Snapshot and share results via Turbot Pipes:

powerpipe control run kubernetes_compliance.control.pod_container_argument_service_account_key_file_appropriate --share

SQL

This control uses a named query:

select
c ->> 'name' as container_name,
trim('"' from split_part(co::text, '=', 2)) as value,
p.name as pod
from
kubernetes_pod as p,

jsonb_array_elements_text(c -> 'command') as co
where
co like '%--service-account-key-file=%'

coalesce(p.pod_uid, concat(p.path, ':', p.start_line)) as resource,
