I have a problem with Kubernetes depoyment. Can anybody help I always get this error when trying to connect to the cluster IP - authentication

Question

I have problems with Kubernetes. I try to deploy my service for two days now bu I'm doing something wrong.
{
"kind": "Status",
"apiVersion": "v1",
"metadata": {
},
"status": "Failure",
"message": "forbidden: User \"system:anonymous\" cannot get path \"/\": No policy matched.",
"reason": "Forbidden",
"details": {
},
"code": 403
}
Does anybody knows what the problem could be?
Here is also my yaml file:

Can anybody help me with this? I'm stuck and I've no idea what could be the problem. This is also my first Kubernetes project.

Answer 1

"message": "forbidden: User \"system:anonymous\" cannot get path \"/\": No policy matched.",
.. means just what it says: your request to the kubernetes api was not authenticated (that's the system:anonymous part), and your RBAC configuration does not tolerate the anonymous user making any requests to the API
No one here is going to be able to help you straighten out that problem, because fixing that depends on a horrific number of variables. Perhaps ask your cluster administrator to provide you with the correct credentials.

Answer 2

I have explained it in this post. You will need ServiceAccount, ClusterRole and RoleBinding. You can find explanation in this article. Or as Matthew L Daniel mentioned in the Kubernetes documentation.
If you still have problems, provide the method/tutorial you have used to deploy the cluster (as "Gitlab Kubernetes integration" does not tell much on the method you have used).
