lxc profile create <profile>                   Create a profile.
lxc profile copy <profile> <remote>            Copy the profile to the specified remote.
lxc profile set <profile> <key> <value>        Set profile configuration.
lxc profile delete <profile>                   Delete a profile.
lxc profile edit <profile>                     
    Edit profile, either by launching external editor or reading STDIN.
    Example: lxc profile edit <profile> # launch editor
             cat profile.yml | lxc profile edit <profile> # read from profile.yml
lxc profile apply <container> <profiles>
    Apply a comma-separated list of profiles to a container, in order.
    All profiles passed in this call (and only those) will be applied
    to the specified container.
    Example: lxc profile apply foo default,bar # Apply default and bar
             lxc profile apply foo default # Only default is active
             lxc profile apply '' # no profiles are applied anymore
             lxc profile apply bar,default # Apply default second now

Devices:
lxc profile device list <profile>              List devices in the given profile.
lxc profile device show <profile>              Show full device details in the given profile.
lxc profile device remove <profile> <name>     Remove a device from a profile.
lxc profile device add <profile name> <device name> <device type> [key=value]...
    Add a profile device, such as a disk or a nic, to the containers
    using the specified profile.`)
