Step-by-Step Process or Creating and Using Dockerfile and Docker Compose File

Creating a Docker Compose File: A Step by Step Guide

Step-1: Launch EC2 Instance

Step 2: Install Docker

Now install docker in our local machine by using following commands

sudo yum -y install docker

Step 3: Create Dockerfile

Here is the dockerfile to build a Docker image

FROM amazonlinux:latest

RUN yum update -y

yum install -y git python3-pip

RUN git clone https://github.com/Sada-Siva-Reddy07/fish.git /fish

WORKDIR /fish

RUN pip3 install –no-cache-dir -r requirements.txt

EXPOSE 2000

CMD [“python”, “app.py”]

Step 4: Build the Docker Image

Now run the below commands to build docker image

docker build -t <filename> .

Step 5: Run the Docker Container

Now the docker container by using following commands

docker run -dt -p 8000:8000 <filename>

Here docker images list by using docker ps.
docker image was successfully build

Docker Compose vs. Dockerfile with Code Examples

Docker is an open-source platform that empowers developers to automate the deployment of applications inside lightweight, portable containers. Containers encapsulate an application and its conditions, ensuring consistency across various conditions, from advancement to production, the Dockerfile and the Docker Compose file are two essential Docker tools that make containerization easier.

A set of instructions for making a Docker image can be found in a text file called a Dockerfile. Each instruction in a Dockerfile creates a layer in the image, ensuring the consistency and reproducibility of the application and its dependencies.

Then again, a Docker Compose file is utilized to define and run multi-container Docker applications. Docker Compose makes it simpler to orchestrate complex applications by allowing users to set up and manage multiple containers, networks, and volumes through the use of a straightforward YAML configuration file

Understanding how to make and utilize Dockerfiles and Docker compose files is essential for anybody seeking to influence Docker for proficient application deployment and the executives. This guide will go over the fundamentals of these tools, show you how to make and use them, and give real-world examples to show how to do so.
