GFI: Automate Helm repository setup with a Taskfile command

Summary Create an automated Taskfile command that scans all Chart.yaml files and adds external Helm repositories in one command.

Type Enhancement

Context Currently, developers must manually run 7+ helm repo add commands for external dependencies (Bitnami, Prometheus, Grafana, OpenTelemetry, Istio, Codecentric, Vector) when cloning the repository. This creates friction for new contributors and is error-prone. The repository contains 8 Helm charts with various external dependencies that need to be added before charts can be used.

The current manual process requires developers to identify and add these repositories individually:

• helm repo add bitnami https://charts.bitnami.com/bitnami
• helm repo add prometheus-community https://prometheus-community.github.io/helm-charts
• helm repo add grafana https://grafana.github.io/helm-charts
• helm repo add opentelemetry https://open-telemetry.github.io/opentelemetry-helm-charts
• helm repo add istio https://istio-release.storage.googleapis.com/charts
• helm repo add codecentric https://codecentric.github.io/helm-charts
• helm repo add vector https://helm.vector.dev

Starter tasks

1. Examine existing charts/incubator/hyperswitch-app/Taskfile.yaml for the helm-add-repo pattern
2. Scan all Chart.yaml files in charts/incubator/ to identify external repository URLs
3. Add the new task to root Taskfile.yaml following existing patterns

Implementation hints

• File to modify: Taskfile.yaml (root level)
• Reference pattern: charts/incubator/hyperswitch-app/Taskfile.yaml has existing helm-add-repo task
• Required repositories:

  bitnami: https://charts.bitnami.com/bitnami
  prometheus-community: https://prometheus-community.github.io/helm-charts
  grafana: https://grafana.github.io/helm-charts
  opentelemetry: https://open-telemetry.github.io/opentelemetry-helm-charts
  istio: https://istio-release.storage.googleapis.com/charts
  codecentric: https://codecentric.github.io/helm-charts
  vector: https://helm.vector.dev
  

• Exclude: Filter out file:// repositories (local dependencies)
• Task structure:

  setup-helm-repos:
    desc: "Automatically add all external Helm repositories used by charts"
    cmds:
      - echo "Adding external Helm repositories..."
      # Add parsing and helm repo add logic here
      - helm repo update
      - echo "Helm repositories setup complete!"
    aliases:
      - shr
  

Acceptance criteria

• Task setup-helm-repos (alias shr) added to root Taskfile.yaml
• All 7 external repositories are added correctly
• Command task setup-helm-repos passes locally
• Command includes error handling for duplicate repositories (use || true)
• Command runs helm repo update after adding repositories
• Task provides clear output showing which repositories were added
• Test by removing existing repos and running the new task
