flytekit.image_spec.image_spec.CopyFileDetection

Create a collection of name/value pairs.

Example enumeration:

class Color(Enum): … RED = 1 … BLUE = 2 … GREEN = 3

Access them by:

• attribute access:

Color.RED <Color.RED: 1>

• value lookup:

Color(1) <Color.RED: 1>

• name lookup:

Color[‘RED’] <Color.RED: 1>

Enumerations can be iterated over, and know how many members they have:

len(Color) 3

list(Color) [<Color.RED: 1>, <Color.BLUE: 2>, <Color.GREEN: 3>]

Methods can be added to enumerations, and members can have their own attributes – see the documentation for details.

Methods

exist()

def exist()

Check if the image exists in the registry. Return True if the image exists in the registry, False otherwise. Return None if failed to check if the image exists due to the permission issue or other reasons.

force_push()

def force_push()

Builder that returns a new image spec with force push enabled.

from_env()

def from_env(
    pinned_packages: typing.Optional[typing.List[str]],
    kwargs,
):

Create ImageSpec with the environment’s Python version and packages pinned to the ones in the environment.

image_name()

def image_name()

Full image name with tag.

is_container()

def is_container()

Check if the current container image in the pod is built from current image spec. :return: True if the current container image in the pod is built from current image spec, False otherwise.

with_apt_packages()

def with_apt_packages(
    apt_packages: typing.Union[str, typing.List[str]],
):

Builder that returns a new image spec with an additional list of apt packages that will be executed during the building process.

with_commands()

def with_commands(
    commands: typing.Union[str, typing.List[str]],
):

Builder that returns a new image spec with an additional list of commands that will be executed during the building process.

with_copy()

def with_copy(
    src: typing.Union[str, typing.List[str]],
):

Builder that returns a new image spec with the source files copied to the destination directory.

with_packages()

def with_packages(
    packages: typing.Union[str, typing.List[str]],
):

Builder that returns a new image speck with additional python packages that will be installed during the building process.

Properties

flytekit.image_spec.image_spec.ImageSpecBuilder

Methods

build_image()

def build_image(
    image_spec: flytekit.image_spec.image_spec.ImageSpec,
):

Build the docker image and push it to the registry.

should_build()

def should_build(
    image_spec: flytekit.image_spec.image_spec.ImageSpec,
):

Whether or not the builder should build the ImageSpec.

flytekit.image_spec.image_spec.Version

This class abstracts handling of a project’s versions.

A :class:Version instance is comparison aware and can be compared and sorted using the standard Python interfaces.

v1 = Version(“1.0a5”) v2 = Version(“1.0”) v1 <Version(‘1.0a5’)> v2 <Version(‘1.0’)> v1 < v2 True v1 == v2 False v1 > v2 False v1 >= v2 False v1 <= v2 True

def Version(
    version: str,
):

Initialize a Version object.
