Add Helm support for AWS Account posture scanner

[lumattr]

Additional context
It would be great if the AWS account scanner would be deployed in helm. I Appreaciate that it takes additional effort due to the need to have a Service account and an IAM role attached, but as i have the console and agents already in K8s its awkward to have a seperate ECS cluster for the account scanner.

Is your feature request related to a problem? Please describe.
A clear and concise description of what the problem is. Ex. I'm always frustrated when [...]

Describe the solution you'd like
Ideally it would be a helm chart that would run the cloud-scanner image, and would require me as the end user to create a role with the needed policy, attach that to a service account and pass that to the helm chart.

Describe alternatives you've considered
This could be a terraform module, but that wouldnt work for me specifically as we use CDK in house.

Additional context
This is how i am deploying it at the moment:

cloudscanner.ts

import { ICluster, KubernetesManifest } from "aws-cdk-lib/aws-eks";
import { ManagedPolicy } from "aws-cdk-lib/aws-iam";

const serviceName = "deepfence-cloud-scanner";

export function addCloudScanner(stack: Stack, cluster: ICluster, namespace: string, consoleUrl: url): KubernetesManifest {
  const serviceAccount = cluster.addServiceAccount("cloudScannerSA", {
    name: serviceName,
    namespace,
  });

  const policy = ManagedPolicy.fromManagedPolicyArn(stack, "auditPolicy", "arn:aws:iam::aws:policy/SecurityAudit");
  serviceAccount.role.addManagedPolicy(policy);

  return cluster.addManifest("console", {
    apiVersion: "apps/v1",

I understand the need of having cloud-scanner as a part of console/agent deployment. Currently we don't have it, but we can look into it.

@ibreakthecloud @gnmahanth I appreciate you looking into this.

As far as i can see the way i have it running at the moment is working successfully. The only niggle with it is that the Account ID that its showing in the console is the Instance ID of the node the pod is running on.

Is there a way that can be overridden via an environment variable or a command arg or something?

@lumattr thanks for reporting the issue, there is no support for running cloud scanner on kubernetes we are looking into it

Steps to reproduce the issue

• create iam service account using eksctl on existing cluster

export CLUSTER_NAME=<cluster name>
eksctl create iamserviceaccount \
    --name cloud-scanner \
    --namespace cloud-scanner \
    --cluster $CLUSTER_NAME \
    --attach-policy-arn arn:aws:iam::aws:policy/SecurityAudit \
    --attach-policy-arn arn:aws:iam::aws:policy/ReadOnlyAccess \
    --approve \
    --override-existing-serviceaccounts

• apply kuberenetes manifests for cloud scanner

kubectl apply -f cloud-scanner.yaml --namespace cloud-scanner
