salt-cloud也是基於openstack來做的，它可以支持多種雲的使用。比如：Aliyun、Azure、DigitalOcean、EC2、Google Compute Engine、HP Cloud、OpenStack、等等
安裝相關組件和依賴包
[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 # 註意這裏的類型可以通過openstack endpoint list 查看到# Configure Openstack authentication credentials # user: demo password: demo # tenant is the project name tenant: demo # 項目名稱 provider: openstack # skip SSL certificate validation (default false) insecure: false
配置saltstack
[root@linux-node1 cloud.providers.d]#systemctl start salt-master [root@linux-node1 cloud.providers.d]# vim /etc/salt/minion master: 192.168.56.12 [root@linux-node1 cloud.providers.d]# systemctl start salt-minion [root@linux-node1 cloud.providers.d]# salt-key Accepted Keys: Denied Keys: Unaccepted Keys: linux-node1.oldboyedu.com Rejected Keys: [root@linux-node1 cloud.providers.d]# salt-key -A The following keys are going to be accepted: Unaccepted Keys: linux-node1.oldboyedu.com Proceed? [n/Y] y Key for minion linux-node1.oldboyedu.com accepted.
[root@linux-node1 cloud.providers.d]# salt ‘*‘ test.ping
linux-node1.oldboyedu.com:

使用salt-cloud創建openstack虛擬機
眾所周知，saltstack有三大功能：遠程執行、配置管理、雲管理。其中的雲管理就是通過salt-cloud完成的。salt-cloud能夠管理很多雲環境（公有雲、私有雲），連大名鼎鼎的阿裏雲也可以通過salt-cloud來創建虛擬機哦。
本次主要講解使用salt-cloud管理openstack（L版）私有雲來創建虛擬機。（前提openstack環境運行正常，能正常創建虛擬機）
1、 安裝saltstack
yum install salt-master salt-minion salt-cloud -y
安裝依賴包：
yum install python-libcloud -y
2、 創建provider配置文件，告訴salt-cloud如何連接openstack（yaml語法，註意空格）
[root@linux-node1 cloud.providers.d]# pwd /etc/salt/cloud.providers.d [root@linux-node1 cloud.providers.d]# vim openstack.conf myopenstack: # 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 # Configure Openstack authentication credentials # user: demo password: demo # tenant is the project name tenant: demo provider: openstack # skip SSL certificate validation (default false) insecure: false
3 、檢查配置：
語法：
salt-cloud --list-locations <provider_name> 查看可用的區域
salt-cloud --list-p_w_picpaths <provider_name> 查看可用的鏡像
salt-cloud --list-sizes <provider_name> 查看可用的虛擬機大小
例：查看可用的鏡像
salt-cloud --list-p_w_picpaths myopenstack -l debug
myopenstack：provider配置文件中定義的ID
-l debug ：開啟debug模式，方便定位和調試故障。
[root@linux-node1 ~]# salt-cloud --list-p_w_picpaths myopenstack -l debug [DEBUG ] Reading configuration from /etc/salt/cloud [DEBUG ] Reading configuration from /etc/salt/master [DEBUG ] Using cached minion ID from /etc/salt/minion_id: linux-node1.example.com [DEBUG ] Missing configuration file: /etc/salt/cloud.providers [DEBUG ] Including configuration from ‘/etc/salt/cloud.providers.d/openstack.conf‘ [DEBUG ] Reading configuration from /etc/salt/cloud.providers.d/openstack.conf [DEBUG ] Missing configuration file: /etc/salt/cloud.profiles [DEBUG ] Configuration file path: /etc/salt/cloud [WARNING ] Insecure logging configuration detected! Sensitive data may be logged.

The preferable way to get client class or object you can find in novaclient.client module. warnings.warn("Module novaclient.v1_1 is deprecated (taken as a basis for " [DEBUG ] Could not LazyLoad parallels.avail_sizes [DEBUG ] LazyLoaded parallels.avail_locations [DEBUG ] LazyLoaded proxmox.avail_sizes [DEBUG ] Could not LazyLoad saltify.destroy [DEBUG ] Could not LazyLoad saltify.avail_sizes [DEBUG ] Could not LazyLoad saltify.avail_p_w_picpaths [DEBUG ] Could not LazyLoad saltify.avail_locations [DEBUG ] LazyLoaded rackspace.reboot [DEBUG ] Could not LazyLoad openstack.list_locations [DEBUG ] LazyLoaded rackspace.list_locations [DEBUG ] OpenStack authenticating using password [DEBUG ] LazyLoaded nested.output myopenstack: ---------- openstack: ---------- cirros: ---------- driver: extra: ---------- created: 2015-12-13T14:24:05Z metadata: ---------- minDisk: 0 minRam: 0 progress: 100 serverId: None status: ACTIVE updated: 2015-12-13T14:24:05Z get_uuid: id: c503fb83-7d52-40e9-b1cc-4773e650986e name: cirros uuid: 2986f30365f55599f838f656a51acdaec1fa81a2 new: ---------- driver: extra: ---------- created: 2015-12-25T09:17:50Z metadata: ---------- minDisk: 0 minRam: 0 progress: 100 serverId: None status: ACTIVE updated: 2015-12-25T09:17:57Z get_uuid: id: fdd664b3-ebf2-4904-815f-0d1cdf9955d4 name: new uuid: 9f4f8a437ebc8123c1a8725156ee91566928d9f0
可以看到，當前有兩個可用的鏡像，cirros 和new ，並且可以看到更過鏡像的信息。
4、 編寫profile配置文件，告訴salt-cloud創建虛擬機的細節，後期創建虛擬機時只需要調用該名字即可。
[root@linux-node1 cloud.profiles.d]# vim openstack_web.conf web-node: provider: myopenstack size: m1.tiny p_w_picpath: new ssh_key_file: /root/.ssh/id_rsa ssh_key_name: mykey ssh_interface: private_ips networks: - fixed: - 2c4c9edc-dbb8-467c-bc67-a2c6ff23d885 minion: master: 192.168.56.11 grains: role: webserver
5 、創建虛擬機
[root@linux-node1 cloud.profiles.d]# salt-cloud -p web-node test -l debug
-p 指定profile中虛擬機ID名稱
6 、查看驗證：
[root@linux-node1 ~]# nova list --------------------+------+--------+------------+-------------+---------------------+ | ID | Name | Status | Task State | Power State | Networks | +-------------------+------+--------+------------+-------------+---------------------+ | b4035529-6cd7-4b9b-a6e9-c63d5bfb2d4b | test | ACTIVE | - | Running | flat=192.168.56.118 | +-------------------+------+--------+------------+-------------+---------------------+
通過上面的配置文件，salt-cloud不僅能夠創建虛擬機，還能夠在虛擬機裏安裝salt-minion，
並自動添加到salt-master認證裏面去（還設置了一個grains哦，很方便吧）
