Installing Docker Engine on Alma Linux 9: A Step-by-Step Guide
In the realm of containerization, Docker Engine on AlmaLinux 9 is making waves as a reliable and efficient solution for building, shipping, and running applications. This combination offers a high-performance container platform on a secure, predictable, and community-supported enterprise operating system.
AlmaLinux 9, a derivative of Red Hat Enterprise Linux (RHEL), provides a stable and secure environment. Coupled with Docker Engine, it offers reliable containerization for enterprise workloads. The official container image for AlmaLinux offers a minimal, enterprise-ready base layer for application containers.
One of the key benefits of using Docker Engine on AlmaLinux 9 is its native integration and performance. Docker Engine runs directly on the Linux host without virtualization overhead, ensuring native performance and efficiency. This is particularly beneficial in production environments where resource efficiency is crucial.
Moreover, Docker Engine on AlmaLinux 9 consumes fewer resources compared to solutions that operate within a virtualized environment. This is advantageous for environments where resource constraints are a concern.
Integration with Linux system services further enhances the overall containerization experience. This seamless integration facilitates efficient deployment and scaling of containers.
Security and compliance are also prioritized. Docker on AlmaLinux 9 can be integrated with various security subsystems, enhancing the security posture of containerized applications and ensuring compliance with enterprise security standards.
Docker adheres to OCI (Open Container Initiative) standards, making it interoperable with other tools and runtimes like Podman, CRI-O, and Kubernetes. It also supports OpenSCAP, audit profiles, and FIPS-mode, making it useful in regulated industries.
To set up a server instance for Docker Engine on AlmaLinux 9, select "Instance" and choose a hosting plan with at least 2 CPUs, 2 GB RAM, and 20 GB SSD. After the setup finalization, the IP address can be found under the "Resources" tab.
To connect to the instance on Linux/macOS, open a terminal and connect via SSH using the IP address. For Windows users, download and install PuTTY, open it, and paste the instance's IP into the Host Name field.
Installation of Docker Engine on AlmaLinux 9 involves a series of commands for system update, dependency installation, repository creation, and Docker installation. After successful installation, the official hello-world container can be run to verify it is working properly.
Uninstalling Docker from the system can be done by running specific commands. Docker can also be configured to operate with rootless mode on AlmaLinux, enhancing security for multi-user systems.
In summary, Docker Engine on AlmaLinux 9 provides a robust, efficient, and secure containerization platform suitable for a wide range of enterprise and development environments. Shape.Host offers fast, secure, and reliable cloud instances perfect for container-based environments to set up a server instance for Docker Engine on AlmaLinux 9.
Data-and-cloud-computing technology is leveraged to run Docker Engine on AlmaLinux 9, creating a cloud-based container platform for efficient and secure application deployment. The integration of Docker Engine with AlmaLinux 9 technology enables native performance and resource efficiency, making it ideal for production environments and resource-constrained scenarios.
