Docker is a free and open-source tool that allows you to build and run containers on your Linux system. It allows you to create lightweight and portable application images that run on any platform.
Docker Compose is a free and open-source tool that allows you to define, visualize, and run multiple applications in a containerized environment. It uses a YAML file to define different applications and services. After defining the services in the YAML file, you can start all of them using a single command.
In this post, we will show you how to install Docker and Docker Compose in Rocky Linux 10.
Step 1 – Install Docker CE
By default, the Docker package is not included in the RockyLinux default repository, so you will need to create a Docker CE repo.
You can create it using the following commands:
dnf update -y dnf config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
Next, install Docker CE by running the following command:
dnf install docker-ce -y
Once Docker is installed, start the Docker service and enable it to start at system reboot.
systemctl start docker systemctl enable docker
You can verify the status of the Docker service using the following command:
systemctl status docker
Sample output:
ā docker.service - Docker Application Container Engine Loaded: loaded (/usr/lib/systemd/system/docker.service; disabled; preset: disabled) Active: active (running) since Sun 2025-10-19 23:18:53 EDT; 14s ago Invocation: a8e3c991e424460bb982889cd8905567 TriggeredBy: ā docker.socket Docs: https://docs.docker.com Main PID: 42672 (dockerd) Tasks: 9 Memory: 22.4M (peak: 26.3M) CPU: 307ms CGroup: /system.slice/docker.service āā42672 /usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock
To verify the Docker version with additional information, run the following command:
docker info
You will get the following output:
Client: Docker Engine - Community Version: 28.5.1 Context: default Debug Mode: false Plugins: buildx: Docker Buildx (Docker Inc.) Version: v0.29.1 Path: /usr/libexec/docker/cli-plugins/docker-buildx compose: Docker Compose (Docker Inc.) Version: v2.40.1 Path: /usr/libexec/docker/cli-plugins/docker-compose Server: Containers: 0 Running: 0 Paused: 0 Stopped: 0 Images: 0 Server Version: 28.5.1 Storage Driver: overlay2 Backing Filesystem: extfs
Step 2 – Verify Docker Installation
After installing Docker, you will need to test whether it’s working.
You can use Dockerās hello-world container to test Docker.
docker run hello-world
This will download the hello-world docker image to your system:
Unable to find image 'hello-world:latest' locally latest: Pulling from library/hello-world 2db29710123e: Pull complete Digest: sha256:9ade9cc2e26189a19c2e8854b9c8f1e14829b51c55a630ee675a5a9540ef6ccf Status: Downloaded newer image for hello-world:latest Hello from Docker! This message shows that your installation appears to be working correctly. To generate this message, Docker took the following steps: 1. The Docker client contacted the Docker daemon. 2. The Docker daemon pulled the "hello-world" image from the Docker Hub. (amd64) 3. The Docker daemon created a new container from that image which runs the executable that produces the output you are currently reading. 4. The Docker daemon streamed that output to the Docker client, which sent it to your terminal. To try something more ambitious, you can run an Ubuntu container with: $ docker run -it ubuntu bash Share images, automate workflows, and more with a free Docker ID: https://hub.docker.com/ For more examples and ideas, visit: https://docs.docker.com/get-started/
You can verify the downloaded image using the following command:
docker images
You will get the following output:
REPOSITORY TAG IMAGE ID CREATED SIZE hello-world latest feb5d9fea6a5 2 weeks ago 13.3kB
Step 3 – Install Docker Compose
Docker Compose is already installed with the Docker CE installation. You can verify the Docker Compose version using the following command:
docker compose version
You will get the following output:
Docker Compose version v2.40.1
Step 4 – Remove Docker and Docker Compose
If you want to remove the Docker package from your system, first stop the Docker service using the following command:
systemctl stop docker
Next, remove Docker and Docker Compose using the following command:
dnf remove docker-ce -y
Conclusion
In the above guide, we explained how to install Docker and Docker Compose on RockyLinux 10. You can now start creating a YAML for your application and deploy it in the containerized environment. Give it a try on your dedicated server from Atlantic.Net!
