问题描述
也许我的问题没有道理，但这就是我想要做的:
Maybe my question does not make sense, but this is what I'm trying to do:
- 我有一个正在运行的Kubernetes集群，该集群在裸机上的CoreOS上运行.
- 我正在尝试使用Cinder从OpenStack云提供商挂载块存储.
根据我的阅读，要能够连接到块存储提供程序，我需要将kubelet配置为cloud-provider=openstack，并使用cloud.conf文件进行凭据配置.
From my readings, to be able to connect to the block storage provider, I need kubelet to be configured with cloud-provider=openstack, and use a cloud.conf file for the configuration of credentials.
我这样做了，并且auth部分似乎工作正常(即我已成功连接到云提供程序)，但是kubelet然后抱怨说它无法在openstack提供程序上找到我的节点.
I did that and the auth part seems to work fine (i.e. I successfully connect to the cloud provider), however kubelet then complains that it cannot find my node on the openstack provider.
我得到:
Unable to construct api.Node object for kubelet: failed to get external ID from cloud provider: Failed to find object
这类似于以下问题:
无法为kubelet构造api.Node对象:无法从云提供商获取外部ID:无法找到对象
但是，我知道kubelet不会在OpenStack提供程序上找到我的节点，因为它不在此处托管！该错误是有道理的，但是我该如何避免呢?
However, I know kubelet will not find my node at the OpenStack provider since it is not hosted there! The error makes sense, but how do I avoid it?
简而言之，我该如何告诉kubelet不要在那儿寻找我的节点，因为我只需要它来查找要安装的存储块?
In short, how do I tell kubelet not to look for my node there, as I only need it to look up the storage block to mount it?
是否甚至可以这种方式挂载块存储?我误会了它的工作原理吗?
Is it even possible to mount block storage this way? Am I misunderstanding how this works?
推荐答案
似乎有将Cinder存储连接到裸机的新方法，但显然只是PoC
There seem to be new ways to attach Cinder storage to bare metal, but it's apparently just PoC
