Chapter 23. MachineConfiguration [operator.openshift.io/v1]

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.

irreconcilableValidationOverrides

object

irreconcilableValidationOverrides is an optional field that can used to make changes to a MachineConfig that cannot be applied to existing nodes. When specified, the fields configured with validation overrides will no longer reject changes to those respective fields due to them not being able to be applied to existing nodes. Only newly provisioned nodes will have these configurations applied. Existing nodes will report observed configuration differences in their MachineConfigNode status.

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.

manual

object

manual describes the current boot image of the cluster. This should be set to the oldest boot image used amongst all machine resources in the cluster. This must include either the RHCOS version of the boot image or the OCP release version which shipped with that RHCOS boot image. Required when mode is set to "Manual" and forbidden otherwise.

mode

string

mode determines the underlying behavior of skew enforcement mechanism. Valid values are Manual and None. Manual means that the cluster admin is expected to perform manual boot image updates and store the OCP & RHCOS version associated with the last boot image update in the manual field. 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.

mode

string

mode is used to configure which boot image field is defined in Manual mode. Valid values are OCPVersion and RHCOSVersion. OCPVersion means that the cluster admin is expected to set the OCP version associated with the last boot image update in the OCPVersion field. RHCOSVersion means that the cluster admin is expected to set the RHCOS version associated with the last boot image update in the RHCOSVersion field. This field is required.

ocpVersion

string

ocpVersion provides a string which represents the OCP version of the boot image. This field must match the OCP semver compatible format of x.y.z. This field must be between 5 and 10 characters long. Required when mode is set to "OCPVersion" and forbidden otherwise.

rhcosVersion

string

rhcosVersion provides a string which represents the RHCOS version of the boot image This field must match rhcosVersion formatting of [major].[minor].[datestamp(YYYYMMDD)]-[buildnumber] or the legacy format of [major].[minor].[timestamp(YYYYMMDDHHmm)]-[buildnumber]. This field must be between 14 and 21 characters long. Required when mode is set to "RHCOSVersion" and forbidden otherwise.

When contains "FileSystems" changes to the spec.config.storage.filesystems section of MachineConfig CRs are allowed. When contains "Raid" changes to the spec.config.storage.raid section of MachineConfig CRs are allowed. When omitted changes to the spec.config.storage section are forbidden.

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. The error returned from the server will contain all unknown and duplicate fields encountered.

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. The error returned from the server will contain all unknown and duplicate fields encountered.
