This chart contains Kyverno's implementation of the Kubernetes Pod Security Standards (PSS) as documented at https://kubernetes.io/docs/concepts/security/pod-security-standards/ and are a Helm packaged version of those found at https://github.com/kyverno/policies/tree/main/pod-security. The goal of the PSS controls is to provide a good starting point for general Kubernetes cluster operational security. These controls are broken down into two categories, Baseline and Restricted. Baseline policies implement the most basic of Pod security controls while Restricted implements more strict controls. Restricted is cumulative and encompasses those listed in Baseline.
The following policies are included in each profile.
**Baseline**
* disallow-capabilities
* disallow-host-namespaces
* disallow-host-path
* disallow-host-ports
* disallow-host-process
* disallow-privileged-containers
* disallow-proc-mount
* disallow-selinux
* restrict-apparmor-profiles
* restrict-seccomp
* restrict-sysctls
**Restricted**
* disallow-capabilities-strict
* disallow-privilege-escalation
* require-run-as-non-root-user
* require-run-as-nonroot
* restrict-seccomp-strict
* restrict-volume-types
An additional policy "require-non-root-groups" is included in an `other` group as this was previously included in the official PSS controls but since removed.
For the latest version of these PSS policies, always refer to the kyverno/policies repo at https://github.com/kyverno/policies/tree/main/pod-security.
| policyKind | string | `"ClusterPolicy"` | Policy kind (`ClusterPolicy`, `Policy`) Set to `Policy` if you need namespaced policies and not cluster policies |
| podSecurityStandard | string | `"baseline"` | Pod Security Standard profile (`baseline`, `restricted`, `privileged`, `custom`). For more info https://kyverno.io/policies/pod-security. |
| podSecuritySeverity | string | `"medium"` | Pod Security Standard (`low`, `medium`, `high`). |
| podSecurityPolicies | list | `[]` | Policies to include when `podSecurityStandard` is `custom`. |
| includeOtherPolicies | list | `[]` | Additional policies to include from `other`. |
| failurePolicy | string | `"Fail"` | API server behavior if the webhook fails to respond ('Ignore', 'Fail') For more info: https://kyverno.io/docs/writing-policies/policy-settings/ |
| validationFailureActionByPolicy | object | `{}` | Define validationFailureActionByPolicy for specific policies. Override the defined `validationFailureAction` with a individual validationFailureAction for individual Policies. |
| validationFailureActionOverrides | object | `{"all":[]}` | Define validationFailureActionOverrides for specific policies. The overrides for `all` will apply to all policies. |
| policyExclude | object | `{}` | Exclude resources from individual policies. Policies with multiple rules can have individual rules excluded by using the name of the rule as the key in the `policyExclude` map. |
| policyPreconditions | object | `{}` | Add preconditions to individual policies. Policies with multiple rules can have individual rules excluded by using the name of the rule as the key in the `policyPreconditions` map. |
| autogenControllers | string | `""` | Customize the target Pod controllers for the auto-generated rules. (Eg. `none`, `Deployment`, `DaemonSet,Deployment,StatefulSet`) For more info https://kyverno.io/docs/writing-policies/autogen/. |
| kyvernoVersion | string | `"autodetect"` | Kyverno version The default of "autodetect" will try to determine the currently installed version from the deployment |
