Juju-maas 环境搭建

可以查看此处代替本blog：（此处描述比较详细，但为全英文描述）

http://github.com/lenovo/workload-solution/wiki/Build-Juju-&-MAAS-on-KVM

以下操作均为root用户

install juju

ref：https://jujucharms.com/docs/stable/reference-install

on ubuntu 16.04

root@juju-KVM:~# snap install juju --classic

You can check which version of Juju you have installed with

root@juju-KVM:~# snap list juju

And update it if necessary with:

root@juju-KVM:~# snap refresh juju

Note: you can use the PPA for a stable deb package as well:

root@juju-KVM:~# add-apt-repository --update ppa:juju/stable
root@juju-KVM:~# apt install juju

.

.

install maas：

ref：https://docs.ubuntu.com/maas/2.1/en/installconfig-package-install

on ubuntu

查看依赖

root@maas-KVM:~# apt-cache search maas

The recommended way to set up an initial MAAS environment is to put everything on one machine:

root@maas-KVM:~# apt install -y maas

For a more distributed environment, the region controller can be placed on one machine:

root@maas-KVM:~# apt install maas-region-controller

and the rack controller on another:

root@maas-KVM:~# apt install maas-rack-controller
root@maas-KVM:~# maas-rack register

设置用户maas属性

sudo chsh -s /bin/bash maas
sudo su - maas
ssh-keygen -f ~/.ssh/id_rsa -N ''

创建UI用户：

root@maas-KVM:~# maas createadmin --username=admin --email=[e-mail]

其中，email实际上是没有用到的，但是不可以不写，执行后，会提示输入密码。

安装libvirt-bin

root@maas-KVM:~# apt-get install -y libvirt-bin

当选择KVM上的VM作为node时，需要安装libvirt-bin，否则会添加chassis不成功，或在添加完machine后会报如下错误。

Power control software for this power type is missing from the rack controller. To proceed, install the libvirt-bin package on the rack controller.

对于add chassis（KVM上的虚机），UI上地址（address）栏填写如下：

qemu+ssh://root@10.240.217.72/system

ref：https://docs.ubuntu.com/maas/2.1/en/nodes-add

测试：

virsh -c qemu+ssh://root@10.240.217.72/system list --all

.

将juju与maas结合起来

ref：https://jujucharms.com/docs/stable/clouds-maas

2.0version：
root@juju-KVM:~# cat maas-clouds.yaml
clouds:
    maas-cloud:
        type: maas
        auth-types: [oauth1]
        endpoint: http://192.168.100.4/MAAS

root@juju-KVM:~# juju add-cloud maas-cloud maas-clouds.yaml




2.2version：
root@juju-KVM:~# juju add-cloud
Cloud Types
  maas
  manual
  openstack
  oracle
  vsphere

Select cloud type: maas

Enter a name for your maas cloud: maas-cloud

Enter the API endpoint url: http://192.168.101.4:5240/MAAS 

也可以手动移除 cloud

juju remove-cloud maas-cloud

在juju上添加认证：

root@juju-KVM:~# juju add-credential maas-cloud
Enter credential name: maas-cloud-creds
Using auth-type "oauth1".
Enter maas-oauth:

该值可以从maas命令行获取

maas-region apikey --username=admin

或者从maas界面上获取。

点击maas界面右上角的已登录用户名，即可显示所需的keys

设置MAAS maas-region-controller

root@maas-KVM:~# dpkg-reconfigure maas-region-controller
    192.168.100.4    #(ip of maas)

设置完毕juju-maas之后在maas界面执行commission，获取机器硬件信息。 .

juju commands:

[cloud]
juju clouds
juju show-clouds testmaas


[controller]
juju bootstrap --bootstrap-series=centos7 --config bootstrap-timeout=900 maas-cloud maas-controller
juju bootstrap --config default-series=centos7 maas-cloud maas-controller
juju bootstrap --bootstrap-series=trusty maas-cloud maas-controller
juju bootstrap --bootstrap-series=xenial maas-cloud maas-controller
juju controllers
juju deploy $JUJU_REPOSITORY/trusty/vanilla --series xenial
juju destroy-controller maas-controller --destroy-all-models
juju switch maas-controller
juju gui --show-credentials


[machine]
juju machines
juju add-machine
juju remove-machine 4
