Question

我正在尝试在我的kubernetes集群上部署logstash。我正在使用k8s v1.6.1和calico作为网络。

我遇到的问题是pod正在启动但似乎无法注册DNS，我出于安全目的剥离了我的域名：

route53-kubernetes-551223410-wf89w route53-kubernetes W0516 19:47:32.715753       1 service_listener.go:151] Couldn't find destination zone: No zone found for MYWEBSITEURLHERE.com: AccessDenied: User: arn:aws:sts::056146032236:assumed-role/nodes.k8s-uw2.MYWEBSITEURLHERE.com/i-01cac4656e7ee0c4e is not authorized to perform: route53:ListHostedZonesByName
route53-kubernetes-551223410-wf89w route53-kubernetes   status code: 403, request id: 809c62fa-3a70-11e7-bccf-9daca39d7850

现在奇怪的是，我已经确认已为该角色正确设置了IAM信誉：

{
    "RoleName": "nodes.k8s-uw2.MYWEBSITEURLHERE.com",
    "PolicyDocument": {
        "Statement": [

            },
            {

                    "route53:ListHostedZonesByName"
                ]
            },
            {
                "Effect": "Allow",
                "Resource": [
                    "arn:aws:route53:::change/*"
                ],
                "Action": [
                    "route53:GetChange"
                ]
            },
            {
                "Effect": "Allow",
                "Resource": [
                    "*"
                ],
                "Action": [
                    "route53:ListHostedZones"
                ]
            },
            {
                "Effect": "Allow",
                "Resource": [
                    "arn:aws:s3:::k8s-uw2-sightmachine-com-state-store/k8s-uw2.MYWEBSITEURLHERE.com",
                    "arn:aws:s3:::k8s-uw2-sightmachine-com-state-store/k8s-uw2.MYWEBSITEURLHERE.com/*"
                ],
                "Action": [
                    "s3:*"
                ]
            },
            {
                "Effect": "Allow",
                "Resource": [
                    "arn:aws:s3:::k8s-uw2-sightmachine-com-state-store"
                ],
                "Action": [
                    "s3:GetBucketLocation",
                    "s3:ListBucket"
                ]
            }
        ],
        "Version": "2012-10-17"
    },
    "PolicyName": "nodes.k8s-uw2.MYWEBSITEURLHERE.com"
}

还有什么奇怪的是我能够创建我的弹性搜索服务以及kibana，而且这些服务都很好。这只是我的logstash服务不好玩。

这是我的logstash服务定义：

apiVersion: v1
kind: Service
metadata:
  name: logstash
  namespace: inf
  labels:
    app: logstash
    component: server
    role: monitoring
    dns: route53
  annotations:
    domainName: logstash.k8s-uw2.MYWEBSITEURLHERE.com
    service.beta.kubernetes.io/aws-load-balancer-internal: 0.0.0.0/0
spec:
  type: LoadBalancer
  selector:
    app: logstash
    component: server
    role: monitoring
  ports:
  - name: lumberjack
    port: 5043
    protocol: TCP
  - name: beats
    port: 5044
    protocol: TCP
  - name: http
    port: 31311
    protocol: TCP

这是我的弹性搜索服务定义：

apiVersion: v1
kind: Service
metadata:
  name: elasticsearch
  namespace: inf
  labels:
    app: elasticsearch
    component: client
    role: monitoring
    dns: route53
  annotations:
      domainName: elasticsearch.k8s-uw2.sightmachine.com
      service.beta.kubernetes.io/aws-load-balancer-internal: 0.0.0.0/0
spec:
  type: LoadBalancer
  selector:
    app: elasticsearch
    component: client
    role: monitoring
  ports:
  - name: http
    port: 9200
    protocol: TCP

我也确认ZONE ID确实是正确的。

任何帮助都会非常受欢迎，因为大部分内容都是从传统设置中抽象出来的，而且我很难调试。

解决这个问题的方法只是为了增加允许的访问控制量，所以不要让那个角色像下面那样：

"arn:aws:route53:::hostedzone/Z1ILWH3JAW6GTW"
"arn:aws:route53:::change/*"

成为：

找不到目的地区域：找不到MYWEBSITEURLHERE.com的区域：AccessDenied：
