Chapter 21. MachineConfiguration [operator.openshift.io/v1] Description MachineConfiguration provides information to configure an operator to manage Machine Configuration. Compatibility level 1: Stable within a major release for a minimum of 12 months or 3 minor releases (whichever is longer). Type object Required spec 21.1. 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 21.1.1. .spec Description spec is the specification of the desired behavior of the Machine Config Operator Type object Property Type Description 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, no boot images will be updated. 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. 21.1.2. .spec.managedBootImages Description 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, no boot images will be updated. Type object Property Type Description machineManagers array machineManagers can be used to register machine management resources for boot image updates. The Machine Config Operator will watch for changes to this list. Only one entry is permitted per type of machine management resource. machineManagers[] object MachineManager describes a target machine resource that is registered for boot image updates. It stores identifying information such as the resource type and the API Group of the resource. It also provides granular control via the selection field. 21.1.3. .spec.managedBootImages.machineManagers Description machineManagers can be used to register machine management resources for boot image updates. The Machine Config Operator will watch for changes to this list. Only one entry is permitted per type of machine management resource. Type array 21.1.4. .spec.managedBootImages.machineManagers[] Description MachineManager describes a target machine resource that is registered for boot image updates. It stores identifying information such as the resource type and the API Group of the resource. It also provides granular control via the selection field. Type object Required apiGroup resource selection Property Type Description apiGroup string apiGroup is name of the APIGroup that the machine management resource belongs to. The only current valid value is machine.openshift.io. machine.openshift.io means that the machine manager will only register resources that belong to OpenShift machine API group. resource string resource is the machine management resource's type. The only current valid value is machinesets. machinesets means that the machine manager will only register resources of the kind MachineSet. selection object selection allows granular control of the machine management resources that will be registered for boot image updates. 21.1.5. .spec.managedBootImages.machineManagers[].selection Description selection allows granular control of the machine management resources that will be registered for boot image updates. Type object Required mode Property Type Description mode string mode determines how machine managers will be selected for updates. Valid values are All and Partial. All means that every resource matched by the machine manager will be updated. Partial requires specified selector(s) and allows customisation of which resources matched by the machine manager will be updated. partial object partial provides label selector(s) that can be used to match machine management resources. Only permitted when mode is set to "Partial". 21.1.6. .spec.managedBootImages.machineManagers[].selection.partial Description partial provides label selector(s) that can be used to match machine management resources. Only permitted when mode is set to "Partial".

Query parameters Parameter Type Description dryRun string When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed 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. This is the default in v1.23+ - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present.
