kubernetes localhost:8080 被上下文拒绝
kubernetes localhost:8080 was refused with context
Kubernets 集群是使用阿里巴巴容器服务设置的,使用 root 帐户访问集群没有问题,当创建新的命名空间并将用户添加到该命名空间时,它会抛出错误 与服务器的连接 localhost:8080 被拒绝
这是故障排除的设置
定义命名空间 dev 并使用 get verb 显示所有 kubernetes 命名空间。
root@kube-master:# kubectl get namespaces
NAME STATUS AGE
default Active 14d
dev Active 56m
kube-public Active 14d
kube-system Active 14d
在 Kubernetes 集群中添加了新上下文。
kubectl config set-context dev --namespace=dev --user=user1
当使用带有此配置文件的 kubectl CLI 时,我应该得到一个 访问被拒绝的错误
root@kube-master:/home/ansible# kubectl --context=dev get pods
The connection to the server localhost:8080 was refused - did you specify the right host or port?
而不是显示 与服务器的连接 localhost:8080 被拒绝
没有 --context 它工作得很好
root@kube-master:# kubectl get pods -n dev
NAME READY STATUS RESTARTS AGE
busybox 1/1 Running 1 1h
这是 kubernetes 配置视图

我明白了,当我执行命令时我注意到了什么
kubectl config view
集群显示为空
- context:

要解决此问题,添加了 --cluster
信息并修改了 set-context
root@kube-master:/home/ansible# kubectl config set-context dev --cluster=kubernetes --namespace=dev --user=user1
Context "dev" modified.
并且上下文设置正确
contexts:
- context:
cluster: kubernetes

并且在使用 --context=dev
查找 pods 时我得到了想要的结果
root@kube-master:/home/ansible# kubectl --context=dev get pods
No resources found.
