Using Python Interpreter and running Python Code on Docker Container and creating httpd service using docker

firstly your system should have docker installed then follow the steps below…

A Docker image is the blueprint of Docker containers that contains the application and everything you need to run the application. A container is a runtime instance of an image.

In this tutorial, we will explain what Dockerfile is, how to create one, and how to build a Docker image with Dockerfile.

What is Dockerfile?

A Dockerfile is a text file that contains all the commands a user could run on the command line to create an image. It includes all the instructions needed by Docker to build the image.

Docker images are made up of a series of filesystem layers representing instructions in the image’s Dockerfile that makes up an executable software application.

Create a Dockerfile

RUN dnf update
    dnf install python36 -y
    dnf install net-tools vim which -y
    dnf clean

build the image

docker build -t IMAGE_NAME(to build the image)
-docker build -t myweb:v1

check if the image is created

docker run -it --name NAME_OF_CONTAINER IMAGE_NAME

run the docker file

python3 FILENAME.py

Configuring HTTPD Server on Docker Container

TO ACCESS THE DOCKER IN YOUR SYSTEM YOU NEED TO HAVE THE DOCKER INSTALLED AND INSTALL HTTPD

docker run -it --name NAME_OF_CONATINER -p 4444:80 centos

After install httpd in the Docker container.

dnf install httpd -y

start the service

/usr/sbin/httpd

• By default systemclt command doesn’t present in the docker container, so we need to run the file of httpd.
• If you want to permanent httpd service.
• Go to /root/.bashrc file and type :

/usr/sbin/httpd
