Python on the top of Docker

🔅 Setting up Python Interpreter and running Python Code on Docker Container …

Now it’s time to integrate technologies and do fun with programming.

CONTAINERIZATION — It is a concept that is a lightweight alternative to the virtual machine. It runs an operating system with a Bootable Image fastly. It is a UserCase used in companies a lot.

Its tools are — Docker Hub, Marathon, Swarm, Kubernetes, etc.

DOCKER — Docker is a tool that uses O.S. level virtualization to deliver software into packages called containers. Docker uses Bootable images to run the operating system in just 1 second. Docker is a powerful tool made by Solomon Hykes.

Today I am going to run Python Interpreter on top of Docker by using bootable images which will be internally downloaded from DOCKER HUB.

IMAGE

The image i am showing is from Docker Hub and this is the place from where docker will pull the image.I am using Centos image in this task.

Docker Hub

PULL THE IMAGE

“ docker pull centos ” is the command used to download the image on the BaseOS.

pull the image

DOCKER IMAGES ON BASEOS

To see which images are present on our RedHat system we use the “docker images ” command. Here Centos image is downloaded.

check docker images

______________________________

LAUNCH+BOOT+LOGIN INTO CONTAINER

“ docker run -it — name PythonInterpreter centos ” is the drastic command which launch + boot + login into the Operating System in just 1 second. Here you can see that the terminal changed from BaseOS to Docker Container.

Launch + Boot + Login

SELINUX

“ setenforce 0 ” is a command which changes SElinux from targeted to Permissive Mode. In this mode, we can perform all actions and it will not give any security issue.

SELinux mode changed

PYTHON NOT FOUND

See python is not present in the container.

check python is running or not??

______________________________

INSTALL PYTHON

“ yum install python3 ” is the command to install python on a docker container.

install python

______________________________

PYTHON INTERPRETER

“ python3 ” is the command which helps the user to enter into a python interpreter.

python interpreter

MAKE A PYTHON FILE

I am making a python file with [.py] extension and writing a code in it so that we will run it on a docker container.

create a file by vi editor

______________________________

RUN PYTHON PROGRAM FILE

“ python3 file.py” is the command used to run a python program file.

run code

______________________________

EXIT

“ exit ” is a command through which docker container shut and come back to BaseOS terminal.

exit
