A container is an encapsulated process that includes the required runtime dependencies for the program to run.
Registries are used to store container images to later share them in a controlled manner.
Containers are ephemeral by default, which means that the container engine removes the writable layer when you remove the container.
Hypervisors are applications that provide the virtualization functionality for virtual machines. The container equivalent of a hypervisor is a container engine, such as Podman.
Podman, which Red Hat Enterprise Linux provides, is a container engine that directly runs and manages container instances and container images on a single host.
With Podman, you can find, run, build, or deploy OCI (Open Container Initiative) containers and container images. By default, Podman is daemonless.
As a regular user, you can create systemd unit files to manage your rootless containers.
