Functions

func GetLatestDevVersion added in v0.53.1 

func GetLatestDevVersion(url string) (string, error)

GetLatestDevVersion just GETs a known URL which holds the reference to the latest dev version.

Types

type Client added in v0.17.1 

type Client interface {
	PullImages(images []string, retries int) []error
	PushImages(images []TagPair, retries int) []error
	DownloadImages(images []string, version string) (string, error)
	DeleteImages(images []string, retries int) []error
	RunImage(image string, entrypoint string, args ...string) ([]string, error)
}

Client is the interface for interacting with images.

func NewDockerClient added in v0.17.1 

func NewDockerClient() Client

NewDockerClient returns a DockerClient that can interact with the local docker installation.

type Config 

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

Config holds an image's fully qualified name components registry, name, and tag

func (Config) GetFullyQualifiedImageName added in v0.17.1 

func (i Config) GetFullyQualifiedImageName() string

GetFullyQualifiedImageName returns the fully qualified URI to an image (including tag)

type ConformanceImageVersion 

type ConformanceImageVersion string

ConformanceImageVersion represents the version of a conformance image, or "auto" to detect the version

func (*ConformanceImageVersion) Get 

func (c *ConformanceImageVersion) Get(client discovery.ServerVersionInterface, latestURL string) (registry, version string, returnErr error)

Get retrieves the preset version if there is one, queries client if the ConformanceImageVersion is set to `auto`, or finds the latest dev image published. kubernetes.Interface.Discovery() provides ServerVersionInterface. Don't require the entire kubernetes.Interface to simplify the required test mocks

func (*ConformanceImageVersion) Set 

func (c *ConformanceImageVersion) Set(str string) error

Set the ImageVersion to either the string "auto" or a version string. The resulting version string will be forced into semver version with a 'v' prefix. You can set pre-release/metadata but it will fill in the minor/patch values as '0' if missing. E.g. 1+beta would yield v1.0.0+beta

func (*ConformanceImageVersion) String 

func (c *ConformanceImageVersion) String() string

String needed for pflag.Value.

func (*ConformanceImageVersion) Type 

func (c *ConformanceImageVersion) Type() string

Type needed for pflag.Value.

type DockerClient added in v0.17.1 

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

DockerClient is an implementation of Client that uses the local docker installation to interact with images.

func (DockerClient) DeleteImages added in v0.17.1 

func (i DockerClient) DeleteImages(images []string, retries int) []error

DeleteImages deletes the given list of images from the local machine. It will retry for the provided number of retries on failure.

func (DockerClient) DownloadImages added in v0.17.1 

func (i DockerClient) DownloadImages(images []string, version string) (string, error)

DownloadImages exports the list of images to a tar file. The provided version will be included in the resulting file name.

func (DockerClient) PullImages added in v0.17.1 

func (i DockerClient) PullImages(images []string, retries int) []error

PullImages pulls the given list of images, skipping if they are already present on the machine. It will retry for the provided number of retries on failure.

func (DockerClient) PushImages added in v0.17.1 

func (i DockerClient) PushImages(images []TagPair, retries int) []error

PushImages will tag each of the source images as the destination image and push. It will skip the operation if the image source and destination are equal. It will retry for the provided number of retries on failure.
