Types

type CRIOFeeder

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

CRIOFeeder wraps the libpod.Runtime and implementes the Feeder interface.

func NewCRIOFeeder

func NewCRIOFeeder() (*CRIOFeeder, error)

NewCRIOFeeder returns a pointer to an initialized CRIOFeeder.

func (*CRIOFeeder) Images

func (f *CRIOFeeder) Images() ([]string, error)

Images returns an array of images present in containers/storage.

func (*CRIOFeeder) LoadImage

func (f *CRIOFeeder) LoadImage(path string) (string, error)

LoadImage loads the specified image into containers/storage and returns the image name.

func (*CRIOFeeder) TagImage

func (f *CRIOFeeder) TagImage(image string, tags []string) error

TagImage tags the specified image with the supplied tags.

type DockerFeeder

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

func NewDockerFeeder

func NewDockerFeeder() (*DockerFeeder, error)

Returns a new Feeder instance. Takes care of initializing the connection with the Docker daemon.

func (*DockerFeeder) Images

func (f *DockerFeeder) Images() ([]string, error)

Images returns images available on the docker host in the form "<repo>:<tag>".

func (*DockerFeeder) LoadImage

func (f *DockerFeeder) LoadImage(pathToImage string) (string, error)

LoadImage loads the specified image into docker. Returns the image name loaded into the docker daemon.

func (*DockerFeeder) TagImage

func (f *DockerFeeder) TagImage(image string, tags []string) error

TagImage tags the specified docker image with the supplied tags.

type FailedImportError

type FailedImportError struct {
	Image string
	Error error
}

type Feeder

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

Feeder includes a concrete object implementing the FeederIface and FeederConfig

func NewFeeder

func NewFeeder() (*Feeder, error)

NewFeeder returns a new Container Feeder based on the specified type in the container-feeder.json config (default: DockerFeeder)

type FeederConfig

type FeederConfig struct {
	Target    string   `json:"feeder-target,omitempty"`
	Whitelist []string `json:"whitelist,omitempty"`
}

special type to load the container-feeder.json config

type FeederIface

type FeederIface interface {
	Images() ([]string, error)
	LoadImage(string) (string, error)
	TagImage(string, []string) error
}

FeederIface is a generalized interface that Container Feeders must implement

type FeederLoadResponse

type FeederLoadResponse struct {
	SuccessfulImports []string
	FailedImports     []FailedImportError
}

func Import

func Import(path string) (FeederLoadResponse, error)

Imports all the RPMs images stored inside of `path` into the local docker daemon

type ImageType

type ImageType struct {
	Name string   `json:"name"`
	Tags []string `json:"tags"`
	File string   `json:"file"`
}

ImageType struct to handle JSON schema

type MetadataType

type MetadataType struct {
	Image ImageType
}

Image metadata type JSON schema:

{
  "image": {
    "name": "",
    "tags": [ ],
    "file": ""
  }
}

For example:

{
  "image": {
    "name": "opensuse/salt-api",
    "tags": [ "13", "13.0.1", "latest" ],
    "file": "salt-api-2017.03-docker-images.x86_64.tar.xz"
  }
}
