Types

type DockerTaskEngineState

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

DockerTaskEngineState keeps track of all mappings between tasks we know about and containers docker runs It contains a mutex that can be used to ensure out-of-date state cannot be accessed before an update comes and to ensure multiple goroutines can safely work with it.

The methods on it will acquire the read lock, but not all acquire the write lock (sometimes it is up to the caller). This is because the write lock for containers should encapsulate the creation of the resource as well as adding, and creating the resource (docker container) is outside the scope of this package. This isn't ideal usage and I'm open to this being reworked/improved.

Some information is duplicated in the interest of having efficient lookups

func (*DockerTaskEngineState) AddContainer

AddImageState adds an image.ImageState to be stored

func (*DockerTaskEngineState) AddTask

func (state *DockerTaskEngineState) AddTask(task *api.Task)

AddTask adds a new task to the state

func (*DockerTaskEngineState) AddTaskIPAddress

func (state *DockerTaskEngineState) AddTaskIPAddress(addr string, taskARN string)

AddTaskIPAddress adds ip adddress for a task arn into the state

func (*DockerTaskEngineState) AllImageStates

func (state *DockerTaskEngineState) AllImageStates() []*image.ImageState

AllImageStates returns all of the image.ImageStates

func (*DockerTaskEngineState) AllTasks

func (state *DockerTaskEngineState) AllTasks() []*api.Task

func (*DockerTaskEngineState) ContainerByID

func (state *DockerTaskEngineState) ContainerByID(id string) (*api.DockerContainer, bool)

ContainerByID returns an api.DockerContainer for a given container ID

func (*DockerTaskEngineState) ContainerMapByArn

func (state *DockerTaskEngineState) ContainerMapByArn(arn string) (map[string]*api.DockerContainer, bool)

ContainerMapByArn returns a map of containers belonging to a particular task ARN

func (*DockerTaskEngineState) ENIByMac

func (state *DockerTaskEngineState) ENIByMac(mac string) (*api.ENIAttachment, bool)

ENIByMac returns the eni object that match the give mac address

func (*DockerTaskEngineState) GetAllContainerIDs

func (state *DockerTaskEngineState) GetAllContainerIDs() []string

GetAllContainerIDs returns all of the Container Ids

func (*DockerTaskEngineState) GetTaskByIPAddress

func (state *DockerTaskEngineState) GetTaskByIPAddress(addr string) (string, bool)

GetTaskByIPAddress gets the task arn for an IP address

func (*DockerTaskEngineState) MarshalJSON

func (state *DockerTaskEngineState) MarshalJSON() ([]byte, error)

func (*DockerTaskEngineState) RemoveENIAttachment

func (state *DockerTaskEngineState) RemoveENIAttachment(mac string)

RemoveENIAttachment removes the eni from state and stop managing

func (*DockerTaskEngineState) RemoveImageState

func (state *DockerTaskEngineState) RemoveImageState(imageState *image.ImageState)

RemoveImageState removes an image.ImageState

func (*DockerTaskEngineState) RemoveTask

func (state *DockerTaskEngineState) RemoveTask(task *api.Task)

RemoveTask removes a task from this state. It removes all containers and other associated metadata. It does acquire the write lock.

func (*DockerTaskEngineState) Reset

func (state *DockerTaskEngineState) Reset()

Reset resets all the states

func (*DockerTaskEngineState) TaskByArn

func (state *DockerTaskEngineState) TaskByArn(arn string) (*api.Task, bool)

TaskByArn returns a task for a given ARN

func (*DockerTaskEngineState) TaskByID

func (state *DockerTaskEngineState) TaskByID(cid string) (*api.Task, bool)

TaskByID retrieves the task of a given docker container id

func (*DockerTaskEngineState) TaskByShortID

func (state *DockerTaskEngineState) TaskByShortID(cid string) ([]*api.Task, bool)

TaskByShortID retrieves the task of a given docker short container id

func (*DockerTaskEngineState) UnmarshalJSON

func (state *DockerTaskEngineState) UnmarshalJSON(data []byte) error
