python-build

Python Build - Dagger Module

Python build, lint, test, and typecheck utilities for Dagger pipelines.

Installation

dagger install github.com/telchak/daggerverse/python-build

Functions

Function	Description
build	Build a Python project and return the source with dist/
lint	Lint a Python project (ruff, flake8, pylint)
test	Run tests (pytest, unittest)
typecheck	Type-check a Python project (mypy, pyright)
install	Install project dependencies

Caching

All functions mount pip and uv cache volumes by default (dag.cache_volume("python-pip") and dag.cache_volume("python-uv")) to speed up repeated dependency installs. You can pass custom cache volumes to share across modules:

# Share cache volumes across python-build and other Python modules
pip_cache = dag.cache_volume("my-shared-pip")
uv_cache = dag.cache_volume("my-shared-uv")

result = await dag.python_build().build(source=source, pip_cache=pip_cache, uv_cache=uv_cache)
output = await dag.python_build().lint(source=source, pip_cache=pip_cache, uv_cache=uv_cache)

# CLI: caching is automatic, no extra flags needed
dagger call build --source=.

Usage

Build

dagger call build --source=.

Python Example

from dagger import dag

# Build
result = await dag.python_build().build(source=source)

# Lint with ruff
output = await dag.python_build().lint(source=source, tool="ruff")

# Run tests
output = await dag.python_build().test(source=source)

# Type-check
output = await dag.python_build().typecheck(source=source, tool="mypy")

# Install dependencies
source_with_deps = await dag.python_build().install(source=source)
