Containers provide a lightweight way to distribute and run an application with its dependencies so that it does not conflict with installed software on the host.
Containers run from container images that you can download from a container registry or create yourself.
You can use container files with instructions to build a customized container image.
Podman, which Red Hat Enterprise Linux provides, directly runs and manages containers and container images on a single host.
Containers can be run as root, or as non-privileged rootless containers for increased security.
You can map network ports on the container host to pass traffic to services that run in its containers.
You can use environment variables to configure the software in containers at build time.
Although container storage is temporary, you can attach persistent storage to a container by using the contents of a directory on the container host, for example.
You can configure a systemd unit file to automatically run containers when the system starts.
