| NAME | STATE | IPV4 | IPV6 | TYPE | SNAPSHOTS | To start your first container, try: lxc launch ubuntu:16.04 If this is your first time using LXD, you should also run: sudo lxd init LXD has been successfully lxd.lxc launch images:archlinux arch What IPv6 subnet should be used (CIDR notation, “auto” or “none”) ? What IPv4 subnet should be used (CIDR notation, “auto” or “none”) ? Would you like to create a new network bridge (yes/no) ? Would you like stale cached images to be updated automatically (yes/no) ? Would you like LXD to be available over the network (yes/no) ?
Would you like to have your containers share their parent's allocation (yes/no) ? In theory attack their parent container and gain more privileges than LXD can re-use your container's own allocation to avoid the problem.ĭoing so makes your nested containers slightly less safe as they could You will not have enough uid and gid to allocate to your containers. This means that unless you manually configured your host otherwise, We detected that you are running inside an unprivileged container. Name of the storage backend to use (dir or zfs) : The rest is business as usual for a LXD user: lxc exec lxd lxd init lxc exec lxd - apt remove -purge lxd lxd-client -yīecause we already have a stable LXD on the host, we’ll make things a bit more interesting by installing the latest build from git master rather than the latest stable release: lxc exec lxd - snap install lxd -edge Now lets clear the LXD that came pre-installed with the container so we can replace it by the snap. lxc launch ubuntu:16.10 lxd -c security.nesting=true This time with support for nested containers. Installing the LXD snap in a LXD containerįirst, lets get ourselves an Ubuntu 16.10 container with “squashfuse” installed inside it. Lxc exec nextcloud - apt install squashfuse -yĪnd then, lets install that “nextcloud” snap with: lxc exec nextcloud - snap install nextcloudįinally, grab the container’s IP and access “ with your web browser: lxc list nextcloud Ubuntu 16.10 container with “squashfuse” manually installed in itįirst, lets get ourselves an Ubuntu 16.10 container with “squashfuse” installed inside it.The easiest way to get this to work is with: The initial enablement was done on Ubuntu 16.10 with Ubuntu 16.10 containers, but all the needed bits are now progressively being pushed as updates to Ubuntu 16.04 LTS.
There are a lot of moving pieces to get all of this working. Snap packages are a new way of distributing software, directly from the upstream and with a number of security features wrapped around them so that these packages can’t interfere with each other or cause harm to your system. This support which finally landed in the latest Ubuntu kernels now makes it possible to install snap packages. The LXD and AppArmor teams have been working to support loading AppArmor policies inside LXD containers for a while.
