flytekit.extend.SerializationSettings#

class flytekit.extend.SerializationSettings(image_config, project=None, domain=None, version=None, env=None, git_repo=None, python_interpreter='/opt/venv/bin/python3', flytekit_virtualenv_root=None, fast_serialization_settings=None, source_root=None)[source]#

These settings are provided while serializing a workflow and task, before registration. This is required to get runtime information at serialization time, as well as some defaults.

Parameters
Return type

None

project#

The project (if any) with which to register entities under.

Type

str

domain#

The domain (if any) with which to register entities under.

Type

str

version#

The version (if any) with which to register entities under.

Type

str

image_config#

The image config used to define task container images.

Type

ImageConfig

env#

Environment variables injected into task container definitions.

Type

Optional[Dict[str, str]]

flytekit_virtualenv_root#

During out of container serialize the absolute path of the flytekit virtualenv at serialization time won’t match the in-container value at execution time. This optional value is used to provide the in-container virtualenv path

Type

Optional[str]

python_interpreter#

The python executable to use. This is used for spark tasks in out of container execution.

Type

Optional[str]

entrypoint_settings#

Information about the command, path and version of the entrypoint program.

Type

Optional[EntrypointSettings]

fast_serialization_settings#

If the code is being serialized so that it can be fast registered (and thus omit building a Docker image) this object contains additional parameters for serialization.

Type

Optional[FastSerializationSettings]

source_root#

The root directory of the source code.

Type

Optional[str]

Parameters
Return type

None

Methods

__init__(image_config[, project, domain, ...])

default_entrypoint_settings(interpreter_path)

Assumes the entrypoint is installed in a virtual-environment where the interpreter is

for_image(image, version[, project, domain, ...])

from_dict(kvs, *[, infer_missing])

from_json(s, *[, parse_float, parse_int, ...])

from_transport(s)

new_builder()

Creates a SerializationSettings.Builder that copies the existing serialization settings parameters and allows for customization.

schema(*[, infer_missing, only, exclude, ...])

should_fast_serialize()

Whether or not the serialization settings specify that entities should be serialized for fast registration.

to_dict([encode_json])

to_json(*[, skipkeys, ensure_ascii, ...])

venv_root_from_interpreter(interpreter_path)

Computes the path of the virtual environment root, based on the passed in python interpreter path for example /opt/venv/bin/python3 -> /opt/venv

with_serialized_context()

Use this method to create a new SerializationSettings that has an environment variable set with the SerializedContext This is useful in transporting SerializedContext to serialized and registered tasks.
