Instance Attribute Details

#allowed_unsafe_sysctls ⇒ Array<String>

Optional. Defines a comma-separated allowlist of unsafe sysctls or sysctl patterns (ending in *). The unsafe namespaced sysctl groups are kernel.shm* , kernel.msg*, kernel.sem, fs.mqueue.*, and net.*. Leaving this allowlist empty means they cannot be set on Pods. To allow certain sysctls or sysctl patterns to be set on Pods, list them separated by commas. For example: kernel.msg*,net.ipv4.route.min_pmtu. See https://kubernetes.io/docs/tasks/ administer-cluster/sysctl-cluster/ for more details. Corresponds to the JSON property allowedUnsafeSysctls

Returns:

  • (Array<String>)
