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of all mappings between tasks we know about and containers docker runs It contains a mutex that can be used to ensure out-of-date state cannot be accessed before an update comes and to ensure multiple goroutines can safely work with it.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 aquire the read lock, but not all aquire 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 

func (state *DockerTaskEngineState) AddContainer(container *api.DockerContainer, task *api.Task)

AddContainer adds a container to the state. If the container has been added with only a name and no docker-id, this updates the state to include the docker id

func (state *DockerTaskEngineState) AddENIAttachment(eniAttachment *api.ENIAttachment)

AddENIAttachment adds the eni into the state

func (*DockerTaskEngineState) AddImageState added in v1.13.0 

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

AddImageState adds an image.ImageState to be stored

func (*DockerTaskEngineState) AddTask added in v1.1.0 

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

AddTask adds a new task to the state

func (*DockerTaskEngineState) AllENIAttachments added in v1.14.5 

func (state *DockerTaskEngineState) AllENIAttachments() []*api.ENIAttachment

AllENIAttachments returns all the enis managed by ecs on the instance

func (*DockerTaskEngineState) AllImageStates added in v1.13.0 

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

AllImageStates returns all of the image.ImageStates

func (*DockerTaskEngineState) AllTasks 

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

AllTasks returns all of the tasks

func (*DockerTaskEngineState) ContainerByID added in v1.14.1 

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 added in v1.14.5 

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

ENIByMac returns the eni object that match the give mac address

func (*DockerTaskEngineState) GetAllContainerIDs added in v1.14.2 

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

GetAllContainerIDs returns all of the Container Ids

func (*DockerTaskEngineState) MarshalJSON 

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

func (*DockerTaskEngineState) RemoveENIAttachment added in v1.14.5 

func (state *DockerTaskEngineState) RemoveENIAttachment(mac string)

RemoveENIAttachment removes the eni from state and stop managing

func (*DockerTaskEngineState) RemoveImageState added in v1.13.0 

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 added in v1.14.4 

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 added in v1.14.1 

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

TaskByID retrieves the task of a given docker container id

func (*DockerTaskEngineState) TaskByShortID added in v1.14.2 

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
