Docker on Manjaro

Docker is a powerful and popular platform for developing, testing, and deploying applications in containers. Manjaro is a user-friendly Linux distribution that is based on Arch Linux. In this guide, we will explore how to install and use Docker on Manjaro Linux.

Prerequisites

Before you start, ensure that your system is up to date and you have administrative access.

You can update your system by running the following command in the terminal:

sudo pacman -Syu

Installing Docker

To install Docker on Manjaro Linux, follow these steps:

1. Open the terminal.

2. Install Docker by running the following command:

   sudo pacman -S docker
   

   This will install Docker on your system.

3. Enable and start the Docker service by running the following commands:

   sudo systemctl enable docker.service
   sudo systemctl start docker.service
   

   This will ensure that Docker is started when your system boots and will start Docker now.

4. Verify that Docker has been installed correctly by running the following command:

   sudo docker info
   

   This command will display information about your Docker installation.

Building Docker Images

You can use Docker to build images that contain your application and all its dependencies.

To build a Docker image, follow these steps:

1. Create a Dockerfile in your project directory. This file contains instructions for Docker to build your image.

   FROM python:3.8-slim-buster
   
   WORKDIR /app
   
   COPY . .
   
   RUN pip install --no-cache-dir -r requirements.txt
   
   CMD ["python", "app.py"]
   

2. Build the Docker image by running the following command:

   sudo docker build -t myapp .
   

   This will build a Docker image called "myapp".

3. Run the Docker image by running the following command:

   sudo docker run -p 5000:5000 myapp
   

   This will run the Docker image and map port 5000 on your host machine to port 5000 inside the container.

Conclusion

Docker is a powerful tool for building, testing, and deploying applications in containers. By installing Docker on Manjaro Linux, you can take advantage of this technology to streamline your development and deployment workflows.
