Python

Python is an interpreted, interactive, object-oriented, open-source programming language. It incorporates modules, exceptions, dynamic typing, very high level dynamic data types, and classes. Python combines remarkable power with very clear syntax. It has interfaces to many system calls and libraries, as well as to various window systems, and is extensible in C or C++. It is also usable as an extension language for applications that need a programmable interface. Finally, Python is portable: it runs on many Unix variants, on the Mac, and on Windows 2000 and later.

How to use this Makejail

Create a Containerfile in your Python app project

FROM ghcr.io/appjail-makejails/python:15.1-3

WORKDIR /app

COPY requirements.txt ./
RUN python3 -m ensurepip && \
    python3 -m pip install --no-cache-dir -r requirements.txt

COPY . .

CMD [ "python3", "./your-daemon-or-script.py" ]

or (if you need to use Python 2):

FROM ghcr.io/appjail-makejails/python:15.1-2

WORKDIR /app

COPY requirements.txt ./
RUN python2 -m ensurepip && \
    python2 -m pip install --no-cache-dir -r requirements.txt

COPY . .

CMD [ "python2", "./your-daemon-or-script.py" ]

You can then build and run the OCI image:

$ buildah build --network=host -t my-python-app .
$ appjail oci run \
    -o overwrite=force \
    -o ephemeral \
    -o alias \
    -o ip4_inherit \
    localhost/my-python-app my-python-app

Run a single Python script

For many simple, single file projects, you may find it inconvenient to write a complete Containerfile. In such cases, you can run a Python script by using the Python Docker image directly:

$ appjail oci run \
    -o overwrite=force \
    -o ephemeral \
    -o alias \
    -o ip4_inherit \
    -o fstab="$PWD /myapp" \
    -w /myapp \
    ghcr.io/appjail-makejails/python:15.1-3 my-python-app \
    python3 your-daemon-or-script.py

or (again, if you need to use Python 2):

$ appjail oci run \
    -o overwrite=force \
    -o ephemeral \
    -o alias \
    -o ip4_inherit \
    -o fstab="$PWD /myapp" \
    -w /myapp \
    ghcr.io/appjail-makejails/python:15.1-2 my-python-app \
    python2 your-daemon-or-script.py

OCI image and Makejail

This repository includes a small Makejail that ultimately uses the OCI image, in case you prefer to use appjail-makejail(5).

$ appjail makejail \
    -j python \
    -f gh+AppJail-makejails/python \
    -o container="args:--pull"
...
$ appjail cmd jexec python python

Notes

1. The latest tag refers to the default version of Python in the FreeBSD ports, not the latest version of Python.
2. The ideas present in the Docker image of Python are taken into account for users who are familiar with it.
