Deploying Anchore Enterprise on Amazon EKS

Get an understanding of the deployment of Anchore Enterprise on an Amazon EKS cluster and expose it on the public Internet.

Prerequisites

  • A running Amazon EKS cluster with worker nodes launched. See EKS Documentation for more information on this setup.
  • Helm client installed on local host.
  • AnchoreCTL installed on local host.

Once you have an EKS cluster up and running with worker nodes launched, you can verify it using the following command.

$ kubectl get nodes
NAME                             STATUS   ROLES    AGE   VERSION
ip-192-168-2-164.ec2.internal    Ready    <none>   10m   v1.14.6-eks-5047ed
ip-192-168-35-43.ec2.internal    Ready    <none>   10m   v1.14.6-eks-5047ed
ip-192-168-55-228.ec2.internal   Ready    <none>   10m   v1.14.6-eks-5047ed

Anchore Helm Chart

Anchore maintains a Helm chart to simplify the software deployment process. An Anchore Enterprise deployment of the chart will include the following:

  • Anchore Enterprise software
  • PostgreSQL (13 or higher)
  • Redis (4)

To make the necessary configurations to the Helm chart, create a custom anchore_values.yaml file and reference it during deployment. There are many options for configuration with Anchore. The following is intended to cover the minimum required changes to successfully deploy Anchore Enterprise on Amazon EKS.

Note: For this installation, an ALB ingress controller will be used. You can read more about Kubernetes Ingress with AWS ALB Ingress Controller here

Configurations

Make the following changes below to your anchore_values.yaml

Ingress

ingress:
  enabled: true
  apiPaths:
    - /v2/*
  uiPath: /*
  annotations:
    kubernetes.io/ingress.class: alb
    alb.ingress.kubernetes.io/scheme: internet-facing

Note: Configuring ingress is optional. It is used throughout this guide to expose the Anchore deployment on the public internet.

Anchore API Service

# Pod configuration for the anchore engine api service.
api:
  replicaCount: 1
  # kubernetes service configuration for anchore external API
  service:
    type: NodePort
    port: 8228
    annotations: {}

Note: Changed the service type to NodePort

Anchore Enterprise UI

ui:
  # kubernetes service configuration for anchore UI
  service:
    type: NodePort
    port: 80
    annotations: {}
    sessionAffinity: ClientIP

Note: Changed service type to NodePort.

AWS EKS Configurations

Create the IAM policy to give the Ingress controller the right permissions

  1. Go to the IAM Console.
  2. Choose the section Roles and search for the NodeInstanceRole of your EKS worker nodes.
  3. Create and attach a policy using the contents of the template iam-policy.json

Deploy RBAC Roles and RoleBindings needed by the AWS ALB Ingress controller from the template below:

wget https://raw.githubusercontent.com/kubernetes-sigs/aws-alb-ingress-controller/v1.0.0/docs/examples/rbac-role.yaml

kubectl apply -f https://raw.githubusercontent.com/kubernetes-sigs/aws-alb-ingress-controller/v1.0.0/docs/examples/rbac-role.yaml

Update ALB Ingress

Download the ALB Ingress manifest and update the cluster-name section with the name of your EKS cluster name.

wget https://raw.githubusercontent.com/kubernetes-sigs/aws-alb-ingress-controller/v1.0.1/docs/examples/alb-ingress-controller.yaml

# Name of your cluster. Used when naming resources created
# by the ALB Ingress Controller, providing distinction between
# clusters.
- --cluster-name=anchore-prod

Deploy the AWS ALB Ingress controller YAML:

kubectl apply -f alb-ingress-controller.yaml

Anchore Enterprise Deployment

Create Secrets

Enterprise services require an Anchore Enterprise license, as well as credentials with permission to access the private DockerHub repository containing the enterprise software.

Create a Kubernetes secret containing your license file:

kubectl create secret generic anchore-enterprise-license --from-file=license.yaml=<PATH/TO/LICENSE.YAML>

Create a Kubernetes secret containing DockerHub credentials with access to the private Anchore Enterprise software:

kubectl create secret docker-registry anchore-enterprise-pullcreds --docker-server=docker.io --docker-username=<DOCKERHUB_USER> --docker-password=<DOCKERHUB_PASSWORD> --docker-email=<EMAIL_ADDRESS>

Deploy Anchore Enterprise:

helm repo add anchore https://charts.anchore.io

helm install anchore anchore/enterprise -f anchore_values.yaml

It will take the system several minutes to bootstrap. You can checks on the status of the pods by running kubectl get pods:

$ kubectl get pods

Anchore System

Check the status of the system with AnchoreCTL to verify all of the Anchore services are up:

Note: Read more on Deploying AnchoreCTL

ANCHORECTL_URL=http://xxxxxx-default-anchoreen-xxxx-xxxxxxxxxx.us-east-1.elb.amazonaws.com ANCHORECTL_USERNAME=admin ANCHORECTL_PASSWORD=foobar anchorectl system status

Anchore Feeds

It can take some time to fetch all of the vulnerability feeds from the upstream data sources. Check on the status of feeds with AnchoreCTL:

ANCHORECTL_URL=http://xxxxxx-default-anchoreen-xxxx-xxxxxxxxxx.us-east-1.elb.amazonaws.com ANCHORECTL_USERNAME=admin ANCHORECTL_PASSWORD=foobar anchorectl feed list

Note: It is not uncommon for the above command to return a: [] as the initial feed sync occurs.

Once the vulnerability feed sync is complete, Anchore can begin to return vulnerability results on analyzed images. Please continue to the Usage section of our documentation for more information.
