Copy a stopped container.

Parameters

c Original container.

newname New name for the container. If NULL, the same name is used and a new lxcpath MUST be specified.

lxcpath lxcpath in which to create the new container. If NULL, the original container's lxcpath will be used.

flags Additional LXC_CLONE* flags to change the cloning behaviour:

bdevtype Optionally force the cloned bdevtype to a specified plugin. By default the original is used (subject to snapshot requirements).

bdevdata Information about how to create the new storage (i.e. fstype and fsdata).

newsize In case of a block device backing store, an optional size. If 0, the original backing store's size will be used if possible. Note this only applies to the rootfs. For any other filesystems, the original size will be duplicated.

hookargs Additional arguments to pass to the clone hook script.

Returns

Newly-allocated copy of container c, or NULL on error.

note: If devtype was not specified, and flags contains LXC_CLONE_SNAPSHOT then use the native bdevtype if possible, else use an overlayfs.

snapshot: unsafe extern "C" fn(c: *mut lxc_container, commentfile: *const c_char) -> c_int

Create a container snapshot.

Assuming default paths, snapshots will be created as /var/lib/lxc/<c>/snaps/snap<n> where <c> represents the container name and <n> represents the zero-based snapshot number.

Parameters

c Container.

commentfile Full path to file containing a description of the snapshot.

Returns

-1 on error, or zero-based snapshot number.

note: commentfile may be NULL but this is discouraged.

version: 1.0.0

snapshot_list: unsafe extern "C" fn(c: *mut lxc_container, snapshots: *mut *mut lxc_snapshot) -> c_int

Obtain a list of container snapshots.

Parameters

c Container.

snapshots Dynamically-allocated Array of lxc_snapshot's.

Returns

Number of snapshots.

note: The array returned in snapshots is allocated, so the caller must free it.

note: To free an individual snapshot as returned in \p snapshots, call the snapshots free function (see src/tests/snapshot.c for an example).

version: 1.0.0

snapshot_restore: unsafe extern "C" fn(c: *mut lxc_container, snapname: *const c_char, newname: *const c_char) -> bool

Parameters

c Container.

snapname Name of snapshot.

newname Name to be used for the restored snapshot.

Returns

true on success, else false.

warning: If newname is the same as the current container name, the container will be destroyed. However, this will fail if the snapshot is overlay-based, since the snapshots will pin the original container.

note: As an example, if the container exists as /var/lib/lxc/c1, snapname might be 'snap0' (representing /var/lib/lxcsnaps/c1/snap0). If newname is c2, then snap0 will be copied to /var/lib/lxc/c2.
