get hardening policies for `replicasets`, `statefulsets` & `daemonsets` #681

Prateeknandle · 2023-03-09T11:41:13Z

fixes #670

changes:

getting replicasets, daemonsets and statefulsets from k8s client and generating hardening policies respectively
updating clusterRole for the same
added test cases to test whether we get the hardening policy or not

LGTM!

@Prateeknandle Can we update the helm chart as well to match the ClusterRole ?

can we merge the pr?

can we merge the pr?

The test is failing!

nyrahul · 2023-03-10T07:42:05Z

Can we add a testcase to test this?

Prateeknandle · 2023-03-10T14:05:18Z

Can we add a testcase to test this?

tests for recommend are defined in kubearmor-client

The test is failing!

it's because the tests are flaky

For testing whether changes are working or not we can see logs

vishnusomank

LGTM!

Tested by deploying via deployment.yaml and helm. The code changes are able to detect and generate policies for Statefulset and Replicaset.
Only issue is if a new replicaset or statefulset is deployed we'll have to wait for the cronjob to trigger (every 1 hour) to get hardening policies for those.

Prateeknandle · 2023-03-22T01:25:09Z

With the new changes I've checked locally, tests are passing and discovery-engine is able to get the hardening policies.

the ginkgo test which are failing are the flaky ones and not related to this pr.

I think we should handle daemonsets as well in this. @Ankurk99 what do you think?

Mostly good. Just one small fix.

@vishnusomank , can you provide your approval?

+		for _, ns := range nsNotFilter {
 			if d.Namespace != ns {
 				generateHardenPolicy(d.Name, d.Namespace, d.Spec.Template.Labels)


We are already generating policies for Deployments here. Why are we generating them again at line 150? It should be in a single place only.

Vyom-Yadav · 2023-04-25T20:01:52Z

src/recommendpolicy/recommendPolicy.go

+	if !isLatest() {
+		version, err := DownloadAndUnzipRelease()
+		if err != nil {
+			log.Error().Msgf("Unable to download %v", err.Error())
+			return nil
+		}
+		log.Info().Msgf("Downloaded version: %v", version)
+	}


This should not be clubbed with GetHardenPolicy(...). Downloading and unzipping release is a separate process. Policy templates are required for both KubeArmor and Kyverno policies.
