed after packaging.
9. Create Index File: The Helm chart repository index is updated to reflect the new package.
10. Push Changes to GitHub: The changes, including the packaged chart, updated README.md, and index.yaml, are committed and pushed to the repository.

How to Use 📝

1. Update the Version: Change the LANGFUSE_VERSION environment variable to the latest release version of the Langfuse repo.

   • Example: Update LANGFUSE_VERSION: "1.1.0" to the latest release version.

2. Update the README File:

   • Copy the latest version of the README from the Langfuse GitHub Repository.
   • Paste it into the ./readme/README.md file in the repository.
   • Important: Change the source URL in the README from https://langfuse.github.io/langfuse-k8s to https://skyu-io.github.io/langfuse-helm-chart.

3. Run the GitHub Action: Trigger the action by running the workflow manually using the workflow_dispatch event in the GitHub Actions UI.

Notes ⚠️

• If the package for the specified version already exists, the action will fail to prevent overwriting the existing chart.
