为什么要灰熊？为什么不？

一段时间以前，我创建了一个视频，展示了如何通过使用Hibernate节省EC2成本来轻松节省很多钱。Nutanix集群是唯一为想要提升和转移到公共云或为DR使用公共云的客户提供此产品的唯一一家供应商。我想共享代码段以及如何在群集门户中创建API用户。

您可以在这里首先熟悉Hibernate：

创建API用户来拨打电话：

  • 转到集群门户
  • 在组织下去用户
转到用户选项
  • 创建API用户
添加API用户

您可以将用户的范围限制为单个群集。

拥有API用户后，您可以使用以下脚本进行API调用或将脚本添加到VM。

＃！/usr/local/bin/python
导入哈希布
导入HMAC
导入时间
导入请求
导入基础64

＃客户凭证
来自群集门户的用户的#client_id
client_id =“ *********。img.frame.nutanix.com”
#client_secret密码来自群集门户上的用户
client_secret =“ vvvvvvvvf5ff3a3a3a3aeemmmhhhhhhhhhhhh1c302”
cluster_id =“ 1115AC9D-C768-5C71-8E-5FZZ7B535EC9”
＃创建签名
时间戳= int（time.time（））
to_sign =“％s％s”％（时间戳，client_id）
签名= hmac.new（client_secret，to_sign，hashlib.sha256）.hexdigest（）
#stage_domain =“ https://api-gateway-staging.staging.frame.nutanix.com/”
prod_domain =“ https://api-gateway-prod.frame.nutanix.com”
域= prod_domain

＃准备HTTP请求标头
标题= {“ x-frame-clientid”：client_id，“ x-frame-timestamp”：str（timestamp），“ x-frame-signature”：signature}

hibernate_req = requests.post（域 +“/v1/clusters/” + cluster_id +“/hibernate”，headers = headers）

Client_id和Client_secret将来自上述创建API用户的步骤。

一旦您进行了分类，我们就可以在Prism Central创建剧本。

为剧本挑选扳机

您可以基于事件/警报冬眠，也可以选择要运行的时间。在我的示例中，我将脚本放在VM上，然后调用脚本。

希望这使您的车轮转动，您可以提出自己的创意解决方案。

Awhile ago I created a video showing how you could easily save lots of money by saving dollars on the EC2 costs by using hibernate. Nutanix Clusters is the only on-prem vendor offering this\u00a0 for customers that want to lift and shift to the public cloud or use the public cloud for DR. I want to share the code snippet and how to create an API user in the Clusters portal.<\/p>

You can first get familiar with hibernate here:<\/p><\/oembed>

\u00a0<\/p>

\u00a0<\/p>

To create an API user to make the call:<\/p>

  • Go to the Clusters portal\u00a0<\/li>\t
  • Under Organization go to users<\/li><\/ul>
    \"//www.jhbzcj.com/next/hybrid-cloud-with-clusters-149/\"
    Go to the user option<\/figcaption><\/figure>
    • Create an API user<\/li><\/ul>
      \"//www.jhbzcj.com/next/hybrid-cloud-with-clusters-149/\"
      Add an API user<\/figcaption><\/figure>

      \u00a0 \u00a0You can limit the scope of the user to a single cluster.<\/p>

      \u00a0<\/p>

      Once you have a API user you can use the below script to make an API call or add a script to a VM.<\/p>

      #!\/usr\/local\/bin\/python
      import hashlib
      import hmac
      import time
      import requests
      import base64

      # Client credentials
      #client_id from the user from the clusters portal
      client_id = \"*********.img.frame.nutanix.com\" 
      #client_secret password from the user on the clusters portal
      client_secret = \"vvvvvvvf5ff3a3aemmmhhhh1c302\"
      cluster_id =\"1115ac9d-c768-5c71-8e8e-5fzz7b535ec9\"
      # Create signature
      timestamp = int(time.time())
      to_sign = \"%s%s\" % (timestamp, client_id)
      signature = hmac.new(client_secret, to_sign, hashlib.sha256).hexdigest()
      #stage_domain = \"https:\/\/api-gateway-staging.staging.frame.nutanix.com\/\"
      prod_domain = \"https:\/\/api-gateway-prod.frame.nutanix.com\"
      domain = prod_domain

      # Prepare http request headers
      headers = { \"X-Frame-ClientId\": client_id, \"X-Frame-Timestamp\": str(timestamp), \"X-Frame-Signature\": signature }

      hibernate_req = requests.post(domain + \"\/v1\/clusters\/\" + cluster_id + \"\/hibernate\"  , headers=headers)
      <\/code><\/pre>
      client_id and client_secret are going to come from the above step of creating an API user.<\/p>
      Once you have that sorted we can create a playbook in Prism Central.<\/p>
      \"//www.jhbzcj.com/next/hybrid-cloud-with-clusters-149/\"
      Picking your trigger for your playbook<\/figcaption><\/figure>
      \u00a0<\/p>
      You can hibernate based off an event\/alert or just pick a time that you want it to run. In my example I placed the script on a VM and then call the script.<\/p>

      Creating a playbook in Prism Central\u00a0<\/figcaption><\/figure>

      Hopefully this gets your wheels turning and you can come up with your own creative solutions.\u00a0<\/p>","quoteUsername":"dlink7","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

对于也希望通过Prism Centeral恢复集群的客户，简历API呼叫是

/API/REST/V1/CLUSTERS/{ID}/insume_cluster，因此请使用上面的相同调用，但用“ insume_cluster”替换hibnernate

For customer that are also looking to resume the cluster via Prism Centeral the Resume API call is\u00a0<\/p>

\/api\/rest\/v1\/clusters\/{id}\/resume_cluster , so use the same call above but replace hibnernate with \u201cresume_cluster\u201d<\/p>","quoteUsername":"dlink7","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">
