20.38.1. Knowledge Base Article: kb-00037

20.38.2. Description

How to use the Kubernetes Dashboard when provisioning via the KRIB content pack.

20.38.3. Solution

For Installing KRIB (Kubernetes Rebar Integrated Bootstrapping), the admin.conf files is saved into the krib/cluster-admin-conf profile parameter and can be downloaded after installation is complete. Using this file kubectl --kubeconfig=admin.conf allows autheticated access to the cluster. Please see the KRIB documentation for more details.

For other deployments such as Ansible Kubespray or the Kubeadm deployments of Kubernetes are all maintained by the respective Kubernetes communities. Digital Rebar simply implements a basic version of those configurations. Access to the Kubernetes Dashboard is often changing, and being updated by the community. Please check with the respective communities about how to correctly access the Dashboard.

Some things to note in general:

  • Access is restricted; as well it should

  • You must configure/enable access to the Dashboard

  • Our implmentations usually have a mechanism configured, but this changes over time

Some things that have worked in the past:

  • kubectl proxy - enabled Proxy access to the Kubernetes Master to get to the Dashboard

  • try stopping the Proxy container, and running kubectl proxy --address --accept-hosts '.*'
    • carefully consider this implication - you are enable access from all hosts !!!

  • any other solutions, please let us know… we’ll add them here
