#allowed_unsafe_sysctls ⇒ ::Array<::String>

Returns 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.

#container_log_max_size ⇒ ::String

Returns Optional. Defines the maximum size of the container log file before it is rotated. See https://kubernetes.io/docs/concepts/cluster-administration/logging/#log-rotation

Valid format is positive number + unit, e.g. 100Ki, 10Mi. Valid units are Ki, Mi, Gi. The value must be between 10Mi and 500Mi, inclusive.

Note that the total container log size (container_log_max_size * container_log_max_files) cannot exceed 1% of the total storage of the node, to avoid disk pressure caused by log files.

The default value is 10Mi if unspecified.

#cpu_cfs_quota ⇒ ::Google::Protobuf::BoolValue

Returns Enable CPU CFS quota enforcement for containers that specify CPU limits.

This option is enabled by default which makes kubelet use CFS quota (https://www.kernel.org/doc/Documentation/scheduler/sched-bwc.txt) to enforce container CPU limits. Otherwise, CPU limits will not be enforced at all.

Disable this option to mitigate CPU throttling problems while still having your pods to be in Guaranteed QoS class by specifying the CPU limits.

The default value is 'true' if unspecified.
