The fact that Podman is OCI-compliant, with Docker files and images supported, means that you can easily switch from Docker or other container engines to Podman. In comparison to Docker, which provides a compatible API that makes switching easy, Podman displays a wider range of integration with developer's tools.įrom a security standpoint, Podman offers more protection. Integrating other development tools might also be a reason to consider Podman. So, you may be able to take advantage of Podman's more features.
The installation of Rootless Containers on User Namespaces will require additional features to run on your machine. Thus, Podman's Docker daemon functionality is taken over by the system.ĭue to the fact that Podman is a daemon-less container engine, you have an excellent security advantage due to the fact that containers depend on user privileges. By integrating directly with systemD (system daemon), Podman runs containers in the background without root privileges. It is, however, daemon-less and does not require root privileges to run the Podman Container Engine. The Podman container engine can be used on Linux machines to develop, maintain, and run OCI containers just like Docker.
Here we go! Table Of ContentsĪ virtualization platform offered by RedHat called Podmanis an open-source alternative. In addition to requiring compliance with open container initiatives (OCI) and Kubernetes Container Runtime Interfaces (CRI), the two are made up of two sets of standards.ĭocker’s ecosystem is robust and provides an extensive toolkit for managing containerization processes, but there are other alternatives that extend beyond Docker.Īs a drop-in replacement for the Docker ecosystem, we'll look at a few Docker alternatives in this article. There are many other projects that are part of the container ecosystem, and Docker is only part of the container ecosystem. Docker is a Linux-based open-source containerization technology.ĭocker is generally misunderstood to be only about containers. Millions of applications currently use Docker, one of the most useful tools in this space.Ī Docker container can be used to build, run, inspect, and manage container images for developing applications. A container is a separate unit of software that encapsulates the software and libraries of an application, including its dependencies and its code.Īs a means of developing and managing stable applications, many organisations are adopting containers.
