Exivity Helm Chart

This Helm chart deploys Exivity, a comprehensive cloud metering and billing solution, on Kubernetes clusters.

Prerequisites

• Kubernetes 1.20+
• Helm 3.0+
• A StorageClass that supports ReadWriteMany access mode (for shared storage)

Getting Started

1. Add the Helm Repository

helm repo add exivity https://charts.exivity.com
helm repo update

2. Install the Chart

Install Exivity with your desired release name:

helm upgrade --install exivity exivity/exivity \
    --namespace exivity \
    --create-namespace \
    --wait \
    --set storage.storageClass=<your-storage-class>

Replace <your-storage-class> with your preferred storage class that supports ReadWriteMany access mode.

3. Storage Solutions

Exivity is tested with various storage solutions including NFS and Longhorn. Here are examples for common setups:

NFS Storage with nfs-ganesha-server-and-external-provisioner

# Install NFS server provisioner
helm repo add nfs-ganesha-server-and-external-provisioner https://kubernetes-sigs.github.io/nfs-ganesha-server-and-external-provisioner/
helm install nfs-server nfs-ganesha-server-and-external-provisioner/nfs-server-provisioner \
    --namespace nfs-server \
    --create-namespace \
    --wait \
    --set persistence.enabled=true \
    --set persistence.size=5Gi \
    --set storageClass.name=nfs-client

# Then install Exivity
helm upgrade --install exivity exivity/exivity \
    --namespace exivity \
    --create-namespace \
    --wait \
    --set storage.storageClass=nfs-client

Longhorn Storage (Beta Support)

If you're using Longhorn, you can install Exivity with:

Note: Longhorn support is currently in beta. While it works, we cannot ensure the same level of stability as NFS storage solutions.

helm upgrade --install exivity exivity/exivity \
    --namespace exivity \
    --create-namespace \
    --wait \
    --set storage.storageClass=longhorn

Configuration

Basic Configuration

Parameter	Description	Default
licence	Exivity license key (use "demo" for evaluation)	"demo"
storage.storageClass	Storage class for persistent volumes	""
ingress.enabled	Enable ingress	true
ingress.host	Hostname for the ingress	"exivity"

Example: Custom Values

Create a values.yaml file:

licence: "your-license-key"
storage:
  storageClass: "nfs-client"
ingress:
  enabled: true
  host: "exivity.example.com"
  tls:
    enabled: true
    secret: "exivity-tls"

Install with custom values:

helm upgrade --install exivity exivity/exivity \
    --namespace exivity \
    --create-namespace \
    --values values.yaml

Advanced Configuration

For detailed configuration options, see the examples directory:

• GUI as Website - Configure ingress for web access
• External PostgreSQL - Use external PostgreSQL
• External RabbitMQ - Use external RabbitMQ
• Larger PostgreSQL - Scale PostgreSQL resources

Accessing Exivity

After installation, Exivity will be available at:

• With Ingress: http(s)://<your-hostname>/
