Docker is an open-source platform used by developers worldwide to automate processes such as deployment, application management, and scaling with the aid of containerization. Created by Docker, Inc. it has earned its huge popularity in the software community.
Portability, efficiency, Isolation, Scalability, Security, and easy management are some of the prominent features of this platform that makes people go for it. Overall, Docker simplifies the application deployment process, increases development productivity, and enhances the scalability and reliability of applications, making it a valuable tool for modern software development and DevOps practices.
Advantages of Docker Compose
Multi-Container Orchestration: Docker Compose simplifies managing multi-container applications, allowing you to define, configure, and run multiple containers as a single service.
Version Control: Docker Compose YAML files offer version-controlled configuration, ensuring consistency and reproducibility across development, testing, and production environments.
Easy Deployment: Compose enables straightforward deployment with a single command, streamlining the process of launching complex applications with interconnected services.
Service Scaling: Scaling services in Docker Compose is effortless, allowing you to replicate containers and adjust resources to meet varying workloads.
Network Management: Compose simplifies networking, facilitating communication between containers and enabling seamless connections within defined networks.
Installation Process
The good thing about this platform is its ability to be compatible with every operating system. We can use this one in Linux distributions as well.
Update Debian 12
Updating Debian will ensure we have the latest packages and will also simplify the Docker Compose installation process.
Install Dependency Packages
To install Docker compose, we need to install all the dependency packages.
Add Docker GPG key
Now we will import and add the official Docker GPG key.
Add Docker Repository in Debian 12
Now we will be adding the Docker repository in our Debian 12.
Install Docker on Debian 12
Now we need to install Docker. For that, we have a command available as follows.
$ sudo apt install docker-ce docker-ce-cli containerd.io docker-compose-plugin -y
[/cc]
Enable Docker
Now we need to enable Docker in our Debian 12.
$ sudo systemctl enable –now docker
[/cc]
Check Docker Version
To check the docker version in Debian 12, we will be using the following command.
$ docker version
[/cc]
Uninstall Docekr
The docker uninstallation process is really simple. We have remove command that will uninstall it.
To remove all the remaining packages automatically, we have a command as
Conclusion
Docker is an engine that allows programmers, developers and system architects to create different containers and then deploy multiple applications at the same time. This platform can be used in almost every system.
