Container Support

Fedora IoT has excellent support for container-focused workflows. Containers provide for separation of OS updates from application updates, as well as allow testing and deployment of different versions of applications. Fedora IoT uses podman, a daemonless container engine to develop, download, manage, and run containers to support your home assistant, industrial gateways, or data storage and analytics.

With podman, images and containers can be managed and used by a non-privileged user. Commands are very similar to those used with docker.

Show the version of podman and other configuration settings:

Run as a user, the storage location is under the ~/.local/share/containers directory. You can customize podman with files in the ~/.config/containers directory.

Run as root, the storage location is defined in the '/etc/containers/storage.conf' file and defaults to '/var/run/containers/storage'.

Any of the podman commands have help available for several levels of commands.
