Deploying Anchore Enterprise on Google Kubernetes Engine (GKE)

Get an understanding of deploying Anchore Enterprise on a Google Kubernetes Engine (GKE) cluster and exposing it on the public Internet.

Note when using Google Cloud, consider utilizing Cloud SQL for PostgreSQL as a managed database service.

Prerequisites

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

Once you have a GKE cluster up and running with worker nodes launched, you can verify it by using the followiing command.

$ kubectl get nodes
NAME                                                STATUS   ROLES    AGE   VERSION
gke-standard-cluster-1-default-pool-c04de8f1-hpk4   Ready    <none>   78s   v1.13.7-gke.24
gke-standard-cluster-1-default-pool-c04de8f1-m03k   Ready    <none>   79s   v1.13.7-gke.24
gke-standard-cluster-1-default-pool-c04de8f1-mz3q   Ready    <none>   78s   v1.13.7-gke.24

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 Google Kubernetes Engine.

Note: For this deployment, a GKE ingress controller will be used. You can read more about Kubernetes Ingress with a GKE Ingress Controller here

Configurations

Make the following changes below to your anchore_values.yaml

Ingress

ingress:
  enabled: true
  apiPaths:
    - /v2/*
  uiPath: /*

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

Anchore 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.

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

The output above shows that an Load Balancer has been created. Navigate to the specified URL in a browser:

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://34.96.64.148 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 Anchore CTL:

ANCHORECTL_URL=http://34.96.64.148 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 Vulnerability Management section of our documentation for more information.
