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of all mappings between tasks we know about and containers docker runs It contains a mutex that can be used to ensure out-of-date state cannot be accessed before an update comes and to ensure multiple goroutines can safely work with it.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

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