SQL

This control uses a named query:

select
coalesce(uid, concat(path, ':', start_line)) as resource,
case
when (c -> 'command') is null or not ((c -> 'command') @> '["kube-controller-manager"]' or (c -> 'command') @> '["kubelet"]') then 'ok'
when ((c -> 'command') @> '["kube-controller-manager"]' or (c -> 'command') @> '["kubelet"]')
and (c -> 'command') @> '["--feature-gates=RotateKubeletServerCertificate=true"]' then 'ok'
else 'alarm'
end as status,
case
when (c -> 'command') is null then c ->> 'name' || ' command not defined.'
when (c -> 'command') is null or not ((c -> 'command') @> '["kube-controller-manager"]' or (c -> 'command') @> '["kubelet"]') then c ->> 'name' || 'kube-controller-manager or kubelet not defined'
when ((c -> 'command') @> '["kube-controller-manager"]' or (c -> 'command') @> '["kubelet"]')
and (c -> 'command') @> '["--feature-gates=RotateKubeletServerCertificate=true"]' then c ->> 'name' || ' RotateKubeletServerCertificate argument enabled.'
else c ->> 'name' || ' RotateKubeletServerCertificate argument disabled.'
end as reason,
name as job_name
, coalesce(context_name, '') as context_name, namespace, source_type, coalesce(path || ':' || start_line || '-' || end_line, '') as path
from
kubernetes_job,
jsonb_array_elements(template -> 'spec' -> 'containers') as c;
