Unsafe kernel parameters configured in containersKUBELIN-W1046
Major
Anti-patternAlert on deployments specifying unsafe sysctls that may lead to severe problems like wrong behavior of containers
Remediation
Ensure that containers do not allow unsafe allocation of system resources by removing unsafe kernel parameter configurations. For more details, see https://kubernetes.io/docs/tasks/administer-cluster/sysctl-cluster/ and https://docs.docker.com/engine/reference/commandline/run/#configure-namespaced-kernel-parameters-sysctls-at-runtime.
