How to Setup Docker in AlmaLinux

Docker is a popular containerization platform that allows developers to package their applications in containers. Containers are lightweight and portable, making it easy to deploy applications across different environments. In this guide, we’ll show you how to set up Docker on AlmaLinux.

Step 1: Install Docker

The first step is to install Docker on your AlmaLinux system. You can install Docker using the following command:

sudo dnf install docker-ce docker-ce-cli containerd.io

This command will install the latest version of Docker on your system.

Step 2: Start the Docker Service

Once Docker is installed, you need to start the Docker service. You can start the Docker service using the following command:

sudo systemctl start docker

You can also enable Docker to start at boot time using the following command:

sudo systemctl enable docker

Step 3: Verify the Docker Installation

To verify that Docker is installed and working correctly, you can run the following command:

sudo docker run hello-world

This command will download a sample Docker image and run a container based on that image. If everything is working correctly, you should see a message that says “Hello from Docker!”

Step 4: Use Docker

Now that Docker is installed and working correctly, you can start using Docker to run containers. You can search for Docker images on Docker Hub, pull Docker images to your local system, and run containers based on those images. Here are some examples:

• Search for an image: sudo docker search IMAGE_NAME
• Pull an image: sudo docker pull IMAGE_NAME
• Run a container: sudo docker run IMAGE_NAME

For more information on how to use Docker, you can refer to the official Docker documentation.

Conclusion

That’s it! You’ve successfully set up Docker on AlmaLinux and can now start using Docker to run containers. Docker is a powerful tool that can help you build, package, and deploy applications in a more efficient and portable way. With Docker, you can easily move your applications between different environments without having to worry about dependencies or compatibility issues.
