I have got the following services: ubuntu@master:~$ kubectl get services --all-namespaces NAMESPACE NAME CLUSTER-IP EXTERNAL-IP PORT(S) AGE default kubernetes 100.64.0.1 443/TCP 48m kube-system kube-dns 100.64.0.10 53/UDP,53/TCP 47m kube-system kubernetes-dashboard 100.70.83.136 80/TCP 47m I am attempting to access kubernetes dashboard. The following response seems reasonable, taking into account curl is not a browser. ubuntu@master:~$ curl 100.70.83.136 Kubernetes Dashboard According to the documentation the right access point is https://localhost/ui. So, I am trying it and receive a bit worrying result. Is it expected response? ubuntu@master:~$ curl https://localhost/ui curl: (60) server certificate verification failed. CAfile: /etc/ssl/certs/ca-certificates.crt CRLfile: none More details here: http://curl.haxx.se/docs/sslcerts.html curl performs SSL certificate verification by default, using a "bundle" of Certificate Authority (CA) public keys (CA certs). If the default bundle file isn't adequate, you can specify an alternate file using the --cacert option. If this HTTPS server uses a certificate signed by a CA represented in the bundle, the certificate verification probably failed due to a problem with the certificate (it might be expired, or the name might not match the domain name in the URL). If you'd like to turn off curl's verification of the certificate, use the -k (or --insecure) option. Trying the same without certificate validation. For curl it might be OK. but I have got the same in a browser, which is connecting though port forwarding via vagrant forwarded_port option. ubuntu@master:~$ curl -k https://localhost/ui Unauthorized What I am doing wrong? and how to make sure I can access the UI? Currently it responds with Unauthorized. The docs for the dashboard tell the password is in the configuration: ubuntu@master:~$ kubectl config view apiVersion: v1 clusters: [] contexts: [] current-context: "" kind: Config preferences: {} users: [] but it seems I have got nothing... Is it expected behavior? How can I authorize with the UI?
