The container landscape in 2025 highlights a clear trade-off between security and usability. Docker continues to dominate due to its simplicity, mature tools, and vast ecosystem. It’s ideal for developers seeking convenience and seamless integration across platforms. In contrast, Podman appeals to teams prioritizing security and system-level control, with its rootless architecture and tighter Linux integration. Organizations must balance usability with operational security. For many, the answer is using Docker during development and Podman in production. This division allows teams to benefit from both environments, aligning workflows with best practices while minimizing risk and maintaining operational efficiency. 1. A Docker stronghold — but not without challengers Docker remains the most widely used container platform in 2025. With over 20 million developers actively using it, Docker’s ecosystem spans nearly every development tool, CI/CD service, and cloud provider—...

Difference between Docker Run and Start Commands?

January 09, 2025

Docker Online Training has become a powerful tool that simplifies the process of managing software applications. Docker provides a range of commands that allow users to interact with containers, and two of the most commonly used commands are docker run and docker start . These commands play essential roles in working with containers, but they serve different purposes. Understanding the difference between the docker run and docker start commands is crucial for anyone who is using Docker to manage applications and services. Introduction: Docker Run vs. Docker Start When working with Docker, it’s important to know the distinction between the docker run and docker start commands. These two commands might seem similar, but they are used in different scenarios. Docker containers are used to isolate applications and their dependencies, which makes them portable and easy to deploy. The docker run command ...

Difference between Privileged and Non-Privileged Containers

June 23, 2025

The Privileged and Non-Privileged Containers world of containerization, security, and access control is a crucial concern . While containers offer a lightweight and flexible alternative to traditional virtualization, their configuration can dramatically impact system security. One of the key distinctions in container security lies in the choice between privileged and non-privileged containers. Understanding this difference is essential for system administrators, developers, and DevOps professionals who aim to balance performance, flexibility, and security in their environments. What Are Privileged Containers? A privileged container is one that runs with extended permissions. When a container is started in privileged mode, it is granted access to all the devices on the host and operates almost like a virtual machine with root access to the host system. This level of access allows the container to perform a wide range of operations that are typically ...
