当使用“云提供商= AWS”与kubeadm KUBE-控制器管理器不启动

问题描述 投票:1回答:1

我试图使用与AWS Kubernetes整合,但KUBE-控制器经理不启动。 (顺便说一句:一切工作完全没有ASW选项)

这是我做的:

Ubuntu的@ IP-172-31-17-233:〜$更多/etc/kubernetes/aws.conf

apiVersion: kubeadm.k8s.io/v1alpha1
kind: MasterConfiguration

Ubuntu的@ IP-172-31-17-233:〜$更多/etc/kubernetes/cloud-config.conf

[Global]
KubernetesClusterTag=kubernetes
KubernetesClusterID=kubernetes

(我试过很多在这里的组合,根据我发现的例子,包括“ws_access_key_id”,“aws_secret_access_key”,省略的.conf,或者删除此文件,但没有奏效)

Your Kubernetes master has initialized successfully!

To start using your cluster, you need to run the following as a regular user:

  mkdir -p $HOME/.kube
  sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
  sudo chown $(id -u):$(id -g) $HOME/.kube/config

You should now deploy a pod network to the cluster.
Run "kubectl apply -f [podnetwork].yaml" with one of the options listed at:
  https://kubernetes.io/docs/concepts/cluster-administration/addons/

You can now join any number of machines by running the following on each node
as root:

  kubeadm join 172.31.17.233:6443 --token x8hi0b.uxjr40j9gysc7lcp --discovery-token-ca-cert-hash sha256:8ad9dfbcacaeba5bc3242c811b1e83c647e2e88f98b0d783875c2053f7a40f44

任何想法?我是新来Kubernetes,我不知道我能做些什么?

谢谢,米哈尔。

任何想法?

检查以下几点作为潜在的问题:

  • kubelet有适当的供应商设置,检查/etc/systemd/system/kubelet.service.d/20-cloud-provider.conf包含: Environment="KUBELET_EXTRA_ARGS=--cloud-provider=aws --cloud-config=/etc/kubernetes/cloud-config.conf 如果没有,添加并重新启动kubelet服务。
  • 在以下文件/etc/kubernetes/manifests/检查有适当的配置: kube-controller-manager.yamlkube-apiserver.yaml--cloud-provider=aws 如果不是,只是添加,荚会自动重新启动。
  • 为以防万一,检查AWS资源(EC2实例等)的标签与kubernetes标签(从cloud-config.conf拍摄)和IAM策略设置正确。

如果由阿尔乔姆在能够说明在这个问题上更多的光线意见要求,你可以提供日志。

Edit

的要求,在评论中,IAM策略操作简短的概述:

  • 创建新的IAM策略(或进行相应的编辑,如果已经创建),说k8s-default-policy。下面给出的是一个相当宽松的政策,你可以细粒度精确设置,以符合您的安全偏好。注意负载平衡器节你的情况。在描述装上去线沿线的“允许EC2实例调用代表您的AWS服务。”或类似的... { "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": "s3:*", "Resource": [ "arn:aws:s3:::kubernetes-*" ] }, { "Effect": "Allow", "Action": "ec2:Describe*", "Resource": "*" }, { "Effect": "Allow", "Action": "ec2:AttachVolume", "Resource": "*" }, { "Effect": "Allow", "Action": "ec2:DetachVolume", "Resource": "*" }, { "Effect": "Allow", "Action": ["ec2:*"], "Resource": ["*"] }, { "Effect": "Allow", "Action": ["elasticloadbalancing:*"], "Resource": ["*"] } ] }
  • 创建新角色(或approptiately编辑如果已经创建)和以前的政策重视它,说重视k8s-default-policyk8s-default-role
  • 附加到角色可以处理AWS资源实例。如果需要,您可以创建主及工人不同的角色。 EC2 - > Instances - >(选择实例) - > Actions - > Instance Settings - > Attach/Replace IAM Role - >(选择合适的角色)
  • 此外,除了这个检查有问题的所有资源都标记有kubernetes标签。
