This gets set before the machine config operator validates the new machine config against the current machine config.

Type

object

Required
  • desired

Property Type Description

desired

string

desired is the name of the machine config that the the node should be upgraded to. This value is set when the machine config pool generates a new version of its rendered configuration. When this value is changed, the machine config daemon starts the node upgrade process. This value gets set in the machine config node spec once the machine config has been targeted for upgrade and before it is validated. Must be a lowercase RFC-1123 hostname (https://tools.ietf.org/html/rfc1123) It may consist of only alphanumeric characters, hyphens (-) and periods (.) and must be at most 253 characters in length.

.status

Description

status describes the last observed state of this machine config node.

Type

object

Required
  • configVersion

Property Type Description

conditions

array

conditions represent the observations of a machine config node’s current state.

conditions[]

object

Condition contains details for one aspect of the current state of this API Resource. --- This struct is intended for direct use as an array at the field path .status.conditions. For example, type FooStatus struct{ // Represents the observations of a foo’s current state. // Known .status.conditions.type are: "Available", "Progressing", and "Degraded" // +patchMergeKey=type // +patchStrategy=merge // +listType=map // +listMapKey=type Conditions []metav1.Condition json:"conditions,omitempty" patchStrategy:"merge" patchMergeKey:"type" protobuf:"bytes,1,rep,name=conditions" // other fields }

configVersion

object

configVersion describes the current and desired machine config for this node. The current version represents the current machine config for the node and is updated after a successful update. The desired version represents the machine config the node will attempt to update to. This desired machine config has been compared to the current machine config and has been validated by the machine config operator as one that is valid and that exists.

observedGeneration

integer

observedGeneration represents the generation observed by the controller. This field is updated when the controller observes a change to the desiredConfig in the configVersion of the machine config node spec.

.status.conditions

Description

conditions represent the observations of a machine config node’s current state.

Type

array

.status.conditions[]

Description

Condition contains details for one aspect of the current state of this API Resource. --- This struct is intended for direct use as an array at the field path .status.conditions. For example, type FooStatus struct{ // Represents the observations of a foo’s current state. // Known .status.conditions.type are: "Available", "Progressing", and "Degraded" // +patchMergeKey=type // +patchStrategy=merge // +listType=map // +listMapKey=type Conditions []metav1.Condition json:"conditions,omitempty" patchStrategy:"merge" patchMergeKey:"type" protobuf:"bytes,1,rep,name=conditions" // other fields }

Type

object

Required
  • lastTransitionTime

  • message

  • reason

  • 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

message is a human readable message indicating details about the transition. This may be an empty string.

observedGeneration

integer

observedGeneration represents the .metadata.generation that the condition was set based upon. For instance, if .metadata.generation is currently 12, but the .status.conditions[x].observedGeneration is 9, the condition is out of date with respect to the current state of the instance.

reason

string

reason contains a programmatic identifier indicating the reason for the condition’s last transition. Producers of specific condition types may define expected values and meanings for this field, and whether the values are considered a guaranteed API. The value should be a CamelCase string. This field may not be empty.

status

string

status of the condition, one of True, False, Unknown.

type

string

type of condition in CamelCase or in foo.example.com/CamelCase. --- Many .condition.type values are consistent across resources like Available, but because arbitrary conditions can be useful (see .node.status.conditions), the ability to deconflict is important. The regex it matches is (dns1123SubdomainFmt/)?(qualifiedNameFmt)

.status.configVersion

Description

configVersion describes the current and desired machine config for this node. The current version represents the current machine config for the node and is updated after a successful update. The desired version represents the machine config the node will attempt to update to. This desired machine config has been compared to the current machine config and has been validated by the machine config operator as one that is valid and that exists.

Type

object

Required
  • desired

Property Type Description

current

string

current is the name of the machine config currently in use on the node. This value is updated once the machine config daemon has completed the update of the configuration for the node. This value should match the desired version unless an upgrade is in progress. Must be a lowercase RFC-1123 hostname (https://tools.ietf.org/html/rfc1123) It may consist of only alphanumeric characters, hyphens (-) and periods (.) and must be at most 253 characters in length.

desired

string

desired is the MachineConfig the node wants to upgrade to. This value gets set in the machine config node status once the machine config has been validated against the current machine config. Must be a lowercase RFC-1123 hostname (https://tools.ietf.org/html/rfc1123) It may consist of only alphanumeric characters, hyphens (-) and periods (.) and must be at most 253 characters in length.

Table 3. 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. The error returned from the server will contain all unknown and duplicate fields encountered.
