Traefik的TLS配置

生产环境的部署大多采用F5+ Traefik这种方式，因为Traefik的SSL方式相对来说比较慢，因此SSL更多的在F5上开放，而F5到Traefik之间以及后端都是http方式。

但客户需要在开发和测试环境直接用SSL，因此需要配置。

创建secret

kubectl create secret generic traefik-cert --from-file=ca-key.pem --from-file=ca.pem -n kube-system

创建configmap

defaultEntryPoints = ["http","https"]
[entryPoints]
  [entryPoints.http]
  address = ":80"
    [entryPoints.http.redirect]
      entryPoint = "https"
  [entryPoints.https]
  address = ":443"
    [entryPoints.https.tls]
      [[entryPoints.https.tls.certificates]]
      CertFile = "/ssl/ca.pem"
      KeyFile = "/ssl/ca-key.pem"

 kubectl create configmap traefik-conf --from-file=traefik.toml -n kube-system
