使用salt-cloud创建openstack虚拟机

salt-cloud也是基于openstack来做的，它可以支持多种云的使用。比如：Aliyun、Azure、DigitalOcean、EC2、Google Compute Engine、HP Cloud、OpenStack、等等

安装相关组件和依赖包

[root@linux-node1 ~]# yum -y install salt-master salt-minion salt-cloud python-libcloud

修改配置文件

[root@linux-node1 ~]# cd /etc/salt/cloud.providers.d/
[root@linux-node1 cloud.providers.d]# cat openstack.conf 
my-openstack-config:
  # Set the location of the salt-master
  #
  minion:
    master: 192.168.56.11

  # Configure the OpenStack driver
  #
  identity_url: http://192.168.56.11:5000/v2.0/tokens
  compute_name: nova
  protocol: ipv4

  compute_region: RegionOne
  # 注意这里的类型可以通过openstack endpoint list 查看到

  # Configure Openstack authentication credentials
  #
  user: demo
  password: demo
  # tenant is the project name
  tenant: demo
  # 项目名称

  provider: openstack

  # skip SSL certificate validation (default false)
  insecure: false

使用salt-cloud创建openstack虚拟机

众所周知，saltstack有三大功能：远程执行、配置管理、云管理。其中的云管理就是通过salt-cloud完成的。salt-cloud能够管理很多云环境（公有云、私有云），连大名鼎鼎的阿里云也可以通过salt-cloud来创建虚拟机哦。

本次主要讲解使用salt-cloud管理openstack（L版）私有云来创建虚拟机。（前提openstack环境运行正常，能正常创建虚拟机）

1、安装saltstack

安装依赖包：

2、创建provider配置文件，告诉salt-cloud如何连接openstack（yaml语法，注意空格）

3 、检查配置：

语法：

salt-cloud --list-locations <provider_name> 查看可用的区域

salt-cloud --list-p_w_picpaths <provider_name> 查看可用的镜像

salt-cloud --list-sizes <provider_name> 查看可用的虚拟机大小

例：查看可用的镜像

myopenstack：provider配置文件中定义的ID

-l debug ：开启debug模式，方便定位和调试故障。

[root@linux-node1 ~]# salt-cloud --list-p_w_picpaths myopenstack -l debug

                9f4f8a437ebc8123c1a8725156ee91566928d9f0

可以看到，当前有两个可用的镜像，cirros 和new ，并且可以看到更过镜像的信息。

4、编写profile配置文件，告诉salt-cloud创建虚拟机的细节，后期创建虚拟机时只需要调用该名字即可。

6 、查看验证：

通过上面的配置文件，salt-cloud不仅能够创建虚拟机，还能够在虚拟机里安装salt-minion，

并自动添加到salt-master认证里面去（还设置了一个grains哦，很方便吧）

官方手册： https://docs.saltstack.com/en/latest/topics/cloud/openstack.html

安装环境：
172.16.1.211 salt-master服务器
172.16.1.240 openstack控制节点

ps: 下面都在salt-master操作

1.安装插件：

yum install salt-cloud python-libcloud

2.创建salt-cloud配置文件：

mkdir /etc/salt/cloud.providers.d/ 
vim /etc/salt/cloud.providers.d/openstack.conf
my-openstack-config:

  minion:
    master: 172.16.1.211

  identity_url: http://172.16.1.240:5000/v2.0/tokens
  compute_name: nova
  protocol: ipv4

  compute_region: RegionOne

  user: demo
  password: demo

  tenant: demo

  driver: openstack
  provider: openstack

  insecure: false

3.查看镜像列表：

salt-cloud --list-images openstack  #查看镜像列表
salt-cloud --list-size openstack    #查看云主机类型

4.创建Salt-cloud虚拟机模板文件：

vim /etc/salt/cloud.profiles.d/web.conf
web-node:                                     #虚拟机模板名称
  provider: my-openstack-config               #前面配置文件定义的
  size: m1.tiny                               #云主机类型
  image: cirros                               #镜像名称
  ssh_key_file: /root/.ssh/id_rsa             #公钥文件
  ssh_key_name: mykey                         #密钥对名称
  ssh_interface: private_ips
  networks:
    - fixed:
      - 69200e49-0f8b-47b6-9bb5-2db9bca9a393  #网络的ID
  minion:                                     #下面是自动给虚拟机安装salt-minion并配置
    master: 172.16.1.211
    grains:
      role: webserver-01

4.通过Salt-cloud创建Openstack虚拟机：

salt-cloud -p web-node web-test1 -l debug

# -p: 虚拟机模板名称
# web-test1: 创建虚拟机的名称
# -l debug： 打印debug
