This can be used in K3s, as K3s use traefik as the default ingress class.
We use basic-auth to control the access of kube-explorer. The auth token is stored in the secret.
The default user is niusmallnan, and password is dagedddd. You can replace to another value with htpasswd tool.
htpasswd -nb username password | base64
To install this mode, just run this script:
kubectl create -f ./middleware.yaml
export MY_IP=$(curl -sL ipinfo.io/ip)
envsubst < ./ingress.yaml.tpl | kubectl create -f -
