Traefik v1.7 静态证书和动态 acme 证书

Question

我在 docker 中以 swarm 模式使用 traefik:1.7.6-alpine。我需要指定静态 ssl 证书和其他自我管理的 acme 证书。

这是我在提升容器时遇到的错误：

这是我的 traefik.toml

debug = true
logLevel = "INFO"
defaultEntryPoints = ["http", "https"]
[entryPoints]
    [entryPoints.http]
        address = ":80"
    [entryPoints.https]
        address = ":443"
        [entryPoints.https.tls]
            [[entryPoints.https.tls.certificates]]
                certFile = "/path/to/first/first.crt"
                keyFile = "/path/to/first/first.key"
            [[entryPoints.https.tls.certificates]]
                certFile = "/path/to/second/second.crt"
                keyFile =  "/path/to/second/second.key"
[api]
  dashboard = true
  [api.statistics]
    recentErrors = 10
[docker]
  exposedbydefault = false
  watch = true
  domain = "mydomain.com"

[acme]
email = "myemail@gmail.com"
storage = "/etc/traefik/acme/acme.json"
entryPoint = "https"
acmeLogging = true
onHostRule = true
    [acme.httpChallenge]
       entryPoint = "http"
    [[acme.domains]]
       main = "third-site.com"

这就是我在 docker-compose 中挂载 acme.json 文件以保留生成的证书的方式：

volumes:
./traefik/acme/acme.json:/etc/traefik/acme/acme.json

acme.json 文件具有 600 权限和所有者 root:root。

除了显示的配置之外，我尝试过的无法生成证书的事情：

1. 不映射 acme.json 文件，而是映射父文件夹，以便 traefik 创建 acme.json 文件 （失败）
2. 不要为 acme.json 映射任何卷，以免在移除容器时丢失。 （失败）
3. 将文件 acme.json 的所有者更改为 myuser:myuser，因此从容器中用户 1000 显示为所有者 （失败）

Answer 1

我能够解决错误的方法：“无法读取新帐户，ACME数据转换不可用：JSON输入意外结束”，在文件中写入 acme.json {}，显然在尝试读取空文件并将其解析为 json 时出错。

总结： 在要映射的主机上创建 acme.json 时，您必须这样做：

touch acme.json
echo '{}'> acme.json
chmod 600 acme.json
