scys/pyinstaller repository overview

⁠PyInstaller

Docker image that can build single file Python apps with PyInstaller⁠ for Alpine Linux⁠.

Alpine uses musl⁠ instead of glibc⁠. The PyInstaller bootloader for Linux 64 that comes with PyInstaller is made for glibc. This Docker image builds a bootloader with musl.

This Docker image also provides a clean way to build PyInstaller apps in an isolated environment.

⁠Usage

⁠Building A PyInstaller Package

To build a Python package, create a Docker container with your source mounted as a volume at /src:

docker run --rm \
    -v "${PWD}:/src" \
    six8/pyinstaller-alpine \
    --noconfirm \
    --onefile \
    --log-level DEBUG \
    --clean \
    example.py

If a requirements.txt file is found in your source directory, the requirements will automatically be installed with pip.

This will output a built app to the dist sub-directory in your source directory. The app can be ran on an Alpine OS:

./dist/example

⁠Encrypting Your App

You can use PyInstaller to obfuscate your source with encryption⁠. To use a specific key, pass a 16 character string with the --key {key-string} parameter. A non-standard feature of this Docker image is that you can use --random-key to use a random key:

docker run --rm \
    -v "${PWD}:/src" \
    six8/pyinstaller-alpine \
    --onefile \
    --random-key \
    --clean \
    example.py

⁠Reproducible Build

If you want a Reproducible Build⁠ when your source has not changed, you can pass a PYTHONHASHSEED env var for consistent randomization for internal data structures:

docker run --rm \
    -v "${PWD}:/src" \
    -e PYTHONHASHSEED=42 \
    six8/pyinstaller-alpine \
    --onefile \
    --clean \
    example.py

cksum dist/example | awk '{print $1}'

⁠Building Docker Image

If you'd like to build the Docker image yourself:
