Dashboard URL (change IP address): https://116.203.232.90:16443/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/#/statefulset?namespace=default
Obtain user and password from cat /var/snap/microk8s/current/credentials/basic_auth.csv
Bearer Token for Dashboard itself:
token=$(microk8s kubectl -n kube-system get secret | grep default-token | cut -d " " -f1)
microk8s kubectl -n kube-system describe secret $token
mkdir /etc/microk8s
microk8s.config > /etc/microk8s/microk8s.conf
Download the file /etc/microk8s/microk8s.conf to $HOME/.kube/config-m8s (or any other filename).
Tell the kubectl command to read the additional config file via export KUBECONFIG=$HOME/.kube/config:$HOME/.kube/config-m8s (this ENV variable defines a list of config files that kubectl will use). Add this to your .bashrc or similar to make it permanent.
