I'm trying to use cloud-init to control network configuration of a Lxd
container. Here's the config I use:
#cloud-config.yml
network:
version: 1
config:
- type: physical
name: eth0
subnets:
- type: static
ipv4: true
address: 10.10.10.20
netmask: 255.255.255.0
gateway: 10.10.10.1
control: auto
- type: nameserver
address: 10.10.10.1
I'm launching the container on Ubuntu 16.04 (v2.0.9) with the following:
lxc launch ubuntu: CONTAINER -c user.network-config="$(cat cloud-config.yml)"
In the container, cloud-init fail to apply the network configuration.
/var/lib/cloud/seed/nocloud-net/network-config : file created
/etc/network/interfaces.d/50-cloud-init.cfg : file not created
In cloud-init.log :
