func (*DefaultManager) ResourceStore 

func (m *DefaultManager) ResourceStore() model.ResourceStore

ResourceStore provides access to the store to render configurations

func (*DefaultManager) SendAgentMessage 

func (m *DefaultManager) SendAgentMessage(ctx context.Context, message Message) error

SendAgentMessage sends a message to an agent

func (*DefaultManager) Shutdown 

func (m *DefaultManager) Shutdown(ctx context.Context) error

Shutdown should disconnect all agents and is called before shutdown of the server

func (*DefaultManager) Start 

func (m *DefaultManager) Start(ctx context.Context)

Start starts the manager and concurrently running jobs

func (*DefaultManager) StartCleanupAgents 

func (m *DefaultManager) StartCleanupAgents()

StartCleanupAgents starts a goroutine that will handle agent cleanup. It will stop once the ManagerCtx is closed

func (*DefaultManager) Store 

func (m *DefaultManager) Store() store.Store

Store provides access to the BindPlane Store

func (*DefaultManager) UpsertAgent 

func (m *DefaultManager) UpsertAgent(ctx context.Context, agentID string, updater store.AgentUpdater) (*model.Agent, error)

UpsertAgent adds a new Agent to the Store or updates an existing one

func (*DefaultManager) VerifySecretKey 

func (m *DefaultManager) VerifySecretKey(ctx context.Context, secretKey string) (context.Context, bool)

VerifySecretKey checks to see if the specified secretKey matches configured secretKey. If the BindPlane server does not have a configured secretKey, this returns true. This implementation doesn't use or modify the context, but it is included to match the interface.

type Manager 

type Manager interface {
	// EnableProtocol adds the protocol to the manager
	EnableProtocol(protocol.Protocol)
	// Agent returns the agent with the specified agentID.
	Agent(ctx context.Context, agentID string) (*model.Agent, error)
	// UpsertAgent adds a new Agent to the Store or updates an existing one
