I can collect node data, but k8s can't

the configuration

```auto
- module: kubernetes
  metricsets:
    - node
    - system
    - pod
    - container
    - volume
  period: 10s
  host: ${NODE_NAME}
  hosts: ["https://${NODE_IP}:10250"]
  bearer_token_file: /var/run/secrets/kubernetes.io/serviceaccount/token
  ssl:
    verification_mode: none
    certificate_authorities:
      - /var/run/secrets/kubernetes.io/serviceaccount/ca.crt

```

the log

```auto

Hi!

Do you actually want to use `ssl`? If so you need to make sure that you are using the right certificates.  
If not you can just comment out these lines:

```auto
- module: kubernetes
  metricsets:
    - node
    - system
    - pod
    - container
    - volume
  period: 10s
  host: ${NODE_NAME}
  hosts: ["https://${NODE_IP}:10250"]
  bearer_token_file: /var/run/secrets/kubernetes.io/serviceaccount/token
  ssl:
    verification_mode: none
    #certificate_authorities:
    # - /var/run/secrets/kubernetes.io/serviceaccount/ca.crt

```

See [https://github.com/elastic/beats/blob/f2956098ef62b0fec1ae02e7cb9659dd6b9e6fe9/deploy/kubernetes/metricbeat-kubernetes.yaml#L116](https://github.com/elastic/beats/blob/f2956098ef62b0fec1ae02e7cb9659dd6b9e6fe9/deploy/kubernetes/metricbeat-kubernetes.yaml#L116)

sorry for reply later  
I tried your suggestion, but it didn't work

```auto
- module: kubernetes
  metricsets:
    - node
    - system
    - pod
    - container
    - volume
  period: 10s
  namespace: 'sxc'
  host: ${NODE_NAME}
  hosts: ["https://localhost:10250"]
  bearer_token_file: /var/run/secrets/kubernetes.io/serviceaccount/token
  ssl.verification_mode: "none"

```
