Control: ReplicaSet containers argument admission control plugin where either PodSecurityPolicy or SecurityContextDeny should be enabled

Description

This check ensures that the container in the ReplicaSet has argument admission control plugin where either PodSecurityPolicy or SecurityContextDeny is enabled.

Usage

Run the control in your terminal:

powerpipe control run kubernetes_compliance.control.replicaset_container_argument_security_context_deny_enabled

Snapshot and share results via Turbot Pipes:

powerpipe login
powerpipe control run kubernetes_compliance.control.replicaset_container_argument_security_context_deny_enabled --share

SQL

This control uses a named query:

select
coalesce(uid, concat(path, ':', start_line)) as resource,
case
when (c -> 'command') is null or not ((c -> 'command') @> '["kube-apiserver"]') then 'ok'
when (c -> 'command') @> '["kube-apiserver"]'
and ((c -> 'command') @> '["--enable-admission-plugins=PodSecurityPolicy"]' or (c -> 'command') @> '["--enable-admission-plugins=SecurityContextDeny"]') then 'ok'
else 'alarm'
end as status,
case
when (c -> 'command') is null then c ->> 'name' || ' command not defined.'
when not ((c -> 'command') @> '["kube-apiserver"]') then c ->> 'name' || ' kube-apiserver not defined.'
when (c -> 'command') @> '["kube-apiserver"]'
and (c -> 'command') @> '["--enable-admission-plugins=PodSecurityPolicy"]' then c ->> 'name' || ' has admission control plugin PodSecurityPolicy enabled.'
when (c -> 'command') @> '["kube-apiserver"]'
and (c -> 'command') @> '["--enable-admission-plugins=SecurityContextDeny"]' then c ->> 'name' || ' has admission control plugin SecurityContextDeny enabled.'
else c ->> 'name' || ' has admission control plugin PodSecurityPolicy and SecurityContextDeny disabled.'
end as reason,
name as replicaset_name
, coalesce(context_name, '') as context_name, namespace, source_type, coalesce(path || ':' || start_line || '-' || end_line, '') as path
from
kubernetes_replicaset,
jsonb_array_elements(template -> 'spec' -> 'containers') as c;
