This repository contains the Helm charts and Kubernetes manifests used to deploy application components (such as the API service, MLflow, and related services).

Purpose

This repository stores Helm charts and configuration values to manage Kubernetes manifests, treating Git as the single source of truth.

The GitHub Actions workflow located in .github/workflows/update-helm.yml is responsible for updating the container image tag in values/api/values.yaml and pushing the changes back to the main branch.

Main Structure

• apps/ — umbrella chart and root application templates.
• values/ — subcharts and values.yaml files for each service:
  • values/api/values.yaml — file where the workflow automatically updates the container image tag.
  • values/mlflow/* — Helm chart and configuration for the MLflow service.

GitHub Actions: update-helm.yml

Workflow Summary

Triggers

• workflow_dispatch — manual trigger with input image_tag.
• repository_dispatch — triggered via API with client_payload.image_tag.

Workflow steps

1. Checkout the repository using secrets.PAT_TOKEN.
2. Retrieve the image tag from either the workflow input or the payload.
3. Replace the tag: value in values/api/values.yaml with the new image tag.
4. Commit and push the updated configuration back to the main branch using the PAT token.
