python_awslambda


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

See https://www.pantsbuild.org/v2.14/docs/awslambda-python.

Backend: pants.backend.awslambda.python


tags

field.type_hint
required

Arbitrary strings to describe a target.

For example, you may tag some test targets with 'integration_test' so that you could run /home/josh/work/scie-pants/dist/scie-pants-linux-x86_64 --tag='integration_test' test :: to only run on targets with that tag.

description

field.type_hint
required

A human-readable description of the target.

Use /home/josh/work/scie-pants/dist/scie-pants-linux-x86_64 list --documented :: to see all targets with descriptions.

output_path

field.type_hint
required

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 /home/josh/work/scie-pants/dist/scie-pants-linux-x86_64 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.

dependencies

field.type_hint
required

Addresses to other targets that this target depends on, e.g. ['helloworld/subdir:lib', 'helloworld/main.py:lib', '3rdparty:reqs#django'].

This augments any dependencies inferred by Pants, such as by analyzing your imports. Use /home/josh/work/scie-pants/dist/scie-pants-linux-x86_64 dependencies or /home/josh/work/scie-pants/dist/scie-pants-linux-x86_64 peek on this target to get the final result.

See https://www.pantsbuild.org/v2.14/docs/targets for more about how addresses are formed, including for generated targets. You can also run /home/josh/work/scie-pants/dist/scie-pants-linux-x86_64 list :: to find all addresses in your project, or /home/josh/work/scie-pants/dist/scie-pants-linux-x86_64 list dir to find all addresses defined in that directory.

If the target is in the same BUILD file, you can leave off the BUILD file path, e.g. :tgt instead of helloworld/subdir:tgt. For generated first-party addresses, use ./ for the file path, e.g. ./main.py:tgt; for all other generated targets, use :tgt#generated_name.

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.

handler

field.type_hint
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.

include_requirements

field.type_hint
default: True

Whether to resolve requirements and include them in the Pex. This is most useful with Lambda Layers to make code uploads smaller when deps are in layers. https://docs.aws.amazon.com/lambda/latest/dg/configuration-layers.html

runtime

field.type_hint
required

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

complete_platforms

field.type_hint
required

The platforms the built PEX should be compatible with.

There must be built wheels available for all of the foreign platforms, rather than sdists.

You can give a list of multiple complete platforms to create a multiplatform PEX, meaning that the PEX will be executable in all of the supported environments.

Complete platforms should be addresses of file targets that point to files that contain complete platform JSON as described by Pex (https://pex.readthedocs.io/en/latest/buildingpex.html#complete-platform).

resolve

field.type_hint
required

The resolve from [python].resolves to use.

If not defined, will default to [python].default_resolve.

All dependencies must share the same value for their resolve field.
