I set static IP for my LXD containers by configuring each container's
/etc/network/interfaces.d/50-cloud-init.cfg:

  auto lo
  iface lo inet loopback
  
  auto eth0
  iface eth0 inet static
address 10.x.x.x
netmask 255.255.255.0
network 10.x.x.x
broadcast 10.x.x.x
gateway 10.x.x.x
dns-nameservers 10.x.x.x
dns-search xxx.xxx

HTH.

Yes. You should delete it. Everything must be under br1.

if you use macvlan, there is no bridge anymore.

On the host, if I assign the host ip configuration to br1, don't I need
to change something about the eno1 configuration?

macvlan does not require router support. I use it everyday.

Re: [lxc-users] LXC containers w/ static IPs work on some hosts, not on others

[Marat Khalili]

Hello,

I use lxc (not lxd!) with static IP addresses. Here's my config (Ubuntu 
16.04):


/etc/network/interfaces:


auto br1
iface br1 inet static
bridge_ports eno1
bridge_fd 0
address 10... # host ip configuration follows

/etc/lxc/default.conf:

lxc.network.type = veth
lxc.network.link = br1
lxc.network.flags = up
lxc.network.hwaddr = 00:16:3e:xx:xx:xx

/var/lib/lxc/test/rootfs/etc/network/interfaces:

auto eth0
iface eth0 inet static
address 10... #container ip configuration follows


You seem to use macvlan. It is explicitly designed to prevent containers 
from talking to each other (they can only talk via external router), and 
it complicates things, e.g. requires router support (which might be a 
problem in your case). Unless you specifically need this feature you may 
have better results (and performance) with bridge like above.


Unfortunately, many places on the web teach people to configure macvlan 
with containers without really explaining why.

Re: [lxc-users] LXC containers w/ static IPs work on some hosts, not on others

[McDonagh, Ed]

Yes, the naming convention they have chosen makes looking for lxd information 
very difficult when the commands, file paths and conventions are different to 
the lxc predecessor/underlying programs.

But I think that has been discussed on this list before!

I started out with lxd but ran into problems when I tried googling for 
instructions on how to assign a static IP address to a container.  All of the 
instructions I found said to edit /var/lib/lxc//config, and there 
was no /var/lib/lxc/ directory.  So I uninstalled lxd and installed lxc instead.

There is no lxc-profile command, and lxc-ls and lxc-info don't list anything 
about a profile.  I have no idea if that means anything.

Re: [lxc-users] LXC containers w/ static IPs work on some hosts, not on others

[McDonagh, Ed]

I’m very much not a guru on this topic, but it strikes me to check if you are 
using lxc for a reason, rather than using lxd?

If you don’t have a legacy reason, I don’t know why you wouldn’t want to use 
the new tools that are being developed.

There is no lxc-profile command, and lxc-ls and lxc-info don't list anything 
about a profile.  I have no idea if that means anything.

[lxc-users] LXC containers w/ static IPs work on some hosts, not on others

[Michael Peek]

Hi gurus,

I'm scratching my head again.  I'm using the following commands to
create an LXC container with a static IP address:

# lxc-create -n my-container-1 -t download -- -d ubuntu -r xenial -a
amd64

# vi /var/lib/lxc/my-container-1/config

Change:
# Network configuration
# lxc.network.type = veth
# lxc.network.link = lxcbr0
# lxc.network.flags = up
# lxc.network.hwaddr = 00:16:3e:0d:ec:13
lxc.network.type = macvlan
lxc.network.link = eno1

# vi /var/lib/lxc/my-container-1/rootfs/etc/network/interfaces

Change:
#iface eth0 inet dhcp
iface eth0 inet static
  address xxx.xxx.xxx.4
  netmask 255.255.255.0
  network xxx.xxx.xxx.0
  broadcast xxx.xxx.xxx.255
  gateway xxx.xxx.xxx.1
  dns-nameservers xxx.xxx.0.66 xxx.xxx.128.66 8.8.8.8
  dns-search my.domain

# lxc-start -n my-container-1 -d


It failed to work.  I reviewed my notes from past posts to the list but
found no discrepancies.  So I deleted the container and tried it on
another host -- and it worked.  Next I deleted that container and went
back to the first host, and it failed.  Lastly, I tried the above steps
on multiple hosts and found that it works fine on some hosts, but not on
others, and I have no idea why.  On hosts where this fails there are no
error messages, but the container can't access the network, and nothing
on the network can access the container.

Is there some step that I'm missing?

Thanks for any help,

Michael Peek
