AWS EKS添加仅限于名称空间的用户 [英] AWS EKS add user restricted to namespace

问题描述

我已经创建了AWS EKS集群，因为使用我的AWS userID创建的我已被添加到system:masters组.但是，当检查ConfigMap 我没有看到我的用户ID. 为什么?

I have created AWS EKS cluster since I have created using my AWS userID has been added to system:masters group. But when checked ConfigMap aws-auth I don't see my user ID. Why ?

我必须授予其他用户访问权限，所以我必须为IAM用户分配适当的AWS策略，然后使用以下映射编辑ConfigMap aws-auth

I had to give access to another user, so I have to assign appropriate AWS policies to the IAM user, then I edited the ConfigMap aws-auth with the following mapping

mapUsers:
----
- userarn: arn:aws:iam::573504862059:user/abc-user  
  username: abc-user
  groups:
    - system:masters

到目前为止，我了解到某个用户属于system:masters组的一部分时，该用户在群集上具有管理权限.

So far I have understood when a user is part of system:masters group, this user has admin privileges on the cluster.

如何将具有受限特权的新用户添加到特定名称空间?我是否需要为上述用户做同样的事情?如果是这样，那么我应该将新用户添加到哪个组?

How can I add a new user who will have restricted privileges to a specific namespace? Do I have to do the same thing what I have done for the above user? If so then what group I should add the new user to?

推荐答案

我会熟悉因此您可以创建Role，因为它们仅限于特定的名称空间.

So you can create a Role since these are limited to a specific namespace.

kind: Role
apiVersion: rbac.authorization.k8s.io/v1
metadata:
  namespace: my-namespace
  name: full-namespace
rules:
- apiGroups: ["*"] 
  resources: ["*"]
  verbs: ["*"]

然后创建一个RoleBinding:

$ kubectl create rolebinding my-namespace-binding --role=full-namespace --group=namespacegroup --namespace=my-namespace

或kubectl create -f此:

apiVersion: rbac.authorization.k8s.io/v1
kind: RoleBinding
metadata:
  name: my-namespace-binding
  namespace: mynamespace
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: Role
  name: full-namespace
subjects:
- apiGroup: rbac.authorization.k8s.io
  kind: Group
  namespace: mynamespace

然后在您的ConfigMap上:

Then on your ConfigMap:

mapUsers:
----
- userarn: arn:aws:iam::573504862059:user/abc-user  
  username: abc-user
  groups:
    - namespacegroup
