NAME

libpod.conf - libpod configuration file

DESCRIPTION

The libpod.conf file is the default configuration file for all tools using libpod to manage containers.

OPTIONS

image_default_transport="" Default transport method for pulling and pushing images

runtime_path="" Paths to search for a valid OCI runtime binary

conmon_path="" Paths to search for the Conmon container manager binary

conmon_env_vars="" Environment variables to pass into Conmon

cgroup_manager="" Specify the CGroup Manager to use; valid values are "systemd" and "cgroupfs"

init_path="" Path to the container-init binary, which forwards signals and reaps processes within containers. Note that the container-init binary will only be used when the --init for podman-create and podman-run is set.

hooks_dir=["path", ...]

Each *.json file in the path configures a hook for Podman containers. For more details on the syntax of the JSON files and the semantics of hook injection, see oci-hooks(5). Podman and libpod currently support both the 1.0.0 and 0.1.0 hook schemas, although the 0.1.0 schema is deprecated.

Paths listed later in the array higher precedence (oci-hooks(5) discusses directory precedence).

For the annotation conditions, libpod uses any annotations set in the generated OCI configuration.

For the bind-mount conditions, only mounts explicitly requested by the caller via --volume are considered. Bind mounts that libpod inserts by default (e.g. /dev/shm) are not considered.

If hooks_dir is unset for root callers, Podman and libpod will currently default to /usr/share/containers/oci/hooks.d and /etc/containers/oci/hooks.d in order of increasing precedence. Using these defaults is deprecated, and callers should migrate to explicitly setting hooks_dir.

static_dir="" Directory for persistent libpod files (database, etc) By default this will be configured relative to where containers/storage stores containers

tmp_dir="" Directory for temporary files Must be a tmpfs (wiped after reboot)

max_log_size="" Maximum size of log files (in bytes)

no_pivot_root="" Whether to use chroot instead of pivot_root in the runtime

cni_config_dir="" Directory containing CNI plugin configuration files

cni_plugin_dir="" Directories where CNI plugin binaries may be located

pause_image = "" Pause container image name for pod pause containers. When running a pod, we start a pause processes in a container to hold open the namespaces associated with the pod. This container and process, basically sleep/pause for the lifetime of the pod.

pause_command="" Command to run the pause container

namespace="" Default libpod namespace. If libpod is joined to a namespace, it will see only containers and pods that were created in the same namespace, and will create new containers and pods in that namespace. The default namespace is "", which corresponds to no namespace. When no namespace is set, all containers and pods are visible.

label="true|false" Indicates whether the containers should use label separation.

FILES

/usr/share/containers/libpod.conf, default libpod configuration path

/etc/containers/libpod.conf, override libpod configuration path
