# Kubernetes Reporter Helm Chart

> A Helm chart for installing the Kosli K8S reporter as a cronjob.

# k8s-reporter

<Info>
  This reference applies to **chart version 2.3.1**, which defaults to CLI **v2.12.0** via `appVersion`. Override with `image.tag`.
</Info>

A Helm chart for installing the Kosli K8S reporter as a CronJob.
The chart allows you to create a Kubernetes cronjob and all its necessary RBAC to report running images to Kosli at a given cron schedule.

Configuration is done via **reporterConfig.environments**: a list of Kosli environments to report to. Each entry has a required `name` and optional namespace selectors. Use one entry for a single environment, or multiple entries to report to different environments with different selectors.

## Breaking change in v2.0.0

Version 2.0.0 removes the previous single-environment mode (`kosliEnvironmentName` and the `namespaces` / `namespacesRegex` / `excludeNamespaces` / `excludeNamespacesRegex` flags). You now configure one or more environments only via **reporterConfig.environments**. To report a single environment, use a list with one entry.

## Prerequisites

* A Kubernetes cluster (minimum supported version is `v1.21`)
* Helm v3.0+
* If you want to report artifacts from just one namespace, you need to have permissions to `get` and `list` pods in that namespace.
* If you want to report artifacts from multiple namespaces or entire cluster, you need to have cluster-wide permissions to `get` and `list` pods.

## Installing the chart

To install this chart via the Helm chart repository:

<Steps>
  <Step title="Add the Kosli helm repo">
    ```shell theme={"theme":"dracula","languages":{"custom":["/languages/rego.json"]}}
    helm repo add kosli https://charts.kosli.com/ && helm repo update
    ```
  </Step>

  <Step title="Create a secret for the Kosli API token">
    ```shell theme={"theme":"dracula","languages":{"custom":["/languages/rego.json"]}}
    kubectl create secret generic kosli-api-token --from-literal=key=<your-api-key>
    ```
  </Step>

  <Step title="Install the helm chart">
    Configure **reporterConfig.environments** (required). Each entry has required `name` and optional `namespaces`, `namespacesRegex`, `excludeNamespaces`, `excludeNamespacesRegex`. Omit namespace fields for an entry to report the entire cluster to that environment.

    **One environment, entire cluster:**

    ```yaml theme={"theme":"dracula","languages":{"custom":["/languages/rego.json"]}}
    # values.yaml
    reporterConfig:
      kosliOrg: <your-org>
      environments:
        - name: <your-env-name>
    ```

    **One environment, specific namespaces:**

    ```yaml theme={"theme":"dracula","languages":{"custom":["/languages/rego.json"]}}
    reporterConfig:
      kosliOrg: <your-org>
      environments:
        - name: <your-env-name>
          namespaces: [namespace1, namespace2]
    ```

    **Multiple environments with different selectors:**

    ```yaml theme={"theme":"dracula","languages":{"custom":["/languages/rego.json"]}}
    reporterConfig:
      kosliOrg: <your-org>
      environments:
        - name: prod-env
          namespaces: [prod-ns1, prod-ns2]
        - name: staging-env
          namespacesRegex: ["^staging-.*"]
        - name: infra-env
          excludeNamespaces: [prod-ns1, prod-ns2, default]
    ```

    ```shell theme={"theme":"dracula","languages":{"custom":["/languages/rego.json"]}}
    helm install kosli-reporter kosli/k8s-reporter -f values.yaml
    ```
  </Step>
</Steps>

<Info>See all available [configuration options](#configurations) below.</Info>

## Upgrading the chart

If upgrading from v1.x to v2.0.0, migrate your values to the **environments** list format (see above). Then:

```shell theme={"theme":"dracula","languages":{"custom":["/languages/rego.json"]}}
helm upgrade kosli-reporter kosli/k8s-reporter -f values.yaml
```

## Uninstalling chart

```shell theme={"theme":"dracula","languages":{"custom":["/languages/rego.json"]}}
helm uninstall kosli-reporter
```

## Running behind a TLS-inspecting proxy (corporate / custom CA bundle)

If your network sits behind a TLS-inspecting appliance (Zscaler, Netskope, Palo Alto, etc.) that re-signs HTTPS traffic with a corporate CA certificate, the reporter will fail with `x509: certificate signed by unknown authority`. To fix this, make the appliance's CA bundle available to the reporter.

The chart offers two ways to do this. Use whichever fits your deployment flow.

### Option 1 — customCA convenience wrapper (recommended for the common case)

<Steps>
  <Step title="Create a Secret containing the corporate CA certificate">
    PEM format, single cert or bundle:

    ```shell theme={"theme":"dracula","languages":{"custom":["/languages/rego.json"]}}
    kubectl create secret generic corporate-ca-bundle --from-file=ca.crt=/path/to/corporate-ca.crt
    ```
  </Step>

  <Step title="Enable the wrapper in values.yaml">
    ```yaml theme={"theme":"dracula","languages":{"custom":["/languages/rego.json"]}}
    customCA:
      enabled: true
      secretName: corporate-ca-bundle
      key: ca.crt
    ```
  </Step>
</Steps>

The chart mounts the certificate as a single file at `/etc/ssl/certs/kosli-custom-ca.crt` using `subPath`. Go's standard library on Linux loads CA roots in two independent passes — it reads the system bundle file (e.g. `/etc/ssl/certs/ca-certificates.crt`) and **also** scans `/etc/ssl/certs/` for additional certificate files. The mounted file is picked up by the directory scan and added to the trust store alongside the system roots, so no `SSL_CERT_FILE` env var is needed.

The wrapper deliberately does **not** set `SSL_CERT_FILE`. Setting it would replace the system bundle entirely with the customer's file, breaking trust for any public CAs the bundle does not include.

### Option 2 — generic extraVolumes / extraVolumeMounts / extraEnvVars

Use these when you need a non-default mount path, a ConfigMap instead of a Secret, multiple volumes, or any other shape the wrapper does not cover:

```yaml theme={"theme":"dracula","languages":{"custom":["/languages/rego.json"]}}
extraVolumes:
  - name: corporate-ca
    secret:
      secretName: corporate-ca-bundle

extraVolumeMounts:
  - name: corporate-ca
    mountPath: /etc/ssl/certs/corporate
    readOnly: true
```

<Warning>
  If you mount the CA outside `/etc/ssl/certs/` and set `SSL_CERT_FILE` via `extraEnvVars`, your bundle must include the public CAs you also need to trust — Go uses only that file when `SSL_CERT_FILE` is set.
</Warning>

### Pod Security Standards

Both options use `secret`-backed volumes, which are permitted under the Pod Security Standards `restricted` profile. `hostPath` mounts are not permitted under that profile and should not be used here.

### Cluster-wide alternative

If you already run [cert-manager's trust-manager](https://cert-manager.io/docs/trust/trust-manager/) to distribute a corporate CA bundle into a well-known ConfigMap in every namespace, point `extraVolumes` / `extraVolumeMounts` at that ConfigMap instead of creating a per-namespace Secret.

## Running on EKS with Karpenter (or another node autoscaler)

By default the reporter runs as a CronJob every 5 minutes. On clusters that use [Karpenter](https://karpenter.sh) for node autoscaling, this frequent scheduling can prevent nodes from being **consolidated** (scaled down).

The cause is Karpenter's `consolidateAfter` timer: Karpenter only consolidates a node once it has seen no pod scheduling activity on it for the configured window. A reporter pod arriving every 5 minutes keeps resetting that timer, so any node whose `consolidateAfter` is longer than the reporter interval never becomes eligible for consolidation (see [karpenter#1921](https://github.com/kubernetes-sigs/karpenter/issues/1921)). This is Karpenter working as designed, not a reporter bug.

Frequent snapshots are what let Kosli surface drift or an unauthorized change quickly, so the best fix keeps the 5-minute cadence and moves the reporter out of Karpenter's way. Widening the interval trades away that detection speed and should be a last resort.

### 1. Pin the reporter to a stable node group (recommended)

If you run a stable managed node group that Karpenter does not manage, schedule the reporter there so it never disturbs Karpenter-managed nodes. Use `nodeSelector`, and `tolerations` if that node group is tainted:

```yaml theme={"theme":"dracula","languages":{"custom":["/languages/rego.json"]}}
nodeSelector:
  eks.amazonaws.com/nodegroup: system   # your managed node group

tolerations:
  - key: dedicated
    operator: Equal
    value: system
    effect: NoSchedule
```

To steer the reporter away from Karpenter-managed nodes instead, use `affinity` (a plain `nodeSelector` cannot express "not on these nodes"):

```yaml theme={"theme":"dracula","languages":{"custom":["/languages/rego.json"]}}
affinity:
  nodeAffinity:
    requiredDuringSchedulingIgnoredDuringExecution:
      nodeSelectorTerms:
        - matchExpressions:
            - key: karpenter.sh/nodepool
              operator: DoesNotExist
```

### 2. Run the reporter out of the cluster

For zero footprint on cluster nodes, run `kosli snapshot k8s` on a schedule outside the cluster (for example a CI cron job) with kubeconfig access, keeping your reporting cadence without placing a pod on the cluster's nodes. See the [Kubernetes environment reporting tutorial](/tutorials/report_k8s_envs).

### 3. Widen the report interval (last resort)

Only if you cannot pin the reporter or move it out of cluster: set `cronSchedule` longer than your NodePool's `consolidateAfter` so nodes get quiet windows long enough to consolidate. This works, but a longer interval widens the window in which a change can go unreported, so prefer the options above.

```yaml theme={"theme":"dracula","languages":{"custom":["/languages/rego.json"]}}
cronSchedule: "*/15 * * * *"
```

<Warning>
  `karpenter.sh/do-not-disrupt: "true"` is **not** a fix here. It prevents Karpenter from disrupting the pod, which protects a mid-run report from interruption but makes consolidation of that node *less* likely, not more. Likewise `cluster-autoscaler.kubernetes.io/safe-to-evict` only affects the Kubernetes Cluster Autoscaler and is ignored by Karpenter.
</Warning>
