如何在Kubernetes集群中创建用户?

我正在尝试在Kubernetes集群中创建一个用户。

我用我的一个地形脚本在DigitalOcean上旋转了两个水滴。

ssh :

doctl compute ssh droplet1

kubectl create namespace thalasoft

我在中创建了一个用户角色 role-deployment-manager.yml 文件:

kind: Role
apiVersion: rbac.authorization.k8s.io/v1beta1
metadata:
  namespace: thalasoft
  name: deployment-manager
rules:
- apiGroups: ["", "extensions", "apps"]
  resources: ["deployments", "replicasets", "pods"]
  verbs: ["get", "list", "watch", "create", "update", "patch", "delete"]

kubectl create -f role-deployment-manager.yml

我在 rolebinding-deployment-manager.yml 文件:

kind: RoleBinding
apiVersion: rbac.authorization.k8s.io/v1beta1
metadata:
  name: deployment-manager-binding
  namespace: thalasoft
subjects:
- kind: User
  name: stephane
  apiGroup: ""
roleRef:
  kind: Role
  name: deployment-manager
  apiGroup: ""

并执行命令: kubectl创建-f rolebinding-deployment-manager.yml

这是我的终端输出:

Last login: Wed Dec 19 10:48:48 2018 from 90.191.151.182
root@droplet1:~# kubectl create namespace thalasoft
namespace/thalasoft created
root@droplet1:~# vi role-deployment-manager.yml
root@droplet1:~# kubectl create -f role-deployment-manager.yml
role.rbac.authorization.k8s.io/deployment-manager created
root@droplet1:~# vi rolebinding-deployment-manager.yml
root@droplet1:~# kubectl create -f rolebinding-deployment-manager.yml
rolebinding.rbac.authorization.k8s.io/deployment-manager-binding created
root@droplet1:~# 

现在,我想首先在集群中创建一个用户,然后配置客户机 kubectl 使用此用户,以便从我的笔记本电脑进行操作,并避免通过 ssh̀ 到水滴。

我知道我可以在中配置用户 库贝特尔 客户:

# Create a context, that is, a user against a namespace of a cluster, in the client configuration
kubectl config set-context digital-ocean-context --cluster=digital-ocean-cluster --namespace=digital-ocean-namespace --user=stephane

# Configure the client with a user credentials
cd;
kubectl config set-credentials stephane --client-certificate=.ssh/id_rsa.pub --client-key=.ssh/id_rsa

但据我所知,这只是一些客户端配置。

# Create a private key
openssl genrsa -out .ssh/thalasoft.key 4096
# Create a certificate signing request
openssl req -new -key .ssh/thalasoft.key -out .ssh/thalasoft.csr -subj "/CN=stephane/O=thalasoft"
# Sign the certificate
export CA_LOCATION=/etc/kubernetes/pki/
openssl x509 -req -in .ssh/thalasoft.csr -CA $CA_LOCATION/ca.crt -CAkey $CA_LOCATION/ca.key -CAcreateserial -out .ssh/thalasoft.crt -days 1024

# Configure a cluster in the client
kubectl config set-cluster digital-ocean-cluster --server=https://${MASTER_IP}:6443 --insecure-skip-tls-verify=true

# Configure a user in the client
# Copy the key and the certificate to the client
scp -o "StrictHostKeyChecking no" root@165.227.171.72:.ssh/thalasoft.* .
# Configure the client with a user credentials
kubectl config set-credentials stephane --client-certificate=.ssh/thalasoft.crt  --client-key=.ssh/thalasoft.key
# Create a context, that is, a user against a namespace of a cluster, in the client configuration
kubectl config set-context digital-ocean-context --cluster=digital-ocean-cluster --namespace=digital-ocean-namespace --user=stephane
