Miscellaneous

Context Filtering

Prowler will scan the active Kubernetes context by default.

To specify the Kubernetes context to be scanned, use the --context flag followed by the desired context name. For example:

prowler --context my-context

This will ensure that Prowler scans the specified context/cluster for vulnerabilities and misconfigurations.

Namespace Filtering

By default, prowler will scan all namespaces in the context you specify.

To specify the namespace(s) to be scanned, use the --namespace flag followed by the desired namespace(s) separated by spaces. For example:

prowler --namespace namespace1 namespace2

Proxy and TLS Verification

If your Kubernetes cluster is only accessible via an internal proxy, Prowler will respect the HTTPS_PROXY or https_proxy environment variable:

export HTTPS_PROXY=http://my.internal.proxy:8888
prowler kubernetes ...

If you need to skip TLS verification for internal proxies, you can set the K8S_SKIP_TLS_VERIFY environment variable:

export K8S_SKIP_TLS_VERIFY=true
prowler kubernetes ...

This will allow Prowler to connect to the cluster even if the proxy uses a self-signed certificate.

These environment variables are supported both when using an external kubeconfig and in in-cluster mode.
