Docker镜像构建：Ubuntu18.04+python3.10

1、编写 Dockerfile

# 使用Ubuntu 18.04作为基础镜像
FROM ubuntu:18.04
 
RUN apt-get update && apt-get install -y \
    build-essential \
    curl \
    zlib1g-dev \
    libssl-dev \
    && rm -rf /var/lib/apt/lists/*
 
ENV PYTHON_VERSION=3.10.8
 
RUN curl -O https://www.python.org/ftp/python/${PYTHON_VERSION}/Python-${PYTHON_VERSION}.tar.xz \
    && tar -xf Python-${PYTHON_VERSION}.tar.xz \
    && rm Python-${PYTHON_VERSION}.tar.xz
 
RUN cd Python-${PYTHON_VERSION} \
    && ./configure --enable-optimizations \
    && make -j$(nproc) \
    && make install . \
    && cd - \
RUN rm -rf Python-${PYTHON_VERSION}
 
ENV PATH="/usr/local/bin:${PATH}"

2、构建Docker镜像，可自定义名称如：ubuntu1804_py310

docker build -t ubuntu1804_py310 .

3、运行构建好的Docker镜像

docker run -it ubuntu1804_py310 bash

4、保存Docker镜像到服务器(打tag)

docker tag ubuntu1804_py310:latest nexus.your_server.com:8082/ubuntu1804_py310:latest
