Installing Docker Engine on Rocky Linux 9: A Step-by-Step Guide
In the realm of modern IT, speed, security, and cost-efficiency are paramount for large organizations. One solution that aligns perfectly with these needs is Docker Engine on Rocky Linux 9.
Rocky Linux 9, a direct, binary-compatible downstream of Red Hat Enterprise Linux 9, provides a stable foundation for Docker, offering the same level of enterprise features as RHEL. This makes it an ideal choice for running Docker Engine, especially in enterprise-grade environments.
To connect to the instance, use SSH on Linux/macOS or PuTTY on Windows (downloadable from [https://www.putty.org](https://www.putty.org)). Once connected, you can launch the server by clicking "Create Instance" and find the instance's IP address in the Resources section.
Rocky Linux 9 offers several key benefits when it comes to deploying Docker containers. For instance, Docker containers launch in seconds, enabling rapid and frequent software releases or updates, a crucial aspect for enterprises seeking agility and continuous delivery.
Enhanced security is another advantage. Docker provides application isolation that reduces the attack surface. It supports hardened images, image scanning, and signed images to maintain a secure environment. Docker also offers enterprise-grade support with SLA-backed security updates to quickly mitigate critical vulnerabilities.
Scalability and portability are additional benefits. Docker containers can be easily scaled up or down and migrated across different cloud providers or infrastructure without compatibility issues, providing vital enterprise flexibility and workload management.
Cost efficiency is another factor to consider. By running containers instead of full virtual machines, Docker maximizes hardware utilization and reduces infrastructure costs, enabling enterprises to optimize resource allocation.
Consistency and reproducibility are also key benefits. Docker ensures consistent environments for development, testing, and production, reducing bugs related to environment differences and improving reliability of software delivery pipelines.
Docker integrates smoothly with CI/CD tools like Jenkins and GitLab CI, streamlining automation and collaboration across software development cycles, which accelerates innovation and improves product quality.
Moreover, Docker offers professional enterprise support tailored to mission-critical applications on hardened images, with rapid response times and proactive security management — crucial for maintaining operational continuity in complex environments.
In summary, Docker Engine on Rocky Linux 9 enables enterprises to deploy applications quickly and securely with consistent environments, while benefiting from strong support, seamless scalability, and cost savings — all critical factors for modern, enterprise-grade IT infrastructure.
Rocky Linux 9 supports OverlayFS and cgroups v2 out of the box, making it an excellent choice for Docker-based projects. Shape.Host offers fast, scalable cloud VPS solutions for such projects. To create a server on Shape.Host, simply navigate to the top menu, choose "Instance", select a data center (e.g., Frankfurt, Dallas), choose Rocky Linux 9 (64-bit) as the operating system, and pick a hosting plan with at least 2 CPUs, 2 GB RAM, and 20 GB SSD.
To install Docker Engine on Rocky Linux 9, follow the provided commands, which include updating the system packages, installing necessary tools and dependencies, creating the yum repository directory, adding the Docker repository, installing Docker Engine and its components, starting the Docker service, enabling it to start automatically on boot, and checking the status of the Docker service.
For those who may need to uninstall Docker, the provided commands can also be used for this purpose.
