juju attach unnecessary interfaces to lxd container

[Vladimir Burlakov]

Hello everyone!
I try to deploy an application to lxd container on manually attached machine (ubuntu-xenial)
and container do not start, with the error - «Missing parent 'docker_gwbridge’ for nic ‘eth2’».
I see in the logs, that juju tries to add docker interfaces to the container, though on a target
machine default lxd profile has no such interfaces.. I wonder, if someone can help me to fix
the issue?

-
$ juju --version:
2.2.6-xenial-amd64

-
yaml file of the application, that i trying to deploy:
$ cat keystone.yaml
keystone:
admin-password: openstack
openstack-origin: 'cloud:xenial-pike'
worker-multiplier: 0.25

-
Default profile on a target machine:
—
### Note that the name is shown but cannot be changed
config: {}
description: Default LXD profile
devices:
eth0:
name: eth0
nictype: bridged
parent: br0
type: nic
