It has been a while since I've been waiting for LXC to be stable enough to use in production. Let me tell you why I think that: LXD works like a daemon for LXC, it allows you to establish a communication handshake between your LXC client and any machine you have with LXD hosting several containers.

Lightweight and simple, just pop your command-line client and start creating, starting, stopping, cloning and snapshotting. Moving containers between LXD hosts is just as easy and performant. Here are the main LXD advantages:

• Secure by design (unprivileged containers, resource restrictions and much more)

• Scalable (from containers on your laptop to thousands of compute nodes)

• Intuitive (simple, clear API and crisp command line experience)

• Image-based (no more distribution templates, only good, trusted images)

If you’re using Ubuntu 16.04 LTS, start by:

$> sudo lxd init

$> sudo apt-get install lxd

This will install the LXD daemon, client tools and also LXC. LXD is not a replacement for LXC, it's just a daemon and a new set of client libraries and tools that allow you to manage remote servers hosting the containers.

Now you can create a new container:

$> lxc create odoo1

Or in a remote host:

$> lxc create host1:odoo1

List existing containers:

$> lxc list host1:

$> lxc exec host1:odoo1 bash

$> lxc --help

* config     - Manage configuration
* copy       - Copy containers within or in between lxd instances.
* delete     - Delete containers or container snapshots.
* exec       - Execute the specified command in a container.
* file       - Manage files on a container.
* help       - Presents details on how to use LXD.
* image      - Manipulate container images.
* info       - List information on LXD servers and containers.
* launch     - Launch a container from a particular image.
* list       - Lists the available resources.
* move       - Move containers within or in between lxd instances.
* profile    - Manage configuration profiles.
* publish    - Publish containers as images.
* remote     - Manage remote LXD servers.
* restart    - Changes state of one or more containers to restart.
* restore    - Set the current state of a resource back to a snapshot.
* snapshot   - Create a read-only snapshot of a container.
* start      - Changes state of one or more containers to start.
* stop       - Changes state of one or more containers to stop.
* version    - Prints the version number of this client tool.

For the remote host, you need to do the following to get access:

lxc config set core.https_address "[::]"lxc config set core.trust_password some-password

I hope this post gets you pumped enough for trying LXD, we sure love the concept and will be trying this "stable version" on test servers first ;)
