Chapter 12. Etcd [operator.openshift.io/v1] Description Etcd provides information to configure an operator to manage etcd. 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 12.1. 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#metadata spec object status object 12.1.1. .spec Description Type object Property Type Description controlPlaneHardwareSpeed string HardwareSpeed allows user to change the etcd tuning profile which configures the latency parameters for heartbeat interval and leader election timeouts allowing the cluster to tolerate longer round-trip-times between etcd members. Valid values are "", "Standard" and "Slower". "" means no opinion and the platform is left to choose a reasonable default which is subject to change without notice. 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". managementState string managementState indicates whether and how the operator should manage the component 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. 12.1.2. .status Description Type object Property Type Description conditions array conditions is a list of conditions and their status conditions[] object OperatorCondition is just the standard condition fields. controlPlaneHardwareSpeed string ControlPlaneHardwareSpeed declares valid hardware speed tolerance levels generations array generations are used to determine when an item needs to be reconciled or has changed in a way that needs a reaction. generations[] object GenerationStatus keeps track of the generation for a given resource so that decisions about forced updates can be made. latestAvailableRevision integer latestAvailableRevision is the deploymentID of the most recent deployment latestAvailableRevisionReason string latestAvailableRevisionReason describe the detailed reason for the most recent deployment nodeStatuses array nodeStatuses track the deployment values and errors across individual nodes nodeStatuses[] object NodeStatus provides information about the current state of a particular node managed by this operator. observedGeneration integer observedGeneration is the last generation change you've dealt with readyReplicas integer readyReplicas indicates how many replicas are ready and at the desired state version string version is the level this availability applies to 12.1.3. .status.conditions Description conditions is a list of conditions and their status Type array 12.1.4. .status.conditions[] Description OperatorCondition is just the standard condition fields. Type object Required lastTransitionTime status type Property Type Description lastTransitionTime string lastTransitionTime is the last time the condition transitioned from one status to another. This should be when the underlying condition changed. If that is not known, then using the time when the API field changed is acceptable. message string reason string status string status of the condition, one of True, False, Unknown. type string type of condition in CamelCase or in foo.example.com/CamelCase. 12.1.5. .status.generations Description generations are used to determine when an item needs to be reconciled or has changed in a way that needs a reaction. Type array 12.1.6. .status.generations[] Description GenerationStatus keeps track of the generation for a given resource so that decisions about forced updates can be made. Type object Required group name namespace resource Property Type Description group string group is the group of the thing you're tracking hash string hash is an optional field set for resources without generation that are content sensitive like secrets and configmaps lastGeneration integer lastGeneration is the last generation of the workload controller involved name string name is the name of the thing you're tracking namespace string namespace is where the thing you're tracking is resource string resource is the resource type of the thing you're tracking 12.1.7. .status.nodeStatuses Description nodeStatuses track the deployment values and errors across individual nodes Type array 12.1.8. .status.nodeStatuses[] Description NodeStatus provides information about the current state of a particular node managed by this operator. Type object Required nodeName Property Type Description currentRevision integer currentRevision is the generation of the most recently successful deployment lastFailedCount integer lastFailedCount is how often the installer pod of the last failed revision failed. lastFailedReason string lastFailedReason is a machine readable failure reason string. lastFailedRevision integer lastFailedRevision is the generation of the deployment we tried and failed to deploy. lastFailedRevisionErrors array (string) lastFailedRevisionErrors is a list of human readable errors during the failed deployment referenced in lastFailedRevision. lastFailedTime string lastFailedTime is the time the last failed revision failed the last time. lastFallbackCount integer lastFallbackCount is how often a fallback to a revision happened. nodeName string nodeName is the name of the node targetRevision integer targetRevision is the generation of the deployment we're trying to apply 12.2.
