我是使用 cloudify 的新手。我已经成功地在 aws ec2 上引导了一个 Cloudify 管理器。但是，我在执行 nodecellar 的安装工作流时遇到了问题。
我的环境是：cloudify-windows-cli_3.2.1、cloudify-manager-blueprints 3.2、cloudify-nodecellar-example 3.2
输入.yaml
image: 'ami-5189a661'
size: 't2.medium'
agent_user: 'ubuntu'
在执行安装工作流时，nodecellar 和 mongodb 的实例已经成功创建，但是出现了一些错误：
Executing workflow 'install' on deployment 'nodecellar' at management server 52.
19.100.72 [timeout=900 seconds]
Deployment environment creation is in progress!
Waiting for create_deployment_environment workflow execution to finish...
