我在kops配置的AWS集群上测试了kubernetes部署和EBS卷安装 . 这是部署yml文件:
apiVersion: extensions/v1beta1
kind: Deployment
metadata:
name: helloworld-deployment-volume
spec:
replicas: 1
template:
metadata:
labels:
app: helloworld
spec:
containers:
- name: k8s-demo
image: wardviaene/k8s-demo
ports:
- name: nodejs-port
containerPort: 3000
volumeMounts:
- mountPath: /myvol
name: myvolume
volumes:
- name: myvolume
awsElasticBlockStore:
volumeID: <volume_id>
在 kubectl create -f <path_to_this_yml>
之后,我在pod描述中收到以下消息:
Attach failed for volume "myvolume" : Error attaching EBS volume "XXX" to instance "YYY": "UnauthorizedOperation: You are not authorized to perform this operation. status code: 403
看起来这只是一个权限问题 . 好的,我检查了节点角色 IAM
- > Roles
- > nodes.<my_domain>
的策略,发现没有允许操作卷的操作,默认情况下只有 ec2:DescribeInstances
操作 . 所以我添加了 AttachVolume
和 DetachVolume
动作:
{
"Sid": "kopsK8sEC2NodePerms",
"Effect": "Allow",
"Action": [
"ec2:DescribeInstances",
"ec2:AttachVolume",
"ec2:DetachVolume"
],
"Resource": [
"*"
]
},
这没有用 . 我还是得到了这个错误:
Attach failed for volume "myvolume" : Error attaching EBS volume "XXX" to instance "YYY": "UnauthorizedOperation: You are not authorized to perform this operation.
我错过了什么吗?

我找到了解决方案 . 它被描述为here .
在kops 1.8.0-beta.1中,主节点要求您使用以下标记标记AWS卷:
KubernetesCluster
:<clustername-here>
因此,有必要使用
awscli
创建带有该标记的EBS卷:或者您可以在
EC2
- >Volumes
- >Your volume
- >Tags
中手动标记它而已 .
