Functions ¶

func DetectCRISocket ¶

func DetectCRISocket() (string, error)

DetectCRISocket uses a list of known CRI sockets to detect one. If more than one or none is discovered, an error is returned.

Types ¶

type CRIRuntime ¶

type CRIRuntime struct {
	// contains filtered or unexported fields
}

CRIRuntime is a struct that interfaces with the CRI

func (*CRIRuntime) ImageExists ¶

func (runtime *CRIRuntime) ImageExists(image string) (bool, error)

ImageExists checks to see if the image exists on the system

func (*CRIRuntime) IsDocker ¶

func (runtime *CRIRuntime) IsDocker() bool

IsDocker returns true if the runtime is docker

func (*CRIRuntime) IsRunning ¶

func (runtime *CRIRuntime) IsRunning() error

IsRunning checks if runtime is running

func (*CRIRuntime) ListKubeContainers ¶

func (runtime *CRIRuntime) ListKubeContainers() ([]string, error)

ListKubeContainers lists running k8s CRI pods

func (*CRIRuntime) PullImage ¶

func (runtime *CRIRuntime) PullImage(image string) error

PullImage pulls the image

func (*CRIRuntime) RemoveContainers ¶

func (runtime *CRIRuntime) RemoveContainers(containers []string) error

RemoveContainers removes running k8s pods

type ContainerRuntime ¶

type ContainerRuntime interface {
	IsDocker() bool
	IsRunning() error
	ListKubeContainers() ([]string, error)
	RemoveContainers(containers []string) error
	PullImage(image string) error
	ImageExists(image string) (bool, error)
}

ContainerRuntime is an interface for working with container runtimes

func NewContainerRuntime ¶

func NewContainerRuntime(execer utilsexec.Interface, criSocket string) (ContainerRuntime, error)

NewContainerRuntime sets up and returns a ContainerRuntime struct

type DockerRuntime ¶

type DockerRuntime struct {
	// contains filtered or unexported fields
}

DockerRuntime is a struct that interfaces with the Docker daemon

func (*DockerRuntime) ImageExists ¶

func (runtime *DockerRuntime) ImageExists(image string) (bool, error)

ImageExists checks to see if the image exists on the system

func (*DockerRuntime) IsDocker ¶

func (runtime *DockerRuntime) IsDocker() bool

IsDocker returns true if the runtime is docker

func (*DockerRuntime) IsRunning ¶

func (runtime *DockerRuntime) IsRunning() error
