Control: Replication Controller containers --service-account-key-file argument should be set as appropriate

Description

This check ensures that the container in the Replication Controller has the --service-account-key-file argument set as appropriate.

Usage

Run the control in your terminal:

powerpipe control run kubernetes_compliance.control.replication_controller_container_argument_service_account_key_file_appropriate

Snapshot and share results via Turbot Pipes:

powerpipe login
powerpipe control run kubernetes_compliance.control.replication_controller_container_argument_service_account_key_file_appropriate --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 replication_controller
from
kubernetes_replication_controller as r,
jsonb_array_elements(template -> 'spec' -> 'containers') as c,
jsonb_array_elements_text(c -> 'command') as co
where
co like '%--service-account-key-file=%'
), container_name_with_replication_controller_name as (
select
r.name as replication_controller_name,
r.uid as replication_controller_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,

c.*
from
kubernetes_replication_controller as r,
jsonb_array_elements(template -> 'spec' -> 'containers') as c
)
select
coalesce(r.replication_controller_uid, concat(r.path, ':', r.start_line)) as resource,
case
when (r.value -> 'command') is null or not ((r.value -> 'command') @> '["kube-apiserver"]') then 'ok'
