BUG REPORT

SUMMARY

As pointed out by @thriqon in #285 (comment), kubeaudit audits containers but not initContainers. This is specifically problematic for the apparmor auditor which warns if an apparmor annotation refers to a container that doesn't exist and will remove that annotation in autofix. Since it ignores initContainers this would mean that an apparmor annotation which correctly refers to an initContainer would be removed by kubeaudit. In general though, we should add support for kubeaudit to add security controls to initContainers the same way it does for containers.

ENVIRONMENT

See #285 (comment)

STEPS TO REPRODUCE

See #285 (comment)

EXPECTED RESULTS

Kubeaudit should audit initContainers the same way it audits containers.

ACTUAL RESULTS

Kubeaudit ignores initContainers and removes apparmor annotations that refer to initContainers

ADDITIONAL INFORMATION
