Setup LXD On Ubuntu1604

TurnToJPG -->

Preparation

By default the lxd is installed in ubuntu1604.

Image

The image file are downloaded before we actually install it, install the image via:

$ lxc image import ubuntu-16.04-server-cloudimg-amd64-lxd.tar.xz ubuntu-16.04-server-cloudimg-amd64-root.tar.xz --alias ubuntu1604
$ lxc image list

Start Container

Start the container via:

$ lxc launch ubuntu1604 first1404
$ lxc list
+------------+---------+------+------+------------+-----------+
|    NAME    |  STATE  | IPV4 | IPV6 |    TYPE    | SNAPSHOTS |
+------------+---------+------+------+------------+-----------+
| first1404  | RUNNING |      |      | PERSISTENT | 0         |
+------------+---------+------+------+------------+-----------+

Attach to the running container via:

$ lxc exec first1404 /bin/bash

In this container you could do anything, for your customization of the container.

More Images

After your modification is done, shutdown the running container, and submit your modification to a new container:

$ lxc publish second1604 --alias my-new-image
$ lxc image list
+--------------+--------------+--------+--------------------------------------+--------+----------+------------------------------+
|    ALIAS     | FINGERPRINT  | PUBLIC |             DESCRIPTION              |  ARCH  |   SIZE   |         UPLOAD DATE          |

Container Networking

The default networking is a seperated network, but we could set the lxd using the hosted network, via following steps:

$ cat /etc/network/interfaces

auto ens3
iface ens3 inet manual

auto containerbr 
iface containerbr inet static
address 192.168.10.193
netmask 255.255.0.0
gateway 192.168.0.176
dns-nameservers 180.76.76.76
bridge_ports ens3

Reboot the machine, you have the running bridge containerbr, now you could set your bridge to this newly created bridge:

$ lxc profile device set default eth0 parent containerbr

Via this you cuold set the same subnet networking address just as in containerbr.
