Functions

func LaunchRemoteEnforcer

func LaunchRemoteEnforcer(service packetprocessor.PacketProcessor, zapConfig zap.Config) error

LaunchRemoteEnforcer launches a remote enforcer instance.

Types

type DebugInfo

type DebugInfo interface {
	// EnableReceivedPacketTracing will enable tracing of packets received by the datapath for a particular PU. Setting Disabled as tracing direction will stop tracing for the contextID
	EnableDatapathPacketTracing(contextID string, direction packettracing.TracingDirection, interval time.Duration, putype common.PUType) error
	// EnablePacketTracing enable iptables -j trace for the particular pu and is much wider packet stream.
	EnableIPTablesPacketTracing(ctx context.Context, contextID string, interval time.Duration, putype common.PUType) error
}

type TriremeController

type TriremeController interface {
	// Run initializes and runs the controller.
	Run(ctx context.Context) error

	// CleanUp cleans all the supervisors and ACLs for a clean exit
	CleanUp() error

	// Enforce asks the controller to enforce policy on a processing unit
	Enforce(ctx context.Context, puID string, policy *policy.PUPolicy, runtime *policy.PURuntime) (err error)

	// UnEnforce asks the controller to ub-enforce policy on a processing unit
	UnEnforce(ctx context.Context, puID string, policy *policy.PUPolicy, runtime *policy.PURuntime) (err error)

	// UpdatePolicy updates the policy of the isolator for a container.
	UpdatePolicy(ctx context.Context, puID string, policy *policy.PUPolicy, runtime *policy.PURuntime) error

	// UpdateSecrets updates the secrets of running enforcers managed by trireme. Remote enforcers will get the secret updates with the next policy push
