Types ¶
type ClientConnectionConfiguration ¶
type ClientConnectionConfiguration struct {
// kubeConfigFile is the path to a kubeconfig file.
KubeConfigFile string
// acceptContentTypes defines the Accept header sent by clients when connecting to a server, overriding the
// default value of 'application/json'. This field will control all connections to the server used by a particular
// client.
AcceptContentTypes string
// contentType is the content type used when sending data to the server from this client.
ContentType string
// qps controls the number of queries per second allowed for this connection.
QPS float32
// burst allows extra queries to accumulate when a client is exceeding its rate.
Burst int
}
ClientConnectionConfiguration contains details for constructing a client.
type LeaderElectionConfiguration ¶
type LeaderElectionConfiguration struct {
// leaderElect enables a leader election client to gain leadership
// before executing the main loop. Enable this when running replicated
// components for high availability.
LeaderElect bool
// leaseDuration is the duration that non-leader candidates will wait
// after observing a leadership renewal until attempting to acquire
// leadership of a led but unrenewed leader slot. This is effectively the
// maximum duration that a leader can be stopped before it is replaced
// by another candidate. This is only applicable if leader election is
// enabled.
LeaseDuration metav1.Duration
// renewDeadline is the interval between attempts by the acting master to
// renew a leadership slot before it stops leading. This must be less
// than or equal to the lease duration. This is only applicable if leader
// election is enabled.
RenewDeadline metav1.Duration
// retryPeriod is the duration the clients should wait between attempting
// acquisition and renewal of a leadership. This is only applicable if
// leader election is enabled.
RetryPeriod metav1.Duration
// resourceLock indicates the resource object type that will be used to lock
// during leader election cycles.
ResourceLock string
}
LeaderElectionConfiguration defines the configuration of leader election clients for components that can run with leader election enabled.
type MachineControllerConfiguration ¶
type MachineControllerConfiguration struct {
metav1.TypeMeta
// namespace in seed cluster in which controller would look for the resources.
Namespace string
// port is the port that the controller-manager's http service runs on.
Port int32
// address is the IP address to serve on (set to 0.0.0.0 for all interfaces).
Address string
// CloudProvider is the provider for cloud services.
CloudProvider string
// ConcurrentNodeSyncs is the number of node objects that are
// allowed to sync concurrently. Larger number = more responsive nodes,
// but more CPU (and network) load.
ConcurrentNodeSyncs int32
// enableProfiling enables profiling via web interface host:port/debug/pprof/
EnableProfiling bool
// enableContentionProfiling enables lock contention profiling, if enableProfiling is true.
EnableContentionProfiling bool
// contentType is contentType of requests sent to apiserver.
ContentType string
// kubeAPIQPS is the QPS to use while talking with kubernetes apiserver.
KubeAPIQPS float32
// kubeAPIBurst is the burst to use while talking with kubernetes apiserver.
KubeAPIBurst int32
// leaderElection defines the configuration of leader election client.
LeaderElection mcmoptions.LeaderElectionConfiguration
// How long to wait between starting controller managers
ControllerStartInterval metav1.Duration
// minResyncPeriod is the resync period in reflectors; will be random between
// minResyncPeriod and 2*minResyncPeriod.
MinResyncPeriod metav1.Duration
// SafetyOptions is the set of options to set to ensure safety of controller
SafetyOptions SafetyOptions
//NodeCondition is the string of known NodeConditions. If any of these NodeCondition is set for a timeout period, the machine will be declared failed and will replaced.
NodeConditions string
//BootstrapTokenAuthExtraGroups is a comma-separated string of groups to set bootstrap token's "auth-extra-groups" field to.
BootstrapTokenAuthExtraGroups string
}
MachineControllerConfiguration contains machine configurations +k8s:deepcopy-gen:interfaces=k8s.io/apimachinery/pkg/runtime.Object
type PortRangeVar ¶
type PortRangeVar struct {
Val *string
}
PortRangeVar is used to store the range of ports
func (PortRangeVar) Set ¶
func (v PortRangeVar) Set(s string) error
Set is used to set the PortRangeVar
func (PortRangeVar) String ¶
func (v PortRangeVar) String() string
String is used to get PortRangeVar in string format
func (PortRangeVar) Type ¶
func (v PortRangeVar) Type() string
Type is used to determine the type of PortRangeVar
type SafetyOptions ¶
type SafetyOptions struct {
// Timeout (in duration) used while creation of
// a machine before it is declared as failed
MachineCreationTimeout metav1.Duration
// Timeout (in duration) used while health-check of
// a machine before it is declared as failed
MachineHealthTimeout metav1.Duration
// Timeout (in duration) used while draining of machine before deletion,
// beyond which it forcefully deletes machine
MachineDrainTimeout metav1.Duration
// Maximum number of times evicts would be attempted on a pod for it is forcibly deleted
// during draining of a machine.
MaxEvictRetries int32
// Timeout (in duration) used while waiting for PV to detach
PvDetachTimeout metav1.Duration
// Timeout (in duration) used while waiting for PV to reattach on new node
PvReattachTimeout metav1.Duration
// Timeout (in duration) for which the APIServer can be down before
// declare the machine controller frozen by safety controller
MachineSafetyAPIServerStatusCheckTimeout metav1.Duration
// Period (in durartion) used to poll for orphan VMs
// by safety controller
MachineSafetyOrphanVMsPeriod metav1.Duration
// Period (in duration) used to poll for APIServer's health
// by safety controller
MachineSafetyAPIServerStatusCheckPeriod metav1.Duration
// APIserverInactiveStartTime to keep track of the
// start time of when the APIServers were not reachable
APIserverInactiveStartTime time.Time
// MachineControllerFrozen indicates if the machine controller
// is frozen due to Unreachable APIServers
MachineControllerFrozen bool
}
SafetyOptions are used to configure the upper-limit and lower-limit while configuring freezing of machineSet objects
