Questions tagged [lxd]

LXD is built around a very powerful, yet pretty simple, REST API. Under the hood, LXD uses LXC. If your question is about LXD, e.g.: is using the "lxc" command only available in LXD, you should use the tag LXD instead (or in addition) of LXC.

LXD is a next generation system container manager. It offers a user experience similar to virtual machines but using Linux containers instead.

It's image based with pre-made images available for a wide number of Linux distributions and is built around a very powerful, yet pretty simple, REST API.

Under the hood, LXD uses LXC through liblxc and its Go binding to create and manage the containers.

List snapshots of a lxd container

After creating a few snapshots in a lxd container using lxc snapshot I cannot find a way to list those snapshots. lxc list lists only containers, not the snapshots of each container. How can I list the names of all snapshots of a container? Thanks.
