Here is a relevant GitHub issue that might contain useful information.ДЇor anybody who is still struggling how to assign static ip adresses to the lxd containers.

Unfortunately, I cannot remember where I first found this solution. This webpage contains information on the CIDR notation. Take a look here for the acceptable configuration keys appendable to lxc.net. As a result, the container entry in lxc list might contain several IP addresses. Note that this will probably not change the current IP address of the container (in my setup anyway) the container should be reachable at both its original IP and the newly assigned IP. You will probably need to restart the container after executing the command. Where, , and are the container name, network interface number, desired static ip address, and the CIDR for the desired subnet mask, respectively.ДЇor instance, if you want to assign 240.10.0.20 with subnet mask 255.255.255.0 to the 0'th network interface of the container named hello, you can use: lxc config set hello raw.lxc 'lxc.net.0.ipv4.address = 240.10.0.20/24' System info: lxc-3.0.1 on Ubuntu Server 18.04.1.ДЄfter a lot of searching, I found this simple command to assign a static ip to a container: lxc config set raw.lxc ' = /' auto is only available when using the veth and macvlan network types. Can also have the special value auto, which means to take the primary address from the bridge interface (as specified by the option) and use that as the gateway. Specify the ipv4 address to use as the gateway inside the container. The broadcast address should be specified on the same line, right after the ipv4 address. Several lines specify several ipv4 addresses. Specify the ipv4 address to assign to the virtualized interface.

The interface mac address is dynamically allocated by default to the virtual interface, but in some cases, this is needed to resolve a mac address conflict or to always have the same link-local ipv6 address eth0, this option will rename the interface in the container. The interface name is dynamically allocated, but if another name is needed because the configuration files being used by the container use a generic name, eg. The part most relevant to your question is the following: Sensible values are automatically produced for unspecified variables. Under network, you will find all you need. They pertain to different areas, hostname, network, console, ttys, mount point, cgroups, capabilities. The possible values of the parameters are specified in the Manual.

These configurations are to be placed in the file /var/lib/lxc/ContainerName/config.

What is the right way of doing this (I mean, the latest Docker has an -ip switch in docker run which sets the IP address) ?.

Only upon rebooting the container, the host seem to have forgotten my static IP, and takes the one from DHCP. In which you can put a (what looks like) static IP4-address. I found (with help of Google and locate) a control file: > locate lxc.conf Only I don't seem to have any control over the IP address here. | NAME | STATE | IPV4 | IPV6 | TYPE | SNAPSHOTS | After installing LXD I created my own container: > lxc launch images:centos/7/amd64 thing Creating thing So I turned to LXC/LXD containers, which is great. I have done some Docker testing over the years, but for a specific kind of testing, I need a little more then just application containers.
