You can use Podman modules to load a predetermined set of configurations. Podman modules are containers.conf files in the Tom’s Obvious Minimal Language (TOML) format.

These modules are located in the following directories, or their subdirectories:

• For rootless users: $HOME/.config/containers/containers.conf.modules
• For root users: /etc/containers/containers.conf.modules, or /usr/share/containers/containers.conf.modules

You can load the modules on-demand with the podman --module <your_module_name> command to override the system and user configuration files. While working with modules:

• You can specify modules multiple times by using the --module option.
• If <your_module_name> is the absolute path, the configuration file will be loaded directly.
• The relative paths are resolved relative to the three module directories mentioned previously.
• Modules in $HOME override those in the /etc/ and /usr/share/ directories.

For more information, see the containers.conf(5) man page on your system.
