Hi all, I am trying to assign a public IP to one of my containers (all the others do not need static public IP with direct access to Internet as they are behind a proxy).
Am using Ubuntu 18.04. Here is my config and the command used to assign IP to the container.
On the host I have configured the second IP as it follows:
#HOST 01-netcfg.yaml
network:
version: 2
renderer: networkd
ethernets:
eth0:
match:
macaddress: 0a:00:00:00:00:00
addresses:
- 9x.xx.xxx.162/32
- 17x.xxx.xxx.186/24
#gateway6: fe80::1
routes:
- to: 0.0.0.0/0
via: 9x.xxx.xxx.xxx
#on-link: true
metric: 100
- to: 0.0.0.0/0
via: 17x.xxx.xxx.1
metric: 100
nameservers:
search: [ invalid ]
addresses:
- xx.xxx.xxx.252
- xx.xxx.xxx.251

I used the following command to assign public IP to mycont:
lxc config device add mycont eth0 nic nictype=ipvlan parent=eth0 ipv4.address=17x.xxx.xxx.186
Within the container (mycont) I have this:
$ ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
14: eth0@if2: <BROADCAST,MULTICAST,NOARP,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN group default qlen 1000
link/ether 00:50:56:3d:2a:a2 brd ff:ff:ff:ff:ff:ff
inet 17x.xxx.xxx.186/32 brd 255.255.255.255 scope global eth0
valid_lft forever preferred_lft forever
inet6 fe80::50:5600:13d:2aa2/64 scope link
valid_lft forever preferred_lft forever
However, since the configuration, “mycont” can’t access internet.
One more thing, mycont is not receiving IP from lxdbr0 as the other containers.
Will appreciate any help to fix this.
Thanks
