Hello friends! i like to share with you a simple project.

0. Introduction

syncplay is a Client/server to synchronize media playback on mpv/VLC/MPC-HC/MPC-BE on many computers. small feature we have.

Practicing Docker

1. Lets do it💥

As you know i really love raspberry pi, but idea to install Client/server having not ui in the raspberry. But anyways. I use my laptop and my raspberry.

Following this tutorial How to setup Syncplay server on Ubuntu 20.04. I realize there is a way to improve using docker.

The real repository has not a dockerfile.

Then i will do a dockerfile.

ARG PYTHON="python:3.10-alpine3.18"
FROM ${PYTHON} AS builder
ENV SYNCPLAY="1.7.3"
RUN apk add gcc musl-dev libffi-dev
RUN sh -c '[ $(getconf LONG_BIT) -eq 64 ] || apk add cargo openssl-dev'
RUN wget https://github.com/Syncplay/syncplay/archive/v${SYNCPLAY}.tar.gz -O- | tar xz
WORKDIR ./syncplay-${SYNCPLAY}/
RUN cat /dev/null > requirements_gui.txt
RUN SNAPCRAFT_PART_BUILD=1 pip wheel --wheel-dir /wheels/ ./ #Build Python Wheels

In this part prepares a build environment for Syncplay by installing necessary dependencies, downloading the source code, and building Python wheels

FROM ${PYTHON} AS syncplay
WORKDIR /wheels/
RUN pip wheel PyYaml #Build Wheel for PyYAML
COPY --from=builder /wheels/ /wheels/ #Copy Wheels from Builder
WORKDIR /release/local/lib/
RUN mkdir $(basename /usr/local/lib/python3.*/) && cd ./python3.*/ && \
    ls /wheels/*.whl | xargs -P0 -n1 unzip -d ./site-packages/
COPY ./boot.py /release/bin/syncplay

It creates necessary directories, building and installing dependencies, and copying an entry point script.

FROM ${PYTHON}
RUN sh -c '[ $(getconf LONG_BIT) -eq 64 ] || apk add --no-cache libgcc' # Conditional Package Installation
COPY --from=syncplay /release/ /usr/
ENV PYTHONUNBUFFERED=1 #not buffered output
EXPOSE 8999
WORKDIR /data/
ENTRYPOINT ["syncplay"] #Set Entry Point

2. Testing the result🖊️
