2.25.1. Method 1. Docker pull python:3.5

Find Docker Hub Python image on:

` <../wp-content/uploads/2016/06/B32A6862-3599-4B41-A8EA-05A361000865.jpg>` __

You can view other versions of python through Sort by. The default is the latest version. python:latest .

In addition, we can use the docker search python command to view the available versions:

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

After waiting for the download to be completed, we can find an image with a REPOSITORY of python and a label of 3.5 in the local image list.

2.25.2. Method 2. Build through Dockerfile

创建 Dockerfile< / p >

First, create the directory python, which will be used to store the following related things.

runoob@runoob:~$ mkdir -p ~/python ~/python/myapp

The myapp directory will be mapped to the application directory configured by the python container.

Go to the python directory you created and create the Dockerfile.

FROM buildpack-deps:jessie # remove several traces of debian python RUN apt-get purge -y python.* # http://bugs.python.org/issue19846 # > At the moment, setting "LANG=C" on a Linux system *fundamentally breaks Python 3*, and that's not OK. ENV LANG C.UTF-8 # gpg: key F73C700D: public key "Larry Hastings " imported ENV GPG_KEY 97FC712E4C024BBEA48A61ED3A5CA953F73C700D ENV PYTHON_VERSION 3.5.1 # if this is called "PIP_VERSION", pip explodes with "ValueError: invalid truth value ''" ENV PYTHON_PIP_VERSION 8.1.2 RUN set -ex \ && curl -fSL "https://www.python.org/ftp/python/${PYTHON_VERSION%%[a-z]*}/Python-$PYTHON_VERSION.tar.xz" -o python.tar.xz \ && curl -fSL "https://www.python.org/ftp/python/${PYTHON_VERSION%%[a-z]*}/Python-$PYTHON_VERSION.tar.xz.asc" -o python.tar.xz.asc \ && export GNUPGHOME="$(mktemp -d)" \ && gpg --keyserver ha.pool.sks-keyservers.net --recv-keys "$GPG_KEY" \ && gpg --batch --verify python.tar.xz.asc python.tar.xz \ && rm -r "$GNUPGHOME" python.tar.xz.asc \ && mkdir -p /usr/src/python \ && tar -xJC /usr/src/python --strip-components=1 -f python.tar.xz \ && rm python.tar.xz \ \ && cd /usr/src/python \ && ./configure --enable-shared --enable-unicode=ucs4 \ && make -j$(nproc) \ && make install \ && ldconfig \ && pip3 install --no-cache-dir --upgrade --ignore-installed pip==$PYTHON_PIP_VERSION \ && find /usr/local -depth \ \( \ \( -type d -a -name test -o -name tests \) \ -o \ \( -type f -a -name '*.pyc' -o -name '*.pyo' \) \ \) -exec rm -rf '{}' + \ && rm -rf /usr/src/python ~/.cache # make some useful symlinks that are expected to exist RUN cd /usr/local/bin \ && ln -s easy_install-3.5 easy_install \ && ln -s idle3 idle \ && ln -s pydoc3 pydoc \ && ln -s python3 python \ && ln -s python3-config python-config CMD ["python3"]    
 Create an image through Dockerfile and replace it with your own name: 
 
 
 
runoob@runoob:~/python$ docker build -t python:3.5 . 
 
 
 
 After the creation is completed, we can find the newly created image in the local image list: 
 
 
 
runoob@runoob:~/python$ docker images python:3.5 REPOSITORY TAG IMAGE ID CREATED SIZE python 3.5 045767ddf24a 9 days ago 684.1 MB 
 
 
 
 
 Use python mirroring  
 
 Create a helloworld.py file in the ~ / python/myapp directory as follows: 
 
 
 
#!/usr/bin/python print("Hello, World!"); 
 
 
 
  
 
  2.25.3.  Run the container  
 
 
 
runoob@runoob:~/python$ docker run -v $PWD/myapp:/usr/src/myapp -w /usr/src/myapp python:3.5 python helloworld.py 
 
 
 
 Command description: 
 
  -v $PWD/myapp:/usr/src/myapp:  Mount the myapp in the current directory in the host to the / usr/src/myapp of the container. 
 
  -w /usr/src/myapp:  Specify that the / usr/src/myapp directory of the container is the working directory. 
 
  python helloworld.py:  Use the container’s python command to execute the helloworld.py file in the working directory. 
 
 Output result: 
 
 
 
Hello, World!

 最近几年来，地理信息系统无论是在理论上还是应用上都处在一个飞速发展的阶段。 GIS被应用于多个领域的建模和决策支持，如城市管理、区划、环境整治等等，地理信息成为信息时代重要的组成部分之一； “数字地球”概念的提出，更进一步推动了作为其技术支撑的GIS的发展。 与此同时，一些学者致力于相关的理论研究，如空间感知、空间数据误差、空间关系的形式化等等。 这恰好说明了地理信息系统作为应用技术和学科的两个方面，并且这两个方面构成了相互促进的发展过程。
