SQL
This control uses a named query:
select distinct(coalesce(n.uid, concat(n.path, ':', n.start_line))) as resource, case when q.spec_hard -> 'limits.memory' is null then 'alarm' else 'ok' end as status, case when q.spec_hard -> 'limits.memory' is null then n.name || ' do not have ResourceQuota for memory limit.' else n.name || ' have ResourceQuota for memory limit.' end as reason , coalesce(n.context_name, '') as context_name, n.name, n.source_type, coalesce(n.path || ':' || n.start_line || '-' || n.end_line, '') as pathfrom kubernetes_namespace n left join kubernetes_resource_quota q on n.name = q.namespace;
