Kubernetes: Open /certs/tls.crt: no such file or directory

I am trying to configure SSL for the Kubernetes Dashboard. Unfortunately I receive the following error:

2020/07/16 11:25:44 Creating in-cluster Sidecar client
2020/07/16 11:25:44 Error while loading dashboard server certificates. Reason: open /certs/tls.crt: no such file or directory

volumeMounts:
            - name: certificates
              mountPath: /certs
              # Create on-disk volume to store exec logs

I think that /certs should be mounted, but where should it be mounted?

Certificates are stored as secrets. Then secret can be used and mounted in a deployment.

So in your example it would look something like this:

...
          volumeMounts:
            - name: certificates
              mountPath: /certs
              # Create on-disk volume to store exec logs
...
      volumes:
        - name: certificates
          secret:
            secretName: certificates
...

This is just a short snipped of the whole process of setting up Kubernetes Dashboard v2.0.0 with recommended.yaml.

If you did used the recommended.yaml then certs are created automatically and stored in memory. Deployment is being created with args : -auto-generate-certificates

I also recommend reading How to expose your Kubernetes Dashboard with cert-manager as it might be helpful to you.

There already was an issue submitted with a simmilar problem as yours Couldn't read CA certificate: open : no such file or directory #2518 but it's regarding Kubernetes v1.7.5

If you have any more issues let me know I'll update the answer if you provide more details.
