Constants ¶
const AnnotationNameManagement = "kops.kubernetes.io/management"
AnnotationNameManagement is the annotation that indicates that a cluster is under external or non-standard management
const AnnotationValueManagementImported = "imported"
AnnotationValueManagementImported is the annotation value that indicates a cluster was imported, typically as part of an upgrade
const DefaultChannel = "stable"
const DefaultChannelBase = "https://raw.githubusercontent.com/kubernetes/kops/master/channels/"
const RoleLabelName = "kubernetes.io/role"
const RoleMasterLabelValue = "master"
const UpdatePolicyExternal = "external"
UpdatePolicyExternal is a value for ClusterSpec.UpdatePolicy indicating that upgrades are done externally, and we should disable automatic upgrades

Types ¶
type Channel ¶
type Channel struct { unversioned.TypeMeta `json:",inline"` k8sapi.ObjectMeta `json:"metadata,omitempty"` Spec ChannelSpec `json:"spec,omitempty"` }
func LoadChannel ¶
LoadChannel loads a Channel object from the specified VFS location
func (*Channel) FindImage ¶
func (c *Channel) FindImage(provider fi.CloudProviderID) *ChannelImageSpec

func (*Cluster) FillDefaults ¶
FillDefaults populates default values. This is different from PerformAssignments, because these values are changeable, and thus we don't need to store them (i.e. we don't need to 'lock them')
func (*Cluster) PerformAssignments ¶
PerformAssignments populates values that are required and immutable For example, it assigns stable Keys to NodeSets & Masters, and it assigns CIDRs to subnets We also assign KubernetesVersion, because we want it to be explicit
