LXD client inside docker

LXD
1

Hello,
Is it possible to run the LXD client inside docker container? I tried to use the ubuntu:focal container and install the lxd-client package in it, but when I try to run it I get information that lxd installation from snap is required.

root@1949b136e5a2:/# apt-get install lxd-client -y
...
root@1949b136e5a2:/# lxc ls

Command '/usr/bin/lxc' requires the lxd snap to be installed.
Please install it with:

snap install lxd

root@1949b136e5a2:/# snap install lxd
error: cannot communicate with server: Post http://localhost/v2/snaps/lxd: dial unix /run/snapd.socket: connect: no such file or directory

Is there any way to run the LXD client from docker? I need that for my pipeline.

Hi @Michal_Kzn,
AFAIK you cant, docker system do not support systemd and to install lxd easily you need snapd package which depends other system level packages. You can check that page for more detail, https://ubuntu.com/blog/lxd-vs-docker
Regards.

On windows and macos it is possible to compile only the lxd client (LXD client on Windows and macOS | Ubuntu). This is not possible in a docker container?

Humm, I see, Which linux distribution are you using?
Regards.

I’m trying to compile that in ubuntu focal container but without success.

@EDIT
After upgrade golang to latest version the build was successful :smiling_face_with_three_hearts:

go install github.com/lxc/lxd/lxc@latest

root@b0f5e1ca6b57:~# go/bin/lxc version
Client version: 5.7

Thanks for your help :slight_smile:

Marvelous, you are welcome. :smiling_face:
AFAIK, you need at least 1.18.X for golang.
Regards.
