func CAPIObjects added in v0.9.0 

func CAPIObjects(ctx context.Context, log logr.Logger, clusterSpec *cluster.Spec, kubeClient kubernetes.Client) (controlPlaneSpec, workersSpec []byte, err error)

CAPIObjects generates the control plane and worker nodes objects for snow provider from clusterSpec.

func ControlPlaneObjects 

func ControlPlaneObjects(ctx context.Context, log logr.Logger, clusterSpec *cluster.Spec, kubeClient kubernetes.Client) ([]kubernetes.Object, error)

func CredentialsSecretName(clusterSpec *cluster.Spec) string

func EksaCredentialsSecret added in v0.12.0 

func EksaCredentialsSecret(datacenter *v1alpha1.SnowDatacenterConfig, credsB64, certsB64 []byte) *v1.Secret

func EtcdadmCluster added in v0.14.0 

func EtcdadmCluster(log logr.Logger, clusterSpec *cluster.Spec, snowMachineTemplate *snowv1.AWSSnowMachineTemplate) *etcdv1.EtcdadmCluster

EtcdadmCluster builds an etcdadmCluster based on an eks-a cluster spec and snowMachineTemplate.

func KubeadmControlPlane 

func KubeadmControlPlane(log logr.Logger, clusterSpec *cluster.Spec, snowMachineTemplate *snowv1.AWSSnowMachineTemplate) (*controlplanev1.KubeadmControlPlane, error)

KubeadmControlPlane generates the kubeadmControlPlane object for snow provider from clusterSpec and snowMachineTemplate.

func MachineTemplate added in v0.14.0 

func MachineTemplate(name string, machineConfig *v1alpha1.SnowMachineConfig, capasPools CAPASIPPools) *snowv1.AWSSnowMachineTemplate

func MachineTemplateDeepDerivative added in v0.12.0 

func MachineTemplateDeepDerivative(new, old *snowv1.AWSSnowMachineTemplate) bool

MachineTemplateDeepDerivative compares two awssnowmachinetemplates to determine if their spec fields are equal. DeepDerivative is used so that unset fields in new object are not compared. Although DeepDerivative treats new subset slice equal to the original slice. i.e. DeepDerivative([]int{1}, []int{1, 2}) returns true. Custom logic is added to justify this usecase since removing a device from the devices list shall trigger machine rollout and recreate or the snow cluster goes into a state where the machines on the removed device can’t be deleted.
