docker - 带有 Letsencrypt 的 Traefik V2.0 无法为域生成证书

Question

我正在使用 Whoami 进行测试，但在生成证书时遇到问题。

没有证书生成到 acme.json 文件中，站点使用的是来自 Traefik 的默认证书，导航器认为该证书无效。

这里是错误:

traefik         | time="2019-10-14T21:16:15Z" level=error msg="Unable to obtain ACME certificate for domains \"inner-whoami.mysite.com\": unable to generate a certificate for the domains [inner-whoami.mysite.com]: acme: Error -> One or more domains had a problem:\n[inner-whoami.mysite.com] acme: error: 403 :: urn:ietf:params:acme:error:unauthorized :: Invalid response from https://inner-whoami.mysite.com/.well-known/acme-challenge/xxxxxxxxxxxxxxxxxxxx [51.75.207.100]: \"Hostname: xxxxxxxxxx\\nIP: 127.0.0.1\\nIP: 172.18.0.2\\nRemoteAddr: 172.18.0.3:55692\\nGET /.well-known/acme-challenge/xxxxxxxxxx\", url: \n" rule="Host(`inner-whoami.mysite.com`)" routerName=inner-whoami-secured providerName=myhttpchallenge.acme

这是 docker-compose.yml 文件。一切都在里面。如您所见，这是为进一步部署做准备的测试。不是实际的生产文件。我需要解决这个问题才能在 Traefik 服务器范围内使用...

Answer 1

您可能需要将 http 挑战的入口点从 web-secure 更改为 web，即:

- "--certificatesresolvers.myhttpchallenge.acme.httpchallenge.entrypoint=web"

或者使用TLS Challenge相反:

-“--certificatesresolvers.myhttpchallenge.acme.tlschallenge=true”
