[libvirt-users] Setting environment variables for LXC Containers



Hello

Is there a way to set custom environment variables for LXC containers so that it is available for all processes within the container?

The libvirt-lxc driver seems to be setting up only the below variables (as per the docs), but there doesn't seem to be a way customize it.
container
The fixed string libvirt-lxc to identify libvirt as the creator
container_uuid
The UUID assigned to the container by libvirt
PATH
The fixed string /bin:/usr/bin
TERM
The fixed string linux
HOME
The fixed string /

In addition to the standard variables, the following libvirt specific environment variables are also provided

LIBVIRT_LXC_NAME
The name assigned to the container by libvirt
LIBVIRT_LXC_UUID
The UUID assigned to the container by libvirt
LIBVIRT_LXC_CMDLINE
The unparsed command line arguments specified in the container configuration. Use of this is discouraged, in favour of passing arguments directly to the container init process via the initarg config element.


I am looking for something similar to this: https://linuxcontainers.org/lxc/manpages/man5/lxc.container.conf.5.html (lxc.environment)

Regards,
Harish
