Types

type Daemon 

type Daemon struct {
	// contains filtered or unexported fields
}

func (*Daemon) AddIdentity added in v1.17.0 

func (d *Daemon) AddIdentity(id *identity.Identity)

func (*Daemon) BandwidthManager added in v1.17.0 

func (d *Daemon) BandwidthManager() datapath.BandwidthManager

BandwidthManager returns a reference to the bandwidth manager implementation.

func (*Daemon) Close 

func (d *Daemon) Close()

Close shuts down a daemon

func (*Daemon) DeleteEndpoint 

func (d *Daemon) DeleteEndpoint(id string) (int, error)

func (*Daemon) DumpIPAM 

func (d *Daemon) DumpIPAM() *models.IPAMStatus

DumpIPAM dumps in the form of a map, the list of reserved IPv4 and IPv6 addresses.

func (*Daemon) EndpointCreated 

func (d *Daemon) EndpointCreated(ep *endpoint.Endpoint)

EndpointCreated is a callback to satisfy EndpointManager.Subscriber, allowing the EndpointManager to be the primary implementer of the core endpoint management functionality while deferring other responsibilities to the daemon.

It is called after Daemon calls into d.endpointManager.AddEndpoint().

func (*Daemon) EndpointDeleted 

func (d *Daemon) EndpointDeleted(ep *endpoint.Endpoint, conf endpoint.DeleteConfig)

EndpointDeleted is a callback to satisfy EndpointManager.Subscriber, which works around the difficulties in initializing various subsystems involved in managing endpoints, such as the EndpointManager, IPAM and the Monitor.

It is called after Daemon calls into d.endpointManager.RemoveEndpoint().

func (*Daemon) EndpointRestored added in v1.16.0 

func (d *Daemon) EndpointRestored(ep *endpoint.Endpoint)

EndpointRestored implements endpointmanager.Subscriber.

func (*Daemon) EndpointUpdate 

func (d *Daemon) EndpointUpdate(id string, cfg *models.EndpointConfigurationSpec) error

EndpointUpdate updates the options of the given endpoint and regenerates the endpoint

func (*Daemon) GetCompilationLock 

func (d *Daemon) GetCompilationLock() datapath.CompilationLock

GetCompilationLock returns the mutex responsible for synchronizing compilation of BPF programs.

func (*Daemon) GetDNSRules 

func (d *Daemon) GetDNSRules(epID uint16) restore.DNSRules

func (*Daemon) GetPolicyRepository 

func (d *Daemon) GetPolicyRepository() policy.PolicyRepository

GetPolicyRepository returns the policy repository of the daemon

func (*Daemon) IPTablesManager added in v1.17.0 

func (d *Daemon) IPTablesManager() datapath.IptablesManager

func (*Daemon) Loader added in v1.17.0 

func (d *Daemon) Loader() datapath.Loader

Loader returns a reference to the loader implementation.

func (*Daemon) Orchestrator added in v1.17.0 

func (d *Daemon) Orchestrator() datapath.Orchestrator

Orchestrator returns a reference to the orchestrator implementation.

func (*Daemon) PolicyAdd 

func (d *Daemon) PolicyAdd(rules policyAPI.Rules, opts *policy.AddOptions) (newRev uint64, err error)

PolicyAdd adds a slice of rules to the policy repository owned by the daemon. Eventual changes in policy rules are propagated to all locally managed endpoints. Returns the policy revision number of the repository after adding the rules into the repository, or an error if the updated policy was not able to be imported.

func (*Daemon) PolicyDelete 

func (d *Daemon) PolicyDelete(labels labels.LabelArray, opts *policy.DeleteOptions) (newRev uint64, err error)

PolicyDelete deletes the policy rules with the provided set of labels from the policy repository of the daemon. Returns the revision number and an error in case it was not possible to delete the policy.

func (*Daemon) QueueEndpointBuild 

func (d *Daemon) QueueEndpointBuild(ctx context.Context, epID uint64) (func(), error)

QueueEndpointBuild waits for a "build permit" for the endpoint identified by 'epID'. This function blocks until the endpoint can start building. The returned function must then be called to release the "build permit" when the most resource intensive parts of the build are done. The returned function is idempotent, so it may be called more than once. Returns a nil function if the caller should NOT start building the endpoint. This may happen due to a build being queued for the endpoint already, or due to the wait for the build permit being canceled. The latter case happens when the endpoint is being deleted. Returns an error if the build permit could not be acquired.

func (*Daemon) RemoveIdentity added in v1.17.0 

func (d *Daemon) RemoveIdentity(id *identity.Identity)

func (*Daemon) RemoveOldAddNewIdentity added in v1.17.0 

func (d *Daemon) RemoveOldAddNewIdentity(old, new *identity.Identity)

func (*Daemon) RemoveRestoredDNSRules 

func (d *Daemon) RemoveRestoredDNSRules(epID uint16)

func (*Daemon) SendNotification 

func (d *Daemon) SendNotification(notification monitorAPI.AgentNotifyMessage) error

SendNotification sends an agent notification to the monitor

func (*Daemon) WaitForEndpointRestore added in v1.15.0 

func (d *Daemon) WaitForEndpointRestore(ctx context.Context)

type DaemonInterface 

type DaemonInterface interface {
	// contains filtered or unexported methods
}

DaemonInterface to help with testing.

type EndpointMapManager 

type EndpointMapManager struct {
	endpointmanager.EndpointManager
}

EndpointMapManager is a wrapper around an endpointmanager as well as the filesystem for removing maps related to endpoints from the filesystem.

func (*EndpointMapManager) RemoveDatapathMapping 

func (e *EndpointMapManager) RemoveDatapathMapping(endpointID uint16) error

RemoveDatapathMapping unlinks the endpointID from the global policy map, preventing packets that arrive on this node from being forwarded to the endpoint that used to exist with the specified ID.

func (*EndpointMapManager) RemoveMapPath 

func (e *EndpointMapManager) RemoveMapPath(path string)

RemoveMapPath removes the specified path from the filesystem.

type PolicyAddEvent 

type PolicyAddEvent struct {
	// contains filtered or unexported fields
}

PolicyAddEvent is a wrapper around the parameters for policyAdd.

func (*PolicyAddEvent) Handle 

func (p *PolicyAddEvent) Handle(res chan interface{})

Handle implements pkg/eventqueue/EventHandler interface.

type PolicyAddResult 

type PolicyAddResult struct {
	// contains filtered or unexported fields
}

PolicyAddResult is a wrapper around the values returned by policyAdd. It contains the new revision of a policy repository after adding a list of rules to it, and any error associated with adding rules to said repository.

type PolicyDeleteEvent 

type PolicyDeleteEvent struct {
	// contains filtered or unexported fields
}

PolicyDeleteEvent is a wrapper around deletion of policy rules with a given set of labels from the policy repository in the daemon.

func (*PolicyDeleteEvent) Handle 

func (p *PolicyDeleteEvent) Handle(res chan interface{})

Handle implements pkg/eventqueue/EventHandler interface.

type PolicyDeleteResult 

type PolicyDeleteResult struct {
	// contains filtered or unexported fields
}

PolicyDeleteResult is a wrapper around the values returned by policyDelete. It contains the new revision of a policy repository after deleting a list of rules to it, and any error associated with adding rules to said repository.

type PolicyReactionEvent 

type PolicyReactionEvent struct {
	// contains filtered or unexported fields
}

PolicyReactionEvent is an event which needs to be serialized after changes to a policy repository for a daemon. This currently consists of endpoint regenerations / policy revision incrementing for a given endpoint.

func (*PolicyReactionEvent) Handle 

func (r *PolicyReactionEvent) Handle(res chan interface{})

Handle implements pkg/eventqueue/EventHandler interface.
