TechnologyAPT Packages
The downloaded deb files should be under /var/cache/apt, use following command for copying to
another position:
$ find . | grep -i deb$ | xargs % cp % ~/Dest_Folder
$ scp -r ~/Dest_Folder Your_Cobbler_Machine
Repositories
Install dpkg-dev package, so we could generate the dpkg packages:
$ sudo apt-get install -y dpkg-dev
Create a new repository:
Edit the advanced options:

Now continue to modify the kickstart file for using the generated gpgs:
# pwd

# cp preseed_apt_repo_config preseed_apt_repo_config_pgpkey
The preseed_apt_repo_config_pgpkey should be listed as following:
# Additional repositories, local[0-9] available
#set $cur=1
#set $repo_data = $getVar("repo_data",[])
#for $repo in $repo_data

+++ # Add repo pgp pub key
+++ d-i apt-setup/local${cur}/key string \
+++ http://$http_server/cblr/repo_mirror/${repo.name}/public.pgp
#set $cur=$cur+1
#end for
#end for
Using the new preseed file, and changint the preseed_apt_repo_config_pgpkey:
# pwd
/var/lib/cobbler/kickstarts
# cp sample.seed ubuntu1604.seed
# vim ubuntu1604.seed
- $SNIPPET('preseed_apt_repo_config')
+ $SNIPPET('preseed_apt_repo_config_pgpkey')
Changing the seed in the cobbler_web:
Use cobbler sync for syncing the configuration.
Use the Repository
Add the ubuntu1604Mate into the Repos:
After added, the configuration should be:
Now cobbler sync for syncing the configuration.
Bug: you should move the preseed_apt_repo_config and then cobbler sync then your deployment will be OK:
$ mv /var/lib/cobbler/snippets/preseed_apt_repo_config /root/
$ cobbler sync
Added Mate Installation
Configure the preseed late:
# cp /var/lib/cobbler/scripts/preseed_late_default /var/lib/cobbler/scripts/preseed_late_default_mate
# vim /var/lib/cobbler/scripts/preseed_late_default_mate
# vim preseed_late_default_mate

TechnologyInstallation
Based on Ubuntu16.04, install maas via:
$ sudo apt-get install -y maas
After installation, create the default username/password via following command:
$ sudo maas-region createadmin --username=root --email=xxyy@xxyy.com
Password:
Again:
Now you could login to the http://YourIP/MAAS via:
Using API to talk
In maas cli, using following steps for generate the API key and use:
# sudo maas-region apikey --username=root
AYnuZY3gWTnpxJb7Kp:AtDG3yUmaDu8tXGzTc:tumR29xsRGL6A7T6M2G7LTETPP5kkDwC
# maas login mymaas http://10.17.17.2/MAAS/api/2.0
AYnuZY3gWTnpxJb7Kp:AtDG3yUmaDu8tXGzTc:tumR29xsRGL6A7T6M2G7LTETPP5kkDwC
You are now logged in to the MAAS server at
http://10.17.17.2/MAAS/api/2.0/ with the profile name 'mymaas'.
For help with the available commands, try:
maas mymaas --help
Later we will use mymaas for talk to MAAS Controller.
Add Boot Source
Click Images, you won’t see anything because the images are not downloaded. you could
download it manually via following command:
$ sudo apt-get install simplestreams ubuntu-cloudimage-keyring apache2
$ sudo sstream-mirror --keyring=/usr/share/keyrings/ubuntu-cloudimage-keyring.gpg \
https://images.maas.io/ephemeral-v2/daily/ /var/www/html/maas/images/ephemeral-v2/daily \
'arch=amd64' 'subarch~(generic|hwe-t)' 'release~(trusty|precise|xenial)' --max=1
After downloading, the image content will be available under /var/www/html/.
Or, if you downloaded the html files before, do following steps for using your
pre-downloaded packages:
$ tar xJvf html.tar.bz2 -C /var/www/html/
$ sudo maas mymaas boot-sources create url=http://10.17.17.2/mirror/images/ephemeral-v2/releases/ keyring_filename=/usr/share/keyrings/ubuntu-cloudimage-keyring.gpg
Now there are two boot-sources in maas, delete the default one(Because we are in china,
and its goddamned GFW!)
dash@maascontroller:~$ sudo maas mymaas boot-source delete 1
Success.
Machine-readable output follows:
dash@maascontroller:~$ sudo maas mymaas boot-sources read
Success.
Machine-readable output follows:
[
{
"keyring_data": "<memory at 0x7f4e9478b288>",
"resource_uri": "/MAAS/api/2.0/boot-sources/2/",
"id": 2,
"url": "http://10.17.17.2/mirror/images/ephemeral-v2/releases/",
"keyring_filename": "/usr/share/keyrings/ubuntu-cloudimage-keyring.gpg"
}
$
Import boot-sources via:
$ sudo maas mymaas boot-resources import
It will takes a little bit time for importing the boot images.

TechnologyPreparation
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

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.

TechnologyPackage Prepare
We have the default vagrant box generated by bento, listed it via:
➜ mesos vagrant box list | grep -i centos | grep -i virtualbox
centos72 (virtualbox, 0)
Now we want to generate a new box from it, and added our own configuration:
$ vagrant init centos72
$ vagrant up
$ vagrant ssh
Edit for keeping the cache:
$ cat /etc/yum.conf | more
[main]
cachedir=/home/vagrant/rpms/$basearch/$releasever
#keepcache=0
keepcache=1
Now poweroff the machine and export it to the new box:
$ vagrant package --output centoslocalrpm.box
$ vagrant box add centoslocalrpm centoslocalrpm.box
Using the new box, the rpm packages could be saved into the folder
/home/vagrant/rpms.
