The lxc driver is a new, experimental driver for installing Salt on
|

newly provisionned (via saltcloud) lxc containers. It will in turn use saltify to install
|

salt an rattach the lxc container as a new lxc minion.
|

As soon as we can, we manage baremetal operation over SSH.
|
||||
You can also destroy those containers via this driver.

===========================
|
||||
Getting Started With LXC
|
||||
===========================
|
||||
The LXC module is designed to install a LXC container Salt via a salt master on a
|
||||
controlled and possible remote minion.
|
||||
|
||||
In other words, we connect to a minion, then from that minion:
|
||||
- we provision and configure a container for networking access
|
||||
- We use saltify to deploy salt and rattach to master
|
||||
|
||||
Limitation
|
||||
------------
|
||||
- You can only act on one minion and one provider at a time.
|
||||
- Listing images must be targeted to a particular driver (nothing will be outputted with 'all')
|
||||
|
||||
Operation
|
||||
---------
|
||||
This do not use lxc.init to provide a more generic fashion to tie minions
|
||||
to their master (if any and defined) to allow custom association code.
|
||||
|
||||
Order of operation
|
||||
|
||||
- Spin up the lxc template container using salt.modules.lxc
|
||||
on desired minion (clone or template)
|
||||
- Change lxc config option if any to be changed
|
||||
- Start container
|
||||
- Change base passwords if any
|
||||
- Change base DNS base configuration if neccessary
|
||||
- Wait for lxc container to be up and ready for ssh
|
||||
- Test ssh connection and bailout in error
|
||||
- Via ssh (with the help of saltify, upload deploy script and seeds
|
||||
and reattach minion.
|
||||
|
||||
|
||||
Provider configuration

||||
----------------------
|

Here are the options to configure your containers
