Control: ReplicaSet containers should have kube controller manager root CA file configured appropriately

Description

This check ensures that the container in the ReplicaSet has kube controller manager root CA file configured appropriately.

Usage

Run the control in your terminal:

powerpipe control run kubernetes_compliance.control.replicaset_container_argument_kube_controller_manager_root_ca_file_configured

Snapshot and share results via Turbot Pipes:

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

SQL

This control uses a named query:

with container_list as (
select
c ->> 'name' as container_name,
trim('"' from split_part(co::text, '.', 2)) as value,
r.name as replicaset
from
kubernetes_replicaset as r,
jsonb_array_elements(template -> 'spec' -> 'containers') as c,
jsonb_array_elements(c -> 'command') as co
where
(co)::text LIKE '%--root-ca-file%'
), container_name_with_replicaset_name as (
select
r.name as replicaset_name,
r.uid as replicaset_uid,
r.path as path,
r.start_line as start_line,
r.end_line as end_line,
r.context_name as context_name,
r.namespace as namespace,
r.source_type as source_type,
r.tags as tags,
r._ctx as _ctx,
c.*
from
kubernetes_replicaset as r,
jsonb_array_elements(template -> 'spec' -> 'containers') as c
)
select
coalesce(r.replicaset_uid, concat(r.path, ':', r.start_line)) as resource,
case
when (r.value -> 'command') is null or not ((r.value -> 'command') @> '["kube-controller-manager"]') then 'ok'

end as status,
case
when (r.value -> 'command') is null then r.value ->> 'name' || ' command not defined.'
when not ((r.value -> 'command') @> '["kube-controller-manager"]') then r.value ->> 'name' || ' kube-controller-manager not defined.'
when l.container_name is not null and (r.value -> 'command') @> '["kube-controller-manager"]' and ((l.value) like '%pem%') then r.value ->> 'name' || ' root-ca-file is set.'

end as reason,
r.replicaset_name as replicaset_name
, coalesce(context_name, '') as context_name, namespace, source_type, coalesce(path || ':' || start_line || '-' || end_line, '') as path
from
container_name_with_replicaset_name as r
left join container_list as l on r.value ->> 'name' = l.container_name and r.replicaset_name = l.replicaset;
