Step-by-Step Process To Deploy Python Application In Docker Compose
Step 1: Launch an Instance
- Go to the AWS console and log in with credentials or create an account
- Now launch an EC2 instance
Now connect with terminal
Step 2: Install Docker
- Install docker by using following commands
sudo yum -y install docker
- Now start and enable docker by using following commands
sudo systemctl start docker
sudo systemctl enable docker
sudo systemctl status docker
Step 3: Install docker-compose
Now install docker compose by using following commands
sudo curl -L https://github.com/docker/compose/releases/download/1.22.0/docker-compose-$(uname -s)-$(uname -m) -o /usr/local/bin/docker-compose
Now change permissions to docker-compose by using following commands
sudo chmod +x /usr/local/bin/docker-compose
+x means we are giving execution permissions only to docker-compose.
Step 4: Create Dockerfile
Now we are creating dockerfile inside this dockerfile we are defining our python application
FROM amazonlinux:latest
# Update packages and install necessary dependencies
RUN yum update -y && \
yum install -y git python3-pip
# Clone the repository
RUN git clone https://github.com/Sada-Siva-Reddy07/fish.git /fish
# Set the working directory
WORKDIR /fish
# Install Python dependencies
RUN pip3 install -r requirements.txt
# Expose port 2000 (if required)
EXPOSE 2000
# Specify the command to run the Python application
CMD ["python3", "./app.py"]
Here is the git repository link you can clone from my git repository if you want
“https://github.com/Sada-Siva-Reddy07/fish.git”.
Step 5: Create Docker-compose file
version: '3.3'
services:
python_app:
build:
context: .
dockerfile: Dockerfile
ports:
- "2000:2000"
Step 6: Build docker Image
- Now build docker image by using following command
docker-compose build
- We can check docker images by using following command
docker-compose images
Step-7: Run the Docker-compose up
Now run the docker-compose up command to run the containers
docker-compose up
Step 7: Verify
Now copy and browse public ip along with port number
Docker Compose for Python Applications: A Comprehensive Guide
In the domain of present day software development, Python has arisen as a powerhouse language, leaned toward for its simplicity, readability, and flexibility. With Python, developers can make a wide cluster of uses, from web services and APIs to data handling pipelines and AI models. Notwithstanding, conveying and overseeing Python applications across different conditions can introduce difficulties, especially with regards to ensuring consistency and reproducibility.
Enter Docker Compose, an instrument that smoothes out the containerization cycle for multi-container Docker applications. Docker Compose improves on the orchestration of interconnected services, giving designers a clear method for defining, running, and managing complex application models, for Python developers, Docker Compose offers a strong tool compartment for containerizing their applications, ensuring portability, versatility, and simplicity of deployment.
In this comprehensive guide, we’ll explore the collaboration between Docker Compose and Python applications. We’ll begin by setting out the basis with an outline of essential terminologies connected with Docker and Docker Compose, laying out a typical comprehension of key concepts. From that point, we’ll leave on a step-by-step journey, directing you through the most common way of containerizing Python applications utilizing Docker Compose, complete with useful guides to show each step en route.
Whether you’re a carefully prepared Python developer hoping to smooth out your deployment work processes or a newbie anxious to saddle the force of containerization, this guide has something for you. Toward the finish of our journey, you’ll have the knowledge and tools to confidently use Docker Compose for containerizing your Python applications, opening additional opportunities for efficiency, versatility, and reliability in your software projects. Thus, how about we take a dive and explore the universe of Docker Compose for Python applications together?
