	// DesiredStatusUnsafe represents the state where the container should go. Generally,
	// the desired status is informed by the ECS backend as a result of either
	// API calls made to ECS or decisions made by the ECS service scheduler,

	// container in the task exits. The DesiredStatus is almost always either
	// ContainerRunning or ContainerStopped.
	// NOTE: Do not access DesiredStatusUnsafe directly.  Instead, use `GetDesiredStatus`
	// and `SetDesiredStatus`.
	// TODO DesiredStatusUnsafe should probably be private with appropriately written

	TransitionDependencySet TransitionDependencySet `json:"TransitionDependencySet"`

	// SteadyStateDependencies is a list of containers that must be in "steady state" before
	// this one is created
	// Note: Current logic requires that the containers specified here are run

	SteadyStateDependencies []string `json:"RunDependencies"`

	// Type specifies the container type. Except the 'Normal' type, all other types

}

Container is the internal representation of a container in the ECS agent

func NewContainerWithSteadyState added in v1.14.5

NewContainerWithSteadyState creates a new Container object with the specified steady state. Containers that need the non default steady state set will use this method instead of setting it directly

func (*Container) DesiredTerminal 

func (c *Container) DesiredTerminal() bool

DesiredTerminal returns true if the container's desired status is STOPPED

func (*Container) GetDesiredStatus added in v1.12.2

For example: a. if the steady state of the container is defined as `ContainerRunning`, the progression is: Container: None -> Pulled -> Created -> Running* -> Stopped -> Zombie

b. if the steady state of the container is defined as `ContainerResourcesProvisioned`, the progression is: Container: None -> Pulled -> Created -> Running -> Provisioned* -> Stopped -> Zombie

c. if the steady state of the container is defined as `ContainerCreated`, the progression is: Container: None -> Pulled -> Created* -> Stopped -> Zombie

We support both formats in the hopes that one day everything will be fully typed Note: the `json:",string"` tag DOES NOT apply here; it DOES NOT work with struct types, only ints/floats/etc. We're basically doing that though We also intentionally fail if there are any keys we were unable to unmarshal into our struct

	// ContainerResourcesProvisioned represents a container that has completed provisioning all of its
	// resources. Non-internal containers (containers present in the task definition) transition to
	// this state without doing any additional work. However, containers that are added to a task
	// by the ECS Agent would possibly need to perform additional actions before they can be
	// considered "ready" and contribute to the progress of a task. For example, the "pause" container
	// would be provisioned by invoking CNI plugins
	ContainerResourcesProvisioned
