Functions

func CreateClientOpts 

func CreateClientOpts(ctx context.Context, env Env) ([]func(client *client.Client) error, error)

Adapted from client.FromEnv

Supported environment variables: DOCKER_HOST to set the url to the docker server. DOCKER_API_VERSION to set the version of the API to reach, leave empty for latest. DOCKER_CERT_PATH to load the TLS certificates from. DOCKER_TLS_VERIFY to enable or disable TLS verification, off by default.

func IsExitError 

func IsExitError(err error) bool

func NegotiateAPIVersion added in v0.4.1 

func NegotiateAPIVersion(ctx context.Context) func(client *client.Client) error

func NewFakeDockerResponse 

func NewFakeDockerResponse(contents string) fakeDockerResponse

func ProvideDockerClient added in v0.7.11 

func ProvideDockerClient(ctx context.Context, env Env) (*client.Client, error)

func ProvideDockerVersion added in v0.7.11 

func ProvideDockerVersion(ctx context.Context, client *client.Client) (types.Version, error)

func SupportedVersion added in v0.4.1 

func SupportedVersion(v types.Version) bool

func SupportsBuildkit added in v0.4.1 

func SupportsBuildkit(v types.Version) bool

Sadly, certain versions of docker return an error if the client requests buildkit. We have to infer whether it supports buildkit from version numbers.
