Docker is a containerization technology that allows developers to package and deploy applications in lightweight, portable containers. These containers are isolated from the host operating system, which makes them portable across different environments and eliminates the “works on my machine” problem.

Docker is a popular platform for creating and managing containerized applications; however, several alternatives for Docker can also be used for this purpose. Podman, Kubernetes, Openshift, LXD, Docker Swarm, BuidKit, and Mesos are some of the popular Docker alternatives available in the market today. In this article, we’ll discuss the following three Docker hub alternatives: Podman, Containerd, and LXD.
