Control: Deployment containers should have kubelet terminated pod gc threshold configured appropriately

Description

This check ensures that the container in the Deployment has kubelet terminated pod gc threshold configured appropriately.

Usage

Run the control in your terminal:

powerpipe control run kubernetes_compliance.control.deployment_container_argument_kubelet_terminated_pod_gc_threshold_configured

Snapshot and share results via Turbot Pipes:

powerpipe login
powerpipe control run kubernetes_compliance.control.deployment_container_argument_kubelet_terminated_pod_gc_threshold_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))::integer as value,
d.name as deployment
from
kubernetes_deployment as d,
jsonb_array_elements(template -> 'spec' -> 'containers') as c,
jsonb_array_elements(c -> 'command') as co
where
(co)::text LIKE '%--terminated-pod-gc-threshold=%'
), container_name_with_deployment_name as (
select
d.name as deployment_name,
d.uid as deployment_uid,
d.path as path,
d.start_line as start_line,
d.end_line as end_line,
d.context_name as context_name,
d.namespace as namespace,
d.source_type as source_type,
d.tags as tags,
d._ctx as _ctx,
c.*
from
kubernetes_deployment as d,
jsonb_array_elements(template -> 'spec' -> 'containers') as c
)
select
coalesce(d.deployment_uid, concat(d.path, ':', d.start_line)) as resource,
case
when (d.value -> 'command') is null or not ((d.value -> 'command') @> '["kubelet"]') then 'ok'
when l.container_name is not null and (d.value -> 'command') @> '["kubelet"]' and (l.value = 0) then 'ok'
else 'alarm'
end as status,
case
when (d.value -> 'command') is null then d.value ->> 'name' || ' command not defined.'
when not ((d.value -> 'command') @> '["kubelet"]') then d.value ->> 'name' || ' kubelet not defined.'
when l.container_name is not null and (d.value -> 'command') @> '["kubelet"]' and coalesce((l.value)::int, 0) > 0 then d.value ->> 'name' || ' kubelet terminated pod gc threshold is set to ' || (l.value) || '.'
else d.value ->> 'name' || ' kubelet terminated pod gc threshold is not set apropriately.'
end as reason,
d.deployment_name as deployment_name
, coalesce(context_name, '') as context_name, namespace, source_type, coalesce(path || ':' || start_line || '-' || end_line, '') as path
from
container_name_with_deployment_name as d
left join container_list as l on d.value ->> 'name' = l.container_name and d.deployment_name = l.deployment;
