For many users, docker is the preferred tool that comes to their minds for containerisation.

Docker is an open-source tool designed to build, deploy, and run applications using containers.

But docker is not the only option to containerise your application in production.

The RedHat podman is one of the most popular substitutes for docker.

Podman is a daemonless, rootless container engine for developing, managing, and running OCI Containers.

Podman containers are more secure as compared to conventional docker containers.

The commands in podman are similar to the the ones used in docker containers.

So in conclusion, use podman if you need additional security and choose docker for its easy to use and vast community support.
