## Was ist ein Container?

Container (hauptsächlich Linux-Container) sind eine sehr **leichtgewichtige** Möglichkeit, Anwendungen einschließlich aller ihrer Abhängigkeiten und erforderlichen Dateien zu verpacken und sie gleichzeitig von anderen Containern (anderen Anwendungen oder Komponenten) im selben System isoliert zu halten.

// ContainerReasonStatusUnknown indicates a container the status of the container cannot be determined.
const ContainerReasonStatusUnknown string = "ContainerStatusUnknown"

// Container provides the runtime information for a container, such as ID, hash,
// state of the container.
type Container struct {
	// The ID of the container, used by the container runtime to identify
	// a container.
	ID ContainerID

func (m *kubeGenericRuntimeManager) generateLinuxContainerResources(pod *v1.Pod, container *v1.Container, enforceMemoryQoS bool) *runtimeapi.LinuxContainerResources {
	// set linux container resources
	var cpuRequest *resource.Quantity
	if _, cpuRequestExists := container.Resources.Requests[v1.ResourceCPU]; cpuRequestExists {
		cpuRequest = container.Resources.Requests.Cpu()
	}

A container image is comparable to the **program** file and contents, e.g. `python` and some file `main.py`.
