插件安装#

vela addon enable traefik

访问 Traefik 的 UI#

默认安装情况下 Traefik 无法直接访问,可通过 port-forward 进行本地代理,这仅适用于调试阶段。

vela port-forward -n vela-system addon-traefik

expected output:

Forwarding from 127.0.0.1:9000 -> 9000
Forwarding from [::1]:9000 -> 9000
Forward successfully! Opening browser ...
Handling connection for 9000

你可以通过 http://127.0.0.1:9000/dashboard/ 地址访问到 Traefik 的 UI 可视化面板。

设置网关流量接入方式#

如果你使用云上的集群,使用 LoadBalancer 暴露 Traefik 的访问入口是最佳方案。

vela addon enable traefik serviceType=LoadBalancer

如果在自建集群,需要根据你是作为集群网关还是应用网关来选择流量接入方式。
