MachineDeploymentSpec defines the desired state of MachineDeployment.

Fields

cluster_name: String

clusterName is the name of the Cluster this object belongs to.

min_ready_seconds: Option<i32>

minReadySeconds is the minimum number of seconds for which a Node for a newly created machine should be ready before considering the replica available. Defaults to 0 (machine will be considered available as soon as the Node is ready)

paused: Option<bool>

Indicates that the deployment is paused.

progress_deadline_seconds: Option<i32>

The maximum time in seconds for a deployment to make progress before it is considered to be failed. The deployment controller will continue to process failed deployments and a condition with a ProgressDeadlineExceeded reason will be surfaced in the deployment status. Note that progress will not be estimated during the time a deployment is paused. Defaults to 600s.

Deprecated: This field is deprecated and is going to be removed in the next apiVersion. Please see https://github.com/kubernetes-sigs/cluster-api/issues/11470 for more details.

replicas: Option<i32>

Number of desired machines. This is a pointer to distinguish between explicit zero and not specified.

Defaults to:

• if the Kubernetes autoscaler min size and max size annotations are set:
  • if it’s a new MachineDeployment, use min size
  • if the replicas field of the old MachineDeployment is < min size, use min size
  • if the replicas field of the old MachineDeployment is > max size, use max size
  • if the replicas field of the old MachineDeployment is in the (min size, max size) range, keep the value from the oldMD
• otherwise use 1 Note: Defaulting will be run whenever the replicas field is not set:
• A new MachineDeployment is created with replicas not set.
• On an existing MachineDeployment the replicas field was first set and is now unset. Those cases are especially relevant for the following Kubernetes autoscaler use cases:
• A new MachineDeployment is created and replicas should be managed by the autoscaler
• An existing MachineDeployment which initially wasn’t controlled by the autoscaler should be later controlled by the autoscaler

revision_history_limit: Option<i32>

The number of old MachineSets to retain to allow rollback. This is a pointer to distinguish between explicit zero and not specified. Defaults to 1.

Deprecated: This field is deprecated and is going to be removed in the next apiVersion. Please see https://github.com/kubernetes-sigs/cluster-api/issues/10479 for more details.

rollout_after: Option<String>

rolloutAfter is a field to indicate a rollout should be performed after the specified time even if no changes have been made to the MachineDeployment. Example: In the YAML the time can be specified in the RFC3339 format. To specify the rolloutAfter target as March 9, 2023, at 9 am UTC use “2023-03-09T09:00:00Z”.

selector: MachineDeploymentSelector

Label selector for machines. Existing MachineSets whose machines are selected by this will be the ones affected by this deployment. It must match the machine template’s labels.

strategy: Option<MachineDeploymentStrategy>

The deployment strategy to use to replace existing machines with new ones.

template: MachineDeploymentTemplate

template describes the machines that will be created.

Trait Implementations

impl Clone for MachineDeploymentSpec

fn clone(&self) -> MachineDeploymentSpec

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MachineDeploymentSpec

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for MachineDeploymentSpec

fn default() -> MachineDeploymentSpec

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for MachineDeploymentSpec

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for MachineDeploymentSpec

fn schema_name() -> String

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn is_referenceable() -> bool

Whether JSON Schemas generated for this type should be re-used where possible using the $ref keyword.

impl PartialEq for MachineDeploymentSpec

fn eq(&self, other: &MachineDeploymentSpec) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for MachineDeploymentSpec

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
