18.1. Specification
Property | Type | Description |
---|---|---|
|
| 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 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 |
| Standard object’s metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata | |
|
| spec is the specification of the desired behavior of the Kubernetes Controller Manager |
|
| status is the most recently observed status of the Kubernetes Controller Manager |

Property | Type | Description |
---|---|---|
|
| 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 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 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 indicates whether and how the operator should manage the component |
| `` | 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 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 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 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. |
|
| useMoreSecureServiceCA indicates that the service-ca.crt provided in SA token volumes should include only enough certificates to validate service serving certificates. Once set to true, it cannot be set to false. Even if someone finds a way to set it back to false, the service-ca.crt files that previously existed will only have the more secure content. |
18.1.2. .status

|
| conditions is a list of conditions and their status |
|
| OperatorCondition is just the standard condition fields. |
|
| generations are used to determine when an item needs to be reconciled or has changed in a way that needs a reaction. |
|
| GenerationStatus keeps track of the generation for a given resource so that decisions about forced updates can be made. |
|
| latestAvailableRevision is the deploymentID of the most recent deployment |
|
| latestAvailableRevisionReason describe the detailed reason for the most recent deployment |
|
| nodeStatuses track the deployment values and errors across individual nodes |
|
| NodeStatus provides information about the current state of a particular node managed by this operator. |
|
| observedGeneration is the last generation change you’ve dealt with |
|
| readyReplicas indicates how many replicas are ready and at the desired state |
|
| version is the level this availability applies to |

| 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 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. |
