Docker 教程 之 Docker 安装 Python 1
Docker 安装 Python
方法一、docker pull python:3.5
查找 Docker Hub 上的 Python 镜像:
可以通过 Sort by 查看其他版本的 python,默认是最新版本 python:latest。
此外,我们还可以用 docker search python 命令来查看可用版本:
runoob@runoob:~/python$ docker search python
NAME DESCRIPTION STARS OFFICIAL AUTOMATED
python Python is an interpreted,... 982 [OK]
kaggle/python Docker image for Python... 33 [OK]
azukiapp/python Docker image to run Python ... 3 [OK]
vimagick/python mini python 2 [OK]
tsuru/python Image for the Python ... 2 [OK]
pandada8/alpine-python An alpine based python image 1 [OK]
1science/python Python Docker images based on ... 1 [OK]
lucidfrontier45/python-uwsgi Python with uWSGI 1 [OK]
orbweb/python Python image 1 [OK]
pathwar/python Python template for Pathwar levels 1 [OK]
rounds/10m-python Python, setuptools and pip. 0 [OK]
ruimashita/python ubuntu 14.04 python 0 [OK]
tnanba/python Python on CentOS-7 image. 0 [OK]
这里我们拉取官方的镜像,标签为3.5
runoob@runoob:~/python$ docker pull python:3.5
等待下载完成后,我们就可以在本地镜像列表里查到 REPOSITORY 为python, 标签为 3.5 的镜像。
runoob@runoob:~/python$ docker images python:3.5
REPOSITORY TAG IMAGE ID CREATED SIZE
python 3.5 045767ddf24a 9 days ago 684.1 MB
方法二、通过 Dockerfile 构建
创建 Dockerfile
首先,创建目录 python,用于存放后面的相关东西。
runoob@runoob:~$ mkdir -p ~/python ~/python/myapp
myapp 目录将映射为 python 容器配置的应用目录。
进入创建的 python 目录,创建 Dockerfile。

CMD ["python3"]
通过 Dockerfile 创建一个镜像,替换成你自己的名字:
runoob@runoob:~/python$ docker build -t python:3.5 .
创建完成后,我们可以在本地的镜像列表里查找到刚刚创建的镜像:
runoob@runoob:~/python$ docker images python:3.5
