Required

• spec

Specification

Property	Type	Description
apiVersion	string	APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources
kind	string	Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
metadata	ObjectMeta	Standard object’s metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata
spec	object	spec is the specification of the desired behavior of the Machine Config Operator
status	object	status is the most recently observed status of the Machine Config Operator

.spec

Description

spec is the specification of the desired behavior of the Machine Config Operator

Type

`object`

Property	Type	Description
bootImageSkewEnforcement	object	bootImageSkewEnforcement allows an admin to configure how boot image version skew is enforced on the cluster. When omitted, this will default to Automatic for clusters that support automatic boot image updates. For clusters that do not support automatic boot image updates, cluster upgrades will be disabled until a skew enforcement mode has been specified. When version skew is being enforced, cluster upgrades will be disabled until the version skew is deemed acceptable for the current release payload.
failedRevisionLimit	integer	failedRevisionLimit is the number of failed static pod installer revisions to keep on disk and in the api -1 = unlimited, 0 or unset = 5 (default)
forceRedeploymentReason	string	forceRedeploymentReason can be used to force the redeployment of the operand by providing a unique string. This provides a mechanism to kick a previously failed deployment and provide a reason why you think it will work this time instead of failing again on the same config.
logLevel	string	logLevel is an intent based logging for an overall component. It does not give fine grained control, but it is a simple way to manage coarse grained logging choices that operators have to interpret for their operands. Valid values are: "Normal", "Debug", "Trace", "TraceAll". Defaults to "Normal".
managedBootImages	object	managedBootImages allows configuration for the management of boot images for machine resources within the cluster. This configuration allows users to select resources that should be updated to the latest boot images during cluster upgrades, ensuring that new machines always boot with the current cluster version’s boot image. When omitted, this means no opinion and the platform is left to choose a reasonable default, which is subject to change over time. The default for each machine manager mode is All for GCP and AWS platforms, and None for all other platforms.
managementState	string	managementState indicates whether and how the operator should manage the component
nodeDisruptionPolicy	object	nodeDisruptionPolicy allows an admin to set granular node disruption actions for MachineConfig-based updates, such as drains, service reloads, etc. Specifying this will allow for less downtime when doing small configuration updates to the cluster. This configuration has no effect on cluster upgrades which will still incur node disruption where required.
observedConfig	``	observedConfig holds a sparse config that controller has observed from the cluster state. It exists in spec because it is an input to the level for the operator
operatorLogLevel	string	operatorLogLevel is an intent based logging for the operator itself. It does not give fine grained control, but it is a simple way to manage coarse grained logging choices that operators have to interpret for themselves. Valid values are: "Normal", "Debug", "Trace", "TraceAll". Defaults to "Normal".
succeededRevisionLimit	integer	succeededRevisionLimit is the number of successful static pod installer revisions to keep on disk and in the api -1 = unlimited, 0 or unset = 5 (default)
unsupportedConfigOverrides	``	unsupportedConfigOverrides overrides the final configuration that was computed by the operator. Red Hat does not support the use of this field. Misuse of this field could lead to unexpected behavior or conflict with other configuration options. Seek guidance from the Red Hat support before using this field. Use of this property blocks cluster upgrades, it must be removed before upgrading your cluster.

.spec.bootImageSkewEnforcement

Description

bootImageSkewEnforcement allows an admin to configure how boot image version skew is enforced on the cluster. When omitted, this will default to Automatic for clusters that support automatic boot image updates.

When version skew is being enforced, cluster upgrades will be disabled until the version skew is deemed acceptable for the current release payload.

In Manual mode, the MCO will prevent upgrades when the boot image skew exceeds the skew limit described by the release image. None means that the MCO will no longer monitor the boot image skew. This may affect the cluster’s ability to scale. This field is required.

fieldValidation	string	fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields. Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields.
