Types

type ResourceFields

type ResourceFields struct {
	Control cgroup.Control
	*ResourceFieldsCommon
	Ctx              context.Context
	DockerClient     dockerapi.DockerClient
	NvidiaGPUManager gpu.GPUManager
}

ResourceFields is the list of fields required for creation of task resources obtained from engine

type ResourceFieldsCommon

type ResourceFieldsCommon struct {
	IOUtil             ioutilwrapper.IOUtil
	ASMClientCreator   asmfactory.ClientCreator
	SSMClientCreator   ssmfactory.SSMClientCreator
	CredentialsManager credentials.Manager
	EC2InstanceID      string
}

type TaskResource

type TaskResource interface {
	// SetDesiredStatus sets the desired status of the resource
	SetDesiredStatus(resourcestatus.ResourceStatus)
	// GetDesiredStatus gets the desired status of the resource
	GetDesiredStatus() resourcestatus.ResourceStatus
	// SetKnownStatus sets the desired status of the resource
	SetKnownStatus(resourcestatus.ResourceStatus)
	// GetKnownStatus gets the desired status of the resource
	GetKnownStatus() resourcestatus.ResourceStatus
	// SetCreatedAt sets the timestamp for resource's creation time
	SetCreatedAt(time.Time)
	// GetCreatedAt sets the timestamp for resource's creation time
	GetCreatedAt() time.Time
	// Create performs resource creation
	Create() error
	// Cleanup performs resource cleanup
	Cleanup() error
	// GetName returns the unique name of the resource
	GetName() string
	// DesiredTeminal returns true if remove is in terminal state
	DesiredTerminal() bool
	// KnownCreated returns true if resource state is CREATED
	KnownCreated() bool
	// TerminalStatus returns the last transition state of the resource
	TerminalStatus() resourcestatus.ResourceStatus
	// NextKnownState returns resource's next state
	NextKnownState() resourcestatus.ResourceStatus
	// ApplyTransition calls the function required to move to the specified status
	ApplyTransition(resourcestatus.ResourceStatus) error
	// SteadyState returns the transition state of the resource defined as "ready"
	SteadyState() resourcestatus.ResourceStatus
	// SetAppliedStatus sets the applied status of resource and returns whether
	// the resource is already in a transition
	SetAppliedStatus(status resourcestatus.ResourceStatus) bool
	// GetAppliedStatus gets the applied status of resource
	GetAppliedStatus() resourcestatus.ResourceStatus
	// StatusString returns the string of the resource status
	StatusString(status resourcestatus.ResourceStatus) string
	// GetTerminalReason returns string describing why the resource failed to
	// provision
	GetTerminalReason() string
	// DependOnTaskNetwork shows whether the resource creation needs task network setup beforehand
	DependOnTaskNetwork() bool
	// GetContainerDependencies returns dependent containers for a status
	GetContainerDependencies(resourcestatus.ResourceStatus) []apicontainer.ContainerDependency
	// BuildContainerDependency adds a new dependency container and its satisfied status
	BuildContainerDependency(containerName string, satisfied apicontainerstatus.ContainerStatus,
		dependent resourcestatus.ResourceStatus)
	// Initialize will initialze the resource fields of the resource
	Initialize(res *ResourceFields,
		taskKnownStatus apitaskstatus.TaskStatus, taskDesiredStatus apitaskstatus.TaskStatus)

	json.Marshaler
	json.Unmarshaler
}

TaskResource is a wrapper for task level resource methods we need

type TransitionDependenciesMap

type TransitionDependenciesMap map[resourcestatus.ResourceStatus]TransitionDependencySet

TransitionDependenciesMap is a map of the dependent resource status to other dependencies that must be satisfied.

type TransitionDependencySet

type TransitionDependencySet struct {
	// ContainerDependencies is the set of containers on which a transition is
	// dependent.
	ContainerDependencies []apicontainer.ContainerDependency `json:"ContainerDependencies"`
}

TransitionDependencySet contains dependencies that impact transitions of resources.
