Valuable Features

Docker on CentOS emphasizes container isolation, image-based packaging, and portability. Its fast startup and lightweight containers enhance deployment speed. Users report simplified application deployment, consistency across environments, reduced VM use, resource efficiency, and easier scaling. Time savings of 30-40% are noted. Docker repository streamlines deployment, improving time to market. Some have reported security concerns due to deprecation, while orchestration aids in container management. Lightweight architecture impacts resource utilization.
  • "The compatibility of Docker on CentOS is really smooth, and I have not faced any kind of issue."
  • "Docker on CentOS has positively impacted my organization by making testing easier."
  • "Docker on CentOS has positively impacted my organization because we do not need much resource per application, and our deployment time has decreased, allowing us to avoid using more VMs to host our applications."

Room for Improvement

Docker on CentOS requires enhanced orchestration, better long-term OS lifecycle clarity, and improved synchronization with OS updates. Security and isolation are weaker due to shared kernels, and networking misconfigurations may occur. Stability is affected by rapid disk space consumption, leading to crashes. Monitoring and container metrics need enhancement. Since it is deprecated, there is uncertainty about ongoing support, with Red Hat focusing on Podman, necessitating careful planning for the future use of Docker on CentOS.
  • "Docker sometimes has some network-related issues, such as the host network not working, so we switch to a different type of network, and regarding CentOS, we are not using any support since it is freeware, relying only on documentation which serves as our support."
  • "However, documentation could be improved. Documentation could be made more accessible, more readable, and all those things."
  • "Docker on CentOS can be improved by addressing security concerns, such as sharing the kernel, which leads to weaker isolation than VMs."

ROI

Organizations experienced diverse outcomes using Docker on CentOS. Some reported saving 40 to 50 percent in costs, attributing this to reduced reliance on VMs and the benefits of open-source technologies. Others did not measure the financial impact, and some encountered negative financial outcomes due to deprecation issues, investing time and resources without progress. Overall, most found time-saving benefits, with cost reductions noted by those leveraging open-source advantages. However, metrics for savings varied among users.

Pricing

Docker on CentOS users generally find no licensing costs, as there is no need for a license. Setup is straightforward, involving image creation for applications. The open-source nature implies costs mainly arise from support services. Some mention that while pricing, setup, and licensing are satisfactory, security and deprecation concerns could affect adoption decisions. Price is generally not seen as a barrier.

Popular Use Cases

Docker on CentOS is primarily used for building, packaging, and running containerized applications by DevOps and platform teams. They manage container infrastructure and CI/CD pipelines, leveraging Docker for a range of tasks, including hosting frontend, backend, and database containers. Utilizing Docker for microservices, machine learning pipelines, websites, and backend services is common. Docker on CentOS also supports creating lightweight containers for application deployment and managing multiple software images for improved availability.

Service and Support

Customer service and support for Docker on CentOS involve collaboration with partners who work with Red Hat and Docker teams. Some rely on Amazon's AWS support with quick responses. Many find assistance through online communities for simpler issues. Generally, support is considered effective when involving partners, and online resources often provide necessary aid.

Stability

Docker on CentOS is generally considered stable and suitable for enterprise Linux environments. Some users note it performs well, rating it 8 or 9 out of 10. However, concerns exist regarding CentOS lifecycle changes and the industry's move to Kubernetes and containerd. While many find the platform reliable, some believe it requires improvements and express worries about its maintenance and strategic relevance in the long term.
