Overview

Package containerizer provides the implementations to store data about Containers and ContainerEngines. Subpackages implement Containerizers that discover Containers from certain container engines.

Nota bene: the lxkns model defines only the Container and ContainerEngine interfaces instead of implementations in order to break import cycles that otherwise would invariably occur.

Types

type Containerizer

type Containerizer interface {
	// Discover user-level "alive" containers.
	//
	// Please note that depending on the particular containerizer implementation
	// the context might be used or not used at all.
	Containers(ctx context.Context, procs model.ProcessTable, pidmap model.PIDMapper) []*model.Container
	// Close and release all resources allocated by this Containerizer.
	Close()
}

Containerizer discovers containers and relates them to processes (and thus also to Linux-kernel namespaces). A Containerizer can optionally be passed to a namespace discovery via the discovery options; the containerizer then will be called in order to discover any "alive" containers.
