It is targeted at operators and developers of security-critical applications, as well as lower-trust users. The following listed controls should be enforced/disallowed\n\nIn this table, wildcards () indicate all elements in a list. For example, spec.containers[].securityContext refers to the Security Context object for _all defined containers_. If any of the listed containers fails to meet the requirements, the entire pod will fail validation.\n\nRestricted policy specification Control Policy Everything from the Baseline policy Volume Types The Restricted policy only permits the following volume types. Restricted Fields spec.volumes[] Allowed Values Every item in the spec.volumes[] list must set one of the following fields to a non-null value: spec.volumes[].configMap spec.volumes[].csi spec.volumes[].downwardAPI spec.volumes[].emptyDir spec.volumes[].ephemeral spec.volumes[].persistentVolumeClaim spec.volumes[].projected spec.volumes[].secret Privilege Escalation (v1.8+) Privilege escalation (such as via set-user-ID or set-group-ID file mode) should not be allowed. This is Linux only policy in v1.25+ (spec.os.name != windows) Restricted Fields spec.containers[].securityContext.allowPrivilegeEscalation spec.initContainers[].securityContext.allowPrivilegeEscalation spec.ephemeralContainers[].securityContext.allowPrivilegeEscalation Allowed Values false Running as Non-root Containers must be required to run as non-root users. Restricted Fields spec.securityContext.runAsNonRoot spec.containers[].securityContext.runAsNonRoot spec.initContainers[].securityContext.runAsNonRoot spec.ephemeralContainers[].securityContext.runAsNonRoot Allowed Values true The container fields may be undefined/nil if the pod-level spec.securityContext.runAsNonRoot is set to true. Running as Non-root user (v1.23+) Containers must not set runAsUser to 0 Restricted Fields spec.securityContext.runAsUser spec.containers[].securityContext.runAsUser spec.initContainers[].securityContext.runAsUser spec.ephemeralContainers[].securityContext.runAsUser Allowed Values any non-zero value undefined/null Seccomp (v1.19+) Seccomp profile must be explicitly set to one of the allowed values. Both the Unconfined profile and the absence of a profile are prohibited. …\n\nAttribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
