Managing your Docker containers and environments on Rocky Linux doesn’t have to be complex. A powerful, open-source tool exists that provides a user-friendly web interface, making deployment, configuration, and management significantly easier. This tool is essential for anyone working with containers, simplifying tasks from basic operations to more advanced setups.
To get this powerful container management interface up and running on your Rocky Linux system, you’ll first need to ensure Docker is installed. If you don’t have it already, the process typically involves adding the official Docker repository to your system and then installing the necessary packages using your system’s package manager. Make sure the Docker service is started and enabled to run on boot.
Once Docker is ready, installing the container management tool itself is straightforward using Docker commands. The recommended approach is to run it as a Docker container itself, leveraging Docker’s own capabilities for deployment.
The installation process involves a few key steps:
- Create a persistent volume: This is crucial for ensuring your configuration and data persist even if the container is stopped or removed. A dedicated Docker volume is created for this purpose.
- Run the container: You’ll use the
docker runcommand. This command pulls the necessary image, starts the container in detached mode (-d), maps a specific port (commonly 9000) from the container to your host machine so you can access the web interface, and mounts the persistent volume created earlier to the appropriate directory inside the container. You also need to mount the Docker socket (/var/run/docker.sock) to allow the tool to interact with your Docker daemon.
After executing the docker run command, the container will start in the background. You can then access the web interface by opening a web browser and navigating to your Rocky Linux server’s IP address or hostname followed by the mapped port (9000).
The first time you access the interface, you will be prompted to create an administrator user. You’ll set up a username and a strong password. Following this, you’ll typically be asked to connect to a Docker environment. For most users installing on a single server, connecting to the local Docker environment is the correct choice.
With the initial setup complete, you gain immediate access to a comprehensive dashboard. From here, you can easily deploy applications from App Templates, manage your existing containers, inspect images, configure networks, handle volumes, and much more, all through an intuitive graphical interface. This drastically reduces the need to constantly use the Docker CLI, making container management on Rocky Linux efficient and accessible for everyone.
