【问题描述】：
我正在尝试使用 Let's Encrypt SSL 证书为 HTTPS 部署带有 Docker 的 Node.js/Express 应用程序。
当我运行 docker-compose up 命令时，所有 3 个服务都已启动，但我注意到这样的警告：
Saving debug log to /var/log/letsencrypt/letsencrypt.log
No certs found.
当 docker 尝试在 certbot/Dockerfile 文件中执行 RUN /scripts/certbot-auto -n certificates 命令时会出现此警告。
在/var/log/letsencrypt/letsencrypt.log 文件中我看到了这个：
2019-08-21 10:27:50,354:DEBUG:certbot.main:certbot version: 0.37.1
2019-08-21 10:27:50,355:DEBUG:certbot.main:Arguments: ['-n']
2019-08-21 10:27:50,355:DEBUG:certbot.main:Discovered plugins: PluginsRegistry(PluginEntryPoint#apache,PluginEntryPoint#manual,PluginEntryPoint#nginx,Plugin$
2019-08-21 10:27:50,372:DEBUG:certbot.log:Root logging level set at 20
2019-08-21 10:27:50,372:INFO:certbot.log:Saving debug log to /var/log/letsencrypt/letsencrypt.log
在 nginx 容器的日志中我也注意到了这样的警告：
2019/08/21 10:28:37 [emerg] 1#1: cannot load certificate "/etc/letsencrypt/live/tols/fullchain.pem": BIO_new_file() failed (SSL: error:02001002:system library:fopen:No such file or directory:fopen('/etc/letsencrypt/live/tols/fullchain.pem','r') error:2006D080:BIO routines:BIO_new_file:no such file)
问题：据我了解，没有创建 ssl 证书。如何解决此问题并使用 certbot 正确安装证书？

您好 Nurzhan，您的结构中的 fullchain.pem 文件在哪里？在您提到的 nginx 旁边的任何脚本中，如果您的 certbot 服务依赖于 nginx，您可以在 yml 中使用 depends_on
