Install the Snyk Controller with Helm (Azure and Google Cloud Platform)

Ensure you have reviewed the prerequisites for installing the Snyk Controller.

To receive vulnerability details about your Kubernetes workloads, a Snyk admin must first install the Snyk Controller onto your cluster. The Snyk Controller is published in Helm Hub.

The installation steps cover:

• Snyk integration for most Kubernetes platforms

• Additional configuration steps for integration when using Amazon Elastic Container Registry (ECR) with your Amazon Elastic Kubernetes Service (EKS) clusters.

Mandatory installation steps for the Snyk Controller with Helm

To install the Snyk Controller with Helm:

1. Access your Kubernetes environment. Run the following command to add the Snyk Charts repository to Helm:

helm repo add snyk-charts https://snyk.github.io/kubernetes-monitor --force-update

2. After the repository is added, create a unique namespace for the Snyk Controller:

kubectl create namespace snyk-monitor

As a good practice for Kubernetes applications, use a unique namespace to isolate the controller resources easily.

Ensure you remember the namespace snyk-monitor. You will use it when configuring other resources.

Snyk monitor requires:

• Snyk Integration ID

• Service Account Token

• dockercfg.json file.

Install a public container registry

To install a public container registry, you must create a Kubernetes secret called snyk-monitorcontaining the Snyk Integration ID and the service account token.

To do this, run the following command:

kubectl create secret generic snyk-monitor -n snyk-monitor \
        --from-literal=dockercfg.json={} \
        --from-literal=integrationId=abcd1234-abcd-1234-abcd-1234abcd1234 \
        --from-literal=serviceAccountApiToken=bdca4123-dbca-4343-bbaa-1313cbad4231

For a successful integration, the secret must be called snyk-monitor.

Install the Snyk Helm chart

helm upgrade --install snyk-monitor snyk-charts/snyk-monitor \
             --namespace snyk-monitor \
             --set clusterName="Production cluster"

If you are running your own instance of Snyk, you must specify the API endpoint when installing the controller.

In the following command, provide the full hostname of your Snyk instance.

helm upgrade --install snyk-monitor snyk-charts/snyk-monitor \
             --namespace snyk-monitor \
             --set clusterName="Production cluster" \
             --set integrationApi=https://<server>/kubernetes-upstream

• Replace "Production cluster" with a name based on the cluster you are monitoring. You can use this label to find workloads in Snyk later.

• Using / (slash) in the cluster name is not allowed. Any /in the cluster names are removed.

• To avoid renaming the cluster on every update, you can use the existing option from Helm --reuse-values. When upgrading, Helm reuses the values from the last release and merges them in any overrides from the command line using --set and -f

Integrate AKS with ACR using Managed Identities

To do this:

1. When you use AKS with user-managed identities to authorize access to ACR, and there are multiple identities that assign the AcrPull role to the VM scale set, you must also specify the Client ID of the desired user-managed identity to be used. This value must be set as an override, in .Values.azureEnvVars:

azureEnvVars:
  - name: AZURE_CLIENT_ID
    value: "abcd1234-abcd-1234-abcd-1234abcd1234"

2. With the YAML above saved in override.yaml, run the following command:

helm upgrade --install snyk-monitor snyk-charts/snyk-monitor \
  --namespace snyk-monitor \
  -f override.yaml

By default, this value is set to an empty string, and it is not used as such.

When using the system-managed identity with the AcrPull role assigned, setting this variable is not necessary.

Update an existing installation

If you are an existing customer and are updating your Snyk Controller:

1. Create a service account token. For more information, see Prerequisites for installing the Snyk Controller. This token is stored in the snyk-monitor secret.

2. Delete your existing snyk-monitor secret:

kubectl delete secret snyk-monitor -n snyk-monitor

3. Follow the mandatory installation steps. To get the latest Helm chart version, run the following command:

helm repo add snyk-charts https://snyk.github.io/kubernetes-monitor --force-update
