meta-lxd (unofficial LXD layer for poky)

This layer provides support for building LXD and associated packages.

More information about LXD can be found at: https://github.com/lxc/lxd.

Disclaimer - This is unofficial! I am not associated with the LXD team.

The goal is to provide a simple recipe to allow Poky users to add LXD support to their images, since LXC only seems to be supported (through meta-virtualization) at the time of writing this document.

The testing so far has been limited to basic sanity checks of LXD functionality in a QEMU environment, your mileage may vary. If you encounter any problem, please submit an issue in this project.

Poky support is currently limited to the gatesgarth version, but this may evolve with future developments.

Dependencies

Getting started

You may start by adding the layer to your bblayers.conf file along with its dependencies:

BBLAYERS ?= " \
  [...] \
  /path/to/meta \
  /path/to/meta-poky \
  /path/to/meta-yocto-bsp \
  /path/to/meta-openembedded/meta-oe \
  /path/to/meta-openembedded/meta-python \
  /path/to/meta-openembedded/meta-filesystems \
  /path/to/meta-openembedded/meta-networking \
  /path/to/meta-openembedded/meta-perl \
  /path/to/meta-virtualization \
  /path/to/meta-security \
  /path/to/meta-lxd \
  [...] "

This will enable you to build the lxd recipe as well as an example image core-image-sato-lxd that corresponds to the standard core-image-sato with the lxd package added.

After installing the package, make sure to read the great LXD "Getting started guide": https://linuxcontainers.org/lxd/getting-started-cli/.

Adding the lxd package to your image

This can simply be achieved by adding the package to your image:

IMAGE_INSTALL += " lxd "

Building the example image

You may use bitbake to build this image:

bitbake core-image-sato-lxd

Runtime setup

The LXD daemon does not start automatically, so you first need to start it:

sudo -E PATH=$PATH LD_LIBRARY_PATH=$LD_LIBRARY_PATH /usr/bin/lxd --group sudo &

From there, you can setup LXD as you would normally do:

lxd init
