Docker install Python

Method 1, docker pull python:3.5

Find Python images on Docker Hub:

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

In addition, we can also 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]

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]

Here we pull the official image, labeled 3.5

runoob@runoob:~/python$ docker pull python:3.5

After the download is completed, we can find the image with the REPOSITORY of python and the label of 3.5 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

Method 2: Build through Dockerfile

Create Dockerfile</p>

First, create the directory python to store related things later.

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

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

Enter the created python directory and create a Dockerfile.

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 image we just created 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 mirror

Create a helloworld.py file in the ~/python/myapp directory with the following code:

#!/usr/bin/python

print("Hello, World!");

Run 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 myapp in the current directory on the host to /usr/src/myapp in the container.

-w /usr/src/myapp: Specify the /usr/src/myapp directory of the container as the working directory.

python helloworld.py: Use the container's python command to execute the helloworld.py file in the working directory.

Output results:

Hello, World!
