https://stackoverflow.com/questions/68565048/how-to-expose-traefik-v2-dashboard-in-k3d-k3s-via-configuration
方式1.
kubectl port-forward -n kube-system $(kubectl get pods --selector "app.kubernetes.io/name=traefik" --output=name -n kube-system) 9000:9000
结论：成功，但只能本机访问，其次命令行必须一直运行，需要新开终端测试
方式2
# dashboard.yaml
apiVersion: traefik.io/v1alpha1
kind: IngressRoute
metadata:
name: dashboard
spec:
entryPoints:
- web
routes:
- match: Host(`traefik.localhost`) && (PathPrefix(`/dashboard`) || PathPrefix(`/api`))
kind: Rule
services:
- name: api@internal
kind: TraefikService
结论：没弄成功，可能操作方式不对，目测也是只能本机访问。
方式3
在k3s的部署目录新增HelmChartConfig清单来自定义 Traefik.
cat >> /var/lib/rancher/k3s/server/manifests/traefik-config.yaml << EOF
apiVersion: helm.cattle.io/v1
kind: HelmChartConfig
metadata:
name: traefik
namespace: kube-system
spec:
valuesContent: |-
dashboard:
enabled: true
ports:
traefik:
expose: true # this is not recommended in production deployments, but I want to be able to see my dashboard locally
logs:
access:
enabled: true
EOF
结论：成功，且可以远程访问，但不推荐，对于外部公开集群信息且无需安全验证，危害是极大的。
