如何使用 Let's Encrypt SSL 和 Duck DNS 设置 Caddy 来为作为 Docker 容器运行的多项服务提供服务？

772

我已经成功设置了 VaultWarden，它只能通过 Caddy 在具有 lets encrypt SSL 证书的本地 LAN 上访问。Caddy、VaultWarden 和其他服务作为在 Raspberry Pi 主机上运行的 Docker 容器运行。

我已经设置了一个 Duck DNS 域：test111.duckdns.org它指向我的 Raspberry Pi 私有 LAN IP 地址。

我在 pfSense DNS 解析器设置中添加了主机覆盖（这是使其工作的关键步骤），如下所示：

Host: test111
Domain: duckdns.org
IP Address: <raspberry pi IP address>

我的 Docker 撰写文件：

networks:
  docker-mongoose:
    driver: bridge
    ipam:
      driver: default
      config:
        - subnet: "172.16.117.0/27"

  vaultwarden:
    image: vaultwarden/server:latest
    networks:
      docker-mongoose:
        ipv4_address: 172.16.117.8
    container_name: vaultwarden
    restart: always
    environment:
      DOMAIN: "https://test111.duckdns.org"
      SIGNUPS_ALLOWED: "false"
      INVITATIONS_ALLOWED: "false"
      SHOW_PASSWORD_HINT: "false"
      LOG_FILE: "/data/vaultwarden.log"
      LOG_LEVEL: "warn"
    volumes:
      - ./vw-data:/data # the path before the : can be changed
    #ports:
      #- 8888:80 # you can replace the 11001 with your preferred port

我的Caddy文件：

{$DOMAIN} {
    log {
        level INFO
        output file {$LOG_FILE} {
            roll_size 10MB
            roll_keep 10
        }
    }

    # Use the ACME DNS-01 challenge to get a cert for the configured domain.
    tls {
        dns duckdns {$DUCKDNS_TOKEN}
    }

    # This setting may have compatibility issues with some browsers
    # (e.g., attachment downloading on Firefox). Try disabling this
    # if you encounter issues.
    encode zstd gzip

    # Proxy everything to Rocket
    reverse_proxy vaultwarden:80
}

此设置运行良好，我可以通过 SSL 访问我的 VaultWarden https://test111.duckdns.org，它使用 Let's Encrypt 证书。我使用本指南来实现此目的。

但是我希望它能够使用 Caddy 提供多种 Docker 服务。例如，要访问 VaultWarden，我可以访问https://vaultwarden.test111.duckdns.org或https://service.test111.duckdns.org等。

我尝试使用通配符在 Caddyfile 中更改此设置：

# Wildcard SSL for all subdomains under the domain defined in the {$DOMAIN} variable
*.{$DOMAIN} {
    tls {
        dns duckdns {$DUCKDNS_TOKEN}
    }

    # Logs configuration (optional, adjust as necessary)
    log {
        level INFO
        output file {$LOG_FILE} {
            roll_size 10MB
            roll_keep 10
        }
    }

    # Default reverse proxy to a generic service if no specific service matches
    reverse_proxy service_default:80
}

# Vaultwarden Service
vaultwarden.{$DOMAIN} {
    reverse_proxy vaultwarden:80
    log {
        level INFO
        output file {$LOG_FILE} {
            roll_size 10MB
            roll_keep 10
        }
    }
}


unifi.{$DOMAIN} {
    reverse_proxy unifi-network-application:8443
    log {
        level INFO
        output file {$LOG_FILE} {
            roll_size 10MB
            roll_keep 10
        }
    }
}

我还在 pfSense 的 DNS 解析器设置中添加了主机覆盖，以便不同的服务指向我的 Docker IP 地址：

Host: unifi     
Domain: test111.duckdns.org     
IP Address: 172.16.117.9

Host: vaultwarden   
Domain: test111.duckdns.org     
IP Address: 172.16.117.8

它可以使用nslookup找到这些：

nslookup vaultwarden.test111.duckdns.org
Server:     127.0.0.53
Address:    127.0.0.53#53

Non-authoritative answer:
Name:   vaultwarden.test111.duckdns.org
Address: 172.16.117.8

然而这不起作用我无法访问我的 Docker 服务并且在我的 Caddy 容器中出现以下错误：

我本质上是想通过 Caddy 和 duck dns 来实现这一点。但我不确定这是否可行，或者我是否错误地配置了 Caddy。

我设法搞清楚了。事实证明，我需要将 PfSense 中的每个主机覆盖更改为托管每个服务的 Raspberry Pi 的本地 IP，而不是分配给每个服务容器的 docker 地址。经过此更改后，我的 DuckDNS 域似乎运行良好。
