Eno

What is Eno?

Eno is a new take on configuration management for Kubernetes.

• Generate configurations using short-lived pods, language-agnostic
• Dynamically regenerate when input resources change (without writing a controller!)
• Manage risk when updating many similar configurations
• Define complex ordering relationships
• Control any number of low-trust clusters from a single management cluster
• Support high object cardinality (10s of thousands)

Getting Started

export TAG=$(curl https://api.github.com/repos/Azure/eno/releases | jq -r '.[0].name')
kubectl apply -f "https://github.com/Azure/eno/releases/download/${TAG}/manifest.yaml"

Next, create a minimum viable Eno configuration to make sure everything works. This manifest will create a configmap called "some-config" in the default namespace.

kubectl apply -f "https://raw.githubusercontent.com/Azure/eno/refs/heads/main/examples/minimal/example.yaml"

# The configmap should be created by Eno soon after
kubectl get cm some-config -o=yaml
