python_awslambda

A self-contained Python function suitable for uploading to AWS Lambda.

See https://www.pantsbuild.org/v2.3/docs/awslambda-python.

Backend: ``

handler​

str
required

Entry point to the AWS Lambda handler.

You can specify a full module like 'path.to.module:handler_func' or use a shorthand to specify a file name, using the same syntax as the sources field, e.g. 'lambda.py:handler_func'.

You must use the file name shorthand for file arguments to work with this target.

runtime​

str
required

The identifier of the AWS Lambda runtime to target (pythonX.Y). See https://docs.aws.amazon.com/lambda/latest/dg/lambda-python.html.

dependencies​

Iterable[str] | None
default: None

Addresses to other targets that this target depends on, e.g. ['helloworld/subdir:lib'].

Alternatively, you may include file names. Pants will find which target owns that file, and create a new target from that which only includes the file in its sources field. For files relative to the current BUILD file, prefix with ./; otherwise, put the full path, e.g. ['./sibling.txt', 'resources/demo.json'].

You may exclude dependencies by prefixing with !, e.g. ['!helloworld/subdir:lib', '!./sibling.txt']. Ignores are intended for false positives with dependency inference; otherwise, simply leave off the dependency from the BUILD file.

description​

str | None
default: None

A human-readable description of the target.

Use ./pants list --documented :: to see all targets with descriptions.

interpreter_constraints​

Iterable[str] | None
default: None

The Python interpreters this code is compatible with.

Each element should be written in pip-style format, e.g. 'CPython==2.7.*' or 'CPython>=3.6,<4'. You can leave off CPython as a shorthand, e.g. '>=2.7' will be expanded to 'CPython>=2.7'.

Specify more than one element to OR the constraints, e.g. ['PyPy==3.7.*', 'CPython==3.7.*'] means either PyPy 3.7 or CPython 3.7.

If the field is not set, it will default to the option [python-setup].interpreter_constraints.

See https://www.pantsbuild.org/v2.3/docs/python-interpreter-compatibility.

output_path​

str | None
default: None

Where the built asset should be located.

If undefined, this will use the path to the BUILD file, followed by the target name. For example, src/python/project:app would be `src.python.project/app.ext.

When running ./pants package, this path will be prefixed by --distdir (e.g. dist/).

Warning: setting this value risks naming collisions with other package targets you may have.

tags​

Iterable[str] | None
default: None

Arbitrary strings to describe a target.

For example, you may tag some test targets with 'integration_test' so that you could run ./pants --tag='integration_test' test :: to only run on targets with that tag.
