Plugin Fees Helm Chart

This Helm chart installs Plugin Fees for Midaz, a high-performance and open-source ledger.

Install Plugin Fees Helm Chart

To install Plugin Fees using Helm, run the following command:

$ helm install plugin-fees oci://registry-1.docker.io/lerianstudio/plugin-fees-helm --version 1.0.0 -n midaz-plugins --create-namespace

This will create a new namespace called midaz-plugins if it doesn’t already exist and deploy the Plugin Fees Helm chart.

After installation, you can verify that the release was successful by listing the Helm releases in the midaz-plugins namespace:

$ helm list -n midaz-plugins

Upgrading

To upgrade the chart to a new version:

$ helm upgrade plugin-fees oci://registry-1.docker.io/lerianstudio/plugin-fees --version <new-version> -n midaz-plugins

Uninstalling

To uninstall the chart:

$ helm uninstall plugin-fees -n midaz-plugins

Configuring Ingress for Different Controllers

The Plugin Fees Helm Chart optionally supports different Ingress Controllers for exposing services when necessary. Below are the configurations for commonly used controllers.

Note: Before configuring Ingress, ensure that you have an Ingress Controller installed in your cluster. Examples include NGINX, AWS ALB, and Traefik.

NGINX Ingress Controller

To use the NGINX Ingress Controller, configure the values.yaml as follows:

ingress:
  enabled: true
  className: "nginx"
  annotations: {}
  hosts:
    - host: midaz.example.com
      paths:
        - path: /
          pathType: Prefix
  tls:
    - secretName: midaz-tls
      hosts:
        - midaz.example.com
