docker打包 arm32v7/debian 问题总结

1.架构不同

我的宿主是x86 ,但是打包的是arm架构
安装qemu
sudo apt-get install binfmt-support qemu qemu-user-static
然后使用buildx打包
docker buildx build --no-cache --platform linux/arm/v7 -t tdc_post:1.0.1 . --load
保存tar
docker save -o tdc_post.tar tdc_post:1.0.0

2. 安装库报错

直接pip3 install -r requestments.txt 的时候报错
修改为执行apt-get install python3-xxx

FROM arm32v7/debian AS build


# Run installs
RUN apt-get update && \
    apt-get install -y --no-install-recommends \
    apt-utils \
    python3 \
    python3-pip \
    python3-dev \
    python3-fastapi \
    python3-sqlalchemy

# pip install needed libraries with cert
RUN pip3 install requests --break-system-packages

RUN pip3 install pyyaml --break-system-packages
# Create a directory for the app
WORKDIR /app

# Copy the necessary Python files
COPY . .


# Set the entry point command
CMD ["python3", "start.py"]
