Deploying Anchore Enterprise on Azure Kubernetes Service (AKS)

This document will walk you through the deployment of Anchore Enterprise in an Azure Kubernetes Service (AKS) cluster and expose it on the public Internet.

Prerequisites

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

Once you have an AKS cluster up and running with worker nodes launched, you can verity via the following command.

$ kubectl get nodes

NAME                       STATUS   ROLES   AGE     VERSION
aks-nodepool1-28659018-0   Ready    agent   4m13s   v1.13.10
aks-nodepool1-28659018-1   Ready    agent   4m15s   v1.13.10
aks-nodepool1-28659018-2   Ready    agent   4m6s    v1.13.10

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, this document is intended to cover the minimum required changes to successfully deploy Anchore Enterprise in AKS.

Note: For this installation, an NGINX ingress controller will be used. You can read more about Kubernetes Ingress in AKS here.

Configurations

Make the following changes below to your anchore_values.yaml

Ingress

ingress:
  enabled: true
  labels: {}
  apiPaths:
    - /v2/
  uiPath: /
  annotations:
    kubernetes.io/ingress.class: nginx

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 api service.
api:
  # 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.

Install NGINX Ingress Controller

Using Helm, install an NGINX ingress controller in your AKS cluster.

helm install stable/nginx-ingress --set controller.nodeSelector."beta\.kubernetes\.io/os"=linux --set defaultBackend.nodeSelector."beta\.kubernetes\.io/os"=linux

Deploy Anchore Enterprise

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

mangy-serval-nginx-ingress-default-backend-8686cd585b-4m2bt       1/1     Running   0          21m

We can see that NGINX ingress controller has been installed as well from the previous step. You can view the services by running the following command:

$ kubectl get services | grep ingress

mangy-serval-nginx-ingress-controller                LoadBalancer   10.0.30.174    40.114.26.147   80:31176/TCP,443:30895/TCP                     22m
mangy-serval-nginx-ingress-default-backend           ClusterIP      10.0.243.221   <none>          80/TCP                                         22m

Note: The above output shows us that IP address of the NGINX ingress controller is 40.114.26.147. Going to this address in the browser will take us to the Anchore login page.

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://40.114.26.147/v2/ 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://40.114.26.147/v2/ 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.
