Stratos on EKS

EKS Setup

Follow the instructions outlined in https://docs.aws.amazon.com/eks/latest/userguide/getting-started.html to deploy an EKS cluster.

If you plan to deploy SCF in the cluster, make the following modifications when creating the worker nodes.

• Set NodeInstanceType to t2.large
• Set NodeInstanceVolume to 75

Helm Setup

Download the latest Helm release (at least 2.9 is required for RBAC support) from https://github.com/helm/helm/releases

Save the following to a file caleld helm-rbac.yaml

apiVersion: v1
kind: ServiceAccount
metadata:
  name: tiller
  namespace: kube-system
---
apiVersion: rbac.authorization.k8s.io/v1beta1
kind: ClusterRoleBinding
metadata:
  name: tiller
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin
subjects:
  - kind: ServiceAccount
    name: tiller
    namespace: kube-system

Apply the configuration to the EKS cluster

$ kubectl apply -f helm-rbac.yaml

Install Helm

$ helm init --service-account tiller

Storage Classes

Stratos requires a storage class that is scoped to a single AZ.

To setup the scoped storage class, save the following to scoped_storage_class.yaml.

kind: StorageClass
apiVersion: storage.k8s.io/v1
metadata:
  name: gp2scoped
provisioner: kubernetes.io/aws-ebs
parameters:
  type: gp2
  zone: "us-east-1a"
reclaimPolicy: Retain
mountOptions:
  - debug

To create the storage class, execute the following:

$ kubectl apply -f scoped_storage_class.yaml

In this guide, the scoped storage class will be referred to as gp2scoped.

Stratos Deployment

To deploy Stratos on EKS, the following configuration overrides are required, save the following to a file named stratos-values.yaml.

storageClass: gp2scoped
useLb: true

Install stratos with Helm

$ helm install stratos/console -f stratos-values.yaml --namespace stratos --name stratos
