# command-line options/flags for container engine tools like Podman & Buildah,

# but in a TOML format that can be easily modified and versioned.

# Please refer to containers.conf(5) for details of all configuration options.

# Not all container engines implement all of the options.

# All of the options have hard coded defaults and these options will override

# the built in defaults. Users can then override these options via the command

# line. Container engines will read containers.conf files in up to three

#  2. /etc/containers/containers.conf

#  3. $HOME/.config/containers/containers.conf (Rootless containers ONLY)

#  Items specified in the latter containers.conf, if they exist, override the

# previous containers.conf settings, or the default settings.
